G'day Satoer,

Thanks for the design, just installed today. with this carriage design and the e3D hotend printing at higher temps i.e. abs @ 270. What speeds are you able to print at with good results?

Also what fill do you recommend printing these at? 100%?

Stephen...

Hi Stephen,

Usually I print at about 140%, sometimes when I'm in a hurry I print at 200% speed. But to be honest, I don't think it prints that fast (especially more complicated infills). I think at some point the printer prints as fast as possible, or maybe it's a firmware limitation. Also, I don't know how fast 140% is (in mm/sec) it's just relative to the slicer settings.

Also, I design things with 3D printing in mind. I try to avoid bridging and floating surfaces. I rather go for a two piece design than the need for support. Anyway, another "rule" I use while designing 3D printable objects is rounded corners. If you use rounded corners you can print much faster. And designwise, the object looks nicer, but that's more a personal taste.

Dear satoer

I'm in search of another hotend because my version 4 hotends on the Dual 3.0 are allways jamming. (The problem shouldn't be behind the machine, my V3 hotend was working perfect for a year ;) I thought about designing a single head direct drive with the e3d v6. Would you recommend that Hotend? I'd like to have a reliable one for high quality prints.

Cheers Marco

Hi satoer,

I'm retrying your hot end mount with a new V6 now, but it seems I'm getting backpressure and the plastic bowden fitting on the lock/release mechanism pops out.

I'm not sure if I need to adjust the flow/feed rate ??? any ideas ?

I can manually push the filament into the hot end and I'm currently at 220.

It's o.k. bed was too close to the print head, had to recalibrate. All good.

First print going and it's looking good.

Would love to know which slicer people use.

Actually, this is still a problem.

I think it's due to the 5v fan not cooling the hot end enough.

Do people use 12v for this hot end ?

EDIT: I can see satoer does use 12v.

I'm using kisslicer pro (the beta -relase) and I use 12v for this hot end.

I used 12v for the original hotend(s) too. After several days of printing, the hotend-fan
stopped working because of a defect on the electronic-board.
I switched the hotend-fan to 12v. No Problems yet. (But significant more noise - sigh).

Upgraded to 12v and still getting backpressure. :-(

When the backpressure starts to occur I can see the hotend is extruding much thicker filament too.

But I'm at 230 degress now with PLA.

I've always used my fans at 12V and haven't had a problem
