Tool height setter M6 subroutine question was created by thanks for the help

Tool height setter M6 subroutine question

Category: General LinuxCNC Questions

Hi, This is my first post to this forum.  I just finished a retrofit on a cnc router.  I am working on getting a tool height setter working.  It is a simple Normally closed switch.  So far I have it to where I can type in an M6 in the MDI bar and the machine will move to the specified position set in my toolchange.ngc file, the machine will run the G38.2 until I manually trip the switch, then I get an "Pvalue out of range with G10 L1", which leads me to believe at least my toolchange.ngc file is at least routed correctly. 

It is where I do a T1 M6 command or a T2 M6 command where things get a little funky...When I try to incorporate the T in that line either with or without the M6 or any tool number for that matter the "Begin executing next line" button gets greyed out.  When I hit the "Execute next line" nothing happens.   This seems behave as if linuxcnc sees the T as some kind of program it can't run.  I would like to be able to populate the tool.tbl with the appropriate G43 height off set for a given tool using the height setter.  Thank you taking your time reading this, here is the code I am trying...

O<toolchange> SUB

(MSG, Toolchange subroutine called)
(MSG, Tool number param #2 =  #2)

#<tool_num> = #2
#<safe_z> = -.5       ; safe Z height above tool setter
#<probe_z> = -3.0     ; how far down to probe
#<setter_z> = 0.0     ; Z height of the setter in machine coords

G49                    ; cancel length offset
G53 G90 G01 X1.0 Y0 F50. Z[#<safe_z>]    ; move above setter

; Begin probing
G38.2 Z[#<probe_z>] F1.0
(If probe failed, LinuxCNC will stop here)

#<measured_z> = #5063  ; captured machine Z from probe

(MSG, 5063)

; Compute tool length

(MSG, Compute tool length)

#<tool_length> = [#<measured_z> - #<setter_z>]

; Store to tool table
(--- Optional: print value to operator ---)
(MSG, Tool length = #<tool_length>

G10 L1 P#<tool_num> Z#<tool_length>

; Done
O<toolchange> ENDSUB

I start linuxcnc from terminal, then select the ui to start. I just tested again. Running a program with subroutine or without.
after finish, use the jog buttons to move xyz position. Then touch off button shuts down linuxcnc with this error.
This happens only when jog to another position and trying to touch off,after a gcode was running. On a new started ui  is no problem

Thanks. I think the install of dkms pkg exited with an error code. I added a line in the dkms.conf file to blacklist r8169.

Will try to re-install the whole thing again. What is the cmd to check what driver is installed. Is used lspci and ethtool. Is there a device manager like windows to check the installed driver?
Thanks

One thing I would check is the kernel command line options, did your previous install have any isolated cores ?
Unless the grub config files have not been modified manual editing is required for any extra options.
If the above is not the issue the Debian supplied kernel may require an in depth look at the config.

Or I maybe just barking up the wrong tree and be completely wrong, my apologies if that is the case.

Looks like the latency is worse than Debian 12 (if Debian 12 was working)

What does:

sudo chrt 99 ping -i .001 -c 60000 -q [card_ip_address]

report ?

Where [card_ip_address] is the ip address of the 7I76E

(the command will run for 1 minute and then print statistics)

Can you test with a negative value for refClockSyncCycles, like refClockSyncCycles="-10"

FlexGui -Touch off

Category: Other User Interfaces

It seems i am attracting 'touch off' troubles. Still working on my UI. After run from terminal,homing,loading a g-code file and then press touch off button (touchoff_selected_pb) , linuxcnc shuts down with an error. At least there is some info printed in the terminal. This is from the flex_examples axis:

Warning: Spoiler!



 

By run from terminal do you mean you launched flexgui from a terminal or linuxcnc?

FileNotFoundError: [Errno 2] Datei oder Verzeichnis nicht gefunden: '/home/miller/linuxcnc/configs/flex_examples/touchoff.ui'

That is an installed file not one that is in the configs directory so it makes me think your not running flex from linuxcnc.

Yes, I used that thread to do the upgrade. I reinstalled linuxcnc once again, which seems to have fixed the first issue, but now I run into the next one, please see the attachment.

r8169 is the name of the standard (and bad) in-kernel driver

It appears your r8168- dkms driver install failed somehow.

I'm struggling with mux16, I wanted to implement an decoder for a gamepad.
I although I changed this example code for easy reading and running.

If I use mux8 it is running, if I use mux16 it's not and give me the error: "./mux16.hal:11: parameter or pin 'mux_encoder.in0' not found" . Something there I missed?
