Ah true, do you think the influence of the bed heat stacks on top of the hotend heat or compounds it? I guess you guys got a good baseline though running cold bed prints.

Or maybe do two meshes. Idk anymore. Sounded right as I typed it out first lol.

Although that’s a different beast with IDEX. But of course everything is lol.

My thoughts would be to gradually revert back to the initial mesh so long as you heat soaked with your gantry a certain distance from the bed. I would think that after so many layers, the heat and influence on gantry bowing from the bed slowly diminishes.
So for instance you would heat soak at 15mm height then slowly interpolate the first layer “live” mesh over that distance. After 15mm you would be fully at the initial mesh.

Hmm, ok. I’ll let you guys keep at it. If there’s anything like gcode or what not you would like to throw at a separate machine just lmk what to do and I can try to add to the sample size by printing it out.

If it pinged the same spot of the initial mesh behind the nozzle but knows the nozzle position, could it could deduct the difference from the nozzle z height?

For sure but I feel like the beacon would still pick that up. Unless the gantry/tool head tilts forward or backward due to the bowing.

Hmm, figured it could ping at every point along the way then interpolate as it goes.

Or is this purely hotend stuff? I guess

Man, have not been able to keep up with you guys. Sorry if this is a dumb question or it’s been brought up before. But do you think it’s possible for the beacon to actively calibrate the mesh against its initial mesh? So that if it detects a large variation from the initial mesh it could adjust itself while the first layer is being printed. Or do you think that is impractical or not possible?

Do you let your extruder soak for this? I’ll print this this weekend. Got busy on some other stuff.

And yes I know 0.5mm is a bad start but I got my mesh below 0.2 while cold and that all went out the window after my first long (19hr) ASA print.

Yeah my mesh adds another ~0.5mm from cold (starts at ~0.5mm) to 110C so over 1mm total difference between my max and min at that temperature. Hot tightening at 120C put me at ~0.2mm max/min difference at both 80C and 90C. I should have tested at 85C as that would theoretically give me as close to 0mm as possible.
