AWC 608
Main Board 8.12.01.28
LCD Board 5.12.01.05
LaserCAD v5.85
I come to laser from the CNC world. In step and direction motion control, steps are referred to as "steps per unit" (step per inch or steps per mm)
On the AWC608 it seems to be otherwise. "Pulse unit" is how it is shown on the manufacturers parameters settings. However it is in reality not steps per unit. It is some other thing.
My X and Y axis are designed and built to be 1000 steps per inch (39.37 steps per mm). But entering 39.37 in "Pulse Unit" leaves it way out, in distance travelled.
In fact I must enter something like 25, to make it travel the commanded distance.
So what is "Pulse unit" ? I have even heard it referred to as "pulse width". Very confusing terminology, normally refers to PWM.
The first thing others will say is, you have your calculations wrong. That's what I would say.
The calculations are not wrong.
I have been running this laser up till now with Mach3, which I am very familiar with, at 39.37 steps per mm.
So can someone set me straight. What is "Pulse Unit"?
