Thanx Zax and Nottingham82.. firmware was not required as eleksdraw is responding perfectly to commands. I finally managed to get a greyscale using velocity mode with 40 laser value and feed rate of 200 to 2000.. will do some more tweaking to get more good results .. thanks all for your help
Negative machine coordinates don't matter, change the display to show workpiece coordinates and use the custom button like I suggest. It will home to your limit switches, then you press the button and it will move to the lower left or center if you prefer and then set 0,0.
Let me know if you need help setting up the custom button.
The alternatives are to recompile Grbl with what you need or put in an automated move after homing but that's not recommended for safety.
@Alan-Legary The pause should shut off the laser, in fact I send 2 separate commands S0 and M5 to ensure it's off and disabled so your results are unexpected but your suggestion is a good one. The custom command buttons are great for many things.
@foxylad I am always willing to try something new. I have T2 running on my laptop out in the garage but do my designing/editing on another computer. Sometimes I make many things that vary just a little bit. This could come in handy for stuf like that.
I probably will not do any grayscale or pictures with it being that I have T2 and it is dead simple to generate the gcode through it, but for some basic black and white this could be useful
