    You have me stumped. The only time I get the machine to z stall is if the bit misses the touch hole.

    You will have to explain to me exactly what the machine does. Does it stall on the first bob? Does it stall on the carrier side or on the the board? How thick are the sides of your carrier base?

    I hope I didn't confuse you with what I posted. Wasn't sure on this UCB (universal carrier board), but I now understand it better after Bergerud explained it. My bad also.

    The attached 30 second video shows what is taking place after I jog to the front mark opposite the front touch hole and press Enter. It appears I'm still doing something wrong because as you mention the bit misses the touch hole. When the bit moves to the right side it bobs and hits the carrier side and that is when the "Z Axis Stall" appears on the LED display. The UCB is constructed of 1/2" MDF.

    The touch hole is on the wrong side. Where the bit stalls is where the hole is supposed to be. You either have to flip the jig around or drill the touch hole on the other side.

    bergerud, thank you! After sending the video I read your comment again where you stated you only had the z axis stall when it missed the touch hole. Well the lights finally lit in this near 70 yr old brain. Yep, wrong side. I now have 4 touch holes, two that work.

    I don't think that 3/4 MDF is going to matter except it will limit your max. usable board width by 1/2". I just used my carrier today on a board that I could not get flat/square enough to work with the machine. Was getting tracking sensor errors or "clear board sensor" errors. Worked great in the carrier

    3/4" is ok. The bob holes in the side will not be in the center as they would be with the 5/8".

    The UCB is less than 4 inches high! What did you build?
