Hi all,

So I thought as I'm now a Duet3D convert I should post my new printer build. First this to say it's still very much a work in progress, it's going to be an iDEX printer but currently only has one tool carriage installed, while I get to grips with the firmware side of things. This is my first Duet3D board so it's be a learning experience but once I got my head around it, it's going well.

So spec are currently,

Duet 3 0.6 with 3.1.1 firmware with a raspberry pi 3B attached.
300mm on X, 270mm on Y and 300mm on Z.
It has a Prusa MK3 extruder on a magnetic carriage system, allowing for quick hotend swaps.
E3D V6 hotends 24v.
700W Keenovo 240V AC bed attached to a 5mm Aluminium Tooling Plate.
Bed leveling is via a PINDA v1 from my old MK2.

So when I say it's a D-Bot/CrusaXY mash up that basically means I used my 300mm D-Bot (Link) for parts to make the printer designed by Hunter Bernstein on thingiverse (Link). The parts I printed are version 1 and they have been updated but I'm going to use this for now. The idea behind Hunter's design is to use a Creality3D CR-10 S5 and convert it to an iDEX printer, I didn't have a CR-10 so when the D-Bot conversion route.

So on to some pictures, I will be updating this thread as I add the extra tool etc but for now this is what it looks like.

So as you can see I'm using a quick disconnect extruder board, these are connected with a 26pin ribbon cable and so far works great, I remixed some things of thingiverse to make a bracket that holds the cable and I used some flat 9.5x0.3mm spring steel to support the cable (Like the E3D tool changer)

Well that's about it for now, I'll post updates soon.

Thanks,

James.

Hi,

First you have two M584 commands in you're config.g.

M584 X0 Y1 Z2 E3

M584 X0 Y1 Z2:4 E

You also have (,) in you're M92 command.

M92 X80.00 Y80.00 Z634,5 E387,37.00

These need to be (.).

@T3P3Tony

Thank you, it wasn't until after I made the thread I realised there was a better category but couldn't change it myself?

I had mine setup as Input PIN io7.in & PWM Control Channel (BLTouch only) as io7.out, NO Modulation Pin.

And follow the wiring here, https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_BLTouch

Hi all,

So I'm finally getting around to adding the second extruder to my iDEX printer and I was wondering if someone knowledgeable would be kind enough to take a look at my config I've made? I'm waiting on a few connectors and tool so the printer isn't currently moving so I've take a guess on some of the offsets but some advice with that would also be appreciated but it's more the setup and naming of things I'm unsure of.

Edit to remove config files, as I'm making changes to my config. Will request help again soon 😜

Thanks in advance, James.

@Noah

The first thing that stands out is you have defined multiple E factors in your config but you only have one Extruder, I think you meant to set multiple Z factors.

Ie

M350 X16 Y16 Z16 E16:16:16 I1 ; configure microstepping with interpolation

@phaedrux I assume as I already have a working setup, I just need to add the unstable source and then the sudo update stuff. Correct?

What about the expansion board firmware, will that be downloaded with the update and then follow the update procedure for expansion boards.

Thanks.

@dc42

In preparation for its release, how would one update to a beta firmware with a duet 3 in SBC mode?

Thanks.

@pcsentinel

Can you post some pictures of your machine?

@dani

Do the pictures in my thread help? I'm on my mobile at the moment so can't upload new pictures.

I followed this blog (@dc42?) To connect my Keenovo bed. I'll upload a picture of mine later if you need it.

So I don't have experience with a Duet and Klipper but I recently configured a Prusa MK2.5S and a BTT SKR 1.4 with Klipper.

RRF and Klipper work in the same way with regards to config changes, edit a text file, save and restart for them to take effect. Documentation is a little thin for specific things in Klipper in my opinion.

I'm not sure I would bother with Klipper on a Duet if I'm honest.

@TORX_1 I have my Keenovo AC bed connected via OUT 0 and an SSR it works perfectly.

@TORX_1 why don't you want to use OUT 0?

Today I installed the 3HC Expansion Board which meant I needed a custom acrylic mounting plate and as I only had clear acrylic I replaced the 6HC mainboard plate too. Bit of logo engraving too and I'm really happy with it. Now I have multiple independent Z motors so I can adjust for bed tilt. Purchased from Ooznest.

@dc42 Thanks.
