Here's a guy that did a QT8 retrofit.  Could try reaching out to him to see what was involved. I'd try to find out what issues the lathe has and plan from there.  From a very quick look it looks like the servos have resolvers, so you'll have to plan for that with your choice of controlled cards or plan on replacing the servos and drives with something more modern with encoders.  

Hallo zusammen!

Ich heiße Bernhard, bin Mitte 40 und komme aus dem Osten Österreichs.
Beruflich bin ich in der IT unterwegs, und habe auch etwas Erfahrung mit Linux.

Daher war das ausstatten meiner vor 5 Jahren angeschafften kleinen CNC Fräse (Mutronic Diadrive) mit LinuxCNC logisch, und das funktionierte auch im großen und ganzen sehr gut.

Die letzten 5 Jahre lief ein PC mit einem ASUS Mainboard aus 2005, an dessen Parallel-Port direkt die Fräse hing.

Wie zu erwarten, macht das natürlich irgendwann Probleme. Im Moment wird die Festplatte (SSD) nicht mehr erkannt.
Ich krieg das grundsätzlich zwar sicher wieder hin, aber möchte das eigentlich gleich nutzen um auf aktuelle Hardware umzusteigen.
PCs mit Parallel-Port zu finden die dann auch akzeptabel funktionieren dürfte eher die Nadel im Heuhaufen sein.
Alles was mir so in den letzten Jahren vor die Füße gefallen ist, hat im Latency Test grausam abgeschnitten.

Daher meine Frage an die Wissenden:
Was nehme ich 2025 für Hardware, um eine Fräse anzusteuern die einen Parallel-Port Eingang hat.

Ich lese was von Raspberry Pi, Mesa Karten, ..., blicke aber ehrlich gesagt nicht durch wie das alles zusammenspielt.
Eine Raspberry Lösung fände ich sehr sexy, aber was nehme ich dann als Umsetzer zur Fräse?

Habt ihr eventuell Links zu funktionierenden und dokumentierten Setups, oder Tipps in welche Richtung ich mich weiter schlau machen sollte?

hilfesuchende Grüße,
Bernhard


 

Apparently, it is waiting for me to complete an M6 tool change, which is not set up in my hal file. I'll keep digging.

This is what i was doing last few days, a very small 4 axis cnc machine for cutting some kind of plastic material for clear teeth aligners, machine is fully finished (except a box for electronics and cutting the protruding HGR25 rail to size).
-The machine kinematics are simple XYZC.
-The mill bit is angled at 35 degrees from table, can be changed to 90 or any other angle
-the C axis can spin freely both directions and has a home switch, with limits at+-99999 in ini only
-table/C axis is designed in FreeCAD and 3D printed, with 120 tooth HTD3 pulley included


Below is what i have to work with:
-the file generated from their software is a simple text file (.pts extension) with values for 3 axis, BUT has no axis assignments at all, only numbers, so with a bit of help from Gemini a filter was made to open the .pts file and assign axis letters together with Feed rate and M2, all that works fine
-also made a filter that adds the fourth axis that also seems to work, but not as required by this task, C does move small amounts to account for the tool cutting angle, but this requires rotating the C axis 360 degrees for a full job
-that job is always a single cut line, always same location of the material, always indexed on C, material shape does change but never significantly
-that is the only job this machine will do.

-
The machines used for this are 4 or 5 axis, always, and they use that same file type with 3 axis values, so the kinematics or CAM must do the required changes/modifications to path, and this is where i am stuck, so any ideas are welcomed.

Ok, today I had the opportunity to check my signals. I started with analyzing the "reset" button, which is supposed to turn on/off the machine. When on version 2.9.4 the button toggles "halui.machine.on", which then activates "halui.machine.is-on". This is what I expected to see.
When on 2.9.6 I see that "halui.machine.on" is toggled, but i never get the "halui.machine.is-on" to become true. It isn't even true when I switch on the machine via the F2 key. The machine functions, but this pin never says it is on.
How could this be explained?

Починила, помогло, спасибо

probably using the
motion.feed-hold
or
motion.feed-inhibit
pins, but these may leave the spindle running and that might not be desirable.

./sodick.hal:22: classicladder exited without becoming ready

Maybe I wrote something incorrectly, but when I enter the parameters, the classic ladder error simply doesn't start on its own.

I have not published a video for a month. I was puzzled to see that there was an upwards trend in my views which had doubled during the month without any new content.

I think this was because I added AI generated thumbnails and revised titles to be more in line with what Youtube wants. TIme will tell.

Yesterday, I published a new video about installing on Trixie and its the best performer I've done. I think this was because I followed a script, added some chapter heading banners and used a cheap Teleprompter (which I also bought a foot switch for). I also used my DSLR with a 50mm F1.4 lens. The ficus hunted a bit but the deot of fields is nicer when I am in focus... You be the judge


I bought a video switcher and I want to do an installation walkthrough but last night I realized that the HP PC I wanted to use does not have an HDMI port so Ihave ordered a VGA to HDMI adapter. Hopefully I will be able to capture the screens from the BIOS and the Debian Installer. Wish me Luck!

I think I have gotten the firmware situation figured out, but now I am trying to add some things to the machines hal file for the retrofit based off a guide for a maho 400e. I added the following and now the cnc panel gives me an error. it seems to be saying it cant find pins on the 7i77

added to the machines.hal file=

You might need to increase the number of pins (default is 15 input- and 15 output-pins):

hello,

I've spent hours playing with the PID values ​​and still have the same problem...
In the meantime, I've made progress on other points on the machine to take my mind off things.

If I move the spindle to 45 degrees, then 145, 245, and 345, no problem; it positions itself correctly at the value. However, if I move it from 45 to 245, the spindle goes to maximum speed without stopping...

But since yesterday, I've had an interesting lead. When this doesn't work, I realized that the spindle command becomes negative (LCNC, probably choosing the shortest path, by wanting to rotate the spindle in the opposite direction).
And that's the problem: the spindle doesn't change direction, so the PID drifts...

To confirm my idea, I made the same movements, but imposed the rotation direction with an M19 Rx P1.
And then, if I move the spindle from 45 to 145 degrees or from 45 to 345, there's no longer a problem; it positions itself every time.

I've probably found the cause, but how to resolve it, I don't know.

Do I have an error in my HAL or am I missing a line?
Do you have any leads?

The LEDs are working properly.
The label translation is perfectly sufficient.

Thanks for the good work.

Switched to the generic driver, ok.
You probably need to add the configPDOS="true" to the linelike
