2. 4th axis pulse equivalent SETUP:
Mach3 system settings
|
number of pulses of 1 Degree |
(number of pulses of Motor/lap* micro-stepping levels of Drive * reduction ratio)/360 degree |
|
such as: Two phase Nema23 Motor micro-stepping levels:16 reduction ratio:50 |
(200×16×50)÷360=444.44444444
|
control card system settings
|
The angle of one-pulse
|
360 degree/( number of pulses of Motor/lap* micro-stepping levels of Drive * reduction ratio)
|
|
such as: Two phase Nema23 Motor micro-stepping levels:16 reduction ratio:50 |
360÷(200×16×50)=0.00225
|
The replace algorithm of X or Y Axis :
perimeter/( number of pulses of Motor/lap* micro-stepping levels of Drive * reduction ratio)
