Has anyone played around with this value in the firmware for the R2? Before I kill a board or driver testing, I wanted to check and see if anyone had tweaked these settings with any luck. The max extrusion speed seems to be quite low before I start losing steps on the extruder (I use a lot of PETG @ 242C w/ .3mm layer height for part testing). Increasing the temp only nets me a small increase in feed rates. I understand that this printer doesn't utilize any gearing on the extruder for higher torque but it still seems to underperform with extrusion speeds in comparison to older Robo offerings. Any input would be helpful. Thank you!
