General Mach Discussion / Mach3 running multiple tap files?

« on: March 11, 2014, 03:36:13 PM »

I have a part and I need to start one program (tap) then do a manual broach and then finish the part with another program (tap).

At present to change the tap file I close the auto screen and then go back to it. How can i load another tap without going off the auto screen?

thanks

G-Code, CAD, and CAM discussions / G76 threading problem

« on: March 11, 2014, 03:33:33 PM »

Got a problem with G76

G0 G90 Z5 X9.84
G76 X8.95 Z-21 Q2 P0.75 J0.03 L45 H0.05 I29 C0.3 B0.01 T0
G80

This code works 90% of the time but then will suddenly stick on 0.75 feed, whereas when it runs properly it goes to 0.75 feed when at the point of starting the thread and then changes to 600 feed when cutting the thread.

thanks

Thanks - will do.

Quick couple of question though:-

1) Why G90 after G20 when you already have G90 in the top line?

2) Again why G80 after G83?

thanks again

Thanks for the info - I sort of gathered that but when I add L5 in absolute mode the operation does not repeat 5 times. I completes once and stops.

thanks again

The manual states:

10.7.22.4  G83  and G83.1 Cycles 
The G83 cycle (often called peck drilling) and G83.1 (rapid peck drilling) is intended for
deep drilling or milling with chip breaking. See also G73. The retracts in this cycle clear the
hole of chips and cut off any long stringers (which are common when drilling in aluminum).
This cycle takes a Q number which distance used by each peck. Program 
  G83 X~ Z~ R~ L~ Q~ 
Preliminary motion, as described above. 
Move the Z-axis only at the current feed rate downward by delta or to the Z position,
whichever is less deep. 
For G83 rapid back out to the clear Z. For G83.1 rapid out by the peck distance (Q)
Rapid back down to the current hole bottom, backed off a bit. 
Repeat steps 1, 2, and 3 until the Z position is reached at step 1. 
Retract the Z-axis at traverse rate to clear Z. 
It is an error if: 
·  the Q number is negative or zero.

L - number of repetitions in canned cycles/subroutines key used with G10

However I can't see what "L" is for? I have tried it and it seems to do nothing (tried several different numbers).

Is it relevant?

thanks

That also swaps the keyboard jog and everything else. Just need the shuttle to swap axis.

thanks

Not interested in making money, just wanted to see if I could swap the x axis direction.
