Welcome to the SeeMeCNC Community

That's awesome! Looks super clean! Some of the other setups and results I've seen are nothing compared to what you've got running there.

That looks awesome. I'm assuming you used ABS for all the mounts? Seems like PLA that close to the nozzle/heater cartridge would warp really quick due to heat.

yar it is orange abs, you could probably get away with PLA, i would just wrap the heater blocks with insulation first.

alrighty so i have replaced my temp solution for the dual ezstruders with this.

It fits in the standard holes but i had to drill 2 for the filament to feed down. i am also using some of those filament spool rollers using nylon drawer wheels

Nice job!
Would you still have the stl for the dual ezstruder mount?

i have a tiny revision i need to make before i share stay tuned

ok here ya go

Alright so with dual extruders comes....printed then dissolved support material.

I've always been curious to see just how clean the print comes from the dissolving.

Looks like you've got things pretty figured out with the dual setup. That cube looks pretty tight!

Awesome that support looks fake in that image like it was photoshop'd for some reason , maybe thats because its kinda floating off the object , either way cant way to see the cleaned up version. And whats is it btw , spiked helmet for Doomsday preparation , lol. Hmmm.

Alright so an update to this cube.

i had found some 95% tech grade d-limonene locally.... and after 4 days this is the progress

I think the fact that its 95% TG, instead of the recommended 97% FoodGrade has a little to do with how slow it dissolves, but what is having a more direct affect is the fact that the supports were printed as a solid instead of a typical support structure. The rammus i showed in a earlier post should disolve much faster because of the ammount of exposed surface area of the HIPS.

or this f16 that is about done

I assume you're going to hand finish the rest! Looks very cool. You're a pioneer!

Looks like a great way to add and remove support structures without damaging the part.

Hey Bubbasnow,

This may seem like like a strange question, but have you noticed a difference in surface finish/alignment/quality when mounting the E3Ds under the print carriage like that?

I seem to remember getting really clean prints before I upgraded and mounted the E3D underneath the print carriage. Now my external perimeters aren't quite as clean as they were before. They're not bad, but they're not perfect anymore either. I'm trying to track down the cause.

I'm going to remount a single extruder high in the carriage again to see if that's the cause. If it is, I guess I'll need to design another carriage where I can mount the duals high instead of low.

i have not seen this, but i can see how it could be a problem

I think that this may be the result of the gimbaling effect of the effector platform. If the platform can we wiggled about the vertical axis the centerline of the extruder can be made to rotate in a slight arc realitive the the part Z-axis.

If the tip of the extruder is on the face of the platform (not practicle from a clearance srtandpoint), the rotation occurs about the tip and there is no side to side motion since the radius to the tip of the extruder is essentially zero. If the tip is moved away from the platform the radius increases and the side to side motion for a given angle of rotation increases.

This may increase the alignment error or maybe not. On second thought just ignore this post and strike it from the record.

Actually nitewatchman, that's what I've been wondering.

Knowing that every discrete position is only an approximation, there's going to be a small error in every position and movement, and any error in position or angle of the effector plate would be magnified the farther away you get from the carriage.

I suspect that for every motion there is a very slight tilt one direction or another, which wouldn't be important with a standard mount, but would stand out more on the low mounted hot end.

I'm going to switch back to a single extruder high mount and see if I notice a difference. I should be able to get to that this week.

I'll print out a pair of parts with the same settings and compare.
