The electronics board on top of your extruder is called the "Uptown board" and the one below your extruder is called the "Downtown board". Using this guide, make sure all cables are properly plugged into the right place. |
|
Make sure the extruder power is all the way into its socket on the Mainboard. Use the R2 Wiring Diagram to locate the terminal and double check the connection. |

'Filament not extruding'
Tips & Links
|
Description

|
If your Z-Offset is set too low, filament will not be able to escape the nozzle. Use this guide to properly set it on your R2. |
|
The gear in the extruder can build up residue over time. When this happens, the gear is unable to properly grip the filament and drive it through. Follow this guide to clean your feeder gear. |
|
Filament sometimes gets jammed or solidifies inside the extruder preventing new filament from being driven through. Follow this guide to help you unclog your extruder. |
Check your slicing settings
|
There are various slicing programs. Whichever one you use, make sure you're correctly setting the extruder temperature and bed to the temperatures recommended for your filament. |
|
Your extruder may not be holding temperature as intended. Every extruder performs a little differently. PID Tuning will help you dial in your settings unique to your extruder. These settings will help stabilize the temperature of your extruder, and aid in preventing future clogs. |
'Prints not sticking or Air Printing'
Tips & Links
|
Description
|
|
If your Z-Offset is set too high, you'll have bed adhesion problems. If your Z-Offset is too low, filament won't be able to escape the nozzle. |
Bed Calibration (Wizard)
|
On the touchscreen, there is a Bed Calibration Wizard under Utilities. This wizard will help you adjust your thumbscrews to create a more level bed. |
|
The FTZO Wizard will help you visually see the Z-Offset. You can increase or decrease the Z-Offset in small increments and then print a line to test it. Always make sure you run the Z-Offset Wizard before the FTZO Wizard. |
Check your slicing settings
|
There are various slicing programs. Whichever one you use, make sure you're correctly setting both the extruder and bed to the recommended temperatures for your filament. Also make sure your fans are not turning on during the first few layers to encourage adhesion. |
