Hi All
Please can someone suggest next steps to try to get this to work.
I am a novice at this, so it must be something obvious, it’s just not obvious to me

Please see hal, ini, io attached.
I have a gantry X Y Y Z (two y motors)
I am using a Mesa 7i92TM connected from P1 to a Mesa 7i76U.
I have tried latest linuxcnc images on both Raspberry pi4 and on Intel NUC, and get the same outcome.
I used current version of mesact

The Linuxcnc dro counts on the screen, but the actual motors don’t move.
It looks like It counts in all axis until the software limits are reached, then errors.
When switched off, you can move gantry by hand in any direction.
When switched on, the gantry is rigid.
Stepper drivers are all DM556T.
Green led shows on all four of the stepper drivers (no red led on any of them)
I have wired from 7i76u to stepper drivers in differential mode, and in single ended mode with common ground, it made no difference, no axis moved.
The watchdog led in middle of Mesa 7i76U is green, and flashes approximately every second.
I have four inputs. Limit switches on the x and z axis, and proximity sensors on both ends of y axis.
In halshow, all four inputs are yellow, and go red if you trigger any of them.
Please can you suggest where to look next, or what config changes to try.
Many thanks

Hello
I put my pi 5 into operation yesterday.
Unfortunately I get the locale error with Pconf

I tried to use the same settings as you.
My keyboard is german

Do you have an idea?
 

I *think* you have to set the localle etc from menu-config - mine was not set for me.

If you're going to use a CM5 & carrier board you'd be crazy not to use an NVMe drive. It's fast, like really fast. I use one with mine Rpi5.

I have a LinuxCNC image running on a CM4/eMMC, so it should also work on the Pi5.

Hi, I got my latest image working. In /boot/broadcom under config.txt, you need to comment out the line that enables SPI: dtparam=spi=on -> #dtparam=spi=on.
Then you can use GPIO7 and GPIO8.

You do not need to load hal_pi_gpio, it doesn't work on PI5.

The good news is that you don't need it, either.
