eBay TB6560 Stepper Motor Driver Boards

5 is a good figure to start at.
Not familiar with that board but can you jumper the charge pump off, if it has one. Some computerers can hickup on charge pumps depending if they buffer the charge pump signal.

Awsome feedback, thanks Gents.

Where I'm at at the moment. Just set up my gear on a second PC to do a quick check.
Good results, all working at the same speed now, so proved a BIOS or hardware problem on my CNC PC.
Will check the BIOS config on this, my home internet PC, which has the TB6560 board pluged in, and compare it to my CNC PC.
Will post details of the BIOS settings to help others that may encounter this problem.


I do have some minor "graunching noises, or fits n spurts" on Z axis. Swapped over motors, motor OK, definately the channel.
I adjusted pulse width to 5 (which was maximum) in config/motor tunning/Step pulse (0-5us), nil effect, still some minor graunching.
IS THAT THE PULSE WIDTH ADJUST YOU SEGESTED?

thanks
Rick

Yes that's the right pulse width setting you changed.

Have you tried experimenting with the max velocity values in that same config? If the motors will only manage 60% then set the value to 60% of what it is now - but experiment you might get more!
