Bed centered cam mount for taz 6 ???

Post by nuroo » Tue May 30, 2017 7:30 pm

Those are what I've found so far for the Taz 6......
Pi cam bed mount

(Pi cam quality isn't so hot, even version 2 pi cam, and footage will be off axis. No Gopro mount)

Z-axis bed mount

(You see the bed moving during the whole time lapse. Big models will not be centered in frame. In my opinion this type of time lapse is ugly)

(Bed doesn't moving during the time lapse, looks like a sky scraper building not a jerky mess. Model is centered through out build. Gopro quality is much better looking than either pi cam version.

Does anything like that exist for the Taz 6? Center mount would ideal for time lapse's.
Here is my current video https://youtu.be/B2rQmlee4g
Shot with an Gopro positioned in the center of bed but not attached to bed. I just dont like the look of this footage.

Try this: https://www.thingiverse.com/thing:949219

Mount attaches to the aluminum plate under the bed. You'll need some M3x5mm screw to lock the swivel in the correct position. Optionally two more M3x5mm to lock the mount to the aluminum plate. M4 screws and nuts will be needed to lock the arm in place.

I use a logitech webcam with my Pi these days, but with some adapters you can use a GoPro.

Didnt fit. Not enough clearance between build plate and the metal sheet underneath it. Maybe I could sand a few mm off.

Hmm... Ok, I lowered the top a few mm.... 3 to be exact. The top looks pretty thin, so you'll probably need the two M3 screws underneath to clamp to the aluminum bed.

Let me know if that works out. Pictures would be great for further modifications.

Thanks for taking the time to mod stl's.

This is the part you sent b4. I filed it down to fit. Haven't printed the new version yet. But i can tell you it needs to be between 4.7mm-5.0mm thick to fit between build plate and metal plate. I will try version2 tonight.

Considerations:
*In current form it will definitely hit the mount as the print head moves along during a print or bed leveling routine especially. Even with a shorter arm it's just to close.

*As you can see from the pic the clearance under the mount is very tight, I'd be worried it might hit the screw at some point. (I could move it a few mm to the left or right :cry: )

Suggestions:
I think the mount needs to be longer horizontally to clear the print head. Something that extends the mount farther away from the bed. But then the concern would be if it sagged too much hanging off the bed and hit the screw. Would need a design thin but rigid enough to not sag from camera weight.

The footage above was taken with the mount below
www.thingiverse.com/thing:2206950

It's attached to the left washer of the bed, so you at least don't see the bed moving. Since its angled on the bottom the print head clears it no problem. Just hope we can get something worked up for the center of the bed.

Let me know how V2 works... I may have shaved it down too much if it only needs to be .3mm. I can always increase the thickness.

With the extra cooling fan at the front of the print head, I can see how the toolhead could hit the mount. I put mine on the right hand corner, away from the X0 Y0, my prints rarely reach that corner and it doesn't interfere with the mount Y-axis endrail piece. Does the TAZ 6 autolevel pattern hit that corner?

I can extend the mount, but will probably need to make the bottom thicker... welll, here's the updated version. I extended the mount 30mm farther out. Give it a shot.

Make sure to get the v13C file... I may have uploaded the wrong file.

Yes the taz 6 touches all fours corners during bed level calibration.

Printing v2 now. I will report back...

v13c 's clearance between the heat bed and the metal sheet is a good fit.

1st pic is a shot of Taz6 auto leveling on first washer. Then it travels to the opposite washer along the out side of the hot bed. v13c is still in the way as the print head travels across the bed.

I must put v13c off center or it will hit the big screw as the bed moves along the y axis.

v12b just barely miss's the big screw shown above as a reference. So v14d needs to have 1mm or -0.5 less height then v12b
v14d maybe wider
v14d extender farther away from bed.
v14d clamp part that hugs the bed, make it longer under the bed too
