Hi Marcin,
The controller you have is TB6560 based. Seems your problem is related step signal. Try the following:
- Activate E-Stop mode and check if all the motors are unlocking
- Set the kernel speed to 25KHz. Note: you must not use higher than 35K for this board.
- Save the config and exit mach3.
- Start Mach3, check if you can jog.
If problem exists then it is related to your board:
- Unplug the controller. Set the corrent setting to MAX.
- Plug the LPT interface and power cable.
- Carefully identify the PIN 3 of the main IC (under the heatsync) for any axis. Connect a volt meter at this pin.
- Jog from Mach3, you'll notice a variable volt...
