So I was testing boards today and got one that just wouldn’t cooperate on the zaxis. I turned the pot up, down, switched drivers, changed the feed rate. Nothing worked.
The solution was change the zaxis acceleration to 45 instead of 55. That is a bummer, I need to do more testing on this before I release a new firmware, but you might want to try it.
I would kind of prefer to have the acceleration high and limit the top speed for faster finishing passes on 3d milling. That’s where the testing comes in. I could also start shipping the z axis at 16th stepping if that fixes the issue. I have to get some parts prepped and orders filled before I can spend time testing, just wanted to keep you in the loop.
