Hey, I’ve been playing with a Sherline mill for a while. After cutting some material, the zero of the x and y is shifted to the positive direction. It’s probably somewhere around 0.005” to 0.01” off from where it started. This is really frustrating. For example, I need to cut a cylinder shape and then drill a hole in the middle of it. But after that cylinder shape is cut and I start drilling, it’s noticeably off center a little bit.

I have tried a new, sharp end mill, as well as reducing speeds, so I’m doubting that’s it. I can’t really check the backlash right now. I will have to get a dial indicator so I can look into that. Just wondering, is this normal for a Sherline?
