I'm sure QtDragon has ATC funtionality, perhaps it's separate from the max number of axes?

A single parallel port can control 6 axes, so this is possible even with really old-school tech.

There has to be a solution; this can't be a new problem.

I would use AXIS at first; it's simple stable, and generally bug-free (except for the occasional regression).

AXIS is the best GUI for beginners IMO.

Try it out!

If you don't like it, then switch to QtPlasmaC.

Limit switches probably can't and shouldn't be disabled.

Do you need a limit switch there?

So long as the machine is homed, it won't exceed the soft limits unless the computer goes completely rogue.

Hard limits are preferable, but not always 100% necessary.

Why did you replace the original breakout board?

LinuxCNC can work with a lot of different hardware.

The bottom of the window seems to be cut off (the monitor is slightly too small perhaps), is it possible that there is some important information that we (most importantly, you) can't see?

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..

The 1N4148 diode goes across the relay coil pins, not in series with the coil.

It should block voltage when the relay is on, but allow current to flow from GND to VCC when the relay is switched off.

If your setup is parallel port, please keep in mind you almost certainly have enough output pins to control the spindle via the existing parallel port interface.

12 output pins is quite a lot.
(Enough for 6 step/dir axes!)

Your post is slightly reminiscent of this one:

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?
