@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
First. Thank you all for the kind words and support of T2Laser. As most of you know I wrote it for myself as I could never get Benbox to work, but have continued to develop it based on user input and requests.
I use T2Laser on my EleksLaser, EleksDraw, a K2CNC and a K40 CO2 laser. On the K40 I swapped the proprietary board out for an EleksMaker L6 (you could use a Mana SE or CNC). There are easier options like the Cohesion 3D board which is also Grbl compatible.
The advantage of using T2Laser is it supports Velocity Mode which works much better than TTL/PWM with the CO2 lasers, or at least it does on mine.
