Base Plate

Post by cambazz » Fri May 06, 2011 6:12 pm

Hello,

My base plate is no longer usable because one of the threaded holes is no longer threaded thanks to me forcing it too much.

I am inclined to go to the local machine shop and have an identical piece machined from steel.

I wonder if the steel base plate will be too heavy for the pp3dp?

The default one is aluminum, i can have it made from aluminum as well, but then i have to anodize it and stuff.

Any ideas/help/recomendation greatly appreciated.

Best Regards.

I fixed an old base plate by taking a few m3 screws, the "sinking?" type.
I drilled out the bit for the screw head and glued the screws in with some epoxy, together with what is left of the thread hold it in place.
I then mount it with a few bushings(?) and wingnuts.

I think a steel plate would increase jitter problems, and the normal and high speed modes would probably loose a lot of steps.

I have ordered a few 14cm aluminium plates myself, I don't bother about anodizing, don't see any point to it really.

Cheers,

Agreed - don't use steel... It probably can handle the weight, but as virtox said, it's going to exacerbate any vibration as it is a movable part.


Another alternative is to drill the hole out and tap it for a bigger screw with a bit more engagement. Fine threads are not meant for frequent screwing - so go coarse if the option is available.

That said, I like virtox's solution :)

I'll try to grab some pics.

Oh, and be careful with rethreading though, I eyeballed things on one platform and figured M4 would be an option, it's not ;-)
Unless you also drill into the heater plate :-S

On a side note:
Since I use Kapton tape as adhesive, I lost the need to remove the platform at all.

I suggest you just countersink the plate and use nuts to hold it down.
