LinuxCNC on Raspberry Pi 5

Just tried running a config with RPi5 using hm2_spi (hm2_rpspi is not an option ATM), completely effing useless. Constant SPI timeouts.

Went back to the RPi-400 using the hm2_spi driver no issues at all.

As I'm not in a position to test an ethernet card I really can't give an opinion regarding that option. But honestly unless you are strapped for space (wanna small foot print)I'd avoid the Rpi5 for Linuxcnc ATM.

Really disappointed with it in that regard.

There have been a few things about the screen I have seen but can't remember where. Ther is a boot parameter to set 1080p instead of the 4k default. I'm sure when there are a few more about, these will be fixed.

I've connected my Pi5 to my 7c80. I've powered my 7c80 with a 24V/5A power supply. When the Pi boots, it's complaining about getting not enough power for my usb SSD. So, the 7c80 is not delivering enough... 

There's always the option to power the Pi separately, but not with extra steps....

Still hoping that it will work.....some day.... before christmas? Who do we need to send an email, call, whatsapp, spam, ask for a bank account???

You could try connect your SSD via a powered USB hub. Not sure if you can boot that way.

That was going to be my suggestion- I do the same thing to backup my phone on an SSD, works really well.

Cant be too upset with any usability issues- Its only been out 5 minutes

I have mixed emotions about using desktop PC's. I have previously had jitter issues (just using a parallel port based breakout board) but hope that this will be resolved with a more powerful PC and ethernet mesa card - with my newer cnc machine the stakes are high if something was to go wrong. It feels good to make use of hardware which is otherwise life expired- but its hardly an elegant solution.

having a reliable, powerful, foolproof and easy to setup rpi based system would be the holy grail for linux CNC.

Once you switch to the Mesa cards jitter isn’t an issue as you don’t need a base thread.
I’ve got an old Lenovo i5 tower that I found by the side of the road that is fine for using a Mesa Ethernet card.
Unfortunately space is at a premium in my work shop.
