My build is pretty old, and my thread is pretty long with me kind of figuring things out. This thread will be specifically about the work I’m doing now, so I can stop (hopefully) worrying about poor wiring and just cut some more stuff. Things I would like to add to this build:
- Get my mini rambo on it. I’ve had this for a while, waiting. It’s time to put in on my LR. No more potentiometers!
- Get an on/off switch on the mini rambo, but not the v1pi.
- Get Marlin on there. I’m ready to say goodbye to grbl, at least for a while and the mini rambo should be great.
- Get my Router Relay installed on the side. This will let me power on/off the guy. I suppose I could use the PID. I might actually do that. Hmmm. Either way, we are bringing back M3/M5!
- Box up the pi, and controller with a fan. I don’t think I need a filter.
- Install captive wire connections. I had ruined a couple jobs with the duponts failing. Not sure why, but I like these JST-XT or whatever. The only problem is, the male pins are all through hole soldering, so I can’t easily do wiring or connect cable to cable.
- Wire the steppers at the controller. This is related to the JST connectors, but I had an idea for simplifying the serial wiring and I want to try it out.
Unfortunately, the LR is down until I at least finish the wiring, so it’s table saw, drill press, and 3D printing for the time being.
Here’s what I’m thinking:
The small board in the middle is a 5V power supply for the pi.
There is a voltage and current meter in the left panel.
I am thinking that I want 12V to go to the current meter first, then the 5V PSU, and only have the switch for the mini rambo. That will give me an “oh shit” switch, but I can leave the pi on when I’m laying testing things out on v1pi.
Here’s a pic of the panel I printed today:
