Error finishing read! Iter and joint following error in Stepper machine

Category: General LinuxCNC Questions

Hello guys
i am getting some errors related to stopping the movement of the axis suddenly with a Error Finishing read and joint following error although I have a 2000000 servo period.

is there anyway can I improve my ini file to get over this?
would it be ok to increase servo period further?

thank you

Touchscreen mit Debian 12 und LCNC 2.9 nutzen?

Category: Deutsch

Also ich hab zwei verschiedene Touch am laufen, ebenfalls an Lenovo ThinkCentre.
Einen 15" und einen 21"
Installieren musste ich bei beiden nichts.
Das USB Kabel hast du schon eingesteckt?
Versuch mal einen anderen USB-Port am Rechner, da sind nur zwei direkte Ports, die anderen laufen über einen Hub.
Kann sein das macht Probleme

Working on sheet metal parts as well.
Half guard chip pan. (upper enclosure can bolt on top). i made the rear way cover a tunnel. this lets me keep the depth of the enclosure much smaller. 680mm machine full depth now (not counting door handles etc). Width on the left is the main issue now.

I am still getting the same error even after disabling these. Is there anything that can be done further maybe give the computer more margin for error if thats possible?

Category: Basic Configuration

Hello, I'm trying to configure ATC, currently I have a manual tool change with sensor approach.
[RS274NGC]
PARAMETER_FILE = linuxcnc.var
FEATURES=30
SUBROUTINE_PATH =  macros
REMAP=M6    modalgroup=6 ngc=tool-change

How can I configure LinuxCNC so that before measuring the tool, Linux moves over the selected tool.
Tools in a linear warehouse. I don't know what to add to the RS274NGC section. 

Thank you for every helping hand :)

Sadly, it doesn't look like it's the cable. Multimeter says all pins are connected and not twisted (I didn't exhaustively ook for internal shorts, maybe I should check that, but seems unlikely).

I'll try the default configuration file and see if Z axis functionality is restored and then compare the files.
