Yeah great, i am a moron..
I had EEPROM enable so it overwrote the firmware settings.
so disable EEPROM if you want to use firmware settings!

I had 400 on Z-steps but LCD showed 2560 and then I realised that EEPROM overwrites it(Idiot did not see it earlier/didnt remember)

Now it moves 1=1mm

Anyways if you have 8mm leadscrews and brass nuts, and Hictop prusa i3 3dp11/12 your step settings are most likely 400
Even it says 2mm thread pitch and calculator says 1600 but you have four-start thread screw so you divide it by 4 and get 400

If you have autolevel SN04-N sensor, your board dont give it enough voltage (5v but min is 6v) and its inaccurate. I am building an resistor kit to lower the sensor wire voltage from 24v to near 5v or below so it wont fry the board. Ask if need help, I make another topic for this when Im ready with it.
