SmartBOB controllers and dedicated accessories / New installation - morors not reacting
« on: May 29, 2022, 09:26:44 AM »
Hi
I am a definite noob with CNC and have difficulty getting things to work correctly.
I just got my SmartBob424 USB connected to my laptop. Mach4 sees the 424 without errors. The RED and GREEN LEDs light up as expected. DS4 light up when I "enable" the Mach 4 and DS3 fashes when I press the JOG buttons. The stepper motors however do not react.
I have Nema34s connected to DM860A drivers that shipped with them. they are connected as described in their documentation.
The connection from the driver to the SB424 is as follows..
driver side - SB424 side
PUL+(+5v) - COM
PUL-(PUL) - STEP
DIR+(+5) bridged with PUL+(+5v)
DIR-(DIR) - DIR
Two gantry motors are connected to Motor3A and Motor3B - X-axis
Motor2 - Y-axis
Motor3 - Z-axis
I've set the Ste/Dir common to 5v in the PMDX Plugin config screen.
