General Mach Discussion / Re: Feed Hold problem

Yeah, I've tried it with several files and I get the same result...

Thanks for checking this out. I'll forward the question to Tom at Candcnc and see what he thinks...

Thanks for the quick response.

Cheers,

Yeah, I should have thought of that...

General Mach Discussion / Feed Hold problem

« on: March 17, 2009, 02:24:49 PM »

I recently installed Mach3 with the Candcnc breakout board to an old Dyna 2800 mill. Using the Sherline mode, it seems to run fine with the original Dyna steppers and drivers (much to my amazement, I might add!).

The only thing that isn't working (so far!) is the Feed Hold button. When I hit the button on the screen during program execution, I get the "Note: Cycle pause in effect.. No jogging or Reverse!!" message in the status box, but the program continues to run normally.

The "Stop" buttons works perfectly.

Is there something I could have overlooked in the set up that would cause this?

Thanks,

General Mach Discussion / Re: Mach3 and video card

« on: February 08, 2009, 01:58:48 PM »

I used Mach2/3 on an IBM PC/XP with integrated graphics for about a year and half without major problems. I did, however, get occasional (perhaps every 10-15 hours of operation) Limit Switch stops for no apparent reason. Changing the debounce setting up to 2500 didn't seem to make any difference. I thought that this wiring related, and didn't  do much about it because for the hobby stuff I do, it wasn't that much of a problem.

I came across an old Cirrus Logic video card in my pile of PC related junk, and decided to install it (XP makes it pretty easy to disable the integrated graphics and run the video off the card). I've been running this for about 4 months without any Limit Switch stops with the debounce set at 500...

I wish I could be a little more quantitative about this whole thing, but I'm thinking that the limit switch stops were caused by the well known integrated graphics problems, and disabling the integrated graphics and installing the video card solved the problem...

Sorry I didn't read your original post earlier.

When I get serious about upgrading my Dyna, I'll probably try to get your advice on some of the details of your upgrade . (Right now I'm planning to replace the original drivers with Geckos, install direct drive steppers, and try to keep the spindle speed/mag brake controls intact...)

mikreg53549:

Yeah, I've got a 2800 (currently running under Artisan Software's "AHHA", but hopefully soon to be converted to Mach3). I've been running it for a couple of years, and its been a good machine.

I have most of the original manuals (original software user guides, electrical diagrams, parts lists, and some mechanical/maintenence details). What all do you want copies of?

General Mach Discussion / Re: Set Z to zero automatically?Auto tool zero questions

Thanks to Scott and especially Greg's help, the probe is working perfectly.

On Bob Campbell's breakout board, if you connect and assign the probe to the Aux Home pin(15), enable both the probe and 4th axis home on pin 15  in Ports & Pins, and it works perfectly...

As usual, it wasn't a hardware problem - it was the lousy software between my ears.

Thanks

Scott,

Thanks for the the clarification. On my diagnostic screen, the 4th LED on the top row is the one that toggles on and off as the probe is grounded.

I think I've found the problem. A careful rereading of my BOB documentation suggests that the four aux inputs aren't independent inputs, but are only intended to be used as limit switches. Each input is apparently hardwired on the board with the home/limit switch for one of the axes...

I've sent an e-mail to Campbell Designs for clarification, and the response was that they'll look into it and get back to me. I await their reply...

Thanks for your help,

SF

Scott,

Thanks for the suggestion. I've tried that, and grounding has no effect.

As I'm trying to verify the entire signal path from pad/probe to the Mach 3 screen button, it has become painfully clear that I still don't understand how the button on the screen is linked to pin assigned in "ports & pins". I assume that much of this magic is contained in the OEM code, but the link between the screen button (and its macro) and the assigned pin still escapes me...

Thanks,

SF

Scott,

No, when I ground the pad while the z axis is traveling down, the motion doesn't stop (i.e., it doesn't terminate the macro).

I beginning to suspect that I don't have the correct mapping for the BOB's internal pin/terminal connection, although I've made the probe connection to match the documentation I have for Sound Logic PC-2-Route Model M2 board. Tomorrow, I'll try using a different terminal on the BOB and see what happens.

I really appreciate the responses-getting advice quickly from you guys keeps me from getting frustrated.
