Con la versione 4.3 CNC ottengo gli stessi risultati della versione 4.9

di seguito cosa riporta il data sheet del driver:
HB860H 2-phase Hybrid Servo Drive
20-70VAC or 30-100VDC, 8.2A Peak
Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each rising or falling
edge active (software configurable, see hybrid servo software operational manual for more detail); In double
pulse mode (software configurable), this input represents clockwise (CW) pulse, active both at high level and
low level. 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. For reliable response, pulse width should be
longer than 10μs. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR
and ENA signal.
Direction Signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of
motor rotation. In double-pulse mode (software configurable), this signal is counter-clock (CCW) pulse,
active both at high level and low level. For reliable motion response, DIR signal should be ahead of PUL
signal by 5μs at least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. Please note that rotation direction is
also related to motor-driver wiring match. Exchanging the connection of two wires for a coil to the driver will
reverse motion direction. The direction signal’s polarity is software configurable.

Ma si può aumentare a 5v l’uscita del master?
bisogna tener presente che la stessa situazione si verificava anche con i DVR8825 montati su cnc shield e motori stepper normali.
dallo schema si evince che sono fotoacc. npn ma non so se sono open collector.
