Hello again,
I have tried to calculate my self "steps per" magical number, but i don't understand few things. I read this topic "Understanding & Selecting gear pinions" and downloaded excel calculator.
I have Wantai stepper driver, on driver i can choose "Pulse/rev" to: 400,800,1600,3200...... 1000,2000,5000.... And my stepper motor is "1.8 step angle=200 full steps for one revolution"
So calculating "Driver Microsteps" in excel calculator i have:
1/2=400 is equals to 2 "driver microsteps"
1/4=800 is equals to 4 "driver microsteps"
1/8=1600 is equals to 8 "driver microsteps"
1/10=2000 is equals to 10 "driver microsteps"
I am right ?
If yes lets go next:
I have rack&pinion system with Module 1.5 and 12 tooth pinions. Reduction is belt driven 3:1.
In excel i got Steps per (millimeter) with "Driver microsteps" set to 10 : 106.103 <- this is magical number witch i have to enter in Mach3 "Steps per" window ?
If i am right what "Driver microsteps" i have to choose for my machine (3x2m working area) ? I read somewhere that setting 1/16=3200 pulse/rev is good ?
My motors are Nema34, 1600oz
