How Is The Order Of Signals Sending Out To The Printerports?
Answer»
First the direction signal SEND out, e.g. if X-forward and spindle enabled [BINARY 64].
At second the direction signal INCLUSIVE the clock signal send out [binary 65].
A step is executing with pos. edge of clock! Code in C: outp(0x378,64); outp(0x378,65);
The databits 1,3,5 are the direction bits. If forward set on [0], if backwards set on [1].
The signal of current boost should be connected to the clock signal in parallel.
MAKE sure that the primary current (30% to 70% of boost) is enabled on the driver-unit to hold the motor in constant position while don't have motions.
