Hi John,

Welcome.

Not sure they are all in logical order but the tutorials start here; https://www.machsupport.com/help-learning/

Your Gcode files ran correctly here without any sloping of the sides.

Interesting that you have the feed-rate set at 12,000 mm/min which an axis would not achieve over such a short distance as the zig-zag path. When I set the correct laser power for maximum velocity on the long strokes over-burn was created on the zig-zag. This results in pretty poor engraving results as can be seen in my pic. and it is really not the correct way to laser engrave anything.

I think you need to create a better toolpath and run at a modest feed-rate and see what results you get then. Something else worth trying (and this may correct your sloping sides) is changing your Ports & Pins / Motor Outputs / Step Low Active to Active Low (tick) for the X, A and Y axis.

If you .zip and attach the zig-zag Gcode file that is causing you problems I will run it here to see if the problem persists. Also attach your <your profile>.xml file (Mach3 folder (typically Mach3Mill.xml)) then I can check your settings to see if anything there is causing an issue. You need to rename the .xml file to hardus.xml before it can be attached (all files / attachments posted to the forum need a unique name).

You settings seem quite modest so the only other thing that I can suggest is that you look for some sort of mechanical slippage on your X Axis drive chain.

What are your Velocity and Acceleration settings for each axis ?

My guess is that you are loosing steps - try reducing Velocity and Acceleration in motor tuning and save the changes.

In an earlier post I mentioned how FasterCNC started trading as DDream

this pic. (showing their own, in house, Pirate license usage) was taken from their current DDream EC300 and EC500 product manuals.
