Things I checked:
My material was clamped down and flat
Laser head was properly focused for correct material thickness
Laser head appears not to be bent or broken
I assume this is an out of order type thing, so I put an out of order sign on it.
Yes I noticed some similar behavior in my really quick test the other day, we are hopefully going to be aligning it this week. Thanks for putting an out of order sign, as it isn’t really usable until it’s fixed.
Just want to add that we used JB Water Weld to fix the leak in the water chiller. We suspected the leak was right around the copper refrigerant tubing as it enters/exits the water reservoir. JB Water Weld is quite hard to work with, especially since it’s hard to get in and clean the surfaces properly in this chiller, but has the nice property that you can refill it with water immediately and it’ll set underwater. We applied liberally.
Anyways, should probably keep an eye on that chiller. Every time it gets banged around or moved its liable to develop a leak because the strain of the entire evaporator is on that seal.
