hello! it is currently 1/10/2020 and i figured id post an update. the frame is almost finished (see below pictures), and i figure that if anyone here has any input on things i could improve, i should update this thread.

Here are some pictures:

finally, here are all 84 pictures I've taken for more detail: https://postimg.cc/gallery/1dk25jk0c/


changes to the cad are the x/y axis are now 12mm "rectangle style" linear rails. they will use 12mm belts.

the z-axis is driven by ball-screws. should i drive the set via one motor for the two, or give each one an individual motor?

the pictures don't do this justice, to work on this i was able to sit down INSIDE the printer! the build area is roughphly 500x500x900 (it will be a bit bigger than that, but this is the initial idea)

does anyone have experience ordering custom KEENOVO heatpads? if anyone has questions/comments/suggestions feel free to post. ill post again in a few months with another update regardless.

EDIT: it is powered by four sola PSUs, 2x 2.5 amp (one for plc, other for safety/lights/contactors), and 2x 10 amp ones in parallel for the duet. Sola are really "the best of the best" (within reason), so i went with them. the computer psu is to power the pc that interfaces to the duet (didnt want to use a paneldue, wanted webcam etc functions, since the door wont be clear). the system is 24vdc. i know my diagram sucks, but its the best i can do with the software i have (microsoft publisher). hope this clarifies.
