2 Stack or 1 Stack gcodes

I have been using:-   covid19_rc32_4pcs_complete_025mm_pet__5h45m.gcode

and it's great to achieve the 1 hour 20 mins per print, but are there gcodes ( not necessarily stacked )

to achieve the same time per mask in order to use up 'end of the roll' filament ?

RE: 2 Stack or 1 Stack gcodes

Are you using a 0.4mm nozzle? You can certainly reduce print times with a larger nozzle. A Verkstan style frame prints in about 20 minutes with a larger nozzle. If you're stuck with a 0.4mm nozzle for now, try increasing the Maximum volumetric speed setting under Filament Settings. Print quality will go down, but that's not much of an issue with these prints. 

We're avoiding the stacks due to poor finish quality and the difficulties it introduces with disinfection. It's not all about speed. Someone locally has been distributing frames without the clear shields. Frustrating for the recipient.

I'm using the one that came with the MK3S printer, so 0.4 mm I think.

I was really just looking for gcode that was like the 4 stack, but fewer masks, say 2 or 1, so not really stacked.

Being somewhat inexperienced I was assuming there 'something' in the gcode that optimised the print process,

and so gave the quick ( 1 hour 20 min ) print per mask.

I had noticed that the quality was not as good as one I had sliced (  covid19_headband_rc3_1pcs.3mf ) but took

about 2 hours 37 min. With the stacked gcode, I also obtained a few failures ( 20% or so ), so maybe, as you indicate

it might be best not to use the stacked variants. Thanks for your help

If you have a MK3S, then continue as usual, the printer will detect the end of filament, stop printing, ask you to press button to remove bit left in the extruder, then tell you to load the new filament, and then continue as if nothing happened. Ensure that the end of the filament is not kinked and straighten the last 40mm, that way you can ensure there are no problems when unloading.

Thanks. I guessed it would do that, however, I was on my last roll of that particular manufacturer's filament ( PETG), and because of the nature of the print ( PPE mask for the covod-19 pandemic ) did not want to continue with a different manufacturer's filament. I had no more PETG anyway. Also, I was interested in GCODE for a single or double mask print, derived from the 4 stack. I think now, that I am leaning towards the idea of not using the stacked gcode, as suggested by 'bobstro'. Thanks again for your input,

The printer will detect the end of the filament IF, and only IF you have enabled that option under SETTINGS-Fil. Sensor [On/Off].  My sensor has failed, so I had to turn it off, otherwise I could not print anything. If you time your jobs carefully, and are at the machine when the filament is disappearing down the "rabbit hole", all you have to do is manually feed a new, trimmed filament into the hole and maintain a little pressure on it until it is grabbed by the extrusion gear. I have used up a LOT of short remainders on prints where a change of color is of no consequence. If you have patience or nothing better to do, you can also feed in multiple differently colored pieces on the order of 2"/50mm long for interesting variegated color effects.

Sounds like good advice, so thanks for that.
