Step1 stepper drive board from Conqueror Design

Hi Dave

I'm assuming the board has a L297 driving the two L298 ICs
they must of connected the two H bridges inside the L298N in parallel to make a higher current bridge

until CDE are back in business a faulty PIC is a problem
unless your lucky and the PIC program is not protected so you can copy a working PIC - a bit of a long shot I know


for now I would swap the faulty drive with a working drive to prove the driver is the problem and not the control board
changing the switch settings that determines which axis commands the board responds to may be enough instead of physically moving the board – just avoid jogging into an end stop

with a logic probe you monitor the L297 direction pin to see if its the PIC or L297
