Just out of curiosity, is there a macro to take the feedrate slide to 300 or 400% instead of 200% in CONTROL? Often times i make my gcode conservative and would like to be able to really push it beyond 200% once i start but then it’s to late.
No, our slider already covers the full range Grbl allows. See the Overrides section under Grbl v1.1 Commands · gnea/grbl Wiki
