Sieg KX3 and 5i25. Seeking firmware.

I'll try that

Other than the HAL file, what else needs to be created? (.ini?) or is that the only one?

Pncconf will create a config which is approximately right. The INI file should be OK, but the HAL file will need a few changes.

OK so back at it.
Removed everything and starting from scratch

Launch PNCconf and create a new config

Went through a couple of tries and can't find where to pretend I'm using a G540.

Tried PNCconf edit existing config but there are no configs anywhere I can find.

Tried copy the G540 ini, hal and xml files into the config dir and using the LinuxCNC config picker app, selected the g540 and after a few seconds it gives an error
hm2_5i25.0.pet.watchdog not found ./hm2_g540-stepper.hal:52 addf failed

Spent an hour at lunch going through the wiki pages.... I'm just so completely lost
Arrrgggg

Forgot that pncconf doesnt have a g5450 config, try probrfx2 (as similar parallel port like config)

OK, maybe slight progress

Created a new config using probrfx2
attempted to set some things knowing I'll have to fix the HAL

saved the config and tried running linuxcnc
error on a bunch of spindle stuff so I opened the HAL and commented out the offending lines, re-ran, re-commented out new lines all related to spindle. had to open the mitsub HAL and comment it out also
Finally linuxcnc loaded without error

Nothing works other than I can reset the estop I guess it is but it's only the program not the machine of course.

Anyway, it ran the program.
Now, looking at the HAL I'm thinking I should try to get just one anything working like a single axis to move,
The estop on the machine is on pin 10 active low
HAL has

# ---estop signals---

net estop-out <= iocontrol.0.user-enable-out
net estop-out => iocontrol.0.emc-enable-in

Yaeh that doesn't sound promising

I needed the charge pump as well

HAL has
loadrt charge_pump
=addf charge-pump servo-thread

and later on has
# --- CHARGE-PUMP ---
setp hm2_5i25.0.gpio.017.is_output true
net charge-pump hm2_5i25.0.gpio.017.out

My chargpump in mach3 is pin 17 so I'm hoping this is vaguely correct

for the X-Axis

HAL has a tonne of stuff

very little of that looks familiar
I've got X-drive step on pin 6, dir on pin 5, dirlow-active true steplow active

You probably don't want chargepump at all. There is a stepgen on pin 17 (I think) and what you need to do is set that running at a constant rate.

This involves setting it to velocity mode, then setting a suitable step rate to put it at the right frequency for the charge pump.

The information you need it all here, but I will not pretend that it is written in an approachable way:
linuxcnc.org/docs/2.7/html/man/man9/hostmot2.9.html#stepgen

Actually, just so we are not talking at crossed-purposes, what is the actual pin layout of your firmware?

I get that it sees 34 pins but which of the above pin callouts is what I would think of as the pin?
As in pin 17, the first group says
17 7 IOPort StepGen 5 Step/Table1 (Out)
while the second says
17 24 IOPort StepGen 11 Step/Table1 (Out)
or does it matter?

M

The hal file will refer to the GPIO number ( the second column ) for I/O

The stepgens will be referred to by the stepgen number
so for example you can see from the pinout that:

stepgen0 = X
stepgen1 = Y
stepgen2 = Z
stepgen3 = A
stepgen4 = Spindle control
stepgen5 = Charge Pump

Hard to believe I could be more lost than I was.
ok. So on the HAL snipet I posted earlier

Under the X-axis section I've got lines like

setp hm2_5i25.0.stepgen.01.dirsetup [AXIS_0]DIRSETUP
setp hm2_5i25.0.stepgen.01.dirsetup [AXIS_0]DIRSETUP
setp hm2_5i25.0.stepgen.01.dirhold [AXIS_0]DIRHOLD
setp hm2_5i25.0.stepgen.01.steplen [AXIS_0]STEPLEN
setp hm2_5i25.0.stepgen.01.stepspace [AXIS_0]STEPSPACE
setp hm2_5i25.0.stepgen.01.position-scale [AXIS_0]STEP_SCALE
setp hm2_5i25.0.stepgen.01.step_type 0
setp hm2_5i25.0.stepgen.01.control-type 1
setp hm2_5i25.0.stepgen.01.maxaccel [AXIS_0]STEPGEN_MAXACCEL
setp hm2_5i25.0.stepgen.01.maxvel [AXIS_0]STEPGEN_MAXVEL
etc.

So that's stepgen1 (stepgen.01) or is it stepgen0 (5i25.0.) ?

And on my mesa file output (posted above)

4 6 IOPort StepGen 1 Step/Table1 (Out)
5 8 IOPort StepGen 1 Dir/Table2 (Out)

So my Pin for X Step is 4 and the Dir is pin 5

???

Not questioning but is there any reason for not using the charge pump feature? I was reading and it looked like I could set the 12.5khz the c11g card wanted by setting the base-thread = 40,000 in the ini file

Using the HAL
freq = 12500
?
