After getting the Idea of making a custom module, i orderd a couple parts and got to work. As im not great in coding, ive started with a separat CANbus only module. I want a more open Connectorsystem, ive chosen DB9 connectors. There are no Cable from SN to DB9 so ive orderd 4 and 8 Pin cables. …

Its been ages since an update, stuff got in the way. Thought recently to work on this Project some more. Sofar, Buzzer and RGB LEDs “work”, OLED isnt used to the extent i would like. Casualty list: 2 Teensy 4.0 8 CAN Transceivers 2 DCDC Converters Eyecandy: [Snapmaker CANbus Test] …

[image] Streupfeffer: CANbus is sorta saturated What’s saturating the bus?

I think the Teensy has issues handling the two CANbus’. Im currently hookedup to the right Connector for extensions. The teeny is forwarding messages from one to the other with minimal filtering (currently just ID21 for limitswitches). After a while, i can disconnectt the Snapmaker, the Backlog of M…

Got the Buzzer working, it can now even be configured for volume and off-time (between beeps) via CAN. RGB LEDs have now the issues that they dont update imidiatly (No safety stuff so not critical). I think the many timechecks are messing with the time keeping for Data sending.

Just stumbled across this project - good work, thanks so much for sharing!

Hi guys, I am new to this forum. I just found this post and am impressed with the great work done by Streupfeffer. :+1: I’m also trying to do something similar - but so far it’s only an Arduino based prototype. @Streupfeffer : I am very curious about the final of your project? What else are you…

The PCB is just laiyng around currently, i had to ordner new CAN Tranceivers after ive killed all i had around. I have started to look into making a small IO expander board for CANbus, parts are laying around on my workbench currently. Work is slowly progressing but it isnt a priority. The IO expa…

Hehe, ATTiny now is reacting to Canbus. No Transceivers or other chips died, sofar. Left is again the SN<->Teensy interface board, Top left is the usual can Analyser, top right are Atmel ICE and Digital Discovery for CAN, SPI and UART decoding/ monitoring as the Tiny doesnt have a serial to USB por…

Thanks. PCBs are on the way - should be delivered in about 10 days. Well, we’ll see … maybe there are some bugs in the pcb design :rofl: and i will have to make some corrections. But back to your module - as you probably know, the Snapmaker controller has 2 independent CAN buses. The ID messages …

I realy like @Ronin Board aswell. Looks sleek and optimised for its usecase.
