News by Master NaKo that has tested the theory. Kudos Master
:)
So this can work out of the box without any messing with the Gcode.
Will probably void your warranty. since you will need to solder header pins into the Z pinout in the board unless you buy some pogo pins that i do not advise
:P
The driver he tried is a LV8729, but any step/en/dir type driver will do.
To use the driver without changing the config.gcode you must set your driver to 1/16 setps that in most drivers means connection ms1/ms2/ms3 to 5v
I advise tinkerers to buy a extension board like the one i post a picture of and avoid protoboarding all together, you can get these for 1 euro on ebay
Connection schematic comming soon check the video of the machine printing with the driver in a breadboard gangsta style way
:)
Thanks NaKo for ginea pigging and sharing results
;)
The correct math for the original reference value is (Motor Rating) 1.5A x0.8 ==> 1.2v (reference voltage) so anything between 1.0v and 1.2v should be ok
