We’re planning on producing a new modified J-head hot end fitted for Bowden setup and featuring an Mk8 nozzle tip for sharper looking prints/less heat transfer.
Looking for a few beta testers, anyone interested?
#3dprinting
If it is 1.75 i will try it.
Looks like a non-replaceable tip. That might make cleaning clogs more difficult, and restricts to one nozzle diameter. Still, I can’t remember when I last removed my tip, so this may not be terrible.
I don’t have a bowden, just a PrintrBot Simple, otherwise I’d really like to try one of these out.
Good luck on the new design.
The one person I can think of at this moment in time might be @Mike_Miller . He’s been having trouble with his hot end recently on long prints and he seems to be very active in the community. Also his printer can suck from time to time, so you’re guaranteed some crashes (sorry mike!) (I’m interested in seeing if cutting out the support structures on this will affect its longevity)
@Wayne_Friedt , yes forgot to mention 0.4mm tip and 1.75mm only.
@ThantiK , cutting out the support structures was one of our concerns in making sure the vents don’t get damaged/bent, so we made them slightly thicker.
Also to mention, this bowden is designed to fit 6mm baltic birch. (not that you can’t use plastic of course)
I am interested. I have two e3d v5 and one v6, but have always wanted to try a j-head for pla. I have had some 20hr prints jam towards the end on my e3d v5. I am running 1.75 also.
sure 1.75mm 0.4mm
I’d like to try this as a direct drive on my PrintrBot Simple.
Its mount is made of 6mm birch plywood, but it’s direct drive. Might be interesting to see if it will work with direct drive as well.
@ThantiK I’m actually thinking it’s the extruder, not the hot end, causing the problem…possibly even the filament. It’s getting to the end of the spool and the filament coming off the spool is…odd…it’s like it’s twisted and tends to want to stay in smaller curves than the bowden.
I would be interested I’m building a couple printers at the moment so testing a new nozzle would work out.
I’m game too. Just beginning to assemble my new printer (last couple of parts arrive tomorrow). Planning on using bowden with a e3d v5, so easy to compare the two. Love to have a duel extruder instead of my planned single extruder.
id be game, id like to see how well it would out perform my … cough (chinesse j-head) plus i don’t mind crashing the head or letting the printer take a beating to see what its made of.
Modified Prusa I2 did i mention heavily modified…, 1.75 ABS setup. with octoprint and timelaps.
I do plan on upgrading to a e3d v6 in the near future as well. plus i have an I3 almost built.
Oooh! @Shai_Schechter , @Shauki is another one I would HIGHLY suggest sending a beta end to. He’s been using lighter flint wheels as drive gears, making his own hot ends from scrap, etc. He’s also very critical of every component and I know you’ll get good feedback from him.
Now that I think about it, I’m going to have a two head mount…I could test e3d and the beta on the same printer…
my new ingentis doesn’t have a hotend yet…
No such thing as bad feedback @Shauki
We should have a few samples on hand in a week or so. We’ll test each one first and then offer them for sale for a discounted price.
I’d give it a shot. I have a j-type now on one printer, E3D v5 on another. I bought a hexagon for my 3rd printer but the heat block bore is too small for the heater cartridge so it’s on its way back to the vendor. I could beta test this on the new printer instead.
