Unclogging the 3D45 Extruder

This video will walk you through the steps to properly clear out a clogged extruder.  Since the reason the extruder may be clogged is not yet clear, the video will provide a several options to help you clear out the clog.  You can also download the PDF instructions here.

Replacing Runout Sensor on the 3D45

If your printer isn't able to detect when the filament has runout, you may need to replace the filament run-out sensor on your printer. To do this, the top cover of the extruder will need to be replaced. To do this, follow the steps outlined in the PDF instructions here.

Nozzle Gap Calibration

This video will walk you through the steps to modify your gap offsets and therefore achieve better print results. You can also download the PDF instructions here.

Having the correct nozzle gap is vital to achieving successful prints. The nozzle gap, also referred to as Z-Gap, is the distance of the nozzle to the build platform when the first layer is being printed. It is important to ensure that the first layer sticks well to the build platform, therefore, the nozzle gap needs to be ideal. Too large of a nozzle gap may lead to a not well adhered first layer, leading to object shifting, and a too small nozzle gap may lead to a non-visible first layer, possibly leading to clogging issues.
