Motor Tuning with 2 motors on X Axis
« on: October 04, 2017, 03:42:42 PM »
Hi, I am about to power up my CNC build and I have 2 motors on the "X" axis which will run 1 CCW and 1 CW how do I setup the motor travel and tuning, I presume I disconnect a motor and do one then set "A" the same values, can anyone advise.

Many thanks John

Hi,
yes the 'steps per', velocity and accel must all be the same. You can cause a motor to run in opposite direction
by swapping ONE winding OR reversing the Dir pin (active low vs active high).

Or checking the "Reverse" box in Config > Homing/Limits.

I thought as much I suppose once I have say "X" motor tuned and then connect "A" as the slave then insert the same numbers in that drives tuning, then once I have 2 motors connected splits the load so it would be trial and error to change the velocity,acceleration  to the optimum , and then make sure both axis have the same steps per inch, Velocity and acceleration.
