Best practice procedure questions regarding hot & cold mesh profiles for minimizing failures.
Excuse my ignorance but coming from Prusa's this is all new to me and I have a million questions. My primary objective is to minimize the .100-200 microns gantry bow which I believe can knock off objects from the bed after 2-3hrs into a print even with the lid off my 2.0 with PLA temps. I believe this also increases the probability of layer shifts
- Should create and load a "hot" profile when the bed is hot?
- If so, how long do I leave it to soak? - What will the profile do to the first layer? Will it be a bit extra squished presumably? - Are there any handy macro's that I can somehow run prior to a print to heat soak? Should I even bother doing that? - I have identified the commands to save and load a particular profile but will they be overwritten with the bed mesh procedure that's seems to run prior to every print? - Is there any RATOS documentation on how to change the default 7x7 to something like 9x9? I tried adding something that seemed appropriate in user overrides, but it was simply ignored I believe.

Use PAM so it only meshes the print area. Then it is quick enough to do before every print
The mesh before the print indeed overrides the mesh, so the saved mesh doesn't matter much
Meshing just before printing will best reflect the situation for the first layer at that time

What's the point in saving a mesh then buddy if they always get overridden?
If you don't mesh before every print then saving has a purpose, and it is active during prime blob. But yeah mostly for checking the bed/frame otherwise.
Try PAM, it is so quick, it doesn't hurt to mesh before every time if your mesh is only 9 points for a small print.

Silly question, how do you disable mesh before every print? Is it in start gcode? I'm not at home currently otherwise I would check
It's a ratos variable
But don't

Clearly I have done something wrong installed PAM modified the start gcode and its still performing an entire mesh 😦
My bad I left the old code in there also
OK now PAM simply hangs on "10:49 AM
echo: Priming nozzle with prime blob..
10:48 AM
echo: Heating Extruder..." 😦
Was being impatient lol 🙂
