@Phaedrux Thank you. I'll give this a try when I get a free moment.

Veti, I'm using a tool changer all tools are offset from the Z probe that does mesh level and initial homing without any tools attached to it.

I've spent the last month trying to figure out why my first layers are so bad and am at my wits end, hopefully someone here can help get me back on track.

Printer Jubilee CoreXY with 3 print heads and magnetic bed, Duet2 WiFi and Duex5. Config.g and all other files are pretty much straight from the Jubilee GitHub that others have been using without issue. Any variation between my config.g and the original is from my trying to get mesh compensation to work.

I've ran mesh more times than I care to count and with the thick Buildtak sheet meshes are consistent as shown in the picture below and with the exception of the dimples from magnets in the heatbed I would guess to be acceptable. images of the large square are as good as I can get without causing ripples from being too close to the bed in spots so I really can't lower the nozzle any more without causing issues. See picture of small gray rectangle for an idea of what I get when I bring the nozzle closer to the bed.

Lead screws are turning during prints so mesh is trying to do something. Having mesh enabled yields slightly better first layers but not by much.
Tool offsets were generated using TAMV (tool alignment using machine vision).
I have three Bondtech print heads on the machine and results are almost identical using any of the three tools.
All three tools are firmly attached to the carriage when picked up.
I've increased and decreased Z jerk, acceleration and speed in every combination I could think of and found that l get the best results using the following setup in Prusaslicer, Z feedrate: 400mm/s, Z acceleration: 150mm/s^2, Z jerk: 0.4mm/s and 25mm/s first layer speed.

Currently I'm running RRF 3.3 B1 but have worked my way from 3.1.1 up to it and even performed a wipe of the Duet 2 WiFi and reinstalled using "Fallback Procedure #3" to reinstall RRF 3.1.1 with no luck.

Any input/pointing out of a stupid mistake on my part that would help me get better first layers is greatly appreciated.

I'm having similar issues and would like to see something like this as well. Duet2 WiFi also. To say I'm unhappy with first layers is an understatement.
