General Discussion / Re: Alternative slimmer shim

« on: June 03, 2016, 04:43:40 AM »

I I clean it with the spray for electrical contacts, both the shim and plate

This does not solve the issue, I never heard about someone cleaning plate and nozzle like that when printing without a shim.

I tried the thickness gauges for mechanical, they are metallic and conductive, but do not work, surely the electrical resistance is different

Maybe a translation issue, but the difference in electrical resistance between different metallic shims (different height/metal) is IMO not even measurable to the sensing circuit since the wiring resistances tolerance is even higher.

It's about contact resistance, Julia showed a mechanical way to optimize this.
I use the following setup for non conductive beds, it ensures an optimal shim to bed connection.

Verbatim PLA is special. Some spools require a shim, some not. I didn't find a rule yet.
In other words: You have to test the correct shim height.

Best to use is a feeler gauge like this: https://en.wikipedia.org/wiki/Feeler_gauge

This one can be disassembled and one has many different heights available.

Bed level is also something that has to be watched BTW!
I bought two V2 perf boards lately, that tend to lift in the middle.
That way the bed varies by 0.3 from the center to the outer edges.
If your print consumes large raft area on such a bed and you use a shim to further lift the nozzle, you're on the loose.

By the way, this "Pro Matte" filament is in fact Polywood. I should get some...

Looks like ZT-HE sales performs great, that filament is $116 / KG.

That's a cool print!

One thing I remember now: This filament on the M200 likes rounded surfaces. Flat plates with some structures on it tend to produce stringing.

Yes, I used a shim. Raft and support removal is tricky also (needs to be cut off mostly).

yes, I think that was the reason :-)

I do not remember any raft issues, if you heat the bed try lowest position or switch it off.
You could also try a larger shim (0.6 - 0.7mm).

I checked it, it is the same: https://www.igo3d.com/en/neutral-transparent-innofil3d-pla-1-75mm.html

The English page names it transparent, German article description is 'natural transparent', label on spool is 'natural'.

printed on ZT-HE at 0.29, unbelievable surface (almost no visible layers), great haptic, very lightweight.

Julia, among the materials I tested with the ZTHE protytype there was also Inofil PLA natural wich is IMO the same as transparent.
It could be printed without issue, 240° is definitely too high. the spool was rotting over a year in my closet.

Prints are not nice because Inofil is no high quality PLA filament to me (ABS might be better).
