m8p+cb1 temp error after flash to can RatOs v2.0.2
#fix-my-printer
hi
I have RatOs 2.0.2 on m8p V1.1 andCB1.
After setting m8p to CANBUS for use with BTT MMB (ercf v2) I have this at idle.
I'm now trying RatOs v2.1.1rc2 on new SD card, should I set it with or without tool head board?
Still have SD card with RatOs 2.0.2

Printer worked fine before I flash to CANBUS.
Only change [MCU] from ''serial'' to ''canbus_uuid''
And add
[mcu EBBCan]
canbus_uuid: ########
canbus_interface: can0
To printer.cfg
To communication test before installing Happy Hare
I'm not able to help you with CANBUS. Follow the instructions from the the mfg and ercf/happy hare i guess.
Only USB connection in HH Guide for MMB😢😭.
Thank you
All you need to do is change the firmware to communicate via USB and skip all the ceremonial CAN steps, nothing else changes.
That because I will install in future the ebb sb2209 can.
M8p as only 2 USB port and have 2 cam .
1 for time lapse and survey and the seconde to survey the ercf.
I'm truck driver so I can go through Google desktop to manage my PC and printer
That because I will install in future the ebb sb2209 can.That runs USB too.
M8p as only 2 USB port and have 2 cam .USB Hub.. I recommend the Waveshare USB 3.2 gen 1 4-port hub.
Yep good idea
I take a look tomorrow over this USB hub.
👍👍👍
Solution
@miklschmidt
It's works
I have switched the UUID from M8p and MMB
That was my error
Unfortunately it'll fail when RatOS.cfg is regenerated and the
serial option is back.After flash to CANBUS I have this infos in putty
Waveshare 4-Ch USB 3.2 Gen1 HUB, Compatible with Windows, macOS, Li...
4-Ch USB 3.2 Gen1 HUB, Metal Case With Wall-Mount Support, Driver-Free, Plug-And-Play, Multiple Systems Support
that's the one
I have only to put ''#'' and it's good.
And this warning
Maybe reflash m8p to can after update
That not a big prob.
10 min and I'm good to go
Now it's time to install HH and setting it 👍
You're not supposed to modify RatOS.cfg, it will be overwritten automatically
I noticed it, it updates itself at each reboot, that's why I went back to version 2.0.2 after noticing my mistake with the can UUIDs that I had reversed
So I run now RatOs with MMB in canbus and HH without problem
@miklschmidt That is the waring I got after flashing manually the board to CANBUS (m8p v1.1) that why I asked if I should set RatOs v2.1rc2 with an ebb (btt MMB) is not listed
RatOS doesn't support CANBUS (it can't detect the board anymore), you'll have to manually babysit your board like in standard klipper when using CANBUS.
Ok then I have 2 choices:
- I can go with CANBUS to use the 2 CANBUS port of the m8p, but manual update.
- Or buy an USB Hub to have full auto update of hardware
Well you know which one i vote for 😄
Yep
Full auto on usb
