Step 03_Current Settings

Make Note of your Current Settings

Since you will be changing out your CPU and installing new firmware, it is a good precautionary step to make note of your current settings before you begin. This will allow you to reference back to them once the new firmware is installed and help insure you can restore your printer to full functionality.

Note that the following steps assume you are using a Marlin firmware variant that supports the M501 g-code command to retrieve EEPROM settings.

Steps

1. Using whatever program you use to interface with the Printrbot (Octoprint, repetier, pronterface, etc), issue an M501 g-code command
   1. Example, using Octoprint:
      1. Go to Terminal tab:
      2. Type M501, and enter.
         1. Example Output:

 Send: M501
 Recv: echo:Stored settings retrieved
 Recv: echo:Steps per unit:

 Recv: echo:  M205 S0.00 T0.00 B20000 X20.00 Z0.40 E5.00
 Recv: echo:Home offset (mm):
 Recv: echo:  M206 X0.00 Y0.00 Z0.00
 Recv: echo:PID settings:

 Recv: echo:Min position (mm):
 Recv: echo:  M210 X0.00 Y0.00 Z0.00
 Recv: echo:Max position (mm):
 Recv: echo:  M211 X152.40 Y152.40 Z152.40
 Recv: echo:Bed probe offset (mm):
 Recv: echo:  M212 X25.00 Y0.00 Z-0.90 

2. Copy the output and save it in a text file for later.
