DeskCNC Controller/driver

[rogerbureau]

I want to run 3 PowerMax 11 stepper motors with the DeskCNC 3 Axis Intelligent Stepper Motor Controller (35 VDC max 2.0A 8 Microsteps/Full Step
Step up at HALF stepping

The motors P22 NRXC-LNN-NS-00 are connected in bipolar
Specs are: 200 Full step/revolution, 2 phases.
Rated Current/Phase is 1.55 amp DC.

I use a 24 VAC power Supply with a with a built-in 2.0A Slow Blow Fuse.

PROBLEM: (Power down betweem each connection)
1- Power up DeskCNC recognize the Controller
2- Connect the X axis MOTOR and JOG it many time no problem
3- Connect the y axis MOTOR and JOG it many time no problem
4- Connect the Z axis MOTOR , at POWER UP the Controller LED was not ON and DESKCNC could not recognize the BOARD.
5- I check my POWER SUPPLY and there was only 10 VAC output.
blow the 2.0A Slow FUSE

Can I use a POWER SUPPLY with a higher CURRENT RATING with that Controller?

Thank you
