My controller consists of four Gecko 201's and my power supply is 30 amps at 36 volts FWTW. The filtering can be more, but, not enough is not good. As already stated proper amperage is required.
A few tell tale signs are as follows.
IF the amps are too low the steppers won't move, if the amps are border line they will skip, if the amps are too high for the stepper
they will work fine until they get hot and then they can act very strange and unreliably. I get reminded of this since i switch different setting resistors depending on what machine my controller is used for.
You can lower amp requirements depending on how the motors are wired ( if its possible), but, then that's a trade off of stepper preformance.
But the 10 amp supply may still be marginal.
Do contact Gecko about the inductance isssue Hood brought up and reply back on what they said.
