LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

Category: Computers and Hardware

Put my PCB together! It works! Very happy to have moved on from breadboard to something more reliable!

"KeyError" suddenly appears after moving a limitswitch

Category: QtPyVCP

"Key Error" means that the system is looking in the object returned by getWcsOffsets() call for an item that doesn't exist.

It looks like, for whatever reason, the getActiveWcsIndex() call is returning -1. There isn't a -1-th WCS, so it returns an error message.

This looks like qtPyVcp isn't handling the case when the apparent WCs is zero properly.

github.com/kcjengr/qtpyvcp/blob/main/src...c_datasource.py#L194

I think you should raise this as a bug:

For reference, my PCI motherboard (I have forgotten what it is, but that doesn't matter) in which I was using a Mesa 5i23 PCI card died.
I tried a PCIe to PCI adaptor in a DN2800MT motherboard running Debian Wheezy and it didn't work.

But when I tried an Asrock N100DC motherboard and Debian Bookworm it worked fine.

One of these (though the link will be dead in another 5 years)

How to install kernel patch? (Moschip 9900)

Category: Installing LinuxCNC

I would test with the motor power off (and maybe parallel port disconnected)
to verify if this is a noise issue (noise ground path through parallel interface)
or a software issue.

scale: already exists
...
./whb04b.hal:20: insmod for scale failed, returned -1

You are probably trying to "loadrt scale" in two different places.
You need to combine them into one "loadrt" that loads as many as needed.

(Or you can use HAL_TWOPASS, but that may be more work)

If you start LinuxCNC from the command line (just type "linuxnc" do you see any mention of not being able to find the tool table (or possibly vars file) in the output?

Set program zero using XY positioning laser

Can If you post your hal/ini files?

The error is likely caused by a missing or mismatched

loadrt abs xxxxxx

You don't seem to have "addf"ed the lowpass and abs to the servo thread.
(See the other components in the HAL file for examples)

Set program zero using XY positioning laser

Upon restart the following error was spit out:

ERROR: function 'abs.spindle' not found

Checking the HAL file it appears to be caused by this line:

addf abs.spindle servo-thread

Vorschau Berechnung der Grenzwerte passt nicht wenn M6 enthalten

Category: Deutsch

Du kannst Teile deines M6 Remaps durch Abfragen des '_task' Parameters vom Preview und somit von der Limitüberprüfung ausnehmen:
o100 if [#<_task> EQ 1]
 ; alles was hier dazwischen ist wird erst beim eigentlichen Abarbeiten des Programms berücksichtigt
o100 endif
