Did you check if the scaling is ok?
You have to set the scaling correctly, after you can test the velocity and acceleration . If you have the Z axis move to fast or not move at all, check the proma thc thread on this forum on how to fix that.

Nice.
What exactly is the low speed in your case? 800 what? mm/s?
If you are getting joint errors at higher speeds, check the acceleration, it should be 200 to 750 mm/s/s for a plasma cutter.

When you are talking about being slow is that when jogging or when running gcode?

When jogging, speed is determined by
Code:
[DISPLAY] DEFAULT_LINEAR_VELOCITY = 120

and set in machine units per second
