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.
- When loading the filament, 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. Tap on the temp tab on the left-hand side of the screen, tap the target box, input the temperature, and then tap the return key at the bottom right-hand corner of the keyboard. Do this for T0 and T1.
If you are going to start a print, at this point, you may want to also preheat the bed. In the same tab, set the target temperature for the bed.
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.
1.1 Load extruder and purge
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.
Start with T0, which is the left-hand side toolhead when looking at the printer from the front. On the top of the extruder body there is a lever and a tab. Push both the lever and the tab in a squeezing motion to disengage the drive gears which will allow filament to be loaded freely. Insert the filament until it reached the tip of the nozzle. Since the hot end is operating at an elevated temperature at this point, some melted filament will leave the nozzle. Then push the lever to release the locking mechanism.
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 100 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.
Go back to the temp tab and tap OFF for the T0 and T1 heaters before continuing to calibration. The bed heater can remain on.
