It's not you - it's the printer! The M3D Micro is not a very sturdy setup. The X-axis is a single pair of thin rods, hung up on a pair of similarly thin rods in Y and mounted on 3 very thin pillars in Z. While the idea is good, the execution is not particularly well: The rods are too thin and the design is virtually unchanged since 2015 and thus this review ...

Layer shifting has two basic causes: the partially printed part moves or flexes, or the bed or Y carriage (almost always -- they seem rather uncommon on the X axis) skips one or more steps in one direction or the other. Permanent layer shifts -- that is, where the entire print above the shift is and remains shifted -- are more likely to be the latter; ...

Layer shifting can be caused by a number of different things. The following list of solutions is from All3DP's article "Troubleshooting Common 3D Printing Problems" under the heading Print Offset in Some Places: CHECK THE PRINTER HAS A STABLE BASE Place the printer on a stable base and in a location where it will avoid being knocked, poked and ...

Fixed it finally, seems that the X axis was not level. Thank you to everyone who commented.

Long story short: Try to replace the stock power supply. We connected UPS between the printer supply and the wall outlet and the skips reduced to one/two per print. We replaced the supply with random old used Mean Well SP-320 (zero care about the power panic feature, just plain 24V connected) and voilà: reference design passed. Also few more complex designs ...

These are (at least almost certainly) not layer shifts. A layer shift is when the physical toolhead position becomes inconsistent with the logical one because a stepper motor missed a step or the bed surface shifted or something else went wrong. It's possible for them to reverse if the same happens in the opposite direction at a later layer, but very ...

Zeiss Ikon's answer is good - but just in case that doesn't solve it, have you printed larger / longer prints before? There's a well known problem with the Ender 3's 4.2.2 motherboard that causes layer shifts as it overheats on longer prints. You can try elevating the printer and putting a fan underneath to see if that changes anything. (I had that problem ...

That's a retraction issue, not layer shift. Your nozzle starts printing a new line in those areas but doesn't extrude enough plastic at the first moments, resulting in a weak line.

This is varying underextrusion due to loss of material to oozing in the interior of the model. When printing the infill pattern, the nozzle doesn't follow a single continuous extrusion path, but moves from the end of one path to the beginning of the next, and under Cura defaults, does this without retracting the filament. This causes unpredictable amounts to ...

SOLUTION Unscrewing the mainboard enclosure and tilting it to allow better airflow like in the picture shown below. This is the same issue as many others. https://forums.creality3dofficial.com/community/ender-3-v2/layer-shift-ender-3-v2/ https://www.reddit.com/r/ender3v2/comments/kn8u72/layer_shift_investigation_data_and_video/ I appreciate the assistance.

You mentioned a noticeable 'clunk' when it shifts, are you sure it isn't a physical obstruction? You said you checked that all axis run smoothly but are you sure you checked the full extents of the printable area? Watch carefully when the issue happens, are any of the cables getting snagged on the machine or surrounding workspace? Check under the bed in ...

This is classic Layer Shift in the Y plane. This happens in one of three cases: Belt too loose Belt too tight Bed movement hindered The belt should ring and resonate when tapped, giving a nice tune. I haven't really tuned mines, but my ender3 (250 mm bed movement in total) has about a G major. The bed movement should be, with motors off, easy and smooth. ...

Buried in a bug tracker entry for a seemingly unrelated issue, I found what seems to be the solution: @johanmga, I've discovered the velocity jumps here come from using "classic jerk" computations, and happen whether or not s-curve acceleration is enabled. Try uncommenting //#define JUNCTION_DEVIATION in Configuration_adv.h; that will disable classic ...

While I first experienced layer shifts a couple times before upgrading, only while using extreme acceleration settings (3000 mm/s² is fairly extreme for moving the bed), their regular occurrance, which is near-constant with some files, seems to have started after I upgraded the firmware to Marlin 1.1.9. Reverting to the manufacturer's firmware, with no ...
