I bought my leapfrog roughly a year ago and had been content with it until recently. Horizontal ribs (4-5mm wide, fraction of a mm high, almost like waves) started appearing on the prints, many times ruining the results if I couldn't grind or sand them away.
The example below was generated in Cura with the following settings:
M201 X1000 Y1000 Z50 E250
M204 S2000.00 T2000.00
M205 S0.00 T0.00 B20000 X15.00 Z0.40 E15.00
-Everything else is factory default, if my memory serves me well. Has anybody experienced anything like this? Read through quite a few forum topics all over the net but couldn't find a proper solution.
Thanks in advance!
Try using randomized starting points, if your slicer has that option.
This is just a pattern caused by the extruder.
Hmm I remember there being a setting called spiralize which continues the same extrusion width straight up but is only used for hollow objects.
Try reducing the extrusion multiplier because, on the corners, there is a noticeable over-extrusion. As well, if you're printing with PLA, make sure your fan is working.
I usually dont go below 0.9 on the multiplier, a small change matters.
Other things you can try:
-Different manufacturer of filament (make sure its the diameter)
I once had a filament that was hollow and didnt notice and this made blotchy prints.
Bad quality filaments can vary in diameter as well.
-Changing the Steps per E of the extruder.
This is basically adjusting how much the extruder turns.
The pattern that you are seeing I think is an XY resonance, run the appropriate file below. As to the cause you could have changed the platform the printer is sitting on, an x or y motor is not running as smoothly at the speed you are running. There are also inputs in some hosts to specify a resonance for your machine and compensate for it when generating the g code. It is not something I have played with in depth but it might be useful for you.
