G0 commands work as expected.

Seems my problem is with the Jogging.

X axis jogs ok.

Y axis

When set with 400 unit/min velocity and 2 unit/min acceleration will job at almost 1600 unit/min
When I change the acceleration to 5 it will jog at clost to 800 unit/min.
When I change the acceleration to 10 or higher, it will job at 400 unit/min.

General Mach Discussion / Motor Turning Errors

« on: March 08, 2018, 04:44:18 PM »

I have my X and Y axis both set to 400 ipm speed with an acceleration of 5. 

My X axis is ~2200 steps / inch
My Y axis is ~ 560 steps / inch

The motor turning chart for these two is very different, although they set for the same velocity and acceleration and only differ with the number of steps per inch.

When I run them, the Y runs faster and accelerates faster the the X.

Also I've noticed, if I jog the Y axis, then quickly jog the X axis, the X axis will run almost 4x faster.

Why would the steps per inch (which is correct) change the velocity and acceleration of the axis?

Is this a bug in the system?

When I make a change to the velocity or acceleration in the motor turning section I feels like nothing changed.  I hit the save axis before changing axis or exiting, and the changes are there when I open the screen again.

Anyone else see these problems?
