I'm using Mach 3 and am finishing new pendant control for x,y,z with separate MPG's for each axis all in an inclosure.

Anyway I was wondering about suggestions for other functions that are commonly nice to have on a separate control. (like the e stop or something else)..

Should be cool once it's done. Was moving the table around spinning the dials last night and moving things around. So much nicer then dealing with keyboard jogging.

Not sure if I could make them cheep enough to make more for others though..

Cycle start
Pause

Ya for functions like that I guess I will be mutilating a keyboard eventually to do more functions..

Always fun to map out a keyboards matrix to figure which keys are which..hehe

Kinda wanted to avoide having a keyboard mother board in the pendant.. I think the answer to that is to put the keyboard mother board in my power supply and run the wires for the buttons back through the 25 pin cord (trying to avoide having 2 cords going to separate things out of the pendant.. Don' treally care of another cord goes from the power supply to the PC as those 2 don't move around...

You can use OEM triggers in Mach3 to use regular pushbutton switches for cycle stat and pause. Just wire to input pins and set up Mach3 accordingly.

Problem with that is a limit of imput pins. 2 inputs for each of the MPG's 10,11,12,13,15 already have caused me to have to add a second parallel port to support a dial for each axis. Leaves me with 15 free at the moment on one port..

The In/out put ports 14,16,17 are in/out but don't really do anything that I've been able to see.

[ger21]

Use a single MPG and a button to toggle between axis'. Or maybe 2, unless you have 3 hands.

Already have 3 dro's to use.. They were not to expencive.. Ebay # 180016645196

This guy was really great. Shipped fast and found me a 10:1 Thompson gear reducing head for my 4x8 mill project (to come).

Figured having 3 and not having to switch between them would be easier..

So far I have the 3 dro's.
1 button to disable all of them.
3 other buttons to disable each individually (don't want to move the wrong one by mistake.

Enable/disable direct to the gecko's

E stop to Mach3
Reset to mach 3

Probably will add some other ones.

Currently cutting the DB25 connector hole in the enclosure (using the newfangled wizard..)

And waiting for my old PC to return from my mother in laws so I can snatch it's old Parallel port card. CompUSA sucks.. Did not even have a single parallel port card in stock.. The nerve of them...

Should be cool to jog around..

Basicly give those HEDS on ebay 5v and connect A to one parallel input and B to the other and they work great. Little tuning to move the table the way you want but can't beat the price.. They are very nice units.

So you have already tried them and they work good. Maybe I'll pick some up and stash them away. Thanks.

[wcarrothers]

Yep.. They seem to work very well. They rotate smooth with a little resistance (so they aren't the tactile responce ones with detents) But I like that they are not tactile since they feel good the way they are. Quite heavy (shaft and all) Nicer then I expected.. I wish I could find some nicer dials then the ones I got from radio shack. Something with a finger hole or something to make rotation easier.

But simple to hook up. Give them 5v and plug the other 2 wires to parallel inputs and that was it.. I over complicated things with having disable switches and stuff but figure those will keep me from screwing things up when the thing gets bumped.

I probably have a little tuning to do so my speed and movement are right but they are nice and sensitive..

Cheepest way to do a pendant that I know of...

One other thing... I have a button wired into pin 15 of port 2 now that was suposed to be for triggering Mach3 reset. Got the button tied into the OEM inputs and can trigger things like changing from the main screen to say the setup screen but don't know how to tie that input to the reset button press (key ~ on my system toggles reset on and off)

Anyway...

Go to ports and pins, scroll down to OEM Triggers, set the port and pin, and click the hotkey column and hit the ~ key.

You may have to also go to the system hotkeys screen under Config menu and set the OEM code for the trigger your'e using to 1021.

[wcarrothers]

The 1021 in the OEM codes took care of it.. Sweet..

Although that button toggels between on line and off line so guess putting in the switch that triggers the estop (to do the same thing) was not really needed...

Oh well. Still learning..

Is there a list of those codes some where.. (don't tell me it's in the manual some where.. hehe I did actually print that..)

Thanks!!

Now I suppose the mill conversion is for the most part complete.. Seems to work pretty good. Although I wish my Z axis would have come out a little better.

I'll have to take some pictures..

Hi everyone,

i am new to pendant controls i have some i picked up from China but i
have not a clue how to wire them up into mach3 can anyone help.
These MPg`s have been arround a long time so i guess someone has sorted it for Mach.
www.hedss.com.cn/ehtml/products.asp

Model numbers ISMM2080 & ISMM1408

Anyones help would be appreciated.

I think for the most part with this thread you could piece together what inputs on the parallel port I have things connected to.

5V power to run them comes from the PC's power supply.

Mach does have setup for DRO's speed and calibration how ever I ended up inputting the values that made it work the smoothest on my own.

you may want to check out cnc4pc.com on this one. i hope i'm not blowing anyones cover, but these are the ones they sell. you could probably find the mach scripts etc,

Thanks for the information, i have just ordered some bits from cnc4pc today which i will probably get in a week ot two.
I have looked at their tech info and it looks as though i may get it sorted with their help. Got to get a second port into my pc now.

I have a cnc table router, x-3 cnc bench top mill, and a small cnc lathe the next item i am going to build is a 1/2 plate cnc plasma cutter. The pendant control will be used on all the machines.

Best wishes, thanks,
