Hey,
Thanks for all of the advice, sorry it has taken me a bit to respond as we have been dealing with a sick child and everything had to go on back burner for a few days. I will post config.g in the morning as soon as I get off work. I have the current turned up to stepper rated current and ptfe lube on the screws and linear rods. It all moves fairly effortlessly. I dropped speed way down for Z and did a side to side level at screws. Takes 6x before bed is even both sides and im ok with that. I then home it and do it again and it shows z axis off by .8mm again. Hopefully this is making sence lol. Also I am using the 0.9°, 180°C high temp stepper motors since this printer will be doing alot of PC and Nylon in a enclosure. Also wondering if the bltouch may be going bad, I have one of the ir sensors the dc designed that i got from filistruder so i may give that a shot also if its more acurate.

ok understandable, I am doing something similar but I am coming off a compressed air line from outside and using a pressure transducer to regulate pressure to the hotend, and print cooling. I am just waiting on the transducers to come in.

sounds like he wants to control servo position based on fan speed. what about hooking servo up to a external control ,like what came with the berd air, controled by the pwm fan pins you could use a bec to feed the controler for the servo voltage
just a thought

thank you I will adjust as instructed, Thank you for helping me with this. I did have it set to a corner but in my start gcode what I did was have it heat the bed and nozzle then do a G30 at the center just before it starts printing I will change that. Thanks again for your time. It is very much appreciated.

funny thing I have 3.1.1.zip on the sd card lol I corgot to upload it when i reflashed the image.

just calling that macro,
I cant reach to the full 400 on bed due to the mounts for the linear rails hence why i am using X20380
I thought it was the newest firmware on there but ill go ahead and upload 3.1.1 This may be because I had the original sd card get corrupted and had to redo disk image on it.
M350 could that be because I turned off microstepping on that? I was told it didnt need it since it was the extruder. Its actually still really quiet lol
sorry for not including the home z I must have accidently double clicked it.

this was after skew macro above and running a mesh compensation probe then checking skew againsame result even when i turn accell and jerk way down.

cant find anything hanging up on z axis either bed drops from z0 down to bottom when unplugged on its own. just to be sure i put a small amount of lithium grease on the rods and the screws but still same issue
