Example

Setting The Steps Per mm

This is a great way to fix problems you have with you printer not moving the distance you expect, or having your parts come out with incorrect dimensions.

1. Go to 'Advanced Controls'
2. Click on the 'CONFIGURATION' tab File:Eeprom3.png
3. Connect to your printer
4. In the 'EEProm Settings' click on 'CONFIGURE' File:Eeprom4.png
5. Change the 'Steps per mm:' to correct for any discrepancy you find in your movement distances. File:Eeprom5.png

Equation

Here is the equation you can use to find correct values:

Desired_Steps_Per_mm = Actual_Steps_Per_mm * Current_Steps_Per_mm / Desired_Distance

So if your x was set to 80 and you only moved 97mm when trying to move 100mm, you would put in 97 * 80 / 100 And set the X Steps Per mm to 77.6
