Extruder flow.

Hi, I've changed extruder on the ender 3 pro and mounted a Redrex, all ok besides the Wisamic 4mm glass plate. Re-calibrating.

In simplify 3d set nozzle diameter 0.4 multiplier to 1 and extruder size equal to the nozzle.

Result, walls from 0.23 to 0.25. Average 0.23. I do (0.4/0.23)x 1 and I get 1.73.

I change the multiplier and enter 1.73. Reprint.The walls are still 0.23 to 0.24.

Panic...

Thank you

That's off by a lot, perhaps you're nozzle is clogged or not actually .4mm. Try a different nozzle if you have one.
