# Laser moving too slow when cutting

i have set my laser up to do a 3D image engraving speed set to 2500mm/min however during the cut it slows down to 100 or so mm/min

100mm/min is very slow!

Go to the Move window and enter the speed of 2500mm/min, then click on the arrow buttons to move around, can you move at 2500mm/min?

You can also see the GCode instructions that were sent to the laser if you enable ‘Show all’ in the Console. Do you see ‘F2500’?

During the whitespace movements it travels at 2500min only during the burn sections does it slow down… seems to be only when doing greyscale/jarvis image modes
