When I try to engrave or cut at any speed under 10mm/s the laser

When I try to engrave or cut at any speed under 10mm/s the laser cutter speeds up to an insane speed that does not allow it to cut or engrave anything. Any ideas as to what is causing this?

What software are you using ? Im a complete newby and have had my laser a week and have been fighting with all issues so far. But think i’m nearly there. I had a configuration error in settings. Ie wrong laser was set up in there and mine worked one minute and then went mad with other settings. Worth checking that first.

You probably have the wrong mainboard number set in corelaser settings. Check the number on your board and make sure you select the right one in the settings menu
