Here is the same file only run from an SD card to remove the USB connection as an issue. Oh well it was just a thought and the burn was about the same. Regarding the 1KHz I have noticed that the sound of the laser is a much higher pitch that when it was at 7.87 or 50 Hz. Just observing things.
I wonder if my flavor of Marlin / Miguels firmware is not the issue. Maybe some delay between the Laser command and the X / Y axis commands?
Mark posted a similar thought as I he did mention moving to a GRBL board based on a potential updating issue with speed. I’m not familiar with the difference between Marlin and GRBL. Any thought there? Maybe this is just a wasted effort, aside from the learning curve which is great.
