Hi...as per my knowledge the signal level on the expansion header is 3.3V whereas most external stepper drivers specify 5V. Nevertheless, most external stepper drivers work when driven direct from the expansion header.Did you use the M584 command to remap the appropriate axes or extruders to the external drivers?
You may also need to extent the step pulse timing, using the T parameter of the M569 commands that correspond to external drivers.

Hi,
I tried TB6600, and after many goes at getting them to work, I gave up and change to 6560's and they worked straight out of the box.

Is this GRBL related?

Hi guys, I am here to say a hugeeeeee Thanksssssss.
The code S1=255 saved my lafe, and fixed my loose stepers.
I have removed my Gshield trying to fix this problem, installed 4 cheap tb6600 to try to find the source of this problem, and this thread on this forum saved my life!

Thanks to you all that contributed!
