after uploading firmware Z Axis moves very very slowly Hictop Printer

dmkmedia

I uploaded the Repetier firmware to a hictop prusa i3 and the z-axis settings in the old firmware from marlin was 

#define DEFAULT_AXIS_STEPS_PER_UNIT   {80,80,398,94.4962144}

398 being the Z axis now everything else seems to work on on the firmware once uploaded apart from, the Z axis when i try to move in any direction it just very slowly pulses and turns  very very slowly

I have tried ZAXIS_STEPS_PER_MM  set at 80, 398, and 2559 but nothing on any values apart from different kinds of slow pulse turning

can anyone help me to find a value, please

my origonal firmware was https://cdn.shopify.com/s/files/1/1671/6015/files/Marlin_3DP17_398.rar?6195037615555381895

Repetier

Check eeprom value for z steps per mm.

where are you on about ? 

Repetier

In repetier host/server you can edit fimrware settings in a function called eeprom editor.

Did you run the eeprom clear sketch 1st (in arduino examples) this will clear any old marlin values from the eeprom
