i have a few worries about the belt i ordered though, i think i may have measured wrong and got one that is 2 small. so i will have to wait and see. i kinda wish i knew someone who was local with a working reprap or makerbot would make my life allot less trouble.
i am trying to make a flow chart of how i think things should work for my slave processor but it has been slow going on that front, so maybe after work tomorrow, any one have any good sites for that.?
i am also getting a few more things done on my shed i have another batt of insulation in it now, its a start, but soon it will stay warmer at nights, so i can work on it later in the day. but soon i hope to have more insulation in it, and the more the better.
i got the idea at work to try some other stuff to hold together a the heated end, is it a gasket maker that says it is good to 500F so i may make a test heater with it to see how well it holds up to the nichrome wire.
but i hope to have it insulated in the next month or so, and i hope to have it mostly wired up here soon. but it will take until spring to get power to it. but its a start, and i am happy to see it.
i have not had much time to work on my coding yet. but i am trying still. but i am glad to see that i am starting to learn a little more.
i have been thinking a little more on how to add some optical encoders to my repstrap. i saw a post with some on some dell printers. it seems like a good idea to me if i can find them. but here is a forum thread that has a few of the ideas in it, kinda funny though has it started with a question about micro stepping on the pololu stepper drivers that i was using. forum thread
i am starting to work on my firmware, but i am noticing that is it far from my strong suit. but i am trying to do what i can. for not it is pretty basic, but i hope that soon i can learn how to fit what changes i need into the hydra mmm firmware.
well has of today most all of my electronics are done, just gotta get them all cleaned up and mounted.
once i get them all mounted i should have all that rats nest under control
i have my pwm driver and my thermistor circuit in this pic.
here i have the arduino mega, the board for my arduino nano, and the board for my stepper drivers. on this reincarnation i have added the ability to change the stepping on it. though i have more bug to work out with the power on it, nothing major yet,
with all of this, i just need one more stepper and some pullies, to get most of my repstrap working.
i also need to start working on my code for the nano, i will most likely be moding the hydra mmm firmware for this, but i really do have allot more to learn about programming than i did about the hardware.
i am starting to get all my pieces together now, i still need a few more small pieces
i hope to have them mounted to a board here soon. it will start to look a little different here soon but i am glad to see that all of it is coming together
in the picture i have my arduino mega, arduino nano, pwm driver on the left side, my thermistor reading circuit near the top, under my nano i have the board i made for my endstops and power distribution
i have decided to use a slave processor on my repstrap. i got an arduino nano from dfrobot so far i like it allot kinda wish it had a few more pwm outputs on it but so far i like it. i am hoping to use it to not only read the temps but to also control all my hot pieces,
here is the arduino nano, on the board that i made for it. on it i have the power inputs, thermistor inputs, led status outputs, 3 pwm outputs are moved to the edge for the heater controller. and the tx rx and grd brought to the edge for communication for arduino mega.
i decided to use 3 tricolor led's just because i had a few to spare, they are all on the same outputs. so they all turn the same colors at the same time. i am planning on using it to show the temps with the colors blue for cold, green for good, and red for too hot. i think this will be a good way to show the heat status at a quick glance. that is the idea any how.
this is the back of the board
but so far i do like the arduino nano its small and has the same cpu has its bigger brother.
but i am waiting on a few parts again, but i have a few more idea brewing still so i will post more soon.
well i was gone, up to key lake i got a few things i have been eagerly waiting on. like my dfrduino nano, and some more wire, and a pwm board from the fellow at http://ultimachine.com/ , i also got some more odd parts resistors and capacitors, but i am still waiting on my last order from seed, they normaly are not this slow, so i imagine costumes here in canada flagged it for some reason.
this is most of my order, i hope i can start to do some stuff with the parts i got here soon.
