Re: After-market extruder head

I finally got this thing working. Due to a minor oversight I had to turn a right hand extruder into a left hand. It snags a little now when first feeding in the filament and unfortunately they don't make a left hand version of this particular extruder. I may try find an alternative extruder that has...

Re: After-market extruder head

I got the drive unit done and I think it might actually work! 8-)
Now I just need to find some time so I can finish the printed pieces and try it out.

Re: After-market extruder head

Wow, that’s awesome and great news! I would prefer to use cube print, I’m not too concerned about fine tuning anything right now. I’ll just start simple, change the extrude head, match the speed and see what happens. Thanks!

Re: After-market extruder head

my software works with the native cube prints Tim, excuse my ignorance but I'm not quite following you. Are you saying I could change the speed and still use the cube print software? Just so I understand, you use S3D to create the g code file, then your program takes that file and modifies it to wo...

Re: After-market extruder head

Hey Tim, below is a breakdown of all the parts. I've added another piece which was missing in the earlier picture - the hub that interfaces with the cube. Basically, the original cube drive gear mounts inside a set screw hub, that hub bolts to another hub that mounts the 5mm drive shaft for the extr...

Re: After-market extruder head

Alright, I got busy with some other stuff but I'm back. Here's what I have on the direct drive option: Direct Drive.PNG I still got a couple of details to figure out but it's pretty much done. Now I have to figure out how to change the speed. I know some of you have gotten simplify 3D to work with t...

Re: After-market extruder head

Hey Tim, Thanks, I'll keep that in mind about the backlash - I suppose with retraction that could be an issue. I'm looking at using more purchased parts (gears, plates, etc.) instead of printed parts which may work better. I can get all the hubs and gears I need from Servo City for relatively cheap....

Re: After-market extruder head

So here's the diameter of the hobb goblin:

That number compared with the 9.6/9.7 I measured on the original cube gear is the ratio I need for the gears (I think). But it may take a few tries to get the speed right.

Re: After-market extruder head

And yeah, I could make the middle gear smaller and even put it off to side slightly

Re: After-market extruder head

Yeah, I saw those. I'm thinking maybe getting the extruder assembly and one of those and swap out the feed gear.
