I wanted to share a video showing an additional axis on a delta functioning under Release 2.03RC1. Everything seems to be working as intended.

Looks good! But can't the Bowden tube be made a lot shorter, if you tilt the extruder so that the filament outlet is horizontal or 45deg down, instead of what looks like 45deg up?

I believe you're right on a lower angle. It was a big leap for me with all the added complexity - the extruder carrage falls when the motors are not energized pulling the effector down by the bowden. So I was playing it safe until I can work around that. I will probably end up moving the extruder mount to overhang the bed a bit and get the bowden angle closer to overhead.
The firmware is really great - it basically just worked straight away with minor effort. I was shocked at it's ease of flexibility - and the added motion is highly enjoyable to watch! Thanks for developing the firmware this is great!

@gtj0 Thanks. And just to rest my mind [both the 5v -> SBC , SBC -> 5v jumpers installed and 5v En jumper (off)]. The power will go to SBC, up the ribbon cable to power the duet.

I keep getting distracted on wanting to use those ext_5v pins because they are there. I don't know why this was so difficult for me. I've wired up a few other Duets honest 0-o.

@dc42 If I configure like the second option- "If you want the SBC to provide 5V to the Duet then remove the jumper from 5V->SBC and from Internal 5v En. Place a jumper on SBC-5V". Then power is going to the SBC then up the ribbon cable (pin 2,4) to power the Duet? Where does ext_5v fit here?

@gtj0 Thanks. Do you think that's the best way to go in my situation (direct wire both)?

Seems that I could keep the internal 5v powering the duet (keeping protection intact) and external power the SBC. Also removing the +5V (pin2,4) from the ribbon cable.

Is there a board schematic somewhere? I'm only seeing the duet2.sch on github

Looking for some clarification on using an external 5V power supply with Duet3 v0.6 board. The SBC that I am planning on using can pull 3-4A + screen usb etc. I plan to direct wire 5v to the SBC and to the Duet3 so that neither is pulling power through the board but parallel.

I see the [ext_5v] 5V in and ground to connect the external 5V supply.

Then for the jumpers I have become confused. Internal 5v En jumper (off) / SBC->5V (on?) / 5V->SBC (off).

Or maybe just power the SBC separately from external 5V supply and leave the internal 5v enabled for Duet. Like 5V En jumper (on) / SBC->5V (off) / 5V->SBC (off)?
