Having trouble with Cutting Issues

I am having trouble cutting 3mm MDF & pine plywood. I have not had a problem up till now. I have set the settings in Lightburn Speed 240 power 100% with 8 passes. It still won’t cut through. It only scribe a line in the timber. I have done the same test in xtool studio & it done it perfectly. A 2 inch x 2 inch square. I have been on all lightburn groups telling me make sure the S value is set to 1000 which it is.Hoping you can help me please. Brad

1: Machine using: xtool d1 pro 10w. 2: What controller using: G - Code. 3: What’s the firmware in use: GRBL. 4: Using latest version: yes. 5: new or old issue: New. 6: computer in use: Hp probook 430 - g4. 7: computer operating: Windows 11

Which speed units do you use? I can’t read it in the screenshot. Make sure it’s set to mm/min.

If I’m reading the Cut Settings correctly, that’s 240 in/min, which is much too fast.

Change the Device Settings → Control Units setting to mm/min and, to continue using inch measurements for sizes, turn the Link Control and Design Units switch Off.

The Job Quality Troubleshooting guide has more background.

Seems like I am having similar problems.

Well before I started having trouble I was running 250 IPM/85-90 with good results in plywood.

Copied from a PM…

Several weeks ago my Falcon 10w stopped engraving so I bought a Laser tree replacement. It operated the same way. Low speed and high power. So I thought AI could help me quicker than 1 e mail a day with ther3ew support. Well we did some things that I do not remember, and it still does not work any better. In the meantime, I get a new falcon Module, and, same thing. So I don’t know if AI and me did something or what. So I was wondering if I updated to the latest version of LB if that may correct it. Here are my settings now.

What units for the Speed scale? This may be normal for your laser. I have a 10w machine and could run a comparison if needed.

Different machine, different laser, different problem, proabably a different solution.

Which is why it’s always a good idea to start a different topic …
