it be interesting to install pendant to it
What kind of pendant, and what kind of interface? Joystick, MPG? USB, parallel port? How many pins required to interface the functions of the pendant to the controller?
Mark
I am using MPG type pendant. My machine based on EMC2 software and it is working as you can see on web AMTB
base information here EMC Documentation Wiki: EmcKnowledgeBase
and here
EMC Documentation Wiki: Hooking Up A MPG Pendant
also here

i do not know very good coding so i can not install my mpg pendant to my emc2 machine.
i couldn't get help from EMC2 list that i can use so , pendant is not joint to my machine
Thanks
Aram
Okay, so it's an MPG. is it a home-made MPG, or one commercially available? I've got both an MPG pendant and a joypad hooked up to my machine (likewise running EMC2). I bought my MPG and adapter from Keling the MPG3 and C22 adapter:
Services - look down towards the bottom of the page.
I didn't need to do any coding to make the MPG work, other than enabling the second parallel port and editing the ini file so that it recognized the custom.hal file. I used the code from this site (slightly edited because I only have a two axis machine, X and Z) and cut and pasted into the custom.hal file:

hi
I bought my MPG from PC for CNC Autol Dunkan. It is similar business to Kelling.
MPG home made or manufactured is same. MPG is a box where JOG wheel with A-A B-B and +5 and ground. Also switches XYZ ans increment switch.
I am using EMC2 machine and i think to plug in MPG to EMC2 machine need code.
Do you use EMC2 software to run your machine?
LinuxCNC.org - Home ???
Aram,
Did you read any of what I wrote or click on the links I gave? It pretty much spells out everything you need to do to connect the pendant to the PC and it gives you all the code you need to make the pendant work with EMC2. Not sure what other help I can give you. And I even said in the reply that I use EMC2.
Mark
Hi Mark.
Thanks for helping me.
I have pendant MPG-3 and I think that you using MPG-2 pendant. My pendant MPG-3 also came with C22 PENDANT interface card. My C22 looks different that on photo that you referring, my C22 card has cord with USB connector on the end and no terminals with screw. I think those deferens should make any problem.
When I bought my pendant, that is MPG4 , I found that some wires aren’t connected to switch – XYZ - or Increment selectors -0.0001- 0.001-0.01.
So I rewired my pendant. Actually rewiring of pendant did John Elson on CNC work shop Cardinal Engineering in year 2007.
Here these a pins from my pendant
1. VCC
2. ---------
3. A (jog wheel)
4. B (jog wheel)
5. x1 (increment)
6. x10 (increment)
7. x100 (increment)
8. Z axis
9. Y axis
10. X axis
11. 4(Aaxis)
12. 5(Baxis)
13. -------
14. COM (ground) for switches and + for OV on JOG wheel.
15. Estop
16. Estop
17. ---
18. ---
19. ----
20. ----
21. ----
22. ----
23. ---
24. B -- (jog wheel)
25. A – (jog wheel)

My jog wheel from MPG-3 has A A- B B- and +5 V and ground. I know that some
MPG-2 comes with jog wheel that only has A B +5 and Ground.
How your code should change to accommodate extra 2 pins from jog wheel?
Is it --- quadture signal per click set x4 to 1-----?
But I need physical 2 more pins to join A- and B-. Am I right?
When you said -----“other than enabling the second parallel port and editing the ini file so that it recognized the custom.hal file.” -----
1. How you do enable second parallel port? Did you write some code? How to do that?
2. What you put into INI file to it can recognize custom.hal file?
Thank you, for helping me out
Aram
Aram,
I have the MP3 pendant from keling. I don't have my files here at work and since you've changed the wiring pinouts on the pendant, it'll take me a little more work at figuring out how yours needs to be set up.
As for enabling the second parport, that's posted in the wiki:
1. Figure out the address of your parallel port card
To find the address of your parallel port card in a terminal window
lspci -v
You will see something similar to this
0000:00:10.0 Communication controller: NetMos Technology PCI 1 port parallel adapter (rev 01)
Subsystem: LSI Logic / Symbios Logic: Unknown device 0010
Flags: medium devsel, IRQ 11
I/O ports at a800 [size=8]
I/O ports at ac00 [size=8]
I/O ports at b000 [size=8]
I/O ports at b400 [size=8]
I/O ports at b800 [size=8]
I/O ports at bc00 [size=16]
In my case the address was the first one so I changed my .hal file from
loadrt hal_parport cfg=0x378
to
loadrt hal_parport cfg="0x378 0xa800 in"
note the double quotes surrounding the addresses.
and added
addf parport.1.read base-thread
addf parport.1.write base-thread
so the parport will get read and written to.
Your second parport address may not be the same as listed in the example above, so you need to find out what it is.
By the way, if you look at the first line of the wiki page, it is for hooking up an MPG3 with the C22 interface.
As for the entry in your ini file so it recognizes the custom.hal file, or whatever you want to call the file, it goes under the [HAL] section:
[HAL]
HALFILE = custom.hal
Mark
Hi
Mark
I did edit code. What do you think about it?
Do you know where i can get help with code for C22 card?
I still can not see in your code how you connect increment switch 0.01 0.001 0.0001 ? there should be pin-??-in something similar.

hi
i found this wiring of mpg3 pendant -http://www.markusmechatronics.com/HandradAnschluss.jpg
diagram shows that increment switch should have 3 pins for 0.01 0.001 and 0.0001
it described not for emc2 but i think wiring should be same
Am i right?
Thanks
Aram
That's the wiring diagram I used when I added my MPG to the machine. Looking at my hal file, the A- and B- are not used and according to the wiring diagrams (both yours and mine) they are only used for line driver output. Here's my custom_postgui_pendant.hal file:

Note: I've turned off any pins that go higher than XYZ on my pendant, since I don't use them. And I'm not using the quadrature type signaling, but rather the pulse signaling. Also, some pins may not agree with yours, since you re-wired your pendant. You'll have open up the halshow in Axis to find out exactly what pins are being read.

Hi Mark
In PIN i can see that you using Pin for X Y Z A axis -4 5 6 7- and for jog wheel pin 2 and 3.
Question: how increment switch communicate to computer if it (switch) doesn't have any pin?
Is there OEM address for manufacture of C22 adapter to ask question about pins?
Who sold C22 - distributor.
thanks
Aram

Note: You're going to have to translate some pins on the C22 because you re-wired your pendant.

Hi,
I made some modifications to the file EMC Documentation Wiki: Parallel Port Tester
Zip file attachment, containing the hal and xml, plus a pdf with the explanation.
With this test I added at the end of file hal.
the contents of the file "Adding_to_end_hal_file.txt"
and works perfectly
best regards
Narciso
