Thanks again. Initially I plan to do this using a Raspberry Pi using software stepping through GPIO, so I am a bit concerned about the Pi being able to keep up with encoder pulses. If it doesn't work on just the Pi, I will get a 7C81 Mesa board for it, but want to try using just the Pi first.

I don't ever see needing to use the spindle as a dividing head. I have a 4th axis on my mill if I need that, so I think two encoders, one for index and one for pulses would work okay for what I need. We will see.

Looking at your picture, that is almost exactly what I was picturing for the slot sensor mounting. I may try a 3d printed slot wheel. We'll see if it flys apart, but I generally don't run too high speeds and think it will be fine. I'll print it at 100% infill and make an aluminum hub to sanwich behind the pulley.

What brought this about is that the threading nut setup on the lathe broke last time I needed to thread a part and I figured it was time to convert to CNC. I plan to include 2 MPG handwheels mounted on the carriage so that I can mimick a manual machine for times when I just want to do simple turning. I have that worked out on the Pi already. I use a handheld wireless MPG on my mill but am thinking about adding 3 handweels and eliminating the wireless MPG. I've had a few loss of connection issues with it in the past.

This is a long term project so things won't happen too fast. I have access to a friends 13" Clausing lathe if I need one and he is only about 3minutes away. I have another big project I'm working on and this one is a fill in for times when I need a break from that one. Thinking about the basic X-Z conversion, the Z axis looks like a piece of cake, and if that 12mm ballscrew I got fits, the X axis cross slide won't be too bad either.

Thanks again.

Simple Mesa Setup



Thanks to PWC

You definitely do not want DHCP and you do
need to set a static address.

You might try this:
DO NOT set a gateway or nameservers

I checked that thread and I haven't seen anything to address the Sync manager Watchdog.

Check this thread forum.linuxcnc.org/ethercat/54965-stepperonline-a6-servo maybe there is a solution

to set up, first connect the Ethernet to your router and let it get an IP address via DHCP
To set up wifi, follow the instructions on the downloads page.
Now you have it working if you need to set up for a Mesa card, follow the instructions

I don't know where you saw the info about the setup wizard, but this is absolutely wrong.
As the image is essentially Debian Bookworm you can use the below link to get an idea. Also there is a large sticky thread related to the RPi images, in the Installing Linuxcnc heading.
What other image are you referring to ?

wiki.debian.org/NetworkConfiguration

I installed Linuxcnc on an 8GB Pi5 using this file since I want to use a MESA board, it looked like the right choice.

www.linuxcnc.org/iso/rpi-5-debian-bookwo...25-01-27-0140.img.xz

Everything booted up well(but there was no initial setup wizard like I have seen some people mention), and the install looks good, but I don't see wifi anywhere or network options of any kind. I tried a USB wifi dongle, and that didn't change anything and unfortunately, ethernet is not an option for me. Does anyone have any tips for getting wifi working? Should I have used the other .iso? Thanks!
