Print speed question
I have a core one that I bought the day they were released and love it but have not been able to figure out one thing. When I start a print I can go to "tune" and there is a print speed setting, it's always at 100% when I start a print and if I bump it up to 200% it just about cuts the time that the print takes in half and often the print quality is pretty equivalent to if I did the same print at 100% speed. I have played with the settings in prusa slicer under the speed section and no matter what I do the estimated time for the print once I slice it is pretty much the same and no matter what I change in there when I send it to the printer that print speed setting under tune is always at 100%. So my question is what is that print speed setting under tune actually referring to and what is it increasing to make the print go faster but also what would I adjust in prusa slicer so that when I just send the print to the core one it just automatically prints at the 200% speed?
Hopefully I explained that clearly enough?
RE: Print speed question
Speed is constrained by max volumetric flow. For example if you set a max flow rate of 10mm^3/s and you a 0.4mm nozzle and 0.2mm layer height, then the max speed would be around ~110mm/s (10/.45/.2) The .45 is the extrusion width.
The speeds set by the slicer go into the g-code.
The speed setting under 'tune' uses the g-code as a baseline - so: If you sliced at half speed but tuned the printer to 200% or if you sliced at double speed but tuned to 50% - you would get the same speed.
Having said all that, in general: for quality slow the printer a little. For faster production, buy a second printer and run both at once.
Cheerio,
