Hi

Many thanks for coming back.


I have 1629.84 set and the object seems to print the correct height. It doesn't bind anywhere up the z axis or wobble.
I spent some time upgrading to the latest Marlin Bugfix 2.0 yesterday to no effect. I even changed PSU to a spare 24v 360W.

Tried printing in 0.3 and 0.2mm, the 0.2mm has ridges at around 3mm spacing except for the top.

For Reference I am using Mattercontrol, PLA

I am next going to try printing from another app and slicer and try and see if it is the firmware.

I have been using the T8-2 single start lead screw now for 2 year on both my machines.

I have recently flashed the 2.06 marlin firmware, the funny thing is that when I print "Flexi Turtle Ear Saver" one machine works the other does not.

I may have to adjust my firmware.

#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 1600, 94.4962144 }

Could you post you model, would like to try you model.

How does your model not print correctly?

The Hinges stick on my 12v machine while they work perfectly on my 24v machine.

I can switch the filament between the two machines still the 12V printer does not like the Turtle Ear Saver

I need to test again with 3D Printing more Fail Proof Fidget Cubes.
