A project log for A4988 Stepper Driver Duplicator

Putting two steppers on a single driver is dumb. Four doubly so. Here's a stepper driver breakout.

Got the boards from Seeed yesterday, and soldered one up:

Assembly was easy. I was worried about soldering the SMD caps, but with the right tip it was simple enough.

Right now, this project is *done*, but I still need to test it. That's not going to happen until I have the Z motors in the Long D printer, and that won't happen until some weird flanged bearings show up in my mailbox.

I have 9 more of these boards. If you want one, drop me a line and I'll see what I can do. Otherwise, I'll just give them all away at next year's MRRF.

so? where did this go? I think this is a great idea. i've never created a PC board before. it would be good to see how this board unfolded. did it work? <-- that's pretty important. i believe it would, but for me, this would take a lot of time getting the circuit board(s) in my hands, and if it the circuit just did not work, then it would have then been a fool's errand.

but thanks for this. i will archive it, and when the time comes that i have the process of sending out boards to get built, i'll give it a try, then.
