Thanks. I checked the physical wiring and the MESA I/O config. The Limit switches were not patched correctly in I/O config. Was able to successfully home everything.

I just need to adjust the z settings because the spindle isn't going low enough to the table.

Re the ISO in a hurry, you could fork the Bookworm branch of Linuxcnc's live-build which I have maintained
github.com/LinuxCNC/linuxcnc-live-build
Follow the instructions to install and run the builder after cloning

Append your build script to this file 
github.com/LinuxCNC/linuxcnc-live-build/...linuxcnc.hook.chroot
or add a seperate file starting with 520-
clone your repository into a folder under /tmp and you should be able to  build and install anything you need.

You would need to delete this file which installs Linuxcnc from the repository at Linuxcnc.org
github.com/LinuxCNC/linuxcnc-live-build/...-lists/linuxcnc.list

Add any additional dependencies to 
github.com/LinuxCNC/linuxcnc-live-build/...e-lists/desktop.list

You probably need to delete all 6 files containing Linuxcnc in the name as these are the apt settings
github.com/LinuxCNC/linuxcnc-live-build/...worm/config/archives
note preempt_rt is a dependency of linuxcnc-uspace so you will need to explicitly install it.

This will install the Ethercat repositories

You may wish to update some of these fields
github.com/LinuxCNC/linuxcnc-live-build/...bookworm/auto/config

Note that the Debian live build inherits the version of Debian you run this on. eg if you run this on Trixie, you will get a Trixie ISO

If you have any questions, just ask.

Ahh thanks, all my scripting has been done in installers as root
I tested this on my chromebook but there the user has root permissions
Something like this should then work as a script.

@Endian,

I am not ready with the .iso, but you can try this archive. Unpack it where you want.
Then : ./install.sh

I didn't test it on a fresh .iso so i can not confirm it works straight away.
After installing goto : ~/linuxcnc/cmake/configs and do : ./run_axis_9

At your own risk:
repository.qtpyvcp.com/repo/linux-distro/lcnc_archive.tar

 

I will check it in my virtual machine and let you know but the best path will be to wait for your iso file because of all the components and stuff around ...

 

 

 

Thanks for the info!
I've ordered a 7i78 now.
Is there anywhere a bitfile for the 7c81 with 7i77+7i78 available?

I wrote a bash script to create a full parallel port report following Rob's idea. It's called parportreport.

It logs:
* System info
* Kernel info
* dmesg content filtered to only the especified parallel port
* Base address, extended address, IRQ and modes
* lspci output filtered to only the especified parallel port
* ioports content filtered to only the especified parallel port
* invokes showport to show current operation mode

Usage:
sudo ./parportreport.sh X > report.txt

# Replace X with the parport number. For example, you you want a report for parport1:

sudo ./parportreport.sh 1 > report.txt

For it to work the parallel port has to be recognized in ioports. So, for now, it won't work with Sunix cards (unless you force it to be recognized)

The rar file also includes my most up to date parallel port "utilities bundle".

choose an unassigned gcode number and use a remap to fold those 3 commands into one.

This is a dual parallel port card.

Model: Novacomm PLA4
Chipset: Moschip MCS9815CV
Interface: PCIModes: PCSPP, TRISTATE, EPP
Supports X Mode: YES (in PS/2 Mode)

A detailed report is attached (following Rob's suggestion)

I updated the DIR and STEP settings after suggested and cross reference the old files. All the motors work normal. Previously the the machine showed up as XYZ and now it shows up 0,1,2,3 in LinuxCNC. The new file formatted to XYYZ config. Not a huge deal if it works like that, but would be nice if I could get 1 and 2 (Y-Axis) to appear as one again.

I'm having a problem with the Y homing currently. The Y hits the limit switch and continues trying to move forward. The numbers in CNC continue to go up -1, -2, -3...-10.

Z-Axis home normal. The X-Axis Hits the switch and doesn't back off that I can tell, but doesn't trip that it's at the limit, so maybe fine. I have alter the home settings to try to fix the issue of the Y, but I can't seem to figure it out.

Hi, 
Right now, i'm trying to control a 6-dof robot by linuxcnc, I found kinematic-switch function for moving joints from Gcode.I guess I need to make 3 Gcode commands to just do one task like:
1st-cmd: Use M code command to switch to nontrivial kin
2nd-cmd: use G code command to move joint
3rd-cmd: Use Mcode command to switch back to trivial kin
Yes, it can do my job but it complicated and not friendly. has anyone tried to merge these commands to a single one or any other way to do something similar 

50:1 worked well you can use the THCAD10 without any modification, 
Some good practices are:
-Place THCAD10 as close as possible to the Plasma power supply.
-Use a shield cable and connect the shield to GND on one side only.
-Use a ferrite bead on the control side to reduce induced noise 
 

Probably doable if there is protocol documentation.

It is digital sl2-100 not xy2-100
