Changes in configuration files generated in pncconfig for 7i76 to 7i78

Category: Configuration Tools

I suggested the G540 configuration because it includes  PWM generator that you can use
with pncconf for setting up the the spindle, the 7I76 configuration does not.

On the halcmd, yes you need the driver loaded, as I mentioned:

Note that you can list all pin and parameter names when LinuxCNC is running with:

ENCA+, ENCA-, ENCB+, ENCB-, IDX+, IDX- are all physical signal names and are not present in hal

encoder hal pins and parameters will all have names like:

hm2_7c81.0.encoder.00.position
hm2_7c81.0.encoder.00.index-enable
 etc etc

Where  the 00 in hm2_7c81.0.encoder.00.position is the encoder number

with 7C81 7i78X2d or 7I78x3d firmware, encoder 0 would be on P1

If you want to use encoder 0 on P1 for the spindle encoder, you select encoder 0
as spindle encoder  in pncconf. Similarly PWMgen 0 is on P1 with the 7I78 firmware
so pwmgen 0 would be selected for spindle speed control.

What handle?

A picture of the machine would be nice.

What about arrow keys and PgUp/PgDn

French characters appear very broken in the HAL and INI files, someone needs to fix that.

Indeed, there was an error; I had given the threads "scale" names, and that's why it was giving that error. I'm resending the corrected file.

ADm1N didn't use CSV mode, it doesn't work well for a spindle as you see.
He used PV Profile Velocity mode which works well for spindle.
I made an adaptation to cia402 component for pv mode here incl an example

The command you recommended wrote this:
halcmd show all hm2
Loaded HAL Components:
ID Type Name PID State

Component Pins:
Owner Type Dir Value Name

Pin Aliases:
Alias Original Name

Signals:
Type Value Name (linked to)

Parameters:
Owner Type Dir Value Name

Parameter Aliases:
Alias Original Name

Exported Functions:
Owner CodeAddr Arg FP Users Name

Realtime Threads:
Period FP Name ( Time, Max-Time )

This works:
halcmd -kf
halcmd: loadrt hostmot2
halcmd: loadrt hm2_rpspi
halcmd: show all hm2

A quick update here! I got my 7I92TM and 7I76U today, and after some swearing at Linux networking I got them flashed and confirmed working via halscope. Thanks all for getting me to this point, I need to request an RMA for the other card as well and get them in the mail.

Thanks again to everyone who's gotten me here. Now that I've got this sorted out and am confident I understand a bit more about Mesa / Hal / etc, I'm going to build out the wiring diagram, which I'll put in my other thread.  

Thanks!

You can also disable motion by setting 'motion.enable' to FALSE but machine state will still be switched to Off.

the relevant code section is here:
github.com/LinuxCNC/linuxcnc/blob/master...tion/control.c#L1465

If it is possible to do this for a specific joint during program execution would have to be explored. I expect that the interpreter would need to restarted at the very least.

No, I added my pins and linked them to jog_increments widget:
[code][code]pin = QHAL.newpin("mpg.mpg-inc.1", QHAL.HAL_BIT, QHAL.HAL_IN)
pin.value_changed.connect(lambda s: self.w.jogincrements_linear.setCurrentIndex(1))
pin = QHAL.newpin("mpg.mpg-inc.2", QHAL.HAL_BIT, QHAL.HAL_IN)
pin.value_changed.connect(lambda s: self.w.jogincrements_linear.setCurrentIndex(2))
pin = QHAL.newpin("mpg.mpg-inc.3", QHAL.HAL_BIT, QHAL.HAL_IN)
pin.value_changed.connect(lambda s: self.w.jogincrements_linear.setCurrentIndex(3))
pin = QHAL.newpin("mpg.mpg-inc.cont", QHAL.HAL_BIT, QHAL.HAL_IN)
pin.value_changed.connect(lambda s: self.w.jogincrements_linear.setCurrentIndex(0))


[code][code][code]But I would like to be able to enable/disable the increment selection from the screen, only showing the current value. Perhaps there is a way to disable the drop-down menu or something like that.

Thanks for the answer. There is one 7i78 -> P1 connected to 7c81, one optocoupler board on P7 and when I know how to do it, one 7i73. Why not pncconf for 7i76 but G540? It's more similar to 7i78. So with that encoder it means that it doesn't matter where and what encoder I choose, just change the name in .hal according to your example? Sorry for the question, will it be clear that it is a spindle encoder? Although it may be a stupid question, 7i78 has only one encoder and it is for the spindle... In the manual for 7c81 the encoder is marked as ENCA+, ENCA-, ENCB+, ENCB-, IDX+, IDX-. I don't know how it will look in .hal, because pncconf does not have the option to configure the 7c81 board. Well, with the list of parameters, it's clear, but as I already wrote, I'm completely lost and it's going slowly :).

MPG and analog command config issue

Category: Basic Configuration

Hello I try to setup a mill with all servo drives run with analog command and it's working fine.

However, now I try to setup a MPG
after customizing the HAL file, here is the situation:
the MUX is correctly working for the scale and the axis.x.jog-scale is correct (value from 0.01 to 1mm)
axis.x.jog-enable works fine, same for Y and Z
axis.x.jog-counts works fine, I can see the number of pulses moving when I turn the handle
axis.x.jog-accel-fraction is set to 1

When using Axis interface with the and - button, it works fine
However; when I turn the handle, the axis is not moving at all, I don't have any error message.E-stop is off and Toggle Machine power if ON obviously. 

Any idea what could be the issue?
thank you
