#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

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..." 😦
