    having an issue. with z and x axis wonder if anyone has had this problem or can help me.

    Trying to get the bugs worked out of my machine.

    I have a design of stars that should fit on a 9.5 inch wide board. It starts on the left and carves them in but
    when it gets to the right side my measurements are off. by like a half an inch. Also when the router is done
    it returns home it doesn't end at the same point.

    Also on my z axis if I tell it to do the design 3/16 of an inch deep buy the time it gets done its only 1/16 of an inch deep. My surface is parallel to the x axis and everything is level. I have checked all the screws for tightness. Belts are tight and everything. I can't figure it out.

    Also my x motor is getting hot like 135 degrees. compared to 92 degrees on the y motors and 112 degrees on the z axis. Any help would be great I am getting grustrated. I have run about 12 test pieces and everything keeps coming out different even though I am using the same design.

    Thanks,
    Atkinson934

    You say the X axis motor is getting hot is the carriage binding up ?

    What machine is it ? OX ? what power supply are you using ?

    It is the OX. Yes motor gets hot. No binding that I can tell. Carriage slides with no problem and little force.

    On my test last night the X motor went from 69 degrees room Temp to 134 degrees when the carving was done. i dropped my power setting on my driver and that lower the temp down to 100 degrees
    when it was done. but I can tell the carving quality suffered. I am going to bump it up to the next setting. to see what it does heat wise as well. I tracked the temps from start to finish. At start, then 25%, then 50% and finished 100%. Tracked on all 4 motors, it was an interesting test.
