Re: 6-lead steppers: lower current = more torque?:S

It seems, the inductance in full torque config ( 2.1A/1.9Nm ) is to high for 24V. The torque drops pretty fast at higher RPM .
I made some travel speed tests and with a pulley gear ratio of 3:1 max travel speed was ~200mm/min ( 6400 steps/mm )
Then I changed gear ratio to 1:1 ( 2133.33 steps/mm ) and got +400mm/min travel.

I'll try the 3A/1.35Nm config with 3:1 gear ratio tomorrow. IMHO this will be the best compromise...
