" Lot more head/brain work than designing & building Progressive or Deep Draw Dies. "  :o

Say it aint so Craig, Say it aint so.  ;D

Yes the creast of the thread is FLAT not pointy .  That is the OPERATORS responsibility  to get the ID/OD correct for the thread.

 The G84 routine would NOT refhome the machine in the real world it would invoke Spindle Sync where the spindle encoder drives the Z axis to make sure the motions of Z and the spindle are locked together in motion. It is NOT a problem with a servo spindle but is required with a VFD driven spindle motor.  Might want to look into that part for your customers that do not have a servo spindle (;-).

M19 would be to position the spindle for a tool holder AND to REF the spindle to a known point for peck tapping. It can be 0.000 or any degree from there.It should be adjustable to allow for different tool changer setups. Simple Macro there.

G28.1 C0 ( Moves to C home index point)
G0 C180.000  ( Moves to orientation point)

The NICE thing about Mach3 is you are not limited to just 3 param inputs for a macro call the number is LARGE.

M9000 #1=1 #2=22 #3=333  ,etc,etc

You can input as many #vars as you like and MACH3 calls the #vars first then runs the Mcode (;-)

I would like to see the picture of the machine it will help me understand how it works axis wise. That way the code will be easier to write.

NOW it is a gamble to mix CB and Gcode in the same macro. Most times it works and SOME TIME it does not due to timing problems. (;-) IT can be PC dependant.

Are you sure you have the switches setup correctly ? I have never seen Mach3 not home if setup correctly.

If you look on the diagnostics page and push the switch manually does the correct HOME led light up and then go OUT when you release the switch?

AND no your macro will not work correctly.

What about HOMING does not work for you?

LOOKIN GOOD Craig, (;-) TP

OK i made some room and have 10 extra function buttons available.

IF you can explain what axiss you use to do the internal external threads I will give it a go. Should not be that hard :D (famous last words).

A picture that shows a distant view that shows ALL of the machine would help.

Mach does support G84 motions BUT it does not sync the Spindlle to the Zfeed. IT may be possible but i will not let that cat out of the bag.

A servo spindle can be refhome back to the index mark to set the Spindle to 0.000.

An M84 can be created to create a rigid tap function. It can have 3 outside param calls P,Q,R to set inside variables.  The sequence can be done as a SUB so it SHOULD be able to  simulate the G84 function quite easily.

Crusty OLD Machinist (;-) ???? I resemble that remark a great deal (;-).

I can shuffle some more room on the page so IF you get time send me what you have code wise for what you do. I will look it over and see what we can do with it. Top secret of course(;-)

Single point threading THE HOLY GRAIL.  IT all depends (;-),  we will just throw it all in the frying pan and see if we get fried fish.

Could we PLEASE get a Printer option for the Gcode Editor AND the LUA editor.

Thanks (;-) TP

Steve When Tapping do you prefer a { Feed per (unit)} feed OR {Feed per REV} feed ?

I prefer FPR as it is easiest to program AND you can SSO and the feedrate follows the RPM.

Newfangled Mill Wizard / Re: Indexed drilling using 4th axis
« on: January 27, 2015, 08:14:50 PM »
You have 360 degrees and 55 holes so each index is 6.5454 degrees   360/55 =

and you have 360 degrees and each index is 6.5454 degrees so each cycle has 55 indexes  and that needs to be rounded down   RND  360/6.5454= 55.0004  =  55

OR just make #4 = #2 as that is how many holes there are so that would be the the number of indexs and SAVES having to round down the number.

6 of 1 or 1/2 dozen of the other (;-)
