My cnc was working with the tb 6600. I have an axbb-e and use uccnc.
Replaced the tb6600 with the 556s I get motor lock but no motion, uccnc behaves as if it were in demo mode but its not in demo mode. Checked license and my name is there. The numbers move up and down but stepper motors are silent not budging.
So what I've done so far.
1. I've unplugged the 556t's and put back 2 x tb6600's on x and z, nothing happening. Same deal numbers are working stepper motors lock but no motion. (which in itself is annoying as it was working with the tb6600's before the transplant)
2. Check and rechecked the wiring many times.
3. uninstalled and reinstalled uccnc.
4. reset axbb-e to factory defaults. The two green led's and blue in the middle both working.
5. checked power supplies both working.
6, power must be reaching stepper motors as they lock and cant move x or z manually.
7. got to a point where I was just staring blankly at the box scratching my head.
If anyone has any ideas or hail mary's I'd appreciate any advice.
Many thanks in advance.
Steve
