Problem description
When I run the attached GCODE, a repeatable error occurs - the machine sems to lose steps on the x-axis and so a part is shifted to the left.The preview of the part in LaserWeb:
And this is how it turned out:
An arch was shifted to the left. However, I was in the room throughout the job and didn’t hear the stepper motors struggling or skipping steps. Hence it seems to me to be a software issue. Unfortunately after aborting the job, I didn’t take note of the displayed position of the laser head.
I have attached the GCODE below but it seems fine since NC Viewer displays the job correctly:

System description
-
My machine is a CO2 Laser
-
I have a RAMPS1.4_SF
-
It has Marlin version 2.0.x installed
-
I connect via USB
-
My computer(s) on which I run LaserWeb run(s) Raspberry Pi 3B on Jessie (as per the RPi setup instructions). The Pi also runs an instance of Motion for remote webcam monitoring.
Here is my configuration:

I’ve tried rebooting the Raspberry Pi as well as the frontend of LaserWeb. Next, I’ll try re-generating the GCODE after re-ordering the cut paths and if that fails I’ll disable motion and try again. However, I was hoping for a more long-term fix to this. My prime suspect is Motion as I’ve heard it’s resource heavy on the Pi.
Has anyone experienced similar problems before? Would be most appreciative of any advice!
Cheers,
Ethan
