Is there any possibility I might be experiencing z wobble? If so, what fixes apply to Solidoodle 4. I never had this problem with my previous SD3

Go pick up a 5/16-18 wellnut, lube it up, and put it on the rod such that it is flush with the top of the Z platform. this worked well for me

Apologies for delay; still in trouble? Might be a tricky one, maybe a bit more info will help round it down?

Hmm. Very even pitch on that waviness - what layer height is that at? Can you measure the pitch of the waves with a ruler (measure 10 peaks distance and divide, for example), that might give a clue.

I assume the print is prismatic (same section all the way up), so the wave pitch could be in either time or z axis. Can you try something like 30mm cylinder with a 20mm cylinder stuck on top (e.g. attached) and see what happens? If the waves are the same on both cylinders then it's a z problem, if the pitch changes it's a time (probably temp or extruder) problem).

In the interim:

* What does your temperature graph look like (bed and extruder) - are they dead flat or do they have waves?

* Did you tune your motors as part of calibration? Does your extruder stepper driver (square black chip on the motherboard closest to the extruder motor plug) get hot?

Thank you for the help grob,

I did calibrate the belts but haven't gotten to tune the motors.

The waves do seem to be prismatic and my temperature chart is dead flat for both extruder and bed.

Will soon print the cylinders to be able to know if it could be an y or z problem. Thank you.
