Required Tools & Equipment
- Wire cutters
Unpack the spool of filament. Slide the filament spool holder rod through the centre hole of the spool, and place it on the spool holder bracket. Make sure to orient the spool such that the filament is fed from the top of the spool, not the bottom.
Unthread the end of the filament from the spool and straighten it out. Cut a 45 degree angle on the end using a pair of wire cutters. The sharp tip helps when feeding the filament through the extruder.
Insert the filament through the filament runout detector and feed the filament until it appears at the other end of the tubing, inside the printer.
Preheat the hot ends to the extrusion temperature for your chosen material using the touchscreen interface. 1. Tap on the temp tab on the left-hand side of the screen. 2. For T0, tap the target box, input the temperature, and then tap the return key at the bottom right-hand corner of the keyboard. 3. Repeat for T1.
Leaving the hot end on for extended periods of time without extruding can burn the plastic inside and cause clogs in the nozzle. Take care to turn the hot end heaters off when the printer is not in active use.
Once the hot ends have reached the target temperature, load the filament into the extruder and through the hot end. If the filament feels stuck and won’t feed through, try pulling it out and straightening it. Make sure the filament has a sharp angle cut on the end. It may take several tries, but this process should require minimal force.
If the filament is forced through the assembly, the PTFE guide tube (between the extruder and the heater block) may become damaged, increasing the difficulty of loading the filament.
If you have difficulty feeding the filament into the top of the extruder, try engaging and dis-engaging the extruder gears while gently pushing the filament in. This can help line up the end of the filament between the drive gears.
If you get the filament through the extruder, but have difficulty feeding it into the PTFE guide tube, try spinning the filament above the extruder to change the angle of approach into the PTFE guide tube. You may also have to re-straighten the filament or re-cut an angle on the end.
Once you have hand-fed the filament down to the nozzle, push the lever to release the locking mechanism and engage the extruder drive gears. You should not be able to manually push or pull the filament through the extruder at this point.
On the touchscreen, navigate to the control tab. Select the Left Tool, set the extrusion distance to 100, and set the extrusion speed to 5.
On the bottom right-hand side of the screen, tap the extrude button twice to feed 200 mm of the filament into the hot end. You should see the filament coming out of the nozzle.
Use the same process for the T1 toolhead, which is the right-hand side, except on the control tab, you should select Right Tool.
Don’t forget to turn the hot end heaters off again if you are not ready to print. Leaving the hot end on for extended periods of time without extruding can burn the plastic inside and cause clogs in the nozzle.
