Sieg KX3 and 5i25. Seeking firmware.

Actually going to take about an hour to get at the card (control box is behind the lathe and against the wall etc)

the lathe already has an index card tied to the C11G (C3) for the spindle speed and threading. The entire thing actually works quite well for the whatever amount of years I've been using it after the conversion and if I hadn't switched the Tormach mill over to pathpilot I probably wouldn't have even thought about touching the lathe.

Thx

LinuxCNC is better at threading than Mach3. Most other things are a matter of taste and opinion, but threading is significantly better because the Z axis is properly slaved to the spindle.
However, to see the full benefits you need more than one pulse per rev (and for rigid-tapping you need a full quadrature encoder so that the system knows at what point the spindle has reversed).

Before you go excavating for the card, why does your pin assignment differ from that in the manual? Are you sure it actually does?

I'll have to go back and look at my notes about the spindle. IIRC I have 8 slots on the disc and a single index slot for the timing but I have some vague recollection of having to add or block to get the threading to work correctly.

As for the pin outs, couldn't tell you why I picked those back when I converted this thing. Pin 14 and pin 17 were specified in the C11G manual and I guess I just picked others as I saw fit. Must have made sense at the time.

I got the pins it's using from the mach display screen (ports and pins) and checked them against the diagram I have in my book that I made when doing it. (board image with little notes scribbled on the various pins), again, must have made sense at the time.

Open a terminal window and type the following:

You should now have a live and working realtime system and powered-up Mesa card.
For reference you can make a list of all the Mesa card HAL pins:

Code:

show pin

And all the setting (parameters)

Code:

show param

It is probably a good idea to copy these pin and parameter lists into a text file for later reference.
All the entries you see in the HAL file part of your config are commands that you can use in the HAL environment that you are now in.

One very simple example:

Code:

setp hm2_5i25.0.CR01 1

should turn on an LED on the 5i25

Code:

setp hm2_5i25.0.CR01 0

will turn it off again.

When I type that in it gives "command not found" for any line. is there a specific dir I need to be in?

Did I forget the first "halrun" command?

If I did then start with halrun, and use exit to finish.

Yeah!!!!! that worked!
I had to add LED to he line for whatever reason but I see that in the pins
setp hm2_5i25.0.led.CR01 1

So for the first time something has happened that I wanted to

Now, lets say I want to turn on a single output pin, line an enabled signal just straight on/off?
I thought maybe setp hm2_5i25.0.gpio.01 1
but that would be too simple

If that is the pin name, that is exactly what you would do. Except that I think that GPIO-01 is allocated to stepgen.04.step. it should work for gpio.00 on physical pin 1 though.

You might also need:
setp hm2_5i25.0.gpio.00.is-output 1
(That will be in the parameter list, not the pin list).

The documentation for Hostmot2 is here, though it could do with some improvements in the formatting.
linuxcnc.org/docs/2.7/html/man/man9/hostmot2.9.html
You probably only care about the GPIO and stepgen sections.

Do you know what the desired frequency is for the charge-pump circuit on the C11G?

I'll try that (turning on a single pin) after work today
12.5khz for the chargepump

The HAL section for setting up the charge pump will look a bit like this.
You wouldn't type the comment lines when doing this by hand.

Watching this with great interest .The mesa HAL syntax is now much clearer.

#set the stepgen on pin 14 to velocity mode

The chargepump's on pin 17 (of the DB25) in the C11g.
