It would be handy to have a history of your work offsets under the Work Zero button, that way if you accidently reset your zero position, or if you have multiple sheets on your table you could pull up a previous position.
Along with that one of the machines I ran had a couple preset positions you could set, say a load position where it placed the head in a out of the way corner for ease of loading and a service position that made it handy for changing tips. On that machine the control station was in the opposite corner from the home position, so it saved a lot of walking.
Matt, separate work offsets were the intended workflow for keeping multiple sheet origins and preset positions. Your request prompted us to double-check that everything was wired up properly, and we found some mistakes—parts of the implementation still assumed G54, including the torch’s Z touch-off routine. We’re fixing those in the next release.
After updating, you’ll be able to set Work Offset → Use active work offset in the FluidNC Plasma post settings, then re-post your jobs. That will leave the offset selection up to you at the machine instead of having the file force G54. You’ll also need to apply the bundled fire_torch update under Machine Configuration → Subroutines.
For multiple sheets, select G54 in the DRO and zero X/Y at the first sheet’s origin, then select G55 and zero X/Y at the second. Each offset keeps its own zero, so you can switch between them without resetting it. JC3 will also remember the selected offset for that machine.
Spare offsets can serve as load/service positions: zero their X/Y at the desired location, then select that offset and use Go to Work Zero to return there. Just select your cutting offset again before running a job.
That covers the saved-position workflow. Recovering a zero that was accidentally overwritten would still be a separate history feature.
Okay, that works.
Perfect! Planning to get the V2.6.0 release out by tomorrow evening
