I Have the Wainlux JL7 10w laser but when i try and put any speed 9000-6000-4000 mm/min the engraving is always over 1.5x slower?

TYpe $$ in console and copy/paste output here please
Also. what you “ask it to do” vs what it actually does in real movement might not be the same. Accelerations usually are lowered for stability.
