I'm no programmer etc and muddle my way through. Chinese machine now running Mach3 USB / laptop Windows 10.
I only have 3 Files and they have run happily for a long time, which means you forget what you did when you set it up originally, so when something goes wrong, you are out at sea!
The problem started when the machine started to lose Y axis. Checked stepper motor and swapped with Z motor. Didn't fix it. etc.
Then I decided it was the Chinese copy of the Mach 3 that might be buggy so purchased a full separate Mach 3 licence...and that's when the problems really began. Up till now it was working fully but the new software required it to be configured from scratch.
First it turns out the fault itself wasn't Mach 3 at all. It had been worn slide bearing, which were were jamming! (Feeling a little dumb...)
Teplaced the bearings etc. Unfortunately now I do really have software / setup problems.
The machine has only to only cut concentric circles. Keeping things simple my zero / start point it the centre of the circle.
The new software doesn't appear to like the original files. It's throwing up G90/91 errors under "Abnormal Operation"
When checking the code it is always stopping at line 14 with another error code..and of course it won't run at all.
And finally the image on screen is no longer concentric circles but screwed circles.
I've been on another forum and they can't see anything wrong, which is as comforting as it is frustrating.

When the displayed image is correct, I get and "Abnormal Condition" flagged up. I changed IJ from Absolute to incremental. No joy. The displayed image now is no longer concentric...and the Abnormal Condition vanishes. To me that's all black magic.
I also get a main error msg that reads: "Radius to end of arc differs from radius to start line 14"
What am I doing wrong in setup? It's got to be a "you can't see the wood for the trees" situation.
Thanks for any thoughts.
