Jeff,
We updated the plugin with less sensitive slider. We did remove the Torch On button but you can turn torch on with M3. M5 will turn off the torch. We were able to turn on torch with M3 and jog the machine with no problems here. We are not seeing any issues with the torch up/down signals from the Proma 150. You can try setting the THC Max/Min input labels on the screen to values that allow a larger range of motion.
