Custom button in Pronterface, down 0.05mm?

I am rather new to 3D-printing and I would like to add a custom button to Pronterface that make the effector of my delta go down 0.05mm every time I push it.
This is for helping me to calibrate it properly so it needs to be relative movement, meaning it must work both in the center and at the edges.

I have 0.9 degree steppers and 16 tooth pulleys so it should be able to perform the step physically.

I agree, 0.1mm is too course. I use 0.05mm all the time, which is a standard option on the web interface supported by RepRapFirmware, and I now find I need 0.025mm. I no longer use Pronterface except for debugging, but it is coded in Python and I've patched it before, so it shouldn't be too difficult to change. In the version of Pronterface on my machine, to change the Z movement amounts it looks to me that you need to change lines 27 and 168 in gui/buttons.py, and possibly also line 1468 in prconsole.py.

If you just want a button to move down 0.05mm, first go to Settings->Macros and define a new macro containing the following commands:

G91
G1 Z-0.05
G90

Then click on the + sign and the bottom of the window to add a custom button, telling it to invoke your macro.

Thank you!

I'll go for the macro and custom button because I feel I need the "Down 0.1" as well.
