My guess is Rufus is the problem, create a new ISO with Balena Etcher

Hi,
I tried Editor, Notepad++ and eq. all the same result!

Still trying to figure out what the problem is...

If I open the file with gedit from Linux, everything looks fine, but as soonas I change to LinuxCNC I have the same crap...

I have a 7I77 and a 7I76 hooked to a 5i25. And then there is a 7I66-8 and a 7I66-24 connected via serial (but I don't think those matter).

I looked for a while and didn't find / couldn't figure out with firmware I would need. Can you recommend an exact firmware?

Thanks!

To get hardware PWM you need to have firmware on the FPGA that supports PWM.
For example if using a 7I76, there is FPGA firmware that replaces 1 Step/Dir output
with hardware PWM/Dir
 

Posting your hal/ ini files would help to pin down the issue.
 

Phew, its taken a few years, but my irrecoverable account has finally been deleted and I have been able to re-register under my usual username,hoorah!

While trying to troublshoot a CNC router that has been running just fine for years and suddenly can't find its 5i25 card ... it occurred to me ... does a Mesa based install even need a base thread?  Surely just a servo thread is all thats needed?

Can I comment out the BASE_THREAD in [EMCMOT], remove the thread start in HAL and move any HAL things that were on the base thread to the servo thread?

In your INI file look for a KINEMATICS entry. Change XYZ to XYYZ to tell it you have two Y joints. Further down you end up with [AXIS_Y] but [JOINT_1] and [JOINT_2]. PNCCONF should have set this up for you.
The other important thing is that the two Y motors can't share a homing sensor input. You can share X and Y1 or Y2 and Z but not Y1 and Y2.
You may also need to reverse the rotation of one of the Y motors. How you do this depends on your hardware, of course.

1. Over the winter I modified my DYI Router Mill adding a tandem Y axis and rebuilding my Z axis support with a 2-DF gimbal  to true the spindle to the table. Today, I attempted to home the machine however, when the Y axes homed, one triggered before the other causing LCNC to complain about not being able to home one axis while the other is moving off the the home position.

What the the best way to resolve this issue such that both axes travel together, both for homing and moving off the home switch.

2. Using PNCCONF for configuring LCNC with tandem Y axes, when testing the Y axis only one of the steppers responds. Is there something that I missed in PNCCONF that will allow both Y steppers to be tested together?

3. What is the .ini PARAMETER that tells LCNC that two axes are in tandem?

Kind Regards,

So whilst trying to install you effectively had no internet connection
Same result that myself and friend of mine experienced

No problem at all I was just a little unsure who Tommy was replying too
I think the grub problem that you are seeing is down to lack of internet
Both myself and friend of mine who knows linux FAR better than I do experienced the same issue with the 2.9.8 iso when trying to install with no internet present

I installed LinuxCNC 2.9.8 on a virtual machine a few weeks back. It also failed during the grub installation phase. I'm 99% that at least in my case, something with the automatic network configuration did not work properly, and this caused the grub installation to fail. If I recall correctly, the DNS server was incorrectly set, and I had to manually edit /etc/resolv.conf to put the correct DNS server first.
