Need Help!- Adding Another PP

[M250cnc]

I followed the instructions from http://www.linuxcnc.org/docview/html...llel_port.html

I put this in the custom hal file so it not over written

When i then try to start i get an error dump file

I am obviously not sure what i am doing wrong this is the the info i get when i run lspci -v

Can anyone help me use the correct port in the correct format

Thanks

You need to post the error.
also what version of emc are you using and are you using stepconf.
the current stepconf can add a second and third parallel port just by entering the addrerss
and checking them to load.

I/O ports at bc00 [size=8]
I/O ports at b800 [size=8]
The parallel port is most likely at one of these addresses. But, NetMos chips are a little odd, so it is possible these addresses reported by the PCI enumeration could be wrong. You will have to try both of these addresses to find out which one is connected to the port you are using. (The other address is likely connected to a 26 pin header on the board, which you can connect another 25-pin D connector to.

chester88, jmelson,

Thanks, i tried entering the parport in stepconf with both b800 and bc00 i am using EMC2 ver 2.3.5

Both loaded OK, is there a simple test to check that the port is correct i am not using the port at the moment, it is for an MPG

I want to make 100% sure everything is working before i leave Mach3, in Mach i use a USB device (Shuttle Pro)

Sorry for the dumb questions

[chester88]

The best way is to test it!

wire a switch to one of the inputs and watch that pin with halmeter.
halmeter can be loaded from the AXIS screen.
search the pin names for the parport.1. whatever pin your checking.
The fact it didn't crash with error is a good sign. There is probably two ports on your addon card as Jnelson said.

One a side note you can probably use your Shuttle pro with emc.
though it is fairly involved. You might want to try it later.
look here:
http://hidcomp.sourceforge.net/#hidcompcontrols

It mentions the Shuttle pro.

chester88 thanks for the reply,

I hope you guys can appreciate i am on a steep leaning curve.

chester88 I checked the link you gave me and that is too steep for my old brain.

I already have a dedicated MPG, i absolutely hate the shuttle pro for various reasons.

I would like some info on the PoKeys device if there is any. Mainly keyboard emulation, which the PoKeys is very good at.

Don't put it into the custom.hal file

the problem is the line
loadrt hal_parport cfg="0x0378 0xbc00 0xb400 "

in the form 0x378 is already in your
machinename.hal file

and hal gives an error that you have already loaded the parport driver.

EMC2 user manual needs update-ing to mention that you can only do things like this once.

Took me awhile to realise this.
eg. I loaded it in the command line version of Hal, then I couldn't load emc2 even with standard 1 port.

My question is how do you setup the axis(s) once you have loaded all three port adresss... you still need to do....

addf parport.0.read base-thread
addf stepgen.make-pulses base-thread
addf parport.0.write base-thread
addf parport.0.reset base-thread

etc for every axis on the particular port. I am still struggling with this.

Erlyrisa:

Why don't you use stepconf ? It will set up the three parports for you after you add the addresses.
Hmm unless you are trying to have one axis per parport.
While it maybe possible I wouldn't recommend it.
Leave all the axis step signals on the first parport and use the other parports for
extra I/O.

What are you actually trying to do?

I'm hoping to build a multi axis machine - on the order of 5+

I had a look at the example 5axis.conf but that's not setup for step outputs just simulation.

It's probably not hard todo, just wish thier were more in the manual about things like this, it seems the manual is geared toward starters, and the hard stuff is left for the uber geeks to figure out.

--A fix on my last post - what I meant to say is that the hal_parport line is already in your machinename.hal file ... putting it into custom.hal just doubles it up and doesn't work - in other words the manual and similar posts have this wrong.

Putting 0x37 0xbc00 etc in the step config wizard didn't work for me.

What version of EMC are you using?
Can you elaborate y loading the parport in stepconf didn't work.
error message?
Description of what you expected and what you got.

Thanks

I must have been puttin commas in - It does work...

I simply put 0x0378 0xbc00 0xb400 into the stepconf wixard and it change my cfg="0x0378 0xbc00 0xb400 out "

It also setup the pins, of course stepconf didn't ask about doing more complex axis ... will have to do that manually I guess.

[chester88]

Yes stepconf was built for simple desktop machines, but by looking at the ini and HAL file plus 5 axis config files you should be able to get close.

Glad you got it working.
