First thing you need to do is get the pci_id.
That will show you a list of PCI IDs and module parameters.

Then you can use modprobe to load partport_pc using the parameter that's required to set the address of the card.

Now whether the kernel module loads automatically for that card will depend on whether the PCI ID is a match with the driver.
If you can give me your kernel version and PCI ID of the card I can check the kernel sources and see if I can find a match. If not for the kernel you're running but one that might.
In all honesty for the headaches that a parallel port can cause a mesa 7i92 plugged into your existing breakout boards is a better solution. Latency isn't a problem, migration to a another PC is easier.
But I get that parallel port cards can be cheaper.

It will be noted on the splash page

Are you on stable or develop version?

I think your method of fixing this by applying a tiny offset worked because it meant that the the loop was no longer complete so its signed area was a lot larger. Although likewise, adding this offset could technically break a curve which would have worked without it?

The offset is not breaking the curve, and the curve is valid without this offset.
The 1e-12 offset was made to get the curve out off a singularity.
The 4-clothoid constrain formula has this result in rare cases where local clothoid plane alignes with global world plane.

We have input xy angle, input z angle for the clothoid fit.

The abstract could also use vector rotation as input, wich can be used to set the
torsion in and out rotations. Technically you can create clothoid helixes using this torsion turn value. But the abstract does not
use this oppertunity.

@Arciera,
Thanks for your contribution!

I think they work consistently on HP PCs.

Well, back here with some questions. 


Just like what happened to me with the mill, in the lathe interface I've enabled keyboard jog and disabled the safety key, but it has no effect and I have to keep holding the Ctrl/Alt key. The + key for fast forward doesn't work. Is there any way to change it? 


The keys for moving the axes with the keyboard are the same as those for the mill, and it's very inconvenient because they're separated. Can I change it so it moves the same as the axis?

The big screen turned out really nice so next step is to make the keyboard shelf ready and alot of push bottoms:)

This isn't a great solution, but I don't have the access to fix the Dreamhost certificate.

But, you can copy the download link, then paste it into the address bar of a new window, delete the "s" in "https://..." and then it should download the file.

I think we would need a better macro photo to tel if that was a fatigue failure or not, but it leads me to be rather suspicious of the motor-to-shaft alignment and mounting. Is there any type of flex-coupling there?

Pretty.

Looking at the code around taskintf.cc:976 that error indicates that EMCMOT_JOINT_ERROR_BIT is being set. Have you tried tracking down what might be causing that?

Short answer:

My Powermax is paired with a THCAD-10.  I changed it to 20:1.  It’s served me well with no issues over the years.

Long answer:

I wonder if there is a way to force these Sunix cards to load parport_pc driver and module from the I/O ports address?

So it will showup in dmesg as a proper enumerated parallel port.

Why?
I had two of those, both showed everything on 2 different PC's, but 1 did not show driver and kernel module on a 3'rd PC. Same card did show on 1 PC and did not show on another PC.
On the PC that did not show modules another PCI card did not show modules loaded, after showing them and working for years.
All this points to something in BIOS causing that, but i am out of luck as i can not find any more of those Sunix cards.
Here is one example of it showing modules loaded

As to why adding 16 to the mode doesn't work...

I guess that the problem comes if the orient.0.mode pin is connected to spindle.N.orient-mode, I didn't realise that the P number had a limit check on it.

If it is controlled by a "setp" in the HAL then it should be fine (with the spindle.N.orient-mode pin left unconnected)

That means that you can't change the mode with the P command in M19. I don't know if that is really a problem, though?

It depends on your machine amperage. No scaling resistors are rwquired. Most people use 20:1 which gives a 200 volt full scale, 125 amps might be better at 30:1. (300 volts)
The thing is that the THCAD is rated for overvoltage of 500 volts. The voltage will only go over 200 volts on piercing when we do not care about the voltage then. During cutting voltage is between 100-170 volts. Keeping the max voltage range low means the readings are more accurate as more of the ADC's range is used. 50:1 is popular with a lot of non-linuxcnc THC's  (probably with a 0-5 volt ADC). That would be better for a THCAD5.
