For a tapping head to work well you need a FAST retract cycle to work the clutch dependably and you need plenty of head room for the Z axis. The advantage is the tapping head can be faster than a tapping cycle with less wear and tear on the spindle.

How to program the PART depends on several things. One being are you making 1 or 1000 of the same part ?? another being how complex is the arrangement of elements such as hole locations.  Another is does the controll have dependable canned(modal) functions.

 IF ( there is NOT in Mach3, BUT there IS in MAch4) there was a Modal Sub or macro it would be much easier ESPECIALLY if you could link a CSV file to the MODAL function(;-) .

CAD/CAM would be your friend here as well.

The  G84 cycle was NEVER a fully finished,fully debugged canned cycle. It has always had glitches in it . You would be better off just coding the cycles or using a SUB program to create them. Are the holes in rows or randomly placed ?

Is the spindle motor a single phase or 3 phase motor ??  A lot of motors cannot handle vast amounts of starts/stops in a duty cycle time period they tend to overheat and can shut down due to thermal overload(IF equipped). OR be damaged.

OK when it loads and stops on the IJs is there an error message ??

Post some of the code where it stops.

Early Fanuc post tend to wotk ok.  There is a MC post on the Newfangle solutions website under post downloads . Can't say if will work for your version.

(;-) TP

Just call up MasterCam and ask for a MACH3 post .

Mastercam SHOULD have a post editor in the program. The older versions did.

What exactly was the error message you got on IJs ?

Just a thought, (;-) TP

You MAY want to have your License file looked at it may be corrupted.

General Mach Discussion / Re: Configuring encoders
« on: July 01, 2015, 01:23:51 AM »
You have to close the loop at the outside controller where the Encoder feedback goes to the controller and IT closes the loop  OR user a servo drive that has feedback control where the encoders feedback to the drive to close the loop.

Mach3 does NOT do closed loop controll. You would have to close the loops at the drives or outside controller.

Mach3 and G-Rex / Re: Pause for Arc to stabilize?
« on: June 30, 2015, 10:48:41 PM »
You need to use the  ArcOK() signal in Mach3. Unless it goes active Mach3 will NOT move.

G-Code, CAD, and CAM discussions / Re: Reseting the Z height with THC
« on: June 30, 2015, 09:48:35 PM »
This should work BUT if you are loosing the Z positions then you are stalling the Z motor under THC control . You need to slow the Z down some so it does NOT stall.
