Is anyone using visicut on there arduino/ramps setup? I can’t get it to fire the laser?
I have the latest development of visicut. Windows 7 using usb. Latest version of turnkey.

I tried it once, actually twice with mac and pc both. but for some reason I could not get it to recognize the board. So I gave up. I use LaserWeb now.

Another problem I had with it was that I had to remove the SD card and reinsert it back for it to send the job. So it partially works excepts for the laser not firing.
