General Mach Discussion / Condition testing in Gcode

« on: April 12, 2016, 03:32:15 AM »

Hi Guys,

I need your help again. I'm really not all that good with gcode, nor with Mach3 beyond the basic stuff, so I hope somebody has an easy solution to the problem I have.

I have made the coordinate table for the battery spot welding machine. Basically you put a bunch of the batteries on the table and fasten them, and run the gcode, most often the simple X-Y array, so the batteries are welded into a pack. No problems there, quite a simple task even for me. The welder's head has two electrodes and is driven down and up again by the pneumatic cylinder. I've hooked the switch to the relays on the BOB and use the coolant command to start the cycle, and a dwell command to give it time to do it's thing. Most of the time, everything work flawlessly, but sometimes the electrodes stick to the battery contacts, and the problem has to be resolved before the next move, if not, the electrodes will bend rather than unstick, the position is lost etc...

So I have added the switch at the head top position and need to test if it's on before the next move is made. Simple enough, except I don't know how to do it;)

I hope the above is clear enough, and that somebody can help me with this. Is there any command in Gcode I can use for this, or any setting in MACH3 which wouold do this?

Thanks in advance

General Mach Discussion / MPG

« on: January 26, 2016, 10:33:10 AM »

Hi guys,

I'd like to ask for your help. I've been trying to connect the handwheel (see image) to MACH3 and use it for jogging, without success so far. I have searched for information here on forum and on the web, only to get even more confused.

My question is, is it at all possible to connect and setup this handwheel without having second LPT port, modbus card, some special plugins etc.?

What I did is connect the handwheel's Vcc, GND, A(pin 13) nd B(pin15) to my BOB, and setup an MPG#1 as on the attached setup image. I guess I was overly optimistic, and I'm more than probably missing something, so I'd be thankful for any help.

I also wanted to ask if there's any option to select the axis for jogging via BOB terminals and if so, how to setup this?

If this has to do some other way, I'd also be grateful to some links to the information how exactly it should be done.

Best,

Miso

VB and the development of wizards / Need some help - punch press wizard?

« on: March 11, 2012, 04:43:44 PM »

Hi everyone,
I hope this is the right place to post my question.
I have made two axes for the old punch press my friend uses to punch the holes in aluminum plates.
As he is not very skilled with computers, I'd like to provide the simplest solution possible for him. So I'm interested if there is some sort of wizard that I could use, or is it possible to customize an existing one (like rectangular hole pattern for instance)?
The same tool is used for all the work, only the number of holes and distances in x and y directions change. Unfortunately, I don't have any experience with the development of wizards, so I'd appreciate any help or advice.
Thanks in advance.
