Updated Chitubox Support Settings for Large / Mid prints

Hey guys, Just sharing my current support settings in Chitubox, this is serving me well for large Moai 200 prints.

Most of these settings can be transferred to Asura if you prefer using it.

I typically use a hollow wall thickness of 1.7mm and do my hollowing in Meshmixer.

Hope it helps!

John,
I don’t see Moai 100/130 in the add machine setup for Chitubox. What settings are you using for adding a new machine for MACHINE, RESIN, PRINT, INFIL, GCODE?
Thanks

Hi Elvis, Chitubox is for adding supports ONLY. you will still need to export the STL with supports and slice in Asura.

when setting up a printer, just choose a generic one and enter in the build volume. you dont need to worry about the other settings ( which are for LCD printers )

Here is a video guide on using Chitubox

How do you find chitubox is better than ashes supports?

the software just performs better on my machine and feels more like a 3D program that I’m used to. Asura will do the same thing, so just down to what you prefer.
In the end Asura still needed for slicing.

I am using Moai 130 with default settings with PDMS and adjustable build plate and using the Peopoly Model Resin, printing at 60, 40 and 20um at 28C with the heater.

Whenever I use the models with the supports as part of the STL or create the supports in ChiTuBox (or any other program but Asura) the supports and the model come out soft. More ofthen than not the print fails.

I understand that Asura over-cures the supports, which is not happening with the supports as part of the STL files. But Asura crashes on me all the time when working with complicated model or multiple models without saving them as STL.

What can I change in the setting to make sure the models gets cured properly? Laser power (currently set to 58)? I would rather avoid changing the Asura slicing profiles, but will do so if necessary, provided someone can suggest confirmed exposure times.

Please advise.

I would increase the laser power by one and test. it sounds like you are simply undercuring

@johnchen assume both 130 and 200 use the same laser. What power setting are you using on your 200 to print STLs from ChiTuBox?

Also could you share your settings for Light and Medium supports?

The laser on the Moai 200 is actually stronger from what Ive been told.

laser power depends on the resin you are using.

I’m testing chitubox 1.6.1 with some new settings, once I get a good result I will repost. :slight_smile:

But generally speaking its just reducing the thickness and contact area as you go smaller prints.

Both 130 and 200 use the same 150mW laser.

Could you share what resin you are using for printing and what your settings look like (including laser) that give you successful prints?

I’ve switched to siraya sculpt, laser 51, works great. I am using the m200 advance vat plate.

other settings same as what I shared before.

I am using a belt heater.

here are my latest CB settings for Moai FEP vat.

Been working nice so far, start with heavy auto support at low % then add manual mid supports.

COPY AND PASTE INTO TEXT FILE AND SAVE AS .cfg and import into CB 1.6+

Thank you very much. I used your previous settings for the medium to create a set for the rest by essentially dividing or multiplying key parameters by 2 and it worked pretty well. The list I ended up with was similar to what you shared. And I had a nice and successful print with those settings at standard power settings to boot :slight_smile:

awesome, great to hear it!

@johnchen

Do you use latest Asura version for slicing the STL’s you prepared in ChiTu or do you go with the original Cure 3.5 profiles?

I have always used Asura for slicing, Asura uses the Cura engine for slicing so its the same thing, you just cant mess around with the profiles in Asura :slight_smile:
