Adjust your X and Y motor pots on your board. This happens when your motors are pulsing from the lack of current, giving you the “moire” effect. *edit* Down voted for no reason. Guess I won’t give any advice here anymore
Have you adjusted the nozzle temp? I’ve been able to fix a lot of my issues like this just by raising the print temp up. Just out of curiosity, is that ABS?
The issue seems to appear along the outline of extrusion, there is no retraction at each 5mm of the outline, i think.
I would first check the extruder and make sure it is snug.
raising the temp make is even more pronounced. The part was printed in PLA but this also happens with ABS. The only filament it doesn’t happen with is ninjaFlex. I believe that is so because of the unique way ninjaFlex behave while its being extruded, in that the it creates a little pressure as its being melted and then extruded
I didn’t want to have to buy stepper drivers, but i might have to
I have done all of the things you mentioned. I will recheck the tightness of the printer. Honestly i think its a micro stepping issue, but i really don’t know much about it and haven’t been able to find much info through google searches
I wish it was that simple. I have already made sure the bed is level and properly calibrated.
Thanks!!!
This was a calibration print. I set a print speed of 40 mm/s but it slows down to about 10 mm/s if the layer print time is below 30 sec. Also I can adjust the extrusion percentage lower but the i have a problem where the walls would be to thin and not printed at the desired thickness. I will keep trying
Thanks for you suggestions
it is a smooth rotation then its stops for a fraction of a sec. I don’t think i have noticed it jump.
Layer height is .25, .4 nozzle, 1.75mm filament, at 40 mm/s print speed(Slowed down to 10 mm/s if layer print time is under 60 sec), heatbed at 60 c, and hotend at 220 c (I use a B3 Pico and due to the design it has to run a bit hotter or else it jets jammed)
This object was PLA but also happens with ABS. Also i have used ninjaFlex and it prints out perfectly. I believe it does so becuse of the unique way ninjaFlex prints out and creates a small pressure in the melting chamber so it doen’t matter if the motor start and stops, as long as the delay is not to long.
Honestly I believe it might be a micro stepping issue in the Marlin Firmware but I have had a difficult time finding and info doing google searches.
Thanks!!!
This was my first instinct.
I read it and took you suggestion into account
.
Correct. No retraction in the making of this print
Extruder is nice and tight
I have moved the stepper pots both ways with no success and. PID autotune has been performed on the hotend
Thanks
What kind of machine is it?
Swap your extruder driver with another axis driver. Readjust pots. If ok, swap out your extruder. If you still have problem then your extruder is fine and pots fine.
What type of control board You could always swap stepper drivers from another axis to see if it changes anything
Switch the e and z before buying and see if it helps. E is most used and z is least used. If it resolves then you know before making any purchases.
