Stepper motor driver questions.
February 05, 2010 07:51AM
Hi I have some questions about Stepper motor driver:
Where can I get PCB for it, because makerbot store is OUT OF STOCK !
Where can I get 10K trimpot, mouser doesn't have one, and Digi-Kay says "Minimum quantity not met; see price break." it wants me to order minimum 50 of them, I don`t need 50 I need 1 maybe 2.
And the same story with A3982 it wants me to buy 31 of them for $1,945.19 !!!

I'm using A4983 breakout board from pololu. Note that you must add a heatsink to this board if you get some, see my latest blog post

Ok I found the board and alternative for 10K trimpot.
But A3982 is big problem, all other distributors are out of stock.
