Good afternoon! Snapmaker J1 has a preheating function for an inactive extruder, namely - The non-working extruder preheats while on standby, and starts printing right after the working extruder leaves, significantly reducing your waiting time. This functionality works in his native slicer Luban. When working in the Prusa Slicer, the inactive extruder starts heating to the printing temperature only when the active one has worked out and is parked. Tell me, is it possible to integrate the preheating functionality into the preheating, perhaps using scripts or tool replacement code or something else? Thank you.
Hi Palagach,
Are you using sm2uploader to upload and ‘fix’ the gcode for the J1?
If not, that is likely the source of the inefficiency.

Thanks for the answer! Unfortunately, the problem is that I use sm2uploader and it doesn’t help (I don’t understand the reason yet, it seems that the connection to the 3d printer is correct.
That is expected. Maybe the fix for the g-code is not needed anymore (newest version of PrusaSlicer/OrcaSlicer).
You could try starting sm2uploader with the -nofix argument.
Btw, I’m using sm2uploader v2.8. For Orcaslicer 2.2-beta I added the -nofix argument as it looks like to me Orca is now handling the two extruders properly. Have not done extensive testing yet.

Yes, I found that in version 2.9 of sm2uploader, preheating was cut out, since it is used for OrcaSlicer, where preheating has already been implemented into the program. I tried to use it with prusa, where there was no preheating integration yet, maybe that’s the problem. Thanks for the help. I solved the problem by completely switching to Orca, it’s good that it’s built on the basis of Prusa. OrcaSlicer Nightly Builds for Snapmaker Community - Dev Version
