    Some controllers have settings that deliberately slow the machine when changing direction. But if that is not this case, then maybe it is due to the control getting bogged down processing many short...

    I don't know about Mach3, but some controller software only permits one M code per line.

    Actually, M5 is your spindle stop command, but M0 and M 30 might be set up to do this in the PLC (or...

    If the OP's method works at all, I'd be surprised. Why do we bother with rigid tapping if we can just guess a spindle speed and run a tap down the hole?

    That said, you could 'hob' the gear by...

    Any chance that the file system on the flash drive is not compatible? I'm not sure what it should be, but probably formatting the drive with FAT32 should be a basic standard that will work.

    I don't see any particular reason to worry about which way the head is set up to work. The handedness of the chuck thread is not a particular concern when doing spiral milling anyways, because you...

    I think of G92 as a shift of the G53 machine coordinate system. And since G53 underlies all the other work offsets, a G92 command will cause a proportionate shift of all work offsets.

    There is no...

    It is just a general error message. Typically, it might because of perceived overtravel past hard or soft limits, probably the latter would be the first thing to check out.

    Phone Haas tech support. But I'd have to wonder if it is indicative of a bad memory chip, assuming the machine does some sort of memory check on startup.

    Actually Geof, that interpolation pattern is kind of appealing....for a set of candle holders or something. Don't blame me if the new product line doesn't sell, though! :D

    Maybe you could rig up some extra large endmills by running a helical cut HSS slabbing mill on a short arbor. Just a thought, but interpolating with a smaller tool will probably work ok, too.

    I think Geof has outlined a decent method.
