Hi, everyone! I am using an 8W diode with a mini GRBL board. It was working fine and all of a sudden it started burning very sporadically. It will only burn half of the vector I’m working on and it will be burnt, the rest will be blank. I have changed out the actual laser, the control board, the motors, the power cord, and the USB cable. I feel like it is something in my settings. I am pretty new to engraving so please be patient with me. When I do get it to burn
I have to slow it down so much it takes 4 hours to do a 10" x 10" vector that would normally take an hour. I used to set it at 4000 mm/m and it worked fine but now I’m having to put it at 600 mm/m and sometimes it still doesn’t engrave. Does anyone have any suggestions? These are my settings in the console:
I apologize. It says GRBL 1.1 on my board. I’m not sure about what firmware is. I am new to engraving so I’m just learning. I don’t mean to sound ignorant but I really am. I am learning a lot every day though. I am about to order a new machine also but I have a couple of orders I need to get done with this one while I’m waiting on the new one.
Doing a quick search I don’t see a Sunshine 820 laser engraver. But when you connect to the console you should see what it’s reporting as your firmware version. Maybe post a screen shot of that and any links associated with the laser you have.
I would look at the $10=3 and maybe change it to $10=1 which I believe to be machine space positioning, I’d also make sure $30=255 matches what Lightburn S-Value Max is set to. I don’t expect either of those to change the speed your engraving at though. You might contact the manufacturer and see if they can give you the default settings and or suggestions.
Thank you! I have been working with my settings and it is doing much better now. I have been struggling with this for several days. I appreciate your help!
