I'm done messing around Novusun / Digital Dream products. The EC500 V5 never worked from day one. The EC300 and NVEM have unreliable probing. The probing is intermittent. Strange thing is the input activates but the probe functions are not triggered, its 50/50. Almost wrecked my probe. I'm now running Warps boards with CNC4pc breakout boards. I had high hopes for these. Funny thing is everything works in LinuxCNC
