I am new to the laser engraver/cutter arena and am currently struggling with getting my upgraded k40 laser to operate with LightBurn software. Currently I am unable to move any of the axis after one or two initial movements. It seems to not be sending any commands to the controller. I also have atte…

I assume it detected the device as Smoothieware? @raykholo - Do you know if we need CNC firmware or a Laser build?

Yes it did. It actually detected two smoothieware controller (both with the correct size that I had set in config) but plugged into only one board via usb with no other devices plugged into the laptop

You haven’t said yet if this has ever worked correctly, or works with other software, so it would be …

I am using a newer laptop with windows 10, a very short usb cable along with a number if upgraded items for the unit. I haven’t had this operate properly at all as of yet due …

Unfortunately as a new user I can only post one pic so here it is :flushed: [image] I have installed a dedicated 10A 24vdc power supply to run the steppers, 5vdc to the board and the 12vdc led lights. I am using buck converters to step down the voltage to the smoothieboard and lights and running th…
