Hi. Are the reprap and similar "motherboards" just electrical interfaces/breakout boards to connect to stepper-driver boards and other I/O ? I want to use heavier duty stepper motors for an adapted CNC router, so won't be using 4988 or similar.

I've soldered some small pcb's, which feed the STEP/DIR pins from the POLOLU-socket to the inputs of a common stepper driver with "beefy" NEMA36 motors]]> VDX General Fri, 19 Jun 2026 12:38:35 -0400 https://reprap.org/forum/read.php?1,897633,897633#msg-897633 https://reprap.org/forum/read.php?1,897633,897633#msg-897633 Are the reprap and similar "motherboards" just electrical interfaces/breakout boards to connect to stepper-driver boards and other I/O ?
