To my believe, bookworm is as new as can be, so not "behind"

Not quite, what you get with bookworm is what has been sent to the debian organization at the time.  There have been bug fixes in 2.9.2 since that are not in the current bookworm packages.

 So, would you like me to jump to 2.10x? Guess that's not released, yet?

I was suggesting to change the linuxcnc package sources to linuxcnc.org instead of the official debian bookworm repositories. The link I posted should show you how to do that.

Danke, funktioniert soweit alles

Thx a ton, sure looks nice!

PS: opening up manualtoolchange.ui using glade_gtk (version 3.40) says, manualtoolchange.ui is vor GTK 2.16 but this (my) version is only for GTK+ 3. So I should make sure I can start it with glade 3.8 without outdated widgets. This is my translation from German to English. Actual wording will be different, for sure

PPS: as you may notice, I am on 2.9.2 already. So, would you like me to jump to 2.10x? Guess that's not released, yet?

After having a bit of a search the readme also states this.

Steps for setting parallel port :

---

method 1(default):
1. rmmod lp
2. rmmod parport_pc
2. insmod parport_pc.ko io=bar0 io_hi=bar1 irq=number.
ex: insmod parport_pc.ko io=0xd010 io_hi=0xd000 irq=11
3. modprobe lp
Note: Here, the io, io_hi and irq should be noted from lspci -vv.
 

modprobe lp can be leftout.

The correct command should be sudo halcompile --install wj200_vfd.comp

You really need to give the output of the 3 commands at the beginning of this thread.
Please do it before loading the kernel module.
The lspci one is quite important as that will show the Vendor & Product ID. Once I have this I can check if the vanilla kernel module already supports your card. The result will give an indication of what is the correct address.
Unlike Windows with Linux it is very rare to find a consumer hardware device that does not already have a supporting kernel module.

Actually since you have already installed the kernel module it may be best to boot from a live session from your installation media so we are starting a the beginning.

Not sure how far behind the bookworm package is but '/sim/axis/remap/manual-toolchange-with-tool-length-switch' runs for me on a 2.9 build from February:

 

Maybe updating from the linuxcnc.org sources would help:
linuxcnc.org/docs/2.9/html/getting-start...dating-linuxcnc.html

One possibility that comes to mind is to
1. smooth the tool position trajectory (ie XYZ) as Grotius has been doing
2. create a second 3d trajectory that is offset from the tool position trajectory by a fixed distance along the tool orientation vector
3. smooth this second trajectory using the same method as in step 1
4. calculate the smoothed tool orientation vectors
5. calculate the smoothed orientation angles (ABC) from the smoothed tool orientation vectors.


I found a paper that may describe the method above but I do not have access to the full text:
www.researchgate.net/figure/3D-clothoid-...ector_fig3_361356637

The pins starting with 'FP4-gearbox.' would likely be coming from a custom hal component. I cannot say for certain as I don't know which hal file you got this from.

I'm a bit (or more than a bit) flumoxed at this point. I'm running a Dell Inspiron 3668 with a StarTech PCIe Parallel port card (AX99100x chip). I seem to be getting decent latency, but it doesn't appear to be working within the software. If I don't load the driver it complains that there doesn't seem to be a parallel port there, if I do load the driver:

sudo insmod parport_pc.ko io=0xd010 io_hi=0xd000 irq=14

then the error that no port there goes away (sort of). I have to sudo rmmod parport_pc.ko and then re-insmod it after each reboot. However, it still doesn't actually appear to be twiddling the bits on the parallel port, more disturbingly dmesg comes up with the following:

"parport_pc: loading out-of-tree module taints kernel."
"parport_pc: module verification failed: signature and/or required key missing - tainting kernel"
"parport 0xd010 (WARNING): CTR wrote 0x0c, read 0xff"
"parport 0xd010 (WARNING): DATA: wrote 0xaa, read 0xff"
"parport 0xd010: You gave this address, but there is probably no parallel port here!

So it really looks like I'm giving it the wrong address when loading the module, but they tell you to do an lspci -vv and it reports IRQ14 and gives two addresses 0xd000 and 0xd010. I've tried both combinations to no avail

Sorry didn't notice

 
 

The lathe screen is only available in the development version (2.10 master) of linuxcnc.

BIte the bullet and upgrade to 2.9.2
2.7 is just toooo old.. SO many new features

i am using this device as you recommended in this post
