Hi, I've tried out my conveyor feeder a couple of times now. The first 2 times the laserhead moved into position and then lowered on the z-axis as it should to engrave into the material (depth was measuring between 66 and 67mm for both of these projects).

I've now tried this for the 3rd time, using the same material and same depth settings but now the laserhead won't lower. I've tried engraving with the baseplate removed and used the troubleshooting to check if the laserhead z axis motor is working properly and I've had no issues there at all. The only issue now is when I try this on the conveyor, the z axis won't lower the laser head at all and I'm stumped as to what to do.
