General Mach Discussion / Understanding steps per and config
« on: February 10, 2010, 08:27:05 PM »
Hi,
I recently purchased a new K2 CNC Mill (KT1414) frame only, I already had the electronics for it. When I received my mill I also received a cd with settings for Mach3 (*.xml) that I just dropped into the Mach3 directory.
After going through this config and making sure the pins were set correctly, when I tried to move any of the steppers they would start to move VERY quickly and then stall. I contacted K2 to try and see what I was doing wrong and they really didn't have much to offer other then verifying the motor tuning settings. This is what they have for settings:
Steps Per = 20000
Velocity = 100.62
Acceleration = 30
Step Pulse = 5
Dir Pulse = 0
They also have kernel speed set to 35000Hz
The setup for electronics that I have are:
1 KL-DB25 Breakout Board
3 KL-4030 Micro stepping Drivers set to 1/8 micro stepping
3 LK23H2100-30-4BM 495 Oz inch steppers
1 KL-320-36 36v/9.6amp power supply
The Mill lead screws are all .1 pitch (1/2" 10 tpi)
I have calculated that the steps per should be 16000, I am trying to figure out where they have 20000 for Steps Per, standard steppers 1.8 degree 200 steps per rev.
I am hoping someone could help me understand this
Thank You
