Hi All.
My new machine is up and running, but there's a few niggles :-(
When I hit GOTO ZERO in Mach3 the steppers on X and Y scream and although there's some movement, the spindle does not move to the correct position.
Z-axis behaves correctly.
Motor tuning (as per manufacturer) as follows:
Steps per: 320
Velocity: 4000
Accel: 300
Step Pulse: 0
Dir Pulse: 0
If I jog the X/Y axis using computer arrow keys, the unit moves smoothly and without problems at 4000mm per minute.
When I use "Ref All Home" function, it also moves smoothly and without problems.
When I change the Velocity down to 1000 things get "slightly" better.
The unit does move back to zero position, but it does it in a pulsing movement in stead of a smooth movement.
But this does not really solve the problem, as everything is very slow like this.
With some experimenting I found some other interesting behaviour as well:
When I execute this command
G0 X0 Y0
Same problem: screaming steppers, pulsing movement.
But if I execute this:
M03 S15000
G0 X0 Y0
the machine works perfectly fine (smooth movement). I dont understand why turning the spindle on makes the G0 command work differently.
I'm new to Mach3 and GCode, so I have no idea if this is normal behaviour, the CNC machine or Mach3 being the problem.
Any insights will be greatly appreciated.
