Print issue
Background: I have been printing on my mk3s+ for years now with a wide range of materials from TPU to ABS to PETG. The problem just started to randomly occur when printing PLA. I have printed PLA with no issues before and now all of a sudden I cannot seem to get it to print. I am using and have always used the default settings with 0.2 layer height Quality SPEED for PLA. I have tried troubleshooting it for hours with no success.
Problem: rough surface layers after the first layer (higher speed and flow rate). Please see the image.
Potential causes:
- Under/over extrusion?
Ran cold pull and cleaned nozzle for potential clogging issues. Adjusted Z offset to where the first layer was near perfect.
- Is the extruder gear too tight or loose?
Inspected, adjusted, and cleaned the extruder gear with no success.
- Is XYZ not properly calibrated? Z offset?
Readjusted PINDA and re-ran XYZ calibration through Prusa.
I did not troubleshoot the printer settings because I was able to print PLA perfectly a week or so ago.
Please, any help would be appreciated.
RE: Print issue
The only thing I can think of, is that there is an issue on one of the axis (so only X-direction or Y-direction, depending on the placement of the print). This assuming the image has the same placement/orientation as the machine, it looks that the printer is fine in X-direction and wobbly in the Y direction. If my assumption on placement/orientation is correct, you can easily check this buy rotating the object 90 degrees in the slicer.
