Monport 40 watt laser will not cut

Laser connects to LB, it will home , frame but when I push start it will not cut. It acts like it is but I have no Amps. I can push the test button and it fires ok but when I hit start it goes through all the motions but on the amp meter it only shows 1-3 amp. Yes the knob is turned all the way clock wise. I have tried different power settings , while running, one time I pushed the test button and it fired and amp meter went up to 17amp I am running HP desktop computer windows 11

My assumption is that this has never worked with Lightburn… Did it ever work with any other software?

I believe that’s a grbl machine… Did you set it up as suggested by Lightburn grbl setup?

Good luck

New laser new operator. Yes I did set it up with grbl. I am cutting 1/8 in clear acrylic. I may have got it. I increased the power to 90% on line and it did cut it out. I just didn’t think I would need it that high. Thanks for your help
