Spindle setting on lathe machine
« on: September 12, 2022, 07:16:39 AM »
My system looks like this:

Controller: Smooth Stepper

BOB board: CNC4PC

Spindle motor: AC servo spindle (Panasonic)

Spindle control method: Step and Dir control method (step motor control method)

Problem: Working with Threads





My spindle amplifier outputs 2500 pulses per revolution.

Input 2500 to Encoder Prescaler and 3 to Effective PPR to use.

(Smooth stepper spindle setting)

With this setting, the actual RPM will appear exactly on the screen of Mach 4.
( True Rpm )

Create a new job in machMotion Threding Cycle and enter basic values

Xi = 20 , Zi =0

Zf =-20

With this setup and start up, the spindle RPM's are almost low, and they don't appear to move at all.

(It's running, something is moving very slowly, but it doesn't seem to work at all)

What am I missing?

Normal machining is working without problems.
Threading is a problem
