I have a problem with bigtreetech skr v1.3. Im using it’s pins for external drivers(TB6600) i have checked all the connections between the motors and the drive i have tested them even with an arduino uno board and the are working. I have changed the Configuration.h - The serial ports the mother board name and so on.
platformio.ini - i’ve set the default-envs to LPC1768
Configuration_adv.h - i’ve chenged the drivera to TB6600.
When i plug the usb type B to my PC open up pronterface hit connect and it connects after witch i choose the options for xyz motor test by clicking 100mm on xyz each but they don’t move at all.
If prontaface says it has connected then the problem is not comms, which means your wiring is the most likely suspect. I did a quick search and found this https://www.youtube.com/watch?v=uo_auXbhpJI It is a terrible video but might point you in the right direction. I suspect the bit about setting the board for full steps and not microsteps is where you may have gone wrong.
