I have an engraving job and I have an Ortur LU2 10a and an Ortur LU2 4LF.
I did image 1 with the 10a and image 2 with the 4LF. Same LB file and settings. Any suggestions about modifying the 4LF setting to get a better engrave? I want to use both lasers at once.
I am using a roller and doubled my overscan. No real improvement. The 4LF has done well on other tumblers. Maybe it is the coating. I like the x axis because it doesn’t move the tumbler around so much.
The error you received usually happens when the motherboard rejects the firmware file. You might be trying to upload the wrong firmware for your machine.
Please enter $I into your console window with your laser connected to learn what machine you’re using. Please report back on what it says.
