Summary

thingiverse has become sad place where they can steal your work and patent it.... nothing to see here

Instructions

This is new version of my extruder print it without support, layer 0.2 in infill 40% or more. it's working nice, to use with idler from thing:18379 .
You may want to flie slot for hot end a bit (i didn't need to but i made stress test this way) it's still not perfect but I will send update some time later.

idler is from standard wade extruder eg. http://www.thingiverse.com/thing:18379http://www.thingiverse.com/thi... block plate is for blocking Jhead mount in extruder body wedge so it's secured in place

I'm extremely confused... what am I supposed to use for an idler block? I see no way of fitting the "block plate" to the extruder body...

I made a new derivative from your last version as couldn't find editable files for yours. http://www.thingiverse.com/thing:169372http://www.thingiverse.com/thi.... i hope you'll like it. if you see some possible improvments i'll gladly take your suggestions in account. ^_^

well there is STP file, and you could ask of other format file anyway cool design. I don't use Wade style anymore my printer has vertical X rods. Feel free to improve my design. I have new version of this extruder but haven't time to test it so i didn't upload it. Think is time to add new version

yep, there are step file but it's not easy to make modification, i started it all over.
what program did you use to make the original file?

yes it has nut traps and holes for normal carriage

Nice extruder, it's still usable on a standard (50mm bolt, non quick-fit) x-carriage?

I'm liking the j-head mount, is there a version of the standard extruder with that wedge fitting? I'd like to shrink this a bit, it looks like it is 100mm overall and that is going to make my carriage too long, any chance you could post the files in STEP format?

tell me if that export options were correct it was deafult so i can change something check some other options

Yes perfect thank you.

The rounded corners I refer to are the 4 corners on the bottom of the extruder, compare with http://www.thingiverse.com/thing:18379http://www.thingiverse.com/thi... to see what I mean.

My big gear is also from jonaskuehling http://www.thingiverse.com/download:59456http://www.thingiverse.com/dow...

You say it didn't work? what is the problem, I want to use this in the kits I am selling but don't want to waste filament if you already know it doesn't work.

Greg's Wade reloaded - Guidler, Tilt Screws, Fishbone Gears

the problem was with filament hole it was to close to hobblet bolt, i have this thing designed from scratch so i don't have print errors like with other extruders, i have repaired model, but my printer is constantly braking so i don't have time to check it, i can get those corners round, i got most corners now round that should make J head mount stronger. if You want to test new model i can send it, i will not print it till next week, having just one printer is pain

Really good idea, is it a Greg's Wade's Reloaded (ie. http://www.thingiverse.com/thing:18379 Tiltable screws etc)?

Greg's Wade reloaded - Guidler, Tilt Screws, Fishbone Gears

If so it should be a derivative and I will definitely be using it, if not you should alter it.

Okay so I answered my own question by viewing it in Meshlab. It is indeed a tiltable screw version but I see it is not exactly like http://www.thingiverse.com/thing:18379 . I recommend rounding the sharp corners as well as changing the supports to be like http://www.thingiverse.com/thing:27054http://www.thingiverse.com/thi.... Sorry I cant work out how to make a link in the comments.

I will pm with the same suggestions.

modified Greg's Wade reloaded jhead parcan

I had http://www.thingiverse.com/thing:18379http://www.thingiverse.com/thi... and got most of design from it, I will put it in derived. I curently redesigning it because first one simply doesn't worked. Tell me what is your big gear diameter?

Greg's Wade reloaded - Guidler, Tilt Screws, Fishbone Gears

the harringbone gears require a taller extruder body. 4-5mm added to the bottom of the extruder body sets it high enough the hearingbone gears do not hit the x carriage

Could you tell me which corners need rounding? Well for me it's more of taste thing than strenght since it's 3d printed not milled.
