Topic: Calibrated Everything Now Z Wobble?

Okay I Calibrated My Extruder, Leveled my Bed, and Made Sure the Z-Offset and Extrusion Multiplier is just right so my extrusion width matches what it should be in the program. Also I am Having No Problems with Sticking and Warping.

But Now after all this I believe I am getting Z wobble. It may not be Z wobble, any Opinions?

Below is a Die From Thingiverse Printed at .2mm.

I just don't understand how I am getting the wobble now and I didn't get it before. Could it be Something in the Firmware?

If you were not overextruding before and prints looked better.... well I would say that you are overextruding now even though you have set the extrusion width... overextrusion will make Z varying height changes (Z wobble) more pronounced.

Do you have pics of your before prints? how about screenshots of your settings pages for RH and Slicer?

The Cube on the left is printed at .3mm, The Red Cylinder I printed on the Kapton Bed with the Solidoodle Filament at .2mm, the white one is with Octave Filament at .2 on a glass bed with painters tape which is the Best one so far with me changing settings. The completed die is the one from earlier and the half complete is after I changed settings that I thought would improve it. I find it odd that the circle has less wobble than the square at the same settings.

Below are my current settings. NOTE: I did calibrate my extruder with the 100mm to 100mm calibration.

Can un-even tightness in the y carriage belts cause the banding? My left belt was a lot tighter then my right belt.

Since your banding is even around the objects I doubt it is that, I notice you have nozzle diameter set to .35mm... how long have you had your SD? they switched nozzle sizes up to .40mm a few months ago.

Also I see you have the filament diameter set to 1.75, is yours actually around 1.75? most of the stuff I use lately seems to be undersized a bit.

Mine is brand new, just got it the other week. The only reason the .35 was in there was because I watched a calibration video on youtube and they said to use .35mm. I doubt that is really the issue though, I will change it and try again. And my filament varies from 1.74-1.76mm so I put 1.75 in the program.

Re: Calibrated Everything Now Z Wobble?

Just something simple to check.

Being that your printer is relatively new,what you perceive as Z wobble may be that the three "bed leveling screws" have backed out during shipping and the bed itself is wobbling.

It has happened,you should have around 1/4 in sticking out below the nut on the base frame.
