    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...

    What kind of gear train do these trunnions use?...

    What kind of gear train do these trunnions use? Are they not both worm drives? I cannot visualize backdriving a worm that is being held with a zero motion command, and not have an axis alarm raised...

    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...

    What about tool changer homing? Does this occur normally?

    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.

    Any chance it could be something else altogether? Some times the error messages just don't reflect where the problem actually is. Maybe a bad spindle encoder (run a trial G3x)? Maybe a change in the...

    I don't think anything essential is ever cut, rather you get more and better tweaks to existing features, version by version. I think one of the things in XR4 that may prove most useful is the...

    I don't think you'd have much choice except to grind the face. You'd need to set up a vertical grinding spindle on the table of your machine, with a cup style wheel, orient and lock the spindle so...

    Laser cut pretty nice....compared to a plasma torch or an oxyacetylene torch :D

    But I have my doubts about the cutting accuracy being better than .001".....maybe it is that repeatable (with some...

    First, make sure that the small o is correctly typed as an upper case O.

    Do not put the program number within the parenthesis. The file name should be within parenthesis.

    If the file is called...

    Simple Harmonic acceleration is kind of an open-ended specification. A Scotch yoke has 4 phases of harmonic acceleration/deceleration because it operates through a 360 degree crankshaft, but in this...

    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.

    Rather than using a ballnose tool, I'd be tempted to use a tool with the proper diameter to machine the radius of the screw flute. To do this, you'd...

    For aluminum machining, I'd recommend YG endmills, the 3 flute variety with high helix. These also have a polished flute for better chip evacuation. They are typically uncoated and will last for a...

    At what circumference are you expecting to hold this tolerance? Is the minimum arc command still .001 degree on this table/machine combo?

    It might have backlash, but I'd be surprised at a lack of...
