Hello there. I have a foxalien laser 20w and i’m experiencing some issues in cutting mdf board, 2/3/4mm thickness. After i finish the laser configuration i made some material test. The first one (10x10 squares) told me that i can cut mdf 2mm with 200mm/min speed and 70%. After that my laser don’t cut anymore, i tried several tests but nothing. I tried to clean lens, focusing again e the wiring cable is good. Any suggestion? Here my $$ configuration: $$ $0=10 $1=255 $2=0 $3=0 $4=0 $5=0 $6=0 $10=0 $11=0.010 $12=0.002 $13=0 $20=0 $21=1 $22=1 $23=3 $24=25.000 $25=1000.000 $26=250 $27=3.000 $30=10000 $31=0 $32=1 $100=80.000 $101=80.000 $102=1600.000 $110=2000.000 $111=2000.000 $112=500.000 $120=300.000 $121=300.000 $122=30.000 $130=380.000 $131=380.000 $132=50.000 ![000F2F59-9EF0-4ACB-9E42-A845F9CD436C_1_102_o](https://forum.lightburnsoftware.com/uploads/default/original/3X/0/3/03c0b08aab44239b79080da93c4ea347cd6c0212.jpeg) ![F97045C2-EA4B-41C3-BAF7-9BDB15622BF0_1_102_o](https://forum.lightburnsoftware.com/uploads/default/original/3X/9/b/9bc678fb294d9c7a8228326b7c8f47f73915865a.jpeg) ---

Hi, thanks for your reply! I checked and $32 is set to 10.000! The only adjustments i made was for setting the 0 axis because the origin wasn’t at 0,0 Maybe i try to reset all the grbl settings?? ---

Likely no need to do this. ---

> [@danilo982](#): > > In device settings is set to 1000 only! Change S Value Max to 10000 to match $30. Also, make sure that $32 is _not_ actually 10000 as you indicated earlier. It should be set to 1. That should address your power issue. ---

got it. changed to 10000 in edit-settings and $30 is 10000 too. ($32 is 1, it was a typo before) the i run 2 material tests: on a 3mm mdf the laser cut as shown in the photo, whereas on the 2mm don’t cut again. i don’t understand it. mmmh ![5424B6A5-8C84-4134-9738-B94065BCDEAE_1_102_o](https://forum.lightburnsoftware.com/uploads/default/original/3X/1/9/19e52fd57905d2ca39eb6a501aad7b1814908636.jpeg) ![31D6CDF6-682B-45B1-8032-90CA362F8659_1_102_o](https://forum.lightburnsoftware.com/uploads/default/original/3X/0/b/0b1f6fb471f233a5458f52bed456b4cc8b0b9e66.jpeg) ---

The materials themselves look different. The 3mm is darker. If the density and material is also different then those factors could explain the difference in cutting. ---
