Re: Chinese CNC stepper motor stalling
Since "canman" is in my local area, I'm headed over tomorrow to troubleshoot. Normally I would ask the customer to send me really high resolution pictures so I can check the wiring and build, and then to return the kits for repair. I always do a repair for free after finding the issue. If they fry them again, the replacement chips are only $10. And it's rare that something actually fries the chips, but if this case, we eliminated most other possibilities... we can most more after troubleshooting tomorrow.
