Your documentation is GLORIOUS!

I have all the parts and all the tools.... time to build this!

Thank you for the enormous effort. I design / engineer commercial products and have developed a keen understanding of the challenges these things can be. So many details.

I’m hoping this is easier than it looks… parts are coming in slowly

Thanks for the detailed video ... I have replayed the video over and over, and I don't know where the camera wires plug in? There are four wires after cutting off the USB end! 1. White 2. Red 3. Green 4. Black. I assume as always red is power, and black is ground, but the green and white? No mention as to their location. In your video you have marked it with "C" for camera, but skipped the part to connect. Your help is greatly appreciated and thank you very much for your time and commitment to this project. I'm so close 😀

First thank you for making this I'm trying to build one, i have a question i noticed in the CS71_Arduino.ino is a newer since you made the video and that PWM is set to false, is the external pwm not need any more? just the resistor inline?

Hi there
Jesper from Denmark here.
I am Building your Nice sorter, and getting pretty close. But I dont get 5 volt from the pin on the board.
Should the code be loaded first?

What's the discord channel? And I missed the TMC2209's in the parts list. I had TB660s from an earlier build, but I don't think there's room to stuff those babies in. Any particular flavor of the tmc2209s? Looks like you're keeping them down at or slightly below 1a ?

About the feed homing sensor and sorter homing sensor. The instructions says to connect ground as well as 5V+. But the sensor is just s switch, nothing that uses power. I take it that the instructions are wrong, but can't be sure wether to use the NC or the NO for the connection to the Arduino.

I love the project, had a question, i was looking at the audrino uno R4 Minima, was curious if you have experimented with faster pricessor and larger memory with this build?

Hi
Why jumper on M2? Doesn’t this turn off SpreadCycle and turn on StealthChop2? Isn’t SpreadCycle better for optimal performance?

Thanks!
