PrusaSlicer with custom DLP 3D printer

Hi, 

I have a custom 3D printer. Before I was using another software, but it is giving a lot of errors with my UV projector.

I made my research and found PrusaSlicer is the best option available, so here I am.

 

Although, I am having problems with the settings and configuration. How should I relate the UV projector and the Z-motors in the software?

Thanks

Most of that is done on the SL1 itself. The output of a SL1 slice is just a config file (JSON if I remember correctly) and an image for each layer. You can certainly adjust the exposure times and print volume in PrusaSlicer as needed for your printer, but you would have to adjust the printer's firmware to understand and work from the SL1 file (it's just a ZIP file).

But I don't have the SL1 printer. Should it work the same way with my own UV light projector and my Z motors?

I'm building a custom 3D printer.

The SL1 file is not gcode like for FDM printers. It only contains the information about what needs to be done, not how to do it. It would be up to your firmware to interpret the file and do the correct things.

The config file in the SL1 bundle tells the printer the layer height being used and the exposure times. Your firmware needs to then do the correct things with the projector and Z motor. Then it is just a matter of displaying the correct image at the correct layer.

Start off by slicing some object for the SL1 and then unzip the resulting SL1 file. Then you'll be able to get a better idea of what is there and what your firmware has to do.
