When I run "Extrude 100" from the 2004 Smart Controller Panel, I get a filament feed of exactly 50mm. That consistently results in excellent prints. But why do I need to use 50mm as the target rather than getting 100mm?
Hardware setup is Titan extruder (3:1 ratio), 1.8 stepper (200 steps), 1/32 step driver, MKS 1.4 board/Marlin.
Marlin extrusion settings: steps:829 (to get 50mm exactly from "Extrude 100"), max feedrate 100, max accel 10,000, retract accel 2000, Ejerk 5.
If I set steps at 2x829, extrude 100 just blasts out filament way too fast.

Where in Marlin is the line that sets the Extrude 100 parameters?

New at this, and did forum searches and looked thru Marlin config h and h advanced but can't find relevant settings. Thank you.

The "feedrate" value sets the maximum speed the motor runs at. Reduce that value down to slow things down.

The steps/mm has to be right (2 x 829 for your extruder I guess) no matter what other settings you have.
