Jigsaw Replacement mk4 (Page 3 of 4)

I can clearly see that mk4 is superior desing compared to current jigsaw ... only question now is - in witch colour to print ?
Good job guys - i see now future in my solidoodle.

I've just updated the tensioner arm file.

The new one is more robust , moves the bearing into slightly better alignment vertically and horizontally (should get better grip and drive) and should be marginally easier to print.

I suggest anyone having any issues with the the grip on the filament try this update.

Lawsy, I wanted to personally thank you for saving my butt with the mk4 this weekend.  I got my first clog when the extruder fan stopped turning unexpectedly, and I noticed that my jigsaw looked to be in bad shape when removing the peek to unclog it.  Once I was back up and running, the first thing I did was print the mk4.  Good thing, because when I unscrewed the jigsaw, I found that it had many internal cracks and it fell apart into a zillion pieces. 

The mk4 is an immeasurably better design. The only thing I might try to add is some sort of soft brush (toothbrush head?) to clear abs dust from the gear while it prints.

So I am working on installing this right now and I have a question about the nozzle, what exactly is the point of the piece of wood and do i need to keep it on here? also why is there a small piece of acrylic on it? it gets in the way trying to install and i just want to make sure it is okay to take off or what to do with it before i go on. thank you for the help!

I just break those off.

Will lifting of the corners during the print significantly affect fit and finish during installation?

I find the wood piece useful for levering the hot end out of its relatively tight fit, and back in again (potentially while hot) ... though I did have to break off about one eighth of it to make the hot end fit in the mk4.

Maybe someone near you can print the parts, were do you live?

Impulze: I'm in Ohio, specifically around the Toledo area.

Nlancaster: I have an SD2, had it for a few weeks now. I thought I had my first clog and might have to take apart the jigsaw. but after some poking around with wire and a few filament changes and a readjusting of the tension arm I was able to get a test print out of the thing. So I might be able to print my own (crosses fingers).

It would still be good to know where to get one if like me someone didn't plan ahead.

Thanks Gordym,
I think I was able to clear out my clog, and I've got an MK4 printing right now. But I do appreciate the offer, and I'll keep in mind how close you are in case I break anything in the future.
