General Mach Discussion / Re: Can Mach3 do continuous loops?
« on: June 24, 2012, 12:01:21 PM »
or use a variable counter.

N10 #100 =1
N20 M98 O1 (RUN  SUB)
N30 IF [#100LT300] GOTO 20    (LOOPS SET TO 300 OR WHETEVER YOU NEED)
N40 M30

IN THE SUB INCREMENT COUNTER #100=[#100+1]

General Mach Discussion / Re: CV Mode turns off by its self

I've had this happen - often.

Instead of a restart, I edit the program headder when it happens to add G64.

Bit of a pain, but I live with it ;-)

General Mach Discussion / Re: How can I control a stepper motor for USB???
« on: February 19, 2012, 10:36:24 AM »
I need to program a pic 18f4550 to control a stepper motors, How can I control from MACH3?

Help me please. It is for the college thesis for my little brother!
Why do you want to control the steppers with a Pic AND Mach - that will be like an orchestra with two conductors ?

General Mach Discussion / Re: Switching from offsets (G54, G55... etc)

Hi Aero,

I'd write this way I don't know if it would make any difference to your problem, but I use work offsets all the time and I don't get the moves you are seeing.

G01 X-.03 Y-1.6355
G03 X-.23 Y-1.8355 I0 J-.2 F30.
G40 G01 X-.23 Y-2.1475
G00 Z1.
G55
G00 X.23 Y-2.1525
G00 Z.1

G01 Z-.385 F50.
G41 D01 X.23 Y-1.8405 F30

One would think streaming music in the background is a mindless task that Mach3 could handle as it does 95% of the time. It's that other 5% that bites ya! :)

Try programming an application to output a steady stream of pulses, while handling another such as decoding a MP3 file - firing that into a sound card and maybe other tasks. Its a bit like trying to sing a song and have a conversation with someone at the same time....it's no easy task..
One thing for sure is its amazing that Mach is working as well as it does for 95% of the time.

Mach3 PC on my mill only controlls the mill - I don't even use the ethernet port and it's not glitched in 2-3 years.
Industrial machine controls do one thing - control the machine for a good reason.

Save yourself a whole load of problems - broken tools, scrap parts and torn out hair - get another PC for the music and internet ;-)

I know; may be time to upgrade to WinCNC.
Or you could just buy a radio !

Hi,

The actual movement of the cross slide will be 1/2 the distance displayed in the X axis. (if you'r working in diameter)
but should move 1:1 in the Z axis.

General Mach Discussion / Re: Mach3 pendant
« on: October 30, 2011, 03:23:53 PM »
Hi,

I've been using the Contour ShuttlePRO for a couple of years.

Has the added advantage (over the pendant in your link) of having a central MPG wheel and the jog ring and using the Mach plugin, it can be configured to suit your application.
Ive bounced mine a few times, it's still working, but the key cap can ping off into corners of the 4th dimension (being clear they are hard to find !).

General Mach Discussion / Re: Mach3 crashes after File>Load Gcode command
« on: October 23, 2011, 03:45:28 AM »
I had mach crash on loding gcode.
I had a Q arguement set at 0.0
Once I edited the Gcode to say Q2.0 (peck drilling) it was OK.

Can you load a very simple file, for eg....%

Z20.0
M30
%

or does mach crash on loading every file?

Hi Hood,

Here is a photo of our VDI wedgie.
