Tired of my delta printer...

peirof

Hi,

I'm tired of my delta printer....

The last thing is that another duet board has fallen, and it's the second... I've decided to start over...

He look for kit recommendations for corexy.... Not long ago I asked, and they recommended a Voron0, because I was looking for a small size.... But when my main printer dies, the idea is a corexy of 30x30x30 cm print volume.

Recomendation for a corexy (aprox 30x30x30)... I have see time ago, that some of that kits, you can order Duet... I am interested in that...

Thanks in advance

One of the current popular and very capable printers is the Voron 2.4.

It is a CoreXY but with a fixed bed (the XY gantry moves in Z).

You can get kits in different sizes - I've seen 250x250, 300x300 and 350x350.

Everything I've read says it is a great printer.

@peirof RailCore. Found my voron2.4 unreliable. Stripped and sold it.

I know a number of people running Vorons and are struggling, mainly because of the SKRs or BTT and Klipper combo.
It just does weird things. Z offset fine one day, next it is either digging in the bed or too high.

RailCore imo is the way to go. Plus there is less plastic parts to print and they can be upgraded to metal parts.

@peirof Maybe one of these?

I have no experience other than a SeeMeCNC Delta kit I got years ago and updated to Duet and just keep printing with it.

@peirof, Voron are well designed printers. If you want 300mm corexy they have Trident (latest design, series 1) and Voron 2.4 (slightly older design, series 2). They are both good, well documented, complete designs (e.g. real cable management) and can be enclosed enclosed (in case you also want to print ABS and the likes).

The default configurations are Raspberry Pi + Klipper firmware + Chinese boards but you can use whatever you want (I use Duet5+2 standalone with RRF and it works well for me, but people with Klipper and new boards such as Octopus or Spyder also seem to be happy.).

They also has Switchboard which is a corezx (bed moves in y direction).

The recommended way is to purchase individual components yourself based on the sourcing guide and configurator's output. There are Aliexpress kits that can work and recently good quality kits are starting to emerge (e.g. LDO for V1, Trident and V2.4 in next few months). These kits don't include printed parts (should use ABS or ABS+, not PLA, ABS, or anything else) so you can print them on your current printer (enclosed it somehow), order from the Voron PIF program or from sellers such as on Etsy.

Here is Thomas's opinion about his V2.4. He didn't enclosed it, uses duet, and some high flow extruder but same V2.4 frame and movement. https://youtu.be/0E0dM0ZdpRE

I have built a Jubilee ... so far I am quite happy with the way it turned out but it is still early in the process for me. I decided to go with a 4 tool changing setup but it should be easy to only use one tool if that is all you want. It is a bit awkward to enclose for higher temperature printing but it is doable. I used Filastruder as a parts source for most things - perfect one stop source. Excellent build instructions.

The Trident is newer than the Voron 2.4?

And the bed moves on Z instead of the XY gantry?

Thanks.

@fcwilt, yes, the Trident is a newer design.

V1 and V2 mean Voron1 or Voron2, as in a product line rather than a version. It's a common source to confusion hence the move to real names such as switchwire and trident.

The main differences are that trident has a bed that moves up/down on three leadscrews while V2.4 (version 4 of Voron2) the bed is static at the bottom and the head moves up/down on 4 belts.

There are theoretical pros and cons for each but the general thinking is that they have about the same material capabilities, speed and quality and the difference is a matter of personal taste or 'coolness'.

Here is the Trident announcement https://youtu.be/Be4GaSCAGU0 , the guy at the bottom left is the Voron founder.

@zapta the main problem, its I cant print... My delta, its out of service.... I have see some printed kits....

The idea its scrap my delta and use some of the components in New core xy printer...

@zapta

Thanks much.

@peirof another option is the BLV MGN cube. You can get kits on Aliexpress that are reasonably complete. It also uses a Duet WiFi by default (though all the kits will come with cloned boards, but you can get them without the board and buy a proper one)
The design and documentation might be slightly less complete than the Vorons, but I think its a slightly simpler machine which might be easier to setup.
Either that got go for a complete printer out of the box e.g. an Ender 5

I'd start over building a new printer only when I've found the reason for the Delta to grill Duets.
If it's lack of knowledge or some misunderstood documentation, your next project will fail, too.

Sorry, if it sounds harsh, but I'm trying to save you some money..

@peirof Have a look at the Rat Rig V-Core 3

@o_lampe

think you have reason....

It is the great fear that I have, that I mount a new printer, and that for something that does not do well ... I will burn a Duet plate again ... But the other option is almost worse, if I change the Duet plate, in my current one printer, without changing practically anything ... I'm condemned to fry another board ... and I don't know how to get out of that loop .... when the Duet v2 board arrived, I was happy because it had more fuses than 1, and I thought that he was protected ... but apparently it wasn't enough.

My biggest fear, mounting a new printer, and burning another duet board again .... but I DON'T know how to deal with the problem

engikeneer

@peirof main thing to do is to test. Get a multimeter and test all your connections. Check for shorts to ground, shorts to Vin etc.

Reading your other thread, it sounded like you had a short somewhere in your hotend wiring which needed diagnosing and fixing before the Duet was powered up... even if the Duet has fuses, they take a (small) amount of time to blow so won't always protect your board from that kind of damage

I haven't seen that thread, but another where a Duet1 board has a burnt driver chip. The error seems to be in wiring/electronics mishaps.

Available in different sizes from 200x200 up to 500x500. All metal design.

Thanks to all...

For the moment I have 2 preselected printers:

Rat Rig V-Core 3
Voron Trident

Its easier purchase Rat Rig components...

Some options of those printers?

Some options of those printers?

I would say, stay away from bowden extruders, go with direct ones.

My 2c.

peirof

I'm studying the options, for the moment I think I'm staying with the Ratrig...

Maybe I like the idea of the Voron better... But the configured Ratrig website, makes getting the components much easier than the voron.

I have a doubt, after using the configurator, I do not know if you have tried it ...

And it is that when choosing the board gives you the option of Duet v3 mini (it is the idea I had, for that perfect face) but adds:

Duet 3 mini
v1 WiFi with Duet v3 (I suppose I guess this will be to add WiFi to the duet 3 mini)
Dual steppers expansión board (Ratrig uses 5 steppers motors, duet 3 mini have 5 drivers... Why this expansión board?)

Someone can give me feedback about these printer?

Thanks

zapta

@peirof said in Tired of my delta printer...:

Ratrig uses 5 steppers motors

It's possible that they use 3 independent Z motors? (+ two for X/Y and one for extruder) and thus needs the expansion to drive the 6th motor.

The 'V1' is the version of the Duet Mini5+ Wifi. Github shows two versions, 1.0 and 1.01. Not sure what the differences are.

I think it depends a bit on what material you want to print. Do you want to print ABS/ASA/PC then you'll want an enclosed printer.

I would recommend a Voron for that, a Trident or the 2.4. Yes, the 2.4 has some challenges, it has a flying gantry and four z-motors but it's very well designed and together with some mods it's a print-and-go machine. It requires that you understand it though, it's not an Ender 3.

As with all enlosed printers that get's a higher chamber temp you will have heat expansion that can be a problem if you don't understand it. It can be handled with Auto Z-correction and mesh compensation with large prints. Or you always print with the same circumstances.

The community is large or rather getting huge, though we are a fewerbunch using Duets but it works really nice with the 1LC toolboard. Just four cables to the toolhead. It is though an DIY printer for people who want to build a printer themself.

Tuned it can produce great prints. Small example in ABS (greatly enlarged. It's about 3 cm across):

If you want mainly a PLA-printer I would go with maybe another machine, open frame or where the enclosement is more of an afterthought.

I see, that you have a Voron....

How did you get the materials?

Did you take the BOM from the web, and you were buying them separately?
Did you buy a pack? Web?
The printed parts ... did you buy them, or did you print them?

As I have said, I like the Voron more, but finding the materials to make it seems more complicated, although I already have part of them ...

@engikeneer said in Tired of my delta printer...:

Get a multimeter and test all your connections.

I have started to build me a little teststation, where I test all electronic components before I use it with a Duet:

endstop
steppers (with Arduino and Pololu)
SSR
hotend circuit
wires with crimping (I've still problems to crimp)

So I know that the electronics are ok (no short circuits, right poling) before I "set the Duet under danger".

Gixxerfast

@peirof I bought the parts from mainly a couple of sources, Fermio (DE), Lecktor (EE) and AliExpress (Powge and Trianglelabs and a few more). Then a few bits here and there and the Duet boards from Denmark.

I built an Ikea Lack enclosure for my Ender 3 and printed the first parts on that in ABS/ASA. Then I have reprinted most parts on the 2.4 itself as I have modified it.

Yes, there are so many now that want Voron parts, but checkout the Voron Discord there you will get heap of info, almost too much A very friendly and helpful bunch https://discord.gg/voron
