Re: Replacing Syil Stepper Driver With Other driver. No Luck getting motion
Typically each input has 2 pins. Internally it is a LED with a series current limit resistor.
The pins are labeled + and - apply 5v to the plus and ground the -
Usually you connect all the +'s together, and drive the -'s to 0v.
I have seen some drivers that MUST have enable powered as above, else the motor is free.
Done this way, if the 5v part of the system fails then the motor is not powered, and becomes free.
Nice idea, except if your Z axis is heavy enough to freewheel to the ground when powered off.
Also, if you mix up the A+, A- and B+ and B- then no current will flow through the windings.
A-A goes to one winding. B-B goes to the other. Very important there are no loose connections, as intermittent connection s will kill most drivers.
If the windings have center taps, leave the center tap floating.
The Syil driver enable inputs are left floating for normal operation. Same for the Mondostep as in the PDF you posted.
