Sorry everyone, for some reason my model was inverter. I uploaded a new one (Extruder v4-2.stl) that should be corrected

SO i bought a jhead as an upgrade to my MIX G1 printer but found i could not get it installed.

I used the above mods on mine and its printing wonderfully!

This is the modification to the MIX g1 extruder to accomidate the jhead. (use with my modified X Cartridge)

following change

Opening for the hotend enlarged to fit the JHEAD hotend

Holes added to allow 2 screws to hold the JHEAD hotend in Place

Body made bigger because my hobbed bolt was missing the filament because it was going to far.

Depth made a bit smaller to allow the same screws to work (due to the elnarged back)

Added a mounting hole for Exaust Fan (next project)



So you need a modified X Cartridge that creates a bigger opening to the J-HEAD.

If you already have a MIX G1, the screws you used to join the two parts together will work tine (I used the same hardware).

Just line up the holes from the X Cartridge and the Extruder piece here. Screw them together. (you do not need these to hold the hot end in place if your using a J-HEAD)

The J-HEAD simply fits into the whole. Use two screws into the screw holes at the front middle of the extruder to keep the head in place (they dig in slightly into the JHEAD keeping it snug)

Can you post an assembled picture of your mix g1 so I can see how you have it setup using the two files?

Uploaded photos. But basically it the same setup as a normal MIX G1 Extruder. Top Down screws just don't hold the Hot End in place, they just join the X Cartridge and the Extruder together. The two screw holes in the front hold the JHEAD in place by screwing in to the notches in the JHEAD.

Let me know if you want full instructions on how to put together the Mix G1 Extruder.

thanks, started printing :)
one thing I noticed is its printing flipped, the tensioner is on the left side instead :)

I will have to reverse my stepper or it will extrude backwards, since this will go on my ramps mixg1 it will be easier than the baboi controlled mixg1 I have

Very weird. the software i use for some reason inverted the model or something. I actually had to mirror it WRONG in the software and export it and now it seems to be correct.

But yeh all you will have to do is reverse the E stepper and it works fine. The back of the cartridge and the extruder wont line up properly either but tats just cosmetics. I uploaded a corrected STL now it should be better. Sorry!!

Also hint: the WING NUTS have to be parallel to the Z axis, otherwise they hit the Z smooth bar when homed (from experience)


do you have a link to the hobbed bolt or sleeve for the stepper you used?
i didn't order the original one from mixshop for this printer and other ebay ones i tried so far don't grab the filament well enough due to them being smaller diameter than the original one

The original designer of the printer/extruder no longer has this on their site but the place i got mine from still does. Here is a link where you can even order it online (or if your local pick it up in person :))


Note: The x cartridge is also now compatible with the WADE RELOADED extruder.(i added mounting holes for both extruders with jhead support) I printed one but am just missing the hardware to try it out!
