Topic: Davinci 1.0- Z Banding

Had very little surface banding when it was new. Now, severe banding.
Measured banding and by golly it almost equals thread pitch- 8mmx1.25.

The right stationary Z rod bronze bushings are loose in the plastic bed frame. I can wiggle the bed sideways.
The bushings are ok on the rod.
The left side of the bed frame encloses the bushings entirely , while the right side is open. :rolleyes
Whats that all about ?

I used a sml pair of vise grips and clamped the bed to the left of the bushing and it took the looseness away.

How do I do a permanent fix ?

Re: Davinci 1.0- Z Banding

If I print too fast, I will get banding or ripples in my object. I use the 20mm cal cube from thingiverse that has an X and a Y made into it's sides. On the Y side I get what looks almost like Echos of the the Y from one side of the Y to the edge of the cube. There are about 4 of them. Still not sure what causes it as they don't appear using XYZ crap ware.

Printing since 2009 and still love it!

Re: Davinci 1.0- Z Banding

I'm not sure if it was on this forum or the Voltivo site but this issue was addressed. If I remember correctly, you can shim the right side with paper/plastic shims to snug it up. Some folks may have also used an adhesive like lock-tite to attach the bushings to the plastic frame.

Re: Davinci 1.0- Z Banding

Ive done the shim trick on the Y rods w/ cut up credit cards. Circles and holes are now round-amazing.

Loctite alone will not take out the Z bushing play in the bed frame.
There is a good amount of movement.
But I may be able to curl a plastic shim around the bushing along w/ loctite.
Also, when using adhesive, it must be free of grease to stick. Alot of grease around the bushings to clean

How do you post pics on this forum ?  Tried posting pics but had problems.

You can purchase a 'kit' from wctek with washers and glue. He has an awesome video showing how to fix it.
