Hi All,
I know there was an older topic on this but it was closed.
I’ll try to be short and sweet.
After a little back and forth email with Omtech I have the rotary and z axis both working.
From tech support : " The U axis is the E axis on the board and the A axis in configuration file. " clear as mud right ?!?!
With the follow setting for the config file.
Stepper module pins ( ports, and pin numbers, appending “!” to the number will invert a pin )
alpha_step_pin 2.0 # Pin for alpha stepper step signal
alpha_dir_pin 0.10! # Pin for alpha stepper direction
alpha_en_pin 0.11 # Pin for alpha enable pin
alpha_current 0.4 # X stepper motor current
alpha_max_rate 24000.0 # mm/min
alpha_acceleration 2500 # mm/sec²
beta_step_pin 2.2 # Pin for beta stepper step signal
beta_dir_pin 0.21 # Pin for beta stepper direction
beta_en_pin 0.20 # Pin for beta enable
beta_current 0.6 # Y stepper motor current
beta_max_rate 24000.0 # mm/min
beta_acceleration 2500 # mm/sec²
gamma_step_pin 2.1 # Pin for gamma stepper step signal
gamma_dir_pin 0.19 # Pin for gamma stepper direction
gamma_en_pin 2.8 # Pin for gamma enable
gamma_current 2 # Z stepper motor current
gamma_max_rate 24000.0 # mm/min
gamma_acceleration 1500 # mm/sec²
A axis
delta_step_pin 2.3 # Pin for delta stepper step signal
delta_dir_pin 0.0 # Pin for delta stepper direction
delta_en_pin 2.8 # Pin for delta enable
delta_current 0.6 # Roraty stepper motor current
delta_max_rate 12000 # mm/min
delta_acceleration 1000 # mm/sec²
delta_steps_per_mm 157.575 # may be steps per degree for example
I hope this helps!!
