We're working on some ball sockets for 10mm steel balls to mold inject them. Magnets are cool, but mold injecting is a cheaper method in the long run and insures the ball has no play in the socket. These will snap onto 2mm thick steel for ease of assembly. Thoughts?

If you want to have some "light" reading on ball manufacturing and precision kinematic design, see http://www.precisionballs.com/
Plastic sockets may start with "zero" play, but they will wear.  The snap fit features will affect roundness, as will the rate the part is cooled in the mold.  You will always get play or flex, key is knowing how much you can live with.
As you measure finer, everything turns to jello.

Yeah. Nobody prints anything bigger than "tiny" with it. Because you need a heated chamber to do real prints.

Free Printrbot (beta) v2 extruder... You pay shipping. Limit one per customer.

https://printrbot.com/shop/plastic-extruder/

This will be put into production on the Play soon but wanted to give the community to play first. I have used it and like it a lot. I will enjoy offering the cheapest solution out there very soon... And it does work with flexible filaments. A fan is recommended for whatever hotend you have- it is plastic after all.

Quick question / comparison with your experience: If you print very low layerhights e.g. smaller than 0.05mm, do you also need to raise the flowratio very much?
Currently, I print a thing with 0.05mm and my flowratio is 120% compared to 0.2 or 0.1 layerheight...

If you have to adjust the flow rate that much, the your extruder is not calibrated very well.

I didn't know they're that big. Honestly, I grew up in Pennsylvania mountains... Never heard of them till I moved to Toledo area of Ohio about 15 years ago. I honestly thought they only did groceries. Anyways...

What about getting a kit? Do you feel yup to building your own? I think my next one will be in kit form because I'm getting past the fear factor of breaking it.

This is by far best prints for me, as for surface quality without z-layer artifacts

I've troubled over eliminating z-layer artifacts though it was not too much.
Basically, I designed current printer focusing on rigid z-stage to solve it.

Until today, I didn't make it despite of all efforts.

The last tweak was REWIRING every motor cable to be braided AND
REROUTE 12v power line to RAMPS to follow every wall of the frames.(make it far away from other signal cables as far as possible).

The result was very successful.
I guess interference by12V cable caused stepper motor get corrupted signal and it leads to unexpected layer movement.

I was silly that has not thought serious about importance of cabling.

Gah Some sort of under extrusion problem. First layer is fine ( about .2mm off perfect but S3D handles the offset fine) once it gets to second layer or more it starts under extruding.

Current Settings :

215C
60C Bed
85 mm/s print ( half speed bottom, 2/3 speed outer peri)
E3D Volcano PT100 @ .6 nozzle

What I've done to try and fix:
Cold Pulls : nothing of note
Replaced Heater: Previous one had a short and blew though 3 fuses till i figured it out
PEI Bed: Tried taking it off( printing on just glass) - No improvement)
Reapplied PEI - Thats what you see now.
Tested Ext Motor holding torque - once engaged I cant move it at all by hand

Not sure were else to check. My current guess it the Rambo board ate it on one of the fuse blows, or the Z stepper has a tendency to get crazy hot but hasn't presented any issues ( unless this is one)

So anyone got any ideas?

+Mr covert , thanks for that info on Aldi. Their sale price is $499, which is truly outstanding.

They are also selling 1kg spools of PLA for $35.

The printer looks good, but how do you know it's an i3 variant? They make no mention of the design derivation, its just called the Cocoon Create...

Tell me! What printsurface does PC stick on? What is your experience?

The thermal expansion coefficient of most pc mixtures is bigger than abs. The thermal expansion (and there by contraction) is what causes warping. Think pc is to abs, what abs is to pla.

It is probably a pain to print

Guys have you seen the prices of SLA Resin. If you could afford the SLA printer , the prices are crazy. I think I stick the filament.

I think application for molding jewerly, SLA would be good choice. But still lack of polymers that can be used various usage.

I would like some advice on overhangs.

I've tried printing this model from thingiverse:
http://www.thingiverse.com/thing:1220231 and it does not turn out very well.

I've tried printing it at 190Deg with PLA, and Fan running 100% (half the fan points to the heatbreak, and the other half on the model).

The problem is that the bottom sides (with supports on CURA), are terrible.

It seems it's melting too much and hanging.

Any advice on how to fix overhang issues. The problem is especially evident when printing anything which is spherical. The bottom half of the looks like an old wrinkled lady, whereas the top half is as smooth as a baby's bottom.

I would be greatful for any advice

Im using Repetier 1.6 and having a problem with Slic3r. The print is loading fine, but after slicing in Repetier the print preview is blank. Even tried reinstalling Repetier but getting the same results.
