Z Steps

[adamfilip]

im running into an issue where my models are shorter then expected

when I measured 100mm ends up being 96.31mm
so i was trying to update my Z steps

In Marlin i set it to 6400 steps
but when I connect to the printer, the feed says the following

Steps per unit:
M92 X80.00 Y80.00 Z12800.00 E541.06

Why does it say 12800 steps if i set 6400 steps in marlin
using 1/8 microstep

is it just doubling it since its not using 1/16 micro?

i tried setting it to 3200 steps and it still shows up as 12800

Do you have eeprom enabled? Could be remembering the last settings instead of pulling form the configuration.h file.

M502
M500

I did have eeprom enabled and I think this was the problem. I didnt realize that with eeprom enabled I needed to do M502 & M500 after i flash
i only adjust files in marlin/flash i dont change stuff via the lcd

Thank you!
