    Just dove into the router side of the CNC world. I own a 4x4 plasma table as well. I purchased the 1010 Workbee and have it set up and here is the problems I've ran into

    I am set up and jogging the machine and have ran into 2 problems.

    1 - My x axis motor doesn't know which way to go. I hit X+ and it will + for a few steps then start - then back to +

    2. When jogging at first my X motor was bound up and not wanting to turn. I found the problem being the nut block for the lead screw was tight. I loosen in up and it solved the problem but now is loud due to loose parts

    Anyone ran into this or have any solutions?

    Is there possibly a loose wire in your X?

    Hi @Matt Simon, the symptoms you describe sound exactly like there is an intermittent connection problem with one wire on your X axis stepper. The noise could be many things - check your backlash nuts (on a new machine it is unlikely you will have much if any backlash - squeeze them gently together before clamping to the gantry plate) and your eccentric adjustment. If you can detect movement by hand on your X axis also check that you have no play in your leadscrew. If you have check the lock collars are pressing firmly against the bearings.
