Great, the Z+ is pretty good, way better than the old belt Z which had to run much slower.
Check all the V-Wheels, I run mine tight enough that I can just turn the lower wheels with two fingers whilst the machine is stationary. It’s very easy to end up with a loose V wheel or two without realising.
On the belts, funny you should ask
I run my belts at about 70-90 Newtons, too much is bad for the stepper motor shafts and bearings. It’s very easy to check with the phone app method.
