Hi, I know this forum is more for Lightburn, but I need help with LaserGBRL. I’m making a CNC plotter and I’m using an Arduino with a CNC shield. I think I’ve already fixed the hardware, but the following alert always pops up: (Image 1)
From what I’ve investigated, it pops up because one of the limits is being pressed, but I don’t have them installed or activated. If anyone can help me:
Causes already verified:
Bad USB cable: Buy a new one
Power supply: I have a 12V 1.5A and 24.5A
…that’s probably a slight understatement

Sorry if I didn’t make myself clear, I’m using a translator.

You don’t have to apologize, it was just a bit funny. (I use google translate a lot myself) It may well be possible that a kind soul with knowledge of laser GBRL can/will help you, but Laser GBRL and LightBurn are really 2 different programs. Good luck anyway, hope you find a solution.

This indeed looks like a bad connection, there are multiple incorrect protocol values sent. Exchange the cable for another one. It might take a few cables until you find the perfect solution.
I don’t really see any issues in your logs, there is no stop etc. The x limit switch seems to be activated, but as long as you don’t activate hard limits, this is ignored.

From what I understand and from what I know about lightburn, there is a similar error that has to do with when it reaches the maximum limit value that the axis can move.
I focused my attention on the parameters $130 to 131, and $20 and 21 eventually.
These are different software but the board parameters should perform the same function.
I also started with Lasergrbl but quickly switched to Lightburn. I haven’t gone back to the previous software since.
