Hi everyone, yesterday I finally installed the 890*900mm extension kit for my Scuplfun S30 Pro Max 20w.
After making various adjustments, everything was fine… but I don’t know why, I wanted to fine-tune the axes and started with the X-axis… but after I “wrote” and did a frame test, it messed up everything!!
If I frame something by placing it on my laser, Lightburn shows me the position I want to engrave, but in reality, the laser moves in different directions than Lightburn!!
It also created the “A” axis, and I don’t know how to delete it and/or set the default X-axis.
I also tried resetting Lightburn by deleting the prefs.ini and prefs.old files from the favorites folder, but nothing…
First, reset the firmware by sending $RST=* via the console. Then the laser is also reset.
Additionally, make sure to adjust the motor current correctly (has nothing to do with your current issue, but will be the next) as explained here: Workspace extension kit - Diode Laser Wiki

Hi, thanks for replying… I already boosted the motor while I was installing the extension. I had to rewire the cables on the motherboard and increased the boost as described in the steps on the Sculpfun website. What happened today was because I wanted to increase the precision of the X and Y axes, but it would have been better if I left it alone! 
No can do. Precision is determined by the physical design of the machine.
You may be able to improve the performance of the machine, but Sculpfun does a pretty good job of that already. Although you extended the frame, you still have the same mechanics moving the laser around. For most projects, you will not obtain max speeds anyhow.
Don’t forget to allow for that huge inertia laden laser head in your max travel parameters.
Hopefully they updated the guides since they recommended to turn the little screw 90 degrees at first which cause many, many issues. You only need to turn it 45 degrees maximum. Otherwise you will get lost steps all the time.
Si, in effetti ho ruotato di 90° come indicato nel video…che problemi può dare? In caso torno indietro e ruoto solo di 45°
Grazie!!!
The motors get too much power and the driver is not able to provide it. Both the motors and the driver start to heat up and at some point the driver will start to shut down during operation. You will notice that movements in y-axis are not executed as planned.

Ok ne terro’ conto e in caso modificherò la potenza!!
Gentilissimo, grazie.
