We’re working on a maintenance guide but it is based off the above content. We’re also trying to bottle Vactra No 2 and release a maintenance kit.
I can understand your frustration - unfortunately any machine that uses ball screws and linear rails needs oil applied. It’s one of the downsides of this type of motion and one of the benefits of V wheels. In the instance of your machine binding please contact support@carbide3d.com.
Typically if a machine was binding it would do so out of the box. It’s more of a calibration issue as opposed to a a fault. If a machine develops a fault you bet we stand by them and will get you up and running again, but if your machine is working there would be no need to replace anything.
