As long as the axis is only controlled by gcode (with no direct display/control from the GUI)
it should work.

You will have to do some hand editing of the hal file to add
the additional joints/axis and kinematics specifier.

Here is a suggestion:

( pncconf has more built-in QTPlasmaC/THCAD support  so may be an easier path)

If I hadn't already occupied all 5 axes I wouldn't have a problem.
Is it possible that my 7i85s card can't control any motors? Does this only work with the 7i85 (without S)? I can't find a clear answer online. Thanks.

At the moment i am testing with hal pins, because of the option 'start from current position' . To have the correct preview, it only worked with hal. The loaded file is just a translation file to call the subroutine. (The subroutine can be used standalone, in gcode or like here from the ui) It is working, i just have to rmember to reload, when parameter changed. Still pending, set a parameter eg  #<_RUNONCE> , which allows the routine to run only once, then have to start from  the panel with known parameter for further use. What i have done so far is mostly working as desired. The sidepanel is a stacked widget with 16 layers when completed

 
 

Can linuxcnc used as controller for hydraulic injection molding machine ?
For example to read thermocouples and do pid temperature control
actuate hydraulic solenoids read linear scales encoders and pressure sensors.
Does anyone have done retrofit of injection molding machine with linuxcnc ?
A machine that is not gcode controlled and not have linear axes..

Hostmot2 firmware is there. Running Axis in a VM using the sample code, apart from the latency error, runs ok.

Now this is something I found rater curious.
Both were builds had the target as Debian Bookworm.

Building on a system running Debian Trixie raspi-firmware IS NOT installed. (built twice on 2 different machines)
Building on a system running Debian Bookworm raspi-firmware IS installed. (single build only attempted)

I will try a build on my Bookworm machine with the live-build package from Trixie and see what the results are.

The firmware "blacklist" is created here
salsa.debian.org/live-team/live-build/-/...h?ref_type=heads#L92

So I will need to see what the difference is between the Bookworm live-bulid package and Trixie.
Simple enough Bookworm doesn't have the firmware blacklist code.

Says:

Spindle orientation requires a quadrature encoder with an index to sense the spindle shaft position and direction of rotation.

The need for an encoder can be worked around by using a StepGen with the index feature but that would still require
a once per turn signal for initial alignment.

Hello, I use QtDragon with 5 axes (X, Y, Z, B, C) and have expanded and flashed my Mesa 7i76EU with a 7I85s. The additional 4 axes are also displayed with sudo mesaflash --device 7i76eu --addr 192.168.1.121 --readhmid. As far as I know, QtDragon can only handle 5 axes. I need an additional axis for the ATC that doesn't need to be displayed in QtDragon. Can I control it via G-code, e.g., G0 W100, or if G-code isn't possible, via HAL commands?

I read that you can customize the xyzbc-trt-kins file, but I can't find it?

I am trying to use the M19 command:

m19 r90 q10 p1 $0

The m3 & m4 commands work as expected, but m19 does not.  Any guidance would be greatly appreciated.

My HAL and INI files are attached (Spindle0.inc renamed to be Spindle.inc.ini so that it could be attached).

If you use partial and pass the parent then you have access to everything.

There is a #flex-dev channel on the Libera.Chat which I monitor usually.

Unfortunately, I'm still stuck, even with the additional link.
My thoughts:
Where can I get the spindle speed (float)? Would that be the value “spindle.0.speed-out,” for example, which can be seen in the attachment?
How do I transfer the float value to gladevcp.Spindel?

My favorite code doesn't work. Error "custom_postgui.hal:9: Pin 'spindle.0.speed-out' was already linked to signal 'spindle.0.speed-out'"
 

OK, I've managed to get the motor moving. The two +/- buttons now move the motor, although I'd like to have an interface with arrows. (More user-friendly)

I'm using the default LinuxCNC configuration for my 7I96S card. I need to modify the parameters for my CNC machine. How can I do this to ensure that the changes are correct?



Thank you.

Can you post the complete hal  file so that cause of the issue can be determined?

Pretty sure mine does not use M68, but M67.
The included dmap2gcode can open an image and output gcode you can test with, it creates a depth map of the image so it also varies the laser PWM as needed.
You can use my config as is, but:
-you have to edit the hal file parallel port pins for your hardware
-maybe also edit the ini file velocities and accelerations for your machine as mine are set very high on acceleration and slow for velocity
-it also has a PyVCP panel that shows the PWM/laser power
-my config is alos limited to roughly 80% of max PWM to prevent pressure servo motor from triggering protection, you do not need that so you can push 100%.
