I always tap in G95 mode. Makes the math easy on the feedrate.   Heck take it apart it is NOT that complicated.

There's no need to take the tapping head apart to understand how it works.  It has clutches in it.  As long as the tap is moving down, the tap will keep turning CW.  When the tap stops, the tap will be dis-engaged, and, shortly after, the 2x reverse gear will be engaged, backing the tap out.

Ray what I was referring to is MANY of the older units I see today need to have the Guts cleaned AND the oil changed in the head. They get contamenated with coolant over time. IF left it may corrode the internals THEN you really have a mess.

The way they work is there is a spring loaded neutral positon. When you downfeed and the tap touches the material it pushed the forward clutch into gear. When you stop the downfeed the clutch releases and goes into neutral. As you do a rapid UP feed it engages the reverse clutch and backs the tap out .  The unit is a floated head so a little mismatch on feeds is NOT a big deal.

Using the G95 mode without an RPM index will work fine as long as you are close.

Just a thought, (;-) TP

Tapmatic has a demo video on youtube showing many different size heads in action with the tap size and RPM listed.

ONe thing you do have to watch for is doing it their way you can TEAR the top thread when the tap gets to the top of the hole AND it is extended too far the spring back can tear the top thread when i t retracts back to center.

ok i have finally received my spiral taps.

so i can now test the tapping head.

let get down to coding, what do i need to use here?

tap is an m3 tap, the hole is a through hole and say 10mm thick work/or 10mm deep hole

Are they spiral flute or point? Spiral flute are really meant for blind holes and spiral point are best for through holes.
With spiral point the chips are pushed in front of the tap and out the hole so there is less chance of the chips snagging and causing problems.

The code would just be similar to what is in the tapmatixc manual except personally I would use G95.
Did you ever get info on the spindle speed sensor?
Maybe wouldnt be too hard to add a slotted disc and opto if you cant use whats there?
