It's a one to one connection. Pin 1 to Pin 1 etc. The wire with the red tracer is pin 1.

Ok 120GB is going to relate to storage not ram.

What is the spec of your RPi5 ?
What image did you try ?
How old is your Rpi5, when did you buy it ?
Could you possibly take a picture of the screen ?

I cant get Linuxcnc to boot  on pi 5. 4 skulls and page full of text. what am i ding wrong? 120GB pi 5 

That worked thank you!

I am now getting a "joint 2 on limit switch" error when i try to jog the machine on start up. The only other thing that changes is i went from gmocappy to axis (since i no longer have a touch screen).

I went to hal show and tested all three (still waiting on the fourth) limit switches and both estops do what they should.

Should i undo the "-not" ? If that was the case shouldn't it be all the joints?

A cleaner, linear response signal could be the ticket, as I have fiddled with the PID parameters quite a bit as well as my Z axis velocities and accelerations and it is still not really where I'd like it to be.

Have you considered linearizing the output (with lincurve) before feeding the linearized distance to the
PID loop?
 

 

PCW: That is not something that I had thought to try. I'll have to give that some thought and see how it performs. Thanks for the tip


prokopcio, I'd recommend starting a new thread in this subforum so we can discuss your design. Looks promising!
