Hello people,

I have win 7 32 bit with tb6600 board and nema 24.
I have a problem when I slave A to Y, one of the motors run ok and smoothly but the ather motor run slowly with intermittent steps!
I have changed the motors but its still one of them moving bad!
I have tried to change my kernal speed and sometimes its going ok but when restart my Mach3, again the problem appear!! I didn't know what to do! Can someone please help me?

Thanks so much!

can you post your XML file for your profile.

What voltage are you suppling the TB6600 boards with?

What pulsewidth do you have set?  CONFIG >> MOTOR TUNING

What steps / mm [or inch] do you have set ?

What maximum velocity mm [or inch] per miniute do you have set?

What maximum acceleration mm [ or inch] / s / s do you have set?

What kernal speed do you have set (25khz seems to most of the time prove to be adequate for most settings for stepper motors)
