Long story I'll try to bullet point to speed up so bear with me:
- I have a heavily modded Ender 3 Pro
- Relevant mods for this question: Control board swapped for BTT E3 RRF, Dual Z motor, BLTouch
- Ultimately I'd love to convert the Ender 3 pro to have IDEX, probably after I make it bigger with an Ender extender kit, but it's cool if it takes a long time
- Whether or not its easier to just build a large printer with IDEX (rather than continually changing my Ender 3) is a different question, but I just like modifying my printer. I like learning along the way
- Right when I got my BTT E3 RRF and my dual Z motor, I thought it'd be awesome to be able to do
G34auto alignment, much like Teaching Tech describes in this video. The BTT E3 RRF has a port for a second Z-axis motor so I thought I was good
- Come to find out that (I believe) the second port on the board is actually just driven off the same driver, I don't believe it can be controlled separately (correct me if I'm wrong).
- Somewhere on the internet I read that if you get the IDEX expansion board from BTT it can do that, so before I researched further, I bought one.
- And as you can see in this video from Aurora Tech, you can do indeed do
G34with the IDEX board.
- The problem is, it looks like in that video she actually plugs the Z motor into the slot meant for the extruder motor.
Which brings me to my question:
I want both. I want to be able to do
G34 but also eventually run a fully functioning IDEX. I've already bought both the BTT E3 RRF and the IDEX board.... am I out of luck? Do you need an Octopus board or something? Or is there a way to do both with the hardware I have now?
