I started to do my carving this morning. My board is 1/2" thick, with rails stuck on the sides (well actually, my calipers measure it at 0.503").
When I first started it, it started to measure the board, and stopped, telling me to clear the board sensor. So, I took a can of compressed air and blew off the optical sensor underneath. That worked, and I proceeded.
It measured the board, homed the bit, and went over and touched the flapper. It started to measure the thickness. It gave me a Z-axis stall error E06-0313. I retried it again, and noticed it was actually driving the bit down on the bar assembly on the sliding guide.
So, I checked the rollers, all working fine, and moved the head back and forth and up/down. Felt ok. Just as a precaution, I vacuumed out the nooks and crannies, etc... everywhere I could reach.
So I restarted the process again, and now have a persistent board sensor error. I blew it off again - no luck. I tried scrubbing the sensor with a toothbrush and blowing it off - no luck.
So now I am dead in the water so to speak, and not sure what to try now... for either error.
I need some help here, in terms that an amateur like me can fathom.
