Leveling screws

Post by albill » Sun Dec 02, 2012 10:14 pm

I was wondering why I was having so much problem with prints on one corner of my platform. On inspection, I realized that one of my leveling screws and springs (the ones for that corner) were missing. I'm not sure that they've ever been there (might have fallen out during shipping).

It looks like it is an M3 x 10 mm screw. Does anyone know for sure about it or the spring?

All four corners should have a screw+spring :roll:

You should definatly contact your reseller or PP3DP.com themselfs via direct mail or phone. Maybe you can replace it in the meanwhile?

Good Luck

There should be three screws and springs. Contact your supplier to get a replacement.

If you try to use 4 screws, one will always be loose, three points are all that is needed to level a plane, so three screws is all you need. :ugeek:
We are talking about an "UP! Plus" right?
If you own an UP! Mini then I'm sorry but there are more problems than I want to think about with it.

If we're supposed to have three only, then how do I get the corner with the hole and no screw/spring to level? It is significantly lower, when I measure, than the rest of my platform. That seems to be why there is a hole for a screw and spring there, right?

I have three. The problem is the far right corner is lower than the rest always, even when I get the other three to the same height.

The three screws act like a tripod. So you'll need to level each corner and then keep going round clock wise to check, you might need to go around checking each point a few times, making small adjustments on each screw.

I've done this. The three corners with screws are level. The fourth corner, without a screw, is at least 1 or 2 mm lower.

yeah, i'm getting the same thing, except its one corner with a .020" difference than the others (i used a dial gauge to check it: http://www.thingiverse.com/thing:30848)
perhaps the black aluminum slab under the perf board is not completely flat?

Wouldn't be surprising. We use a plate of 1/4" thick MIC6 at work, partly because of better flatness control but also more consistent thermal properties.

Sorry, my "bad". Not knowing this section is for UP+. I have UP mini and it has springs on four corners!

We now, incidentally, use 4 screws on all 4 corners of our Up platofrms. Just makes fine adjustment a tad easier. I fully understand that, theroeticaly, 3 points is all that is needed but, for whatever reason, the 4 screws make it easier. :-)

I love my Up Plus it's been really great ... and if there is a newer version with 4 screws - I prefer 3 (I have 3 and 4 on repraps I built and a 4th is a pain). But I more was musing on not being able to have the latest technology for more than a week these days!

All the UPs and I'm 95% sure the Afina have 3 leveling thumb screws. Have you got any photos of prints?

(Old thread, but I couldn't resist...

My Coffee table has 4 legs, and it appears to be a fairly level plane :)

But more importantly, I've noticed that the platform can skew (rotate around it's center) a small amount ... that causes great issues because my Gecko clips get jammed up in there.

I've resorted to jamming a piece of plastic in there to force it to stay straight... but it's messy. And I lost a screw. (That's a darn good reason to have 4 screws to start with).

Bleh. I just had to replace my levelling screws (I lost one)... new ones come with much harder springs, platform is still prone to twisting though.

I guess now that I have more than 3 screws, I can try my own coffee table advice. But i'll not be rushing :p

BTW $85 for a replacement of the platform (which includes 3 screws and 3 springs). Not cheap.

Lots of 3 leg tables are level too ... four legs is for stability not levelling .. in fact haven't you noticed how often a 4 legged table rocks when you go to a cafe but 3 legs dont.

For screws is actually harder to level with 4 - with a four screw plane one will usually not be making full contact OR exerting too much force and introducing warp. So you end up with a bed that rocks ... or a bed that is no longer planar.

The solution to losing a screw is take out another one and take it to a fastner specialist who will supply you with an adequate replacement (go for a flat hexagon head and you can print yourself a thumbscrew cap for it)
