@Solv777 others answered everything sorry for late reply.

Yeah, basically you set it as single part (or batch of them... let's call it part, just for the sake of simplicity) in slicer, then you set that to be printed with multiplication tool. That is set similar to a single tool definition, but you'll set additional tools like T4 to be a duplication tool (for like front two), T5 to be a quadruplication tool..
You place your part to be printed in the middle of the bed and firmware will take care of offsetting and multiplying it based on offsets set in config.

You've probably found "Marx group" on Facebook. I've shared my configs (top most post, links to google drive) ; https://www.facebook.com/share/qNYUQoUD2tn3p4hP/

As for slicer, you can use whatever you're comfortable with as long as it can inject stard and end g-codes.... So really whatever you're fond of most

As you've got the info above, you can stop specific one of the head printing using extrusion factor, should one of the copies fail during print.
I've even printed TPU, PLA, PVA and PETG in one job, each copy being it's own material since one can use individual Pressure advance factors on each individual extruder. It's a long ago. Was featured on one of E3D's facebook groups/pages.

Also, set both left toolheads as one tool and both right toolheads as one tool. This will enable you to do a duplication of dual material printjob. Because you can.

@o_lampe ya ya ya, “build it right”… agree.
Still, as those wise words go: we can not build machines perfectly precise, but we can make them precisely adjustable.

Hello,
is it possible to do meshbed compensation not by the means of Z axis but with using a separate mechanism incorporated? Or is meshbed compensation bound to be done through/with Z axis ? @dc42 @jay_s_uk anyone?

and if possible, is it doable for like an IDEX machines, while printing ditto job, that each head would individually actively compensate. Especially now that multistream gcode capability is becoming a real thing (respect on that achievement btw)

thank you

@oliof thanks .
Wont lie: A lot of thinking went into concepting and construction on both of those.

@oliof here are some pictures and videos on google drive. Google you probably have

and this is somewhat more ambitious build, quad markforged mockup XY plane, but awesome life happened to me so making it proper and metal is on hold:

Hey @Pyper

I guess this is too late of a response but i will put my 5 cents in anyways regarding this topic.

I made my daily workhorse merging 2 cheap IDEX machines. Just 2 X-gantries on a bedslinger, one on the front and one on the back, shared Z but 2 independant motors driving it to assure gantry level. X gantries both have linear rails. When built right (parallel linear rails!), it’s easy to use. Tool 0 has a fixed mount while other 3 have a height adjustable mount i came up with.
There are many that say this is crazy and unreliable. I made it and it works. Probably people that dis this approach should first build a machine like that

My main goal was to have one machine for big output of mostly jigs and fixtures, adapters, etc for what FDM is great.
While it does work for multimaterial, it’s not my gig. If at all, i use secondary supports material.

So yeah: Very doable & very price performing results.

I am not that active here last months so joining a “Marx group” on facebook ( https://www.facebook.com/groups/237163797566846/ ) will give you access to my repository and a more direct help if needed.

@aitor very sorry to jumping in here… but…a 10 individual head machine? 10 ?! what kind of hellfire is this?

I am walking this path for a while now - an IQEX… in process of building a new one, based on what i’ve learned in past 2 years with it.

To start I used cheap i3 style IDEX (Tenlog D3 was my choice), threw out crappy boards and did height adjustable toolmounts (very important). Used Duet2 + Duex5. Then just doubled the IDEX axis and viola, got IQEX… at this point, i use one as IDEX and one as IQEX. Daily.
So this is totally doable and huge advantage when you want high output.
What you want is take time and assemble the thing VERY precisely. Everything square and BOTH X rails EXACTLY parallel and square to Y and Z. Not a huge challenge, but I for example didn’t think of this when building first time.. fixed that, learned something. Making a jig on which you assemble the X gantry so that both X linear rails sit flat and then you torque everything up helps a bunch.
Whoever relies on meshbed levelling is doing stuff wrong. Yeah it’s nice, but you tram the machine and level the damn flat bed. Then you print on it with absolutely no problems day in and day out.

Disadvantage: with i3 style, Y axis is only one so while you can do multiplication, you can only mirror in X direction. Not huge disadvantage & still has better output at the end of the day than any “i printed a benchy in 10 minutes” gimmick. Machine is not realistically encloseable tho.
Works absolutely fantastic for about 1000 bucks printer.

What i am doing now is a box design - so XY plane is moving and bed is on the Z. It uses (well it will eventually) 2 stacked double markforged kinematics. Something similar to Muldex printer, but doubled.

Is it worth it? Not really sure. Should be fast as hell compared to my current i3 IQEX. More silent for sure. Encloseable. Insane output. Etc. Still, if concept works, then i will have to scale the design up to like at least 600x600 mm buildplate so this monsters electronics and build price are justified.

If this triggers your heart, i do posts from time to time on my FB group (“Marx group”. As in Marks’ group, not in marxistic way )

@dc42 DOLD mechatronics sent another 3HC board. It now connected and updated instantly. Under a minute job after i got replacement.
Now to figure out this M669 for quad markforged kinematics matrix stuff.. not sure if excited or scared down to the bones.

Maybe see ya in another thread I think i'll make something like this for my signature when 1s, -1s and 0s are in place

M669 K1 X1:1:0:0:0:0:0:0:0:0:0 Y1:-1:0:-1:0:0:0:0:0:0:0 Z0:0:1:0:0:0:0:0:0:0:0 U0:0:0:1:0:0:0:0:0:0:0 V0:0:0:1:0:0:0:0:0:0:0 W0:0:0:1:0:0:0:0:0:0:0 A0:0:0:1:0:0:0:0:0:0:0

Thanks for warranty.

@dc42 thank you. I've let it sit there on 12 volts for 2 hours. then 2 hours on 10 volts. it was 2 hours on 24 volts before so... sadly, no luck with booting. The other one with a newest bootloader is ticking like expected. Thanks again.

@dc42 i ask for warranty approval.

@ja cabels are well made. Swapped them. No change. Reordered and also used only that one board. No change. Shuffled addresses. No change.

Since DIAG led is not lighting up even a bit, yes, i would have to load a bootloader. That can be done via CAN bus, or, if for some strange reason you get your bootloader *ucked up out of the box, theoretically with Atmel ICE. Which is a 125 eur device that you then use one time on a 125 eur board.
But yeah. Agree 100%

@jay_s_uk run it on 24 but i can try 12v... i could revert, but the DIAG led should at least do something whatever firmware it has. or not? funny thing is, the board that works has serial ending 71, and the one that does not has 69.
Anyways, not doing this because it should work. does not. I'll RMA it. This is why i bought original not cloned.

@jay_s_uk latest beta. 3.4. beta7 but that does not matter. The board, even new, never blinked DIAG led - it does not even boot i guess It acts totally differently now that new bootloader is flashed.
and since I can not connect the other non connectable 3HC via CAN, i can't easily flash bootloader on it unless i buy a 125 euro programmer for it. It's real bummer. The only good thing is that i bought complete movement set, one expasion was an easy fix, so in time i finnish building XY plane (for that i only need 6HC and 3HC) the replaced board will arrive and i'll connect Z towers then. Hopefully.
And i am pretty sure I am not the only one that got the bad bootloaders. So people that just can't get it connected: it's not the firmware, didn' even got to that, it's basic bootloader.

@maracmb sorry if you took it that way. I know you're not affiliated. I know you tried to help, and that is greatly appreciated.

Flashed the bootloader on the one that works. It now connects CAN immediateley. And DIAG led flashing. As it should. Out of the box.
The second one i guess just has bootloader corrupt out of the box as suspected. No diagnostic indication, just sitting there.

I am NOT paying 124 eur for Atmel ICE. This is absurd. I'll just RMA it. Indefinetly if it need to be. Shame on you Duet3d!
No usb cable supplied, corrupt bootloader, not even basic 1 eur straight through CAN cables... just a shame at this price.

@deckingman you can have 17 extruders but this duet 3 is still an overpriced, out of the box underequipped, non working... thing.
Serials are practically sequential. and one works, one does not. so it's either bad distributor or vendor that does not do QC.

@deckingman i am unable to update the firmware on this 3HC. Setting to zero, resetting, nothing. Repeating.. nothing.
Updated firmware. Nothing.

Docs: "unless bootloader is corrupt..." what if it is corrupt?? i probably got some returned board that someone bricked or something.

@dc42 @Phaedrux does one have to repeatedly turn this stuff on and off to get it CAN connected?

@theolodian it’s not that much really. I plan on using same principle as Multiple motors on one Z axis…but for Y
So only XUVW YA Z
7

But yeah i’ll update either way.
