ok so I finally have the machine (x50) mounted and squared . I have my monitor and keyboard all set up. Fired it up, homed the machine got the yellow z over. I’m going to get latest firmware update 1.9, I believe and install it using a usb, can’t get wifi working yet. can I go ahead and use the machine manually to scribe the waste board size on my table with the z still showing yellow. also the machine came with a light oil on it . should i clean it off before scribing table or leave it on for lubrication . I’m thinking remove it otherwise dust will stick to it. sorry for the dumb questions. thanks

Hey Butch,

oil has to be on the parts that are described in [Onefinity CNC maintenance](https://forum.onefinitycnc.com/t/onefinity-cnc-maintenance/9004), which are the ball screws and the chrome-plated hollow shafts, but not as much that it would drop down.

Sure. You can safely ignore all limits warnings as long you have not loaded a g-code program of your own.

Once you will have, and will have probed your workpiece, the limit errors will tell you if your g-code program tries to mill outside the machine’s working space.
