    Brent, for peck tapping you just program deeper Z coordinates on the lines following the G84 and before the G80.

    If you try to re-tap the hole after calling the G80 you may cross-thread it though...

    If the indexer controller is connected to the Fanuc, the M-code used will be determined by the machine builder and whoever interfaced it. There is no standard.

    There should not be "slide drift". When you watch the machine rather than the CRT, doesn't the spindle stop at the same time as the Z axis stops at the commanded Z position? That's how rigid tap is...

    Normal behavior. Here is a clip from the 0iC functions manual.

    Dry run is valid for G84 (G74). When the dry run is applied to the tapping
    axis speed of G84 (G74), tapping is performed. The...

    Absolutely the case. The CNC sends notice to the PMC by address F76.3 that rigid tapping is commanded. The builder's PMC ladder program at that time could stop spindle rotation in preparation of...

    I've only used one and that was a Lapmaster. Dead simple model. Bought used for <$1k IIRC. Not as big as you will need though. It had 3x 12" pods. I think finding one as big as you will need...

    I've never looked at the ladder logic for tap retract so don't have an idea of how to change the behavior or what options one would have. The recovery behavior of an e-stopped or alarm stopped tap...

    I'd try the orbittool from JW Done. they are designed to deburr hole intersections, but I think they would work for what you need.

    I would not do that at a trade show but every private machine demo I was given had an unexpected e-stop done while tool changing. It really helped separate the men from the boys. More than one demo...

    Since parameter 24 bit 2 is 0 already that is set for the Fanuc side of the control to not use the spindle up to speed signal. This makes me think that there is some logic in the machine builder's...

    Yes that shows that 120 bit 4 is zero.

    Is parameter 24 bit 2 set to 1? If it is then set it to 0 and see if the machine will feed. If it does then you will need to figure out why diagnostic...

    What is the state of DGN G121.4? This is the e-stop signal from the PMC to the CNC. It is an inverted signal in that 1 means all is well and 0 indicates that the PMC is telling the CNC to e-stop.

    Per the manual F149.7 is not an inverted signal.

    In post 307 you say that F149.7 is open. Does that mean off (0)? In post 309 you say it is on (1) whether or not the machine is ready. This is...

    F149.7 might be an inverted signal (1=off, 0=on). I'll have to look through a manual to refresh my aging memory.

    Are all your power supplies working????

    Got it. I'll look at it later tonight and get familiar with the layout.




    F149.7 is the CNC ready signal from the CNC (Fanuc side) to the PMC (MTB side). If DGN 149.7 is 0 then the CNC is not...
