In configuration.h find this line:
#define DEFAULT_MAX_FEEDRATE {500, 500, 5, 25} // (mm/sec)
And change Z feedrate (the one i made bold) to somewhere between 3-5mm/s depending on how fast your motor can go.
It could also be to low current setting on your z-axis driver. If you drive two motors you need more current on Z-driver.

Can i use Teacup on a atmega328 to drive a uln2003 darlington array and a unipolar stepper with normal step signals and not dir/step/enable?
with 2 or 4 wire control like this
Thanks

The ending g4vs is a customer kode. I.e for special axel, gear and so on. I know this because i work with copy machines and they use alot off the same motors but with different gears on. :-)
So don't think about the g4vs.
If you look here u see that your motor is a 400nNm in unipolar setup and 500nNm in bipolar. (they should be hybrid motors as all others) :-)
Some fine motors
