Hello all, I have had my 60w OMTech Laser for about a month without any issues until recently. I was cutting some Monograms for Gifts without any problems, I completed 4 of them and next I was attempting to engrave a door mat. I was able to frame the work area and the Laser returned to it’s origin, I then clicked Home and the Laser went a little crazy. It moved catycorner to it’s home position and started banging against the front of the machine for a second or 2 and then moved back to it’s home position and was banging against the back of the machine for a few seconds. Now it does not respond to any commands. So I shut the Laser down and restarted it and now it will frame the project and return home but, will not move from the home position. This all happened in the same day. ( the laser was never turned off except after the problem started ). I recently upgraded to Windows 11 and have been runnig the laser with no problems.
What’s happening is called ‘overscan’, it’s adjustable in grbl, but DSP controllers have all the code and figure it out automatically.
Say you want the head to go 100mm/s and the image is up against the side of your workspace.
The head cannot speed up to 100mm/s in zero distance, consequently it couldn’t slow down either.
That generates that error…
Move your design or make the size smaller to fit the area. If you have a 5050 work area, you cannot scan full area, some of it will be used to speed up and slow down. You can slow the speed down and that will reduce overscan.
