If you have an older HS3 Machine it may be necessary to update your printers config file to be compatible with the new print profile start gcodes. You can find instructions to update your config file manually here: Machine Errors After Profile Update |

Machine start behavior in this revision will be different from previous. The machine will now preheat the top plate to reach a temperature of 32°C before probing the bed which may take upwards of 10 minutes when ambient conditions are cold and it is the first print of the day. Additionally, the machine preheats to three different temperatures throughout the preprint procedure, which may include periodic pauses, please note this is normal operation. |
This update is released in tangent with new Pantheon Slicer Revision 2.6.1 https://pantheondesign.atlassian.net/wiki/spaces/docs/pages/76742657/Pantheon+Slicer#Install-PantheonSlicer-(2.6.1)

Previously, the nylon temperatures have slowly been pushed hotter and with more part cooling to chase higher volumetric speeds, but we have recently found issues with nozzle jamming due to filament burning when deposition rates slow down in certain parts of a print.
To improve restore reliability, we have reduced the volumetric flow rate from 20mm^3/s to 10mm^3/s, allowing us to drop print temperatures by 20°C. To maintain fast print speeds, acceleration is set high at 8000mm/s^2.

the machine will heat the bed and wait until the top plate has reached at least 32°C
the ideal probe temperature is at 210°C to minimize PEI damage, but these temps are too low for filament on a dirty nozzle to be squished out of the way as the material will be solid, so instead the machine will probe at above the glass transition melting point of the material (220°C for PETG, 240°C for nylon). These temperatures are set using the idle temperature box in the filament settings tab
after probing, the machine will then preheat to the actual print temperature before printing, but due to the elevated temperature, the hotend will expand downwards resulting in too low of a first layer height, a fixed, tuned offset is applied (+0.02mm for PETG and +0.05mm for nylons). These offsets are found in the custom g-code of the Filament settings tab for each material
