General Mach Discussion / No movement with gcode

« on: November 19, 2012, 05:22:33 PM »

Hello all, I have had my machine running mach3 nearly flawlessly for almost 1 year!!! But I have noticed a problem that seems to be getting worst with time. Every once and a while when I go to my cord zero"G00 G54 X0 Y0" in MDI the machine wont move. I end up having to restart Mach3, then rehome and all works fine. I get no errors, following or others. I can jog the axis with the arrow keys and MPG, but when I type in MDI it wont move.

I have DC servos motors with the DSPMC controller from Vital Systems.

Please help if you can!

Thanks,

Aero

General Mach Discussion / CV Mode turns off by its self

« on: June 02, 2012, 11:27:10 AM »

Hello all, I have a problem with my CV Mode turning off on its own and I can't get it back on unless I relaunch Mach3. Not sure why it does this. It's not a big problem, just pauses around arcs.


Any help would be great

P.S. It's not in the program, since I can run the same program for days, then all of a sudden it does it (turns CV Mode off).

OK, I tested it in MDI and works GREAT!! Later I need to work on the repeat the pattern in different places part. But this will make this job ALOT easier!!


Thanks so much BR549!!!!

OK, say I do this:

Mcode M153:

NextPos = Question(“Enter next B position:”)

Mcode M154:

Code “G00 G54 B" & NextPos


Gcode:

N1 G00 G40 G80 G90
T01 M06 (3/16 2 FLUTE CRB EM)
S3200 M03
M153
M154

Can I repeat M154 and the value will still be the same? Does the Var "NextPos" keep it's value?

Hello all. I have a program I run that uses two cutters. The program is a pattern that is repeated multi times on the same part. I have a VMC with an extra table that extends the X-axis, with a servo (I use the B-axis to control it). The pattern stays the same on all parts but the location on the part changes (B-axis). I need to figure out a way to have Mach3 bring up a popup menu that ask what the B-axis value needs to be then moves to that location and runs the pattern.

The parts are various lengths, so some have 1 pattern up to 10 patterns. Is there a way to make Mach3 ask how many locations for the pattern?

What would be nice is for Mach3 to prompt for the amount of patterns, then ask for each B value for each pattern. This might be asking for to much but this isn't going to be a one part run. I will be making these for years (hopefully).

Here is the program:

N1 G00 G40 G80 G90

G00 G54 B0 X0 Y0       (This is the B value I need to change)

General Mach Discussion / Re: Installing a new axis to our VMC and have some questions

« on: January 30, 2012, 04:39:42 PM »

So I just uncheck the (axis) Home under ports and pins. Then check Auto Zero under Homing/Limits?
Seems to work, I just wanted to make sure.


Thanks,

General Mach Discussion / Installing a new axis to our VMC and have some questions

« on: January 23, 2012, 12:42:55 PM »

We are adding an axis to our VMC to accommodate for machining a long part we are making. I have a couple questions to help this project come together smoothly.

Question #1: The table extends passed the side doors of the machine, which will make homing the machine impossible without cutting out a section of the door frame. I have Mach3 home to home switches then back off to the index on the encoder. Is there a way I can set Mach3 to home the machine where it sits when I start it in the morning? I know I will have to touch off my offsets and tools, but if it would save modifying the machine I would like to try that first.

Question #2: I'm getting ready to buy the limit switches for this axis. Can I get away with one limit switch in the middle of the table and wire it to the +/- for that axis? So one switch mounted to the main table and the activators on the new table on each side?

Anything else that you guys can see that might be a problem please let me know.

Thanks for the help
