Geeetech

Hello,
I recently assembled the Geeetech I3 Pro B, and a strange problem occurs.
If I move the extruder with manual motion via the Repetier user interface, lets say by "1" in X- or Y-axis, the extruder moves 1mm (as it should). If I move the Z axis by "1", it moves 1 centimeter!
I checked the G-Code, which looks fine. But printing is obviously not possible with this issue.
Can you help me with this?

I am using Repetier 2.1.6. My firmware version of the printer is V1.0.05.

Thank you very much for any help!

Mine is doing this after getting it hooked up. Did you find a fix?

Is it moving 10mm or 6mm? You get a 6mm movement for a 1mm input if you’ve got the wrong Z stepper value for your type of lead screw. the fix is very simple.

If you are still unsure which lead screw you have then when you have completed the installation, use the Repetier Host printer command to advance the Z height by 10mm. If it moves more like 60mm you will need to modify the GCode to change the default from 2560 to 400.

Simply enter the following codes [not the words in square brackets] into the Gcode Send line on the Repetier print page. Make sure you only use CAPITALS for Gcodes !

M92 Z400 [to set the parameter]
M500 [to save to EEPROM]
M501 [to restore what’s been saved]
M503 [to check M92 line is saved]

thank you for the reply I will make sure and check that.
