OK, here's the print. It's stitched together from two scans, so do excuse the seam in the middle. 

As far as I can see, the only issue is on the left edge and it's the same along the entire edge. 

Sorry about the squished image. Looks fine in the preview.

It doesn't look like anything to me.

That pattern changed my mind.  The infill is not being distorted while the perimeters are.  A logical boundary issue.  The move points are being made and the end point is clipped as it builds to gcode. 

Could be printer, could be Plicer.  There was a recent issue similar - turned out to be a manually input offset somewhere.  In that case the printer was clearly clipping, but the parts didn't have infill, so might be the same thing. 

But check your Plicer for table size, origin and extruder offsets, and check the offset values in the firmware.

Mystery solved. The print is simply going outside allowed print area. Marlin is scaling the x motion to keep things inside legal bounds.

There is even a warning in PrusaSlicer when you slice the file.

Guy - when you pulled in the 3mf that gave the error - what did your Plicer say for Printer Profile?  Here, it just said "System Presets" and not a profile in the file David uploaded.  And I sliced without error.

Looks to me like the whole pattern is shifted about 1-2 mm to the left - squished on the left and inset from the edge on the right

RE: Prints getting squished at the left edge of the print bed

IIRC, the first time I opened the file, I simply clicked on slice and it out came the gcode. Only hitch was it printed with PLA settings with my machine loaded with PETG, but my bad. None the less, the print showed the left geometry distortion.

My next opening included an attempt to move the leftmost piece rightward only to be faced with all four pieces being linked together. That's when I noticed the error and blue colored objects. Reopened and found just a 1 mm nudge was already too much. That is when I was certain of it being a limits issue, not hardware.

OK, guys, I'm 100% with you on it being a software issue. I printed this overnight (model attached). 

Look how the pyramids are normal up to the point where they're cut off, but are pushed in all the way back in the places where they would have gone beyond that point. That can't be hardware, right?

I haven't touched printer setting in the slicer at all, should be all defaults. 

Is this right? Should X be -1.64? 

Is it possible the zip tie messed up my XYZ calibration and the error persisted in software? Should I run it again now that the fault has been cleared?

OK, rerunning XYZ calibration did fix the issue. Now my 0,0 is at 0.36,0.13.

Thanks everyone for help. I hope the issue wasn't too dumb.

P.S.: Should I match my origin position in Plicer?

Me, too. My print of a 246mm wide object is squished at the left edge. What is the solution?
