wildBill's PG35L Direct Drive Extruder V1.1 by wildBill83 Jun 14, 2012

Description

Wanted an easy swap extruder that would use existing vitamins and clear the threaded rods on the end of the x axis.

V1.1 includes many tweaks and fixes compatibility with 1.75mm filament and mk7 drive wheel.
Currently works with my generic drive wheel, blddk's drive wheel, or MK7 drive wheel.

Mini-hyena version coming soon!

I printed this out and am now using it. It works great. I was using a different PG35L type extruder and had constant problems with grinding and shredding the plastic. With this design I'm not getting any grinding and it's also easy to check everything. Thanks and nice work!

How far away is the mini-hyena version, as it's still says 'coming soon' a year down the line? Thanks

Cool it how?

Instructions

SEE PDFs for detail.

I'm never looking back on a Wades extruder, this thing prints so nicely.

TO BE DONE: Clear BOM and clean up prints.

Source is SolidWorks 2011 zip.
IGES and STEP added so other CAD systems can play along.

Print either the 1.75mm plate and fan shroud or 3mm plate and fan shroud. Fan shroud does not print well with two outlines and was removed from the plate.

See me printing with version 1.0 here ustream.tv/channel/reprap-wildbill

Can you provide an stl for just the idler? I would like to print the 10mm hotend derivative version.

Never mind, I separated it in netfabb.

Has anyone managed to get this extruder to print good quality with 3mm filament?

Im using the 3mm version of this extruder with a makerbot mk7 drive gear and a J-Head hot end (0.35mm nozzle). I have been using this for a while now and the prints that it produces are very accurate (holes etc are exactly the correct size) but it stops extruding randomly, missing whole sections
out and ruining muli-hour prints which is very frustrating..

The stepper motor does get very hot, which i suspect is why it fails, but i have upgraded the fans - even to the point of having 2 fans either side of the motor (tried both blowing onto the motor/one blowing, one sucking etc), but i just
dont think that this setup is able to feed the filament with enough pressure to extrude correctly. I was previously using a wades extruder which work flawlessly up to 100mm/s, although the prints it produced were not very good accuracy wise (holes etc were always about 1mm too small!).

Does anyon
e have any ideas about this, because i love the design of this extruder and id love to get it working well.. I was hoping that is would be able to print faster than the wades i was using as it is much lighter but so far i havn't had much luck! :-(

are you cooling the peek of the j-head extruder?
With PLA printing you need to cool the j-head.

Just saying thanks- this thing is printing some freeken amazing quality stuff.

Where's the best place to find the motor (link if poss), also the driVe gear.. does blddk haVe a site? this looks great! I am itching to get away from the geared extruder.......

NewPerfection on Aug 22, 2012 said:

You can get the drive gear from MakerBot, or ask blddk in the #reprap IRC channel.

wildBill, the Mini hyena you are designing for is it the 11x5?

Thx,

feher on Jul 10, 2012 said:

This is an extruder I was looking for! Needed one with motor aligned along the x-axis, not perpendicular to it as other designs.

I took a liberty and modified it to work with mini-hyena 5x8 and one small drive bearing 5x8x2.5.

Will get back here once I have it working.

Sounds good, glad you found it useful.

wildBill83 on Jun 24, 2012 said:

With v1.1 you can also mount the motor 180* for more z clearance. I'm going to reprint this today just for more clearance. :)

Awesome, gonna print this out and give it a try. Not real happy with the Trinity labs one, and this one re-uses the vitamins I already have. Very nice design.

wildBill83 on Jun 22, 2012 said:

mounting the toggle bolts in reverse from the drawing may be easier for maintnenance.

wildBill83 on Jun 21, 2012 said:

Update 1.1 will be out tomorrow with many minor fixes for small annoyances and compatibility with mk7 drive wheel.

wildBill83 on Jun 22, 2012 said:

Update 1.1 is out for 3mm and 1.75mm filament and mk7 as well as some other fixes.

I got my I on this 8-)

MiseryBot on Jun 15, 2012 said:

Nice! Two ideas:

1) over-center tension lever?
2) mirrored version for dual extruder applications?

8-)

wildBill83 on Jun 15, 2012 said:

I'll do an over-center version, those require a 624 bearing usually, the goal on this thingi was to create something using existing vitamins from a wades or greg's. As far as the duel extruder goes, I think it should be a single housing duel motor solution. More to come on that later :).
