Yet another layershift problem... - Hardware, firmware and software help

By the look of it it crashed into the poorly printed surround of the hole on the left. You might have a point of poor adhesion on the plate beneath this or a draft might have messed with the cooling from that quarter. You might benefit from expanding the infill/perimeters overlap (expert mode) but it may create more problems than it fixes.

Cheerio,

Please show us the underside of that failed print.
Cheerio,

Im afraid I threw it in the garbage bag I brought out yesterday. But this is not an interrogation. You will just have to simply believe me. I am not new in this game of 3D printers. The thud-sound it made sounded more like/very similar to a machine boundary/end point thud rather than a collision-with-print thud.

Trying to print a plate 150x70x6mm.
That size, and the thud, make warping the first suspect.
Pictures or part files would greatly help with diagnosis.
Cheerio,

No warp. Like I said, it happened on the model between 2 holes on either side.
I thought I had attached the project file. Guess it didn't work.

I just simply reprinted and the print was successful. Which suggest there was something with software/firmware.

Trying to print a plate 150x70x6mm.

The layershift happened at layer 6. On the first layer without solid infill.

I have unticked "avoid crossing perimeters" and set "ensure shell thickness" to "disabled".

I heard the printer make a "thud" sound, like it was moving really fast and came to a sudden stop mid movement. The motor(s) didn't squeal this time.

Went to check it, and yes, layershift.

If anyone wants to investigate I will attach the project file.

Hardware-wise I checked belt tension, it's what I'd say is okay. Unlike first time around when "ensure shell thickness" was causing a layershift the belts stayed relatively in tune. From 92/98 to 91/100. Which I believe can be caused by something stupid like ambient temp.

Anyway. Before try no.2 I adjusted them back to 92/98.

Since Im having problems uploading a picture here I will simply explain. The layershift happened like I said at layer 6. It successfully did the perimeters around the right hole but the left hole was put down x, +8.80 y, +8.80 mm wrong. So whatever happened, happened between the holes. And the only thing I can suspect there is the wiping procedure. Unless a poltergeist put his curious finger in the belt.
