Wiring Diagram? #20

Open spikeon opened 2 months ago

Hey guys.

I'm looking at the documentation and I can't tell where exactly I'm supposed to plug what in to what. If you could put together a couple of sentences or a diagram of how to attach the electronics of this to the rest of the ECRFv2 system (or point me at the documentation I didn't see), I would greatly appreciate it.

Thanks!

Noted! Working on it

What board are you using? In case you are using the BTT MBB, I would just follow the ERCFV2 manual and use at the end a free pin of STPx . According to our testers the board has plenty enough power to supply the cutter servo.

Yes, I'm using the BTT MBB. Does that mean I don't need this buck converter thingy I bought?

Some people are using the BTT MBB 5V supply without any problem but I would recommend using still a buck converter for now at least, I will try to contact BTT and hear their thoughts on this topic. So connect it like this

Servo Data Pin -> Some free STPx pin Servo + -> Buck converter + Servo - -> Buck converter - DON'T FORGET TO ADJUST THE VOLTAGE OF THE CONVERTER BEFORE CONNECTING THE SERVO! The needed voltage is on the spec sheet of the servo, usually around 5-7.5V

Yeah, I figured that I'd screw that up so I bought a buck converter that outputs 5v.

I don't trust myself with "If you set this dial incorrectly you destroy expensive things"

Speaking of the buck converter, do you have a recommended place to put it? I was thinking about modifying the housing of the ERCFv2 BTT MBB to be a bit thicker so I could mount the converter to the inside of it. But maybe printing it it's own housing and then gluing it to the outside would be better.
