I’d suggest you put it no more than 70%, I’d set it to 50%… if it’s going to fire, it will fire at either of those. I don’t think it’s a good idea for you to pulse your tube at 100% of some unknown current value.
I assume it’s a grbl board… (it’s in the grbl area) firmware usually announces it’s version and other information when it powers up or when connected to a console.
The console tab in the laser window should show this. You may have to Window → Console to enable that tab.
If you can copy/paste this initial information into a file or reply, it would help us help you… You can drag and drop some file types onto the reply window… Ensure you wait until it completes before proceeding.
The key to most of these issues hinges on what controller is in the machine.
I’ve seen these with a Ruida (dsp), numerous DLC32 (32bit) and Arduino (8bit) based grbl controllers…
If it’s new, it’s probably wired ok and it’s likely a software issue.
The first step will always be, is it the hardware or the software that is not operating as desired…?
So, has this ever worked correctly with Lightburn or any other software?
Might take a few to read this…
