Script to pause or lift to a certain height each layer

[MakerMav]

I am wanting to do time lapses and would like to have the build plate move to a certain height and pause for a couple seconds to take a picture of each layer. Is that possible?

It's possible with GCode printers and CTBv3&4(i think), but you will also need hardware to capture it still position and inform the camera to take the picture.
Will be easier and time saver if you picture the current position after UV LED turn off, there are one or two mods for saturn for example

The hardware I have figured out, and have been taking pictures when the LED is on. But I would like to capture an image with the built plate in a raised position. It is a Saturn I am working with, I just have no clue where to start with coding a script to modify the .ctb file in UVtools.

It took me less time to realize I can convert it to a ctb zip, open the zip, edit the actual gcode file, rezip, and convert it back to the encoded ctb.

Wont work for your purpose.
CTB dont run gcode, when converting back UVtools will interpt the gcode and make a static table, a extra movement on gcode converted to ctb may mean a wrong position or discard that move, i dont recall what i made on that step. But i can tell it will not work...

[MakerMav]

Yep you are right. I've been racking my brain trying to find a way to get this to work and I always hit a roadblock with the file format. I would be more than willing to reimburse you for your time if you could create a script for me. I really don't have the time (or mental capacity) to learn a new language.

[sn4k3]

Yep, no way to do it manually... You need an automated way, and that is via programming.
And yes, can i do it for you.

[MakerMav]

I appreciate it. Just let me know what you need.

best if u are using a saturn is to use the network protocol and make a script to pause and move the plate to the defined height. maybe adapt Master photonster Lagnajeet's photon EOS timelapser https://github.com/lagnajeet/PhotonTimeLapse No dia quinta-feira, 20 de janeiro de 2022, Tiago Conceição < ***@***.***> escreveu:

The script: https://github.com/sn4k3/UVtools/blob/master/UVtools.ScriptSample/ScriptTimelapseSample.cs
Note that you currently can't use the "Blank layer" option yet, UVtools checks prevent malformed positions, but i can add a extra check to allow this situation on the next patch.

For now test if it work with lift height, i recommend CTBv4 for this

[sn4k3]

Winner!

Nice! I will optimize few more things and i then i can submit the patch

[sn4k3]

You can test the last release

[MakerMav]

First test looks good. I'll let one go overnight for a full test.

[MakerMav]

Sorry, my printer blew a transistor and was down several days until I got a replacement. The full test went great, and everything worked as it should. Here is the result.

Ok nice to see it works well now :)
