merry Christmas to all

Merry Christmas to all

and a happy New Years too

Wednesday, December 22, 2010


wow its Christmas again already, sure dose not take that long, i have been involved in my project for the better part of a year now. i have been watching this project for much longer than that. but i am doing my best to add what ever contributions that i can.

i have learned allot through out this whole process, about electronics, soldering and designing some of the things that i have needed. so over all i am very glad for this experience, and i am planning on doing my best to see it to fruition.

i still have allot to learn so far too though, but i am getting there bit by bit, and i hope i can find a few more small things i need in calgary, or so i hope at the very lease, i am glad i do not need a bunch more things. if i can get 2 more scanners to scavenge for parts i should be able to find what i need.

i have been working on my one frame idea a little i will have more up on thingiverse tomorrow or the day after.

i hope i can find some ribbon cable, it would make running some of the cables i need to make allot less trouble.

i thought it would be handy if i made a break out board for my arduino mega.

i will make the cables i need for it tomorrow, i thought it would be less trouble if i did it this way

that is the extruder mounted onto my printer frame

repsnapper testing

seeing how i got my hot end all together, and working i was able to test it with repsnapper and tonokip firmware, i was able to test to see if hot end was not only working but able to extrude, and it did. so i am happy.

it heated up good, though i did notice that has it got closer to 200 the slower it got, though it still only took a short time, i think that was normal. but it was good too see that it is all working and reading the temps right.

i do like the setup that maker gear has, but for some reason i am always thinking things are going to be bigger. maybe it is just me but i always find it surprising.

i was hoping that i could find some pid code out there for thermistors, i was thinking about trying to get it to try to turn on a fan if it got too hot. i just need to get better at my coding i think.

woot i got the package

woot i got my operators super pack from maker gear today and i was able to get most of it done, i would like to know where i could find more of that black silicone and fiberglass insulation they have in the kit i can think of a few other uses for that stuff if i can find it in larger sizes.

but i will post more when i am not so tired

i am getting the idea to mount a small heat sink to the top of the brass tube, to help keep things a little cooler up there. but i like what i am seeing so far.

heated printing bed

today at work i found a 12v dc heated coffee mug, for less than 3 bucks so yay,

so i am thinking i can use it to make a hot bed for printing, it is a thicker nichrome wire, and on the box it says up to 72c at 12v on a car, so i am thinking that on a 12v computer PSU, i think it will get up to about 60c i think,  that should be enough to make a hot bed i think.

this is the box from the mug

that is the mug nothing special really.

this was the nichrome wire that was wrapped around the bottom of the 
insert of the mug, kinda scary that they had masking tape holding it onto the mug,

say hi to rara, my wifes dog, 

she is a very courious dog at times, and likes to play games that involve running away 
i am also starting to get more of the plywood up on the walls now too.

i also now have the last of my insulation in the walls now, i just need to put plastic over it, i will do that friday.
so i hope that after xmas i can finish the wood and start working in the shed,

but with all this i am making progress, so i am happy

getting there crazy idea part doux

well today i was able to get some more of my idea done, all whial having some tunes playing in the back ground. yay for logitech headsets. but here is the finished frame

i think this is a good start there are a few way to make it more printer friendly like adding in some circles or triangle so that there is less mass to print out,  i will keep at it here, but i think i can design a working printable frame based on this idea

a crazy idea

i was reading on the reprap forums today and i saw a post that mentioned printable rods and then for some reason that got me brain going on one of its tangents,  and i ended up designing this today

i think with just these pieces you could make a printable chassis for a repstrap in order for it to work i know i would have to work on my distances in order to get all the pieces to fit right but it was the start of the idea any how i may try to work on it a bit more tonight and this week but i do think it is an idea that could work, i would welcome any help with this idea, i have tried to make it all printable, it is poster here too if you want the file

i know that i might have to change it a bit more to make it a little more stiff, but that could also be done after it was build cheaply enough too.

work desk

I was able to get a few more things done on the shed today, i was able to build my work/computer desk in it, i plan on putting my repstrap in there when it is all said and done.

the shed is now keeping in its heat allot better now. not nearly so cold in it once i got the heater going, but when i first got into it, it was bloody cold. but now i also have the poly up on one more wall.

there is the desk that i built today, nice and level. and i hope about the right hight.

but this weekend and next week i hope to get a few more things done on my repstrap, i will get the Z axis mounted, i found some wood that will work for me i think. i just need to measure it again. and i will have to make another motor mount too. i am a little worried about how much torque that i am going to need though i think i might need more gearing, or if i should just bite the bullet and order that one geared stepper from makergear. i may just do that, and be done with it.

but i hope my hot end gets here next friday or so. i am looking forward to getting it together and tested.

Z axis

i have found something that i think should work for my Z axis they are lifts for cutting wood, they had rollers in the top that in time i may have a use for. i will be mounting them a little lower than that but i thought i would give you a idea of how i am going to mount them.

i have them on both sides, i was not sure how stable 1 was going to be 

and here we have the plate that i am using for Y axis base, i still do need to get that one worked out still but i think i still have more time for him, i am just happy to be getting closer to my goal.

here is one before i took the roller off and turned the top bracket around. they way they were setup they had an ark to there travel, not just straight up and down. by turning it around the slides are now both on the same side, i am not sure if there was another reason for that just yet, but i thought i would try any how. 

there was some play on the stops there so i added a washer i had seems to be working so far, but it did make them a little harder to turn, i hope some grease might help solve that issue.

here is what they looked like after, with the rollers removed and the top bracket turned around.

With all of this i hope that i will have a mostly working Z axis, i still need to figure out how to attach pullies to it but i will try to tackle that one after i get them mounted a little lower on the frame. i am not sure just how accurate they will be but i hope more than enough for me to print the parts i want to make a proper unit. but only time will tell on that front.

i am also thinking i might just try to mount my Y axis right to the bars in there already, seeing how if i get them mounted nice and parallel they would work great and save me allot of trouble. though they are a bit confined for space.

on another front i am getting to be more at ease with using  S4A from my last post. i like it so far, i am trying to figure out how to get it to read a thermistor still but i have not given up on that one just yet. i find it to work well for me, but i am also finding it constraining still. i hope they can find i way to support more code soon, and so that i can use more of my PWM pins it is very limiting in that regard still.

that and i am hoping they support more arduinos here soon i would like to see what i could do with my mega,

visual programming

suffice it to say that i am not the most adept at programing, parts of my brain know when they want to do and well the other parts seem to have better things to do. but today i found 2 very cool tools for people out there like me, i found these in the arduino blog so i have to give the original blogger credit for finding these in the first place i wish i knew who he was but here is the link but from there i was able to find these i do like this one so far, but i do find it a little limiting in how i am using, i still need to get a few more things straight but for me it is working good, but i do like a little more raw control. but you can use this one today, over the next few days i do plan on using it more. and seeing what i can learn with it. but the one thing i did not like about it too much is that it needs to always be connected to the arduino, i don't like that so much but for now it is a great way for me to learn.

but this one i want to try allot too, it looks like just what i have been waiting for. it looks to be allot like the other one, but i think it will allow me to control the inputs and outputs the way i want. and here is there main site

this one is still in the middle of testing, but i have signed up for it. i do like what i see allot more on this one, and i dont think it will always need to be connected. that is something that i do need and want.

i would love to know if modkit can import sketches from the arduino SDK if so i am looking forward to seeing how the reprap firmware looks like.

this is a quick screen capture of S4A, so that i could show you.
 i was trying to edit that one so that it would have a random spot in it, and i did get it to work, 

but for me this is one big blessing, it will mean i can do that much more. so i am happy with it, and i hope a few others out there will find this post useful has well.

over all a very good night for me,

one more order placed

yay one more order placed today for parts.

Today at lunch i placed an order at for there operator super back .40mm hybrid. i was hoping to make my own but due to difficulty with sourcing materials and not having the proper tools, i thought this would be the best option. from what i can see on the web allot of people like there setup and i figured i would try it and see how it works for me. but i am also liking the thought of being that much closer to printing too.

i hope in the next week or so i can start testing building and testing a few more of my idea, so i hope i can get my repstrap working here again sooner than later. but i will have to test out my ideas to see what will work for me. but i will see both what i can find and what i can build. though i will say this dose leave me wishing that i had a few more of the tools i need, but this xmas i hope to buy a drill press, and that will go a long way for me too. the other tool that would help me allot is a table saw. so i hope to buy one of them closer to my bday. or at least i hope.

 i hope makergear ships on Monday. i am eager to get back to trying to get things working.

i have got my idea down now to find a way to build it.

today i finally got to trying to get my idea down for my repstrap, if i do it right, it will give me all the pieces i need, with little effort, i just need to find a way to get it out on paper.

 this is the top and bottom plate.

 here i made a middle place y axis it is pretty much just a copy of the top one 
but if i can get this idea to work and figure out how to mount my bearing  to it i think this may work, i am going to talk to a local sign shop and see if this would work with anything they have there now. or at the very least i will try to get the files in a format so they could print me out some sort of template to cut with.

but i do think this is a good way to go this way all my holes should be lined up nice and stright, and it is an easy way to mount a few more things i just hope that i can find a way to do it fairly soon,

my only other issue with this is that i need to find a way to attach the bearings i need to it some how

i wonder if ponoko could even cut these out for me. lexan would look cool but i know it is not always the best to work with.

it is posted here too

one more wall insulated

the other day i got some more insulation for my shed, i was able to finish the roof and one more wall is nearly done. i just have a few small things left to do on it. like put in a pipe so that i can bring my power in through it. 
and patch up the insulation a little more.

 there was a few bats of the pink insulation left in there so i thought i would just leave them in there for now.
 i have the lights in the roof now, it has made id allot better to work in there now that i don't have to worry about that hot work light, and its short power chord

i need to take down that one bench still, i hope i can buy more wood soon at least it is allot cheaper than buying the insulation,  

i also now have an idea on how i can get my repstrap working again i am going to try to move a few more things around on in and see if i cant improve the layout so that i cant get it working better. i hope the idea works i guess i will find out soon enough though.

i have also been thinking it may be a good idea to figure out a way to add in thermal safety into the extruder hot end. i have been noticing allot of posts about bad hot ends, so i wonder what could be done to make some sort of safety into it,  but i am starting so see the benifits of using 1/2 copper pipe too, that would solve allot of issues too.

shed and ideas

i am making progress on my shed still. i now have 3 lights wired up to a plug. in time i will wire a panel into it, so that all my lights and a power outlets will be done properly, but that will be after i get all the insulation and walls done. but what i have is now i nice start, seeing how i dont need to have my work light on now, it is allot nicer of a light in there now, not so bright in one spot, so that will make working allot nicer.

i will also start trying to build a few idea for my Z axis here in the next few days to see if they will work, but it would be allot less trouble if i had a drill press. it is getting to be very annoying difficult to build what i need without one. i am going to try using a 2x4 and putting 2 bearing in it, one at the top and bottom of it, that will give much better support for the threaded rod, but i will need to make sure it is straight now in order for that to work. any wobble in the rod and it will be very bad for printing. another thing i am looking into is copper pipe, if i can figure out how to mount bearings onto it. so i still have more work cut out for me. but i am getting there.

i will be starting to make a hard case design for my dso nano here soon, one so that i have storage for my probes in it, the one it comes with dose not have anything for its probes. i will post it on thingiverse when i get it done.

Pipe strap

i am starting to think i might try to build a pipe strap, or seeing if i cant build what i need from plumbing parts. it is a idea that i think can work for me. even if i just build the Z axis out of it and find a way to attach it to my current chassis. so i am going to have to work a little on this idea.

i have also been thinking about going to a dorkbot in regina to see if i cant find any more like minded people out there.

i am trying to see if i cant arrange a meet up with all the reprap people here in SK some time this dec, i hope i can do it. i would very much like to meet more people who are interested in this project so if you are in sk find me on the forums at reprap under canada and we can see what we can arrange.

i am getting a few more things done on my shead  whial i am waiting to get the money i need to order the parts for my repstap. i am still trying to figure out the best way to rebuild the part i need, i have a few ideas but i cant do much with them just yet, i need to find something or buy what i need, kinda wish i had the cash to just buy the frame and parts i need, but alas i dont, i will figure out something soon i hope...

but here are some fresh pics of my shed for now.

i got most of the one desk down now, and the shelf is down now too. i am also getting my wiring in now too, so that is nice to see, my breaker box is going to be to the right of the window.

i have more insulation in the roof now. i thought i was going to need 3 more for the roof but i was off and i will just need 2 of the 3 i ordered, so that will save me a little money.

more of the roof and the corner of the wall are done, tomorrow i will get the vapor barrier finished in the corner, and get the measurements i need so i can get the lumber yard to cut the plywood for me. 

any one have any idea on what to do with an old cabletron router, wonder if i can hack anything else into it.

hmm design flaws

i got my pulleys and everyting i ordered this time around, but i discovered i have an issue with my threaded rod, and belt, i think one of them is bent, and that when i have the pully on them they are all very hard to turn at the same time. so i have decided to try to remake my Z axis. i know it is not the time in my build that i want to do that,
i dont think that belt is going to work too well it was a pain to get it on there. and no place to attach the stepper to it has well.

I have been thinking  about the best way to do it do i do it with a cantilever type of over hang like this
this is one way i thinking about doing it.

this is the other way i am thinking about doing with the 4 threaded rods, i was just too lazy to re build the platform to look right for this one right now.
i do like this idea a little more but i will have to see what i can build, right about now, i am just kinda wishing that i had the funds to just buy a kit and just be done with it but money is too tight for that right now. after xmas maybe. i will see. but i will be ordering a new operators super pack from maker gear with this next paycheck, i just dont have all the tools i need to make what i want just yet. but i can do it once i get printing  then i can mod to my hearts content.

but for now i just need to do what i can and with what i can, so let me know if any one out there has any good ideas. or tips,
