Dragon burner + beacon + ebb Merc Toolhead

[lucid basin]

Dragon burner mount for my Beta Merc. Using a beacon probe, ebb 42, and a omron micro switch for end stop. Only thing ive modified from the standard dragon burner files is the front cowl to allow the beacon to sit closer to the nozzle

Still a few quality of life changes to make before im 100% happy with it. Any feed back is welcome because im sure ive forgotten something

[celest flower]

Might want to look at yavoth too, while there. Should be more rigid

[lucid basin]

I'll double check but that should bolt right on. The ducts might be in the way of the beacon though. I'm trying to keep the beacon in the suggested spacing limits

[lucid basin]

Done. Just need to fit belts and wiring

[lucid basin]

Waiting for hotend to arrive then I'll release the files

[crystal marsh]

Looks really interesting, finally a toolhead that can be removed without having to remove the belts

[lucid basin]

I'm a fan. It looks super easy to work on. Just gotta finish wiring the rest of the printer so I can test it

[crystal marsh]

Which parts of the dragon burner were changed? Only the cowling?

[lucid basin]

Just the ducts had to be changed so I could get the beacon closer to the nozzle. And added the logo.

[toxic wave]

I thought about putting the Rapid Burner on one of my Mercs since I have a UHF hotend with a Sherpa Mini and Nitehawk36. Very curious what you think of the Dragon Burner once it's working.

[copper cloak]

But this needs the eva carriage mod on the dragon burner, right? or it’s not a mgn12 on top?

[toxic wave]

I believe either an EVA style mount for MGN12H, MGN9 or MGN7 carraige on top, or using the Stealthburner Xjoints to mount the rail on the front of the gantry. Am I wrong, @lucid basin?

[lucid basin]

I didn't even know there was an Eva carriage mod for the Dragon burner. You're right that it's like the Eva style mount. I wanted to keep everything close to the original BOM as possible. So mgn12h, same endstop switch. And kept the rail on top so no need to modify or change X joint and still use the ultra light gantrys for the Merc

[toxic wave]

So which mount are you using on your Dragon Burner?

[lucid basin]

I made it

[toxic wave]

AH I see. Got it.

[lucid basin]

Haha

I'm just making a mount for my screen then I'll finish the wiring and see how it goes. I do like the dragon burner though. Super simple design and easy to work on

[ripe arch]

Looking forward to hearing how it turns out, have a bunch of parts in the mail to finish Merc as well as convert my v0 over to Dragon Burner. Kind of like the idea of running it on both rigs.

[lucid basin]

I find the wiring part boring so I've been putting it off. I'll have to stop procrastinating 😅

[toxic wave]

Well, I've been torn between trying Rapid Burner or the Yavoth since they are so similar. So hearing anybody's feedback would be great. 👍

[lucid basin]

ill have to double check if they fit with this mount. Might need to modify the bottom of their ducts if you want to go beacon

[copper cloak]

ohh, nice, have you uploaded the stl/step files somewhere? I can’t find them here

I was also looking at the rapidburner, and maybe this is compatible with it

[lucid basin]

I can upload the stl, but other than bolting it to my merc, i havent really tested it

To me, it all looks great, except for the end stop switch

Im trying hard to make this compatible with everything from the bom and main files, but i think i might have to just make a new endstop block

[ripe arch]

Happy to test fit anything if you want to throw up the STL. Orbiter/RapidoHF/Cartographer on an (untested) E34M1 here. No endstops.

I ironically love wiring so taking my time on the electronics bay right now lol

[lucid basin]

Love the colours youve gone

Im pretty happy with the files. Ive still got to make an endstop block which mounts to the top of the x carriage. and i want to make a cable bracket that will mount to the top of the tool head carriage. thought about adding it to the file but it just made printing the parts harder

Ill upload the step files once i learn how to clean up the absolute mess my work flow is 😅

[ripe arch]

Nice! Loading them up in the slicer shortly. I've got an EBB36 mount with a cable gland top mount, not the most compact solution but it was something I didn't have to kludge up in FreeCAD lol

[lucid basin]

I might whip up a back plate with no mount for those who don't need to mount an ebb there

[lucid basin]

Endstop block made

[ripe arch]

Looking good! Waiting on some parts to ship in so I can wap over and try it out

[lucid basin]

I've gotta a couple more parts to print for my beta build then I'll be testing it out printing

[lucid basin]

Rear of carriage with no ebb. so blank. then you can use the tool head board mounts that have been designed for the dragon burner

[split shard]

Was looking for this exact thing, awesome work

[oak surge]

was this with the V7 or V8 dragon burner?

nice work, btw

[humble quarry]

This looks like exactly what I’ve been looking for, and somehow just noticed it. Thanks for uploading your files!

[lucid basin]

V8 I believe. It was the most recent

Sorry. I hardly check this unless someone pings me

Still going strong. I did move the toolboard to the back of the extruder. It was dumb on the back

[oak surge]

double checking the heat set locations. Should I have some in the yellow locations?

and if so, do you push them all the way in?

[lucid basin]

@oak surge Hey mate. I just ripped the front off to show you. Bottom two for beacon. Then those top two pushed all the way in. I did that so I could use common size bolts and not have to cut anything down.

[oak surge]

Awesome, thank you! I was going to also ask how you terminated your belts but you photo shows that too.

I really appreciate your models. I'm nearly set assembling it and apart from those questions it's been smooth sailing with a DB v8

[lucid basin]

No problem! I was going to work on a prettier way to lock the belts in, butttt the cable ties have never failed so I found no need to fix something that isn't broken.

[oak surge]

FYI, for the carriage front, I found that it was around 0.9mm too large in this dimension when mated with the V8 dragon burner

I'm just printing a spacer to go between the extruder and toolhead mount since that seems like the least-time-consuming fix

and certainly something could be off for my DB parts

[lucid basin]

Interesting. I'll have a look at mine when I get into work tomorrow. I can load the file up in fusion and add 0.9 for you?

[oak surge]

oh, no worries. the shim will be a lot less effort for both of us 😄

thanks, though 😄

[oak surge]

any chance I could trouble you for the CAD? the spacer ended up working out well, but I also ran into some wire path issues for the LED wires, where I didn't make them quite long enough to path around the carriage front. I think if I trim off these two corners, it should clear up the routing and also make room for the zip tie mounts to be used

[lucid basin]

Ofcourse. Gimme a min.

[oak surge]

any chance you you have a link to that toolhead board adapter you're using, too? the one that corrects the angle off of the stepper?

[lucid basin]

ill see if i can find it. its made for a voron

https://www.printables.com/model/316984-ebb36-mount-with-cable-strain-relief-for-the-orbit

[lucid basin]

i also pm'd you the step file. soz its a mess

[oak surge]

thanks! I'd been struggling to find an adapter but I'd been searching for the wristwatch g2

[lucid basin]

should work. though it looks like the stepper sits a little lower on the wwg2

[oak surge]

OK, here's the trims. I added the trim that makes the spacer unnecessary.

[red glen]

Hi, I’m a bit confused with all the different Dragon Burner revisions. Could someone explain the differences or tell me which one I should use for my setup? Thanks 🙏

[copper cloak]

it depends what’s your setup 😅. this is to use on a mercury one with the rail on the top of the X axis extrusion. the original dragonburner runs on vorons which have front face-mounted rails. I think you can also use that on the mercury, so it all depends on your liking

[red glen]

Which is the best for the mercury one ?

[red glen]

I’m little bit lost in this

[copper cloak]

Top rail it’s what the merc was designed for, but it depends on the toolhead. There are setup that makes front rail perfectly fine. If you use the front facing rail with the stock setup, and a toolhead straight from a voron printer, you’ll have a slight misalignment close to the edges… but I’d stick with the default and rail on top. This toolhead is nice and compact, makes use of 2 4010 fans on the side instead of a single 5015 on the back as in the eva toolhead. Also this supports beacon that’s not supported in the stock eva2 toolhead

[red glen]

Ok I think go for the side mounted like this one:
https://www.printables.com/model/457167-dragon-burner-mgn12h-mount-with-and-without-klicky/remixes

I plan to use voron revo piezo, no beacon

[meager skiff]

@lucid basin heyo, to use this i just need to add official hotend and extruder mounts, correct?

[lucid basin]

By official you mean dragon burner official?

[meager skiff]

correct

[lucid basin]

Yep. I can't remember what version dragon burner o used but it was the latest at the time when I made it. It's been working perfect ever since so I've changed nothing

[meager skiff]

gotcha thanks!

yeah i'll probably switch to this as the e34m1 doesnt really have horns that work with the Dragon Ace and Beacon

at least with shorter nozzles

[lucid basin]

I'm using it with an orbiter V2 and micro Swiss bambulab flowtech hotend with an ebb mount to my stepper motor

[meager skiff]

the beacon either hits the bed or the horns point right into the heater block

[lucid basin]

I did my best to design it to work with standard dragon burner files so if there's any upgrades to dragon burner my files would still suit

[meager skiff]

curious about the EBB, can you hook up the beacon directly to that via USB? or whats the deal there it seems neat
