Section 5.1 Testing Functionality

You have almost finished building your printer. Now we will test if all the connections are correct.

Testing Temperature

• Turn on the printer. Check if the fans on the side of the hotends are working.

• In the display menu push the button once and navigate to: >Prepare >Preheat PLA >Preheat PLA All or if you have a single extruder >Preheat PLA 1

• Wait until the menu jumps back to the info screen and check if the temperatures of the nozzles and the heatbed are rising.

  • You don’t have to wait until the temperature reaches it’s goal value.

• In the mean time navigate to: >Control >Temperature >Fan Speed and turn it up to 255 and confirm with a push on the button. The active fan on the back of the extruder should turn on now.

• Load some filament by navigating to >Utilities >Load Extruder0

  • The left extruder will heat up automatically now, once it’s hot the filament pulley will start turning.

  • Put in some filament until some is extruded.

  • Push the button to stop.

  • If the filament pulley turns the wrong direction turn around the connector on the RUMBA board.

• Do the same for the right extruder with >Utilities >Load Ext. 1

Testing Motion

• Turn on the printer. In the display menu navigate to: >Prepare >Move Axis >Move 10 mm >Move X and turn the knob some steps in clockwise direction. The printhead should now move to the right.

  • If the printhead moves to the left you should turn the connector by 180° on the RUMBA.

• Do the same for the Y-Axis. The print platform should move to the front.

• The same for the Z-Axis. Choose >Move 1mm instead of >Move 10mm in the Move Axis menu. The X-Bridge should move up.

  • Note the printer will refuse to move in a negative direction as long as it hasn’t detected the endstops.

• Test the endstops again by manually moving the axis to it.

  • To move the axis by hand navigate to >Prepare >Disable Steppers. This will set the motors free.

• If you are sure that all the endstops work navigate to >Prepare >Auto Home the printer will now home all axes.

  • Keep your finger at the power switch when you do this for the first time. If the Z-Axis fails to detect the endstop the motors can potentially destroy some parts of the printer.

• If everything worked correctly your printer works. Next install the missing parts from the electronics case.
