E3D releases v6 - their latest all-metal hotend (Page 3 of 3)

I got my E3D V6 yesterday and here are some of my impressions.

I was able to assemble everything fine from the video instructions.  I was very paranoid about damaging the thermistor because I had never done that before, but I was able to get it installed well enough.  I might order another the next time I get something from filastruder because I could stand to clean up the wiring and make the heat shrink neater.

I got wardjr's V6 mount printed before starting, I used 0.2mm layers and 100% infill.  After finishing the installation, I tried a test print.  After about 8 frustating tries, I was never able to get more than a minute to two into the print before the filament would jam at the top of the hot end and start curling between the hot end and the extruder drive gear.  Everything was right in my installation, so I figured I need to cut a piece of the PTFE (luckily, I got the bowden version) and mount it between the drive gear and the hot end.  This seems to have solved this problem.  Tip: the PTFE needs to go all the way down into the heat sink.  Remove your tension arm, slide it down into the heat sink as far as it will go and use a knife to cut it very close to the gear.

The E3D V6 hot end is running like a champ!  However, I am getting some significant wobble in the mount.  It is firm along the X axis but wobbles along the Y.  That being said, it is still very usable and I am getting decent prints but there is room for improvement.  Here is my first test print: (imgur because I still can't figure out how to post pics in the thread).

Wardjr, thanks for the mount.  Since you are welcoming feedback... I think we need a version that has a locking arm.  I think the corners could be just a little sharper and this might be helped with a firmer mount that has a locking arm.  There is visible wobble in the hot end with every retraction.  I know I got a good print of the mount so I don't see any issue there.  Tip: mount the hot end in the mount before screwing it into the extruder motor or carriage.  It needs that little bit of bend to get it there and taking it on/ off while it is in the mount seems to wear the "snapping" edge, leading to more wobble. 

Personally, I'm looking for a mount that will hold the hot end in with two screws with trapped nuts.  I know that is a  lot of stuff to cram into a small space but I think it would be the best way to go. 

Here's a thanks to filastruder for quick shipping.  I ordered it on a Tuesday with priority mail and had it by Friday.  Next up is a T-glase test and continued searching for other mount options.

Also your images are set to private, and to embed you simply put the (picture, not album) URL inside [i mg] [/i mg] tags (remove the space).

I added the .skp to the original post so feel free to change anything you want.  As far as locking arms and wobble I am guessing your printer failed to produce a dimensionally accurate part.  Since I haven't even looked at my v6 (still in box) I just really can't say.
When I go to print one I will do it at .3 and 100% fill as I can see no value in a .2 layer height.  I am sure there's room for improvement or even a total redesign.  Since I run a Bulldog XL on my main printer and my spare printer is happily running a v5 I have no real motivation to make changes (other life priorities) right now

Can you buy the modded MK5 that works with the V6 from your store? I need 2 new v5 parts and I was considering just upgrading to v6 but I can't print out the Modded MK5 for the E3Dv6 since my printer is down.

His supplier has been slacking

i am having great difficuly in getting the nozzle to fit without bending the mount piece.  It is strange because the holes that are for the screws connecting into the stepper motor align perfectly. ive taken a caliper to it and the dia of the circle on the mount that locks the hot end into place is 11.54 whilst the hot end itself is at 12mm. i could try and print it at a larger scale but then im just gonna run into problems with the stepper screws.

Does anyone have the mount as a solidworks file? be so handy cause then i can just modify and reprint. otherwise gonna have to measure the whole mount and build from scratch

This probably means you are over extruding. Have you calibrated your printer?

Okay, I have finally designed, printed and tested a version of the mount that uses a bracket to hold the hot end extremely tightly and eliminates all wobble.  Here it is, I welcome any feedback.

Hey Tim, do you have any inside info on whether E3D will be updating the Kraken to the v6 style therm/heater spec?

Excellent!
I may get on that in the not too distant future.
