Printer and Slicer

  • Printer: Elegoo Saturn 4 Ultra
  • Slicer: Chitubox Basic, Formware 3d.

Description of the bug

The problem is that UVTools Edit Print Parameters Tool will not let me enter speed values below 10mm per minute. Elegoo Saturn 4 Ultra with the new tilt vat hardware, needs all speeds set to 0.05 mm/min since it offers only 2 preset speeds selectable on the printer UI. When other speeds are on the slice file, the machine prints very slowly.

How to reproduce

go to edit parameters tool in UV Tools, try to enter speed values below 10mm/min. It will bump the value to 10mm/min.

Also being discussed here: https://www.facebook.com/groups/uvtools/posts/1135010564275112/

needs all speeds set to 0.05 mm/min

I found that the slicer sets the speeds and lift to whatever layer height you slice, so if you slice with 0.1mm layers it will set all to 0.1mm.

it offers only 2 preset speeds selectable on the printer UI

Can you post the that options here?

When other speeds are on the slice file, the machine prints very slowly.

Which part does it slow? The layer peel action?

How much time a peel/tilt sequence takes to complete?

On next release I will decrease the min limit to account this problem.
