Oh, of course I can translate them to the English language. Will make it this evening.

It's version 1.8.1 I think?
Don't won't to use the latest version. The latest needed a new firmware for the printers when you want to use your old files again. But never touch a running system when there is no need to.

The lift height depends on the bigger size of the fep of the Saturn.
My settings are not tuned to the max, but they work well for me and that counts.

Hey Derek,
no need to translate... My PC / phone devices are all set up in English, so my Chitubox is running in English as well.
These are Christian's settings:

Code: Select all

1. Layer Height:           0.05 mm
2. Bottom Layer Count:     8
3. Transition Layer Count: 10
4. Transition Type:        Linear
5. Exposure Time:          3.5 sec
6. Bottom Exposure Time:   50 sec
7. Light-off Delay:        8.5 sec
8. Bottom Light-off Delay: 0 sec

9. Bottom Lift Distance:   10 mm
10. Lifting Distance:      10 mm
11. Bottom Lift Speed:     120 mm / min
12. Lifting Speed:         120 mm / min
13. Retract Speed:         120 mm / min
The 2nd column is where the biggest (and to me surprising) differences are. The lift speeds are near double what the default was for my Photon (70 mm / min). Other than that I see 20 secs of bottom exposure over the default and 1 additional sec of exposure time over the default.
Cheers,
Roman

It's a mix of different settings i found in some Saturn pages.
And I use 15% of softer in my resin. That needs some more bottom exposure time and generally more exposure time.

Interesting. I didn't know you could do that. What kind of effect does that have on the stability of the printed parts with a given thickness vs the 100% resin with no softener? Also why do you do that, what is the benefit of adding softener to the resin? Is it to get smoother transitions between layers or to save some costly resin? :D
Cheers,

The reason why I do that is to make the resin a bit more soft. When you try to drill a hole into it it's very brittle. The Monocure FLEX100 is able to reduce that a bit. I hope it did? Its quiet expensive.

https://3ddeliver.de/resin/monocure3d/9 ... 2XEALw_wcB

That's what I read in some resin boards and websites.
I use 15% but you can go up to 50%for a real flexible print.
They also got a real clear resin. Even after curing it it's still clear. Even after months in the sunlight it's still clear.
But it's something about 120€/l.
The grey /white resin I use for printing is cheap. Much cheaper than the filament for the old printer.
I got Resinway resin for round about 14€/Kg.
That's really cheap and work fine.

I see another reason to use it which makes sence since the wall thickness is not realy much, the solid rock hard print with usuall resin would be much difficult to allign both body parts together, there will be gaps with the usuall resin that will be hard to fill, a flexible Part only needs a strip glued from the backside to allign both parts well and glue it finaly. When using common resin i think that a print difference between the parts can not be closed easy, even with enforcing the back it might be too hard to get it together well.
I`m using a plant based resin which is hard once cured, main reason to use it is that it does not smell that much like the common used one, i pay about 25 Euro for 1L.
Take a stand!

Mhmm, have to go back to the drawing board and re-design the body and the chassis parts.
It was a stupid decision from new to cut the body on the middle of the roof.
It's so wobbly now that I can glue it together in a nice shape. :cry:
My fault!

And in this way it's also better to cut the chassis in the same place like the body. Than i know that the mounting pins will fit on both.

Learning by doing. Sometimes it's a hard way. And sometimes it's better to use your brain before you start. :mrgreen:
