@mbyrd777 Yes. I wrote T2Laser as a replacement software for these machines.

@Filiprobin I have never heard of this before, what software and firmware are you using? If it were 45 or 90 degrees that would make sense and can be changed but other angles would be strange.

@amacin You need to add a hatch fill, depending how you are loading or creating the design you could do this in T2Laser or for more options add it in Inkscape and load as DXF (vector).

@DDUJ It could be a firmware issue but more likely the MOSFET has failed, you would require a volt meter to check the controller outputs. If the D11 output on the Nano is working and the MOSFET is not switching then you need to replace the MOSFET or get a new controller.

@Hiram-be What version does it show in device manager? It needs to be version 2011 that is provided in T2Laser, then it should work unless you have some other USB issue. Make sure you reboot after install.

@Hiram-be If you are using T2Laser you can click Help / Install CH340 but if a different driver is already installed Windows may refuse to replace it automatically, in that case you must go to device manager and manually replace the driver with the one provided. If you are using other software you should contact their support for help.

@Hiram-be If you are connected to the Nano and it does not appear as a COM port then either the driver is incorrectly loaded or the device is faulty.

@donovanpl123 Set it to Uno, or your boot loader is corrupt.

@donovanpl123 It switches from USB power to external power. It should not be changed.

@Nam-Luc-Tran Your belts are loose and the axis has backlash. Servo value should be 55 or less to prevent over travel of the servo and damage to the gears.
