Until there is some sort of acceleration/deceleration planing implemented, the speed is pretty limited.
Imagine the sled could sort of ‘swing’ at sudden direction changes.
We have been at 1000mm/minute but had to go down to (700 now) as with heavy sleds moving horizontal at the top of the sheet, the motor pulling could not keep up with the other motor feeding out.
Edit: added link Increasing the Max Feedrate?
Edit2: edited current feed rate 1.11 Use with care! The setting is found in the firmware folder in the file Settings.cpp
I would not, but you could edit the number in the arduino IDE before uploading to the mega.
Note that the arduino IDE stores that change without asking, so it’s better to work on a copy.
