General Mach Discussion / single block problems
« on: November 18, 2006, 10:36:32 PM »
 ???
I've been having problems when running a program, putting it into single block near the end of a contour, it has taken off. It did it with mach 2, now I'm running mach 3 v1.9.081.
Heres the program:

O0001(11-18)
 
(T1 =  .25 ENDMILL 2FL H1 , D1 )
 
N1
T1 M06 ( TOOL - 1  .25 ENDMILL 2FL   )
M01 (PUT T1 IN SPINDLE)
M08 G04 P1000
G54 G0 G90 X0. Y0. S6000 M03
(WATCH OFFSET ON OFF)
G43 H1 Z.1
G1 Z-.1 F8.
G41 D1 X-.011 Y-.0064
X.0127 Y-.0475
G3 X.19 Y0. I.0823 J.0475
X-.19 I-.19 J0.
X.19 I.19 J0.
X.0127 Y.0475 I-.095 J0.
G1 X-.011 Y.0064
G40 X0. Y0.
Z-.2
G41 D1 X-.011 Y-.0064
X.0127 Y-.0475
G3 X.19 Y0. I.0823 J.0475
X-.19 I-.19 J0.
X.19 I.19 J0. X.0127 Y.0475 I-.095 J0. **
G1 X-.011 Y.0064
G40 X0. Y0.
G0 Z.1 M09
M05
M30

It took off in the line ending with **
I had run it twice in single block mode and it worked fine. When I cut metal, it took off, see picture. After that happened, I was unable to recreate the problem.
What can be happening here? I've scrapped several parts by this happening. It's always an arc at the end of a contour when in single block. I like to put it into single block at the end of a contour when running for the first time to make sure of the retract, etc.

Anyone????
I'm wondering if I need a pullup resistor. The thing I don't get is why does it work on 3vdc from a battery but not 4.4 from the Hobby CNC board

Hi Brian,
My settings are Output 3, port 1, pin 17 & active high. I've also got the coolant set to output 3 on the spindle settings page. The LED  for pin 17 on the diagnostics page turns off and on & the wierd part is, I get 4.4 volts at pin 17, but it won't trigger the relay. The relay is good, it will trigger at 3VDC by hooking up 2 D cells.
I'm really confused, I've spent about 6 hours over the last week and no luck
Thank you for any ideas you might have

General Mach Discussion / setting up coolant pins
« on: September 21, 2006, 09:25:32 PM »
I'm having trouble setting up Mach 3(V 1.9.070) for my mist coolant. I'm using a Hobby CNC board and CNC4PC AC relay card. If I connect from the 5VDC pad on the Hobby CNC board it will work. I get pin 16 to switch on & off & get 4.4 volts there. My CNC4PC DC card for my spindle works at that voltage. I've tried different pins, switching active high/low and can't get it to work. Anybody got any ideas?

Thanks
Mark

under "config > state" there is a setting for persistant offsets. make sure this is checked

how do you enable enhanced pulsing. I have a problem where the drive stops working and I am wondering if this will help me. Can't find enhanced pulsing tho

Thanks
