@firewirehn So you never actually loaded my default firmware or settings, now you have (I think) everything is OK.

@firewirehn Sorry I don't understand what you are saying.

@Dennis1950 Sorry I am the developer of T2Laser so I can't help you. The EleksCAM software only works with their modified Grbl 0.9j firmware, which is obsolete now and replaced by Grbl 1.1.

@KyleMC The Nano is powered from your USB port so it will operate and connect but the signals it sends to the motor drivers won't do any good if the board doesn't have power. If you have a volt meter check the laser connector + to - and it should be 12VDC, if not, your controller board has a problem. It could be a bad switch or input capacitor if the power supply itself is working.

@Ged It is wrong, you should not need to do that but EleksCAM software is obsolete and has many known problems. I wrote T2Laser for myself and it is very stable so you waste less time and materials, it just works!

@firewirehn Other software changes your Grbl parameters without asking, this is something T2Laser never does. It will still show my default firmware but the actual parameters are not the same, I suspect that's what happened here.

@firewirehn If you are using my default settings and Grbl 1.1e DEFAULT firmware then white is laser min or 0 so should not burn, laser max is 255 which is full power. If you start changing parameters from defaults without knowing what you are doing then just go to the Help menu and restore defaults then reload the firmware parameters from the Machine menu.

@Ged No idea regarding their software. I'm the developer of T2Laser and you load my Grbl 1.1e DEFAULT firmware once and then it's always good unless you change it with another program.

@KyleMC You should see 2 messages, Connected COMx @ 115200 and then Grbl Ready. Since the servo is working you are connected OK, if the motors aren't working it sounds like you don't have power. Check the power supply and on/off switch.

Test your hardware with T2Laser, it will work with the Eleks firmware although better performance can be achieved with my Grbl 1.1e DEFAULT firmware (but EleksCAM is old so it doesn't work with the newer firmware).
