PLEASE READ CAREFULLY BEFORE PRINTER OPERATION
EVO is an advanced machine capable of reaching extremely high temperatures and fast speeds.
Please be aware of possible hazards when operating.
The heated bed can reach temperatures of 160C and also generates heat inside the enclosed chamber. The hot end reaches temperatures of 315C. Never touch the heatbed or hot end while hot, and keep in mind they may take up to 20 minutes to fully cool down.
Recently extruded plastic can stick to the skin and cause burns if not careful. Always wait until the hotend is completely cool before removing unwanted plastic or debris. The stepper motors can also generate high temperature and contact with the skin should be avoided.
Flammable materials or liquids should never be placed or stored next to the printer.
ELECTRIC SHOCK HAZARD
The internal electronic components can cause electric shock even when the printer is powered down or unplugged. Never remove the back panel without consulting your Airwolf 3D technician first. ALWAYS disconnect ALL power to the printer before performing any repairs.
MOVING PARTS HAZARD
Never touch moving parts or place your fingers in or on any of the belts, pulleys or gears while the printer is operational. Make sure to tie back hair and remove any dangling jewelry.

Tips & Tricks
Small parts finish quicker and require fewer settings adjustments.
EVO is designed to print ABS continuously and it will give the best results.
This ensures the best surface finish and longest life of product. It also reduces any chance that the glass will chip or break.
- Use high quality filament
- Filament greater than 3mm may cause hot end to jam
- Dry filament tends to print more consistently than filament subjected to moisture
- Apply fresh Wolfbite Mega on cool, clean glass
- Set nozzle to 290°C+
- Set bed to 150°C
- Set chamber to 60°C
- Use large (.25mm+) layer heights
- Keep infill speeds slow — fast speeds can cause skipping
- Open the top of the machine, if possible.
- Turn off chamber heaters.
Prior to loading filament, prime hot end with PLA. PLA will flush out existing filament and melt quickly when TPE or TPU is introduced.
Slow down print speed to 16mm/s or less and increase retraction amount to 5mm or more.
Prior to loading filament, prime hot end with PLA. PLA will flush out existing filament and melt quickly when HydroFill is introduced.
Use a prime tower when possible to keep HydroFill flowing and primed between layers.
Only for advanced users. For instructions on nozzle offset calibration, see section on Precise Dual Color and HydroFill.
Nozzle offset calibration is necessary for optimal dual nozzle printing.
1. Print out a sample dual material piece with walls abutting each other in both X and Y directions.
2. Measure second nozzle overlap in both X and Y directions, and save these values.
3. In APEX Software, navigate to Expert > Switch to full settings.
4. Once in the Full Settings interface, select Machine > Machine settings.
5. Under Extruder 2 settings, enter recorded X and Y overlaps.
6. Reprint test piece and perform again until walls cleanly adjoin one other
1. Lower print temp
2. Lower bed temp
3. Turn off chamber heater
4. Increase fan speed
- Increase bed temp to 145°C
- Set chamber heater to 60°C
- Apply wolfbite over entire surface
Increase chamber temp to 60°C
The most efficient and reliable way to print large parts is with either a .8 or 1.0mm nozzle. Larger nozzles create less back pressure and are more resistant to jamming.
Part definition with large nozzles will still be high, especially when using “Fine” or “Precise” settings in APEX. Print time with large nozzles can frequently decrease by 50% or more. Additionally, because wall thickness will be increase, parts tend to be stronger.
To level nozzles, perform the following steps:
1. Loosen right bolt and tilt until hot ends are approximately level.
2. Tighten both bolts.
3. For more precise leveling, use the Bed Bob function to enable print bed to be used as a visual guide for leveling nozzles.
To Use Bed Bob
1. Press the CONTROL tab and click the “gear” button.
The machine will autohome, heat and clean nozzles on brush, auto-level, and move the hot end to Home position. The machine will then automatically enter SERVICE MODE, bringing the hot end to center position for easier access.
A new window will open.
2. Click the Bed Bob button to raise the bed.
3. Once the bed is in a fully raised position, make minor adjustments as necessary until nozzles are visually level.
NOTE: The Bed Bob function simply toggles the bed into a raised or lowered position.
4. Once nozzle leveling is complete, click the CLOSE button and the machine will automatically auto-home.
Replacements – Designed exclusively for the EVO, Nozzles are available in 1.0 mm, .80mm, .50mm or .35mm sizes. (SKU: A25203)
IMPORTANT: Only change one nozzle at a time. If both nozzles are loosened, entire hot end assembly will become loose.
1. Heat nozzle to temperature of inserted filament
2. Select filament change and remove filament from nozzle to be changed
3. Power down machine (head should be in service position and bed should be at lowest height)
4. Wait for nozzle to cool
5. Use an M2.5 hex wrench and loosen each of the three 50mm screws holding the nozzle to the heater body
6. Place one bolt inside the replacement nozzle and lightly screw in to hot end assembly
7. Repeat for the second and third bolts
8. Tighten all bolts evenly, and power machine back on to test
1. Heat primary nozzle to temperature of inserted filament
2. Heat secondary nozzle to temperature of inserted filament
3. Select filament change and remove filament from both nozzles
4. Power down machine (head should be in service position and bed should be at lowest height)
5. Wait for nozzles to cool
6. Use an M2.5 wrench to remove both 55mm screws in the fan cover (the two additional holes are for modular hot end removal and adjustment)
7. Carefully pull the fan off and separate the 4-pin connector
1. See steps 1-7 of Fan Housing Removal/Replacement
2. If filament is still jammed between feeder and hot end assembly, use a razor blade to cut filament in the space between the two
3. Use an M2.5 wrench to remove all four bolts coupling the feeder to the modular hot end assembly
4. Pull the feeder off, and inspect and clean as necessary
CAUTION: Do not plug or unplug wires while machine is powered on.
1. Remove filament from both nozzles (if necessary, cut filament as shown)
2. Put machine into SERVICE mode
On touchscreen home display, click SERVICE MODE.
3. Power down machine
CAUTION: Machine must be powered down to prevent damage to GENESIS board.
4. Wait until hot ends are cool
5. Carefully remove left and right plugs from harness mount by grabbing plugs, not wires (plugs will be tight)
6. Insert M3 allen wrench into left recess in fan cover and loosen
7. Repeat for right recess
8. After both bolts are completely loosened, remove extruder assembly
9. Repeat in reverse order to install new extruder assembly
10. Level extruder assembly
Before resuming operation of the machine, follow the instructions in Section 7.1 Leveling Nozzles.
Every 100 print-hours, clean bed rails for accurate auto-leveling.
1. Auto home and power down machine
2. Use razor blade to scrape film off steel bed rails for precise contact between rails and hot end
Every 100 hour print hours, clean nozzles for accurate auto-leveling
1. Press SERVICE MODE.
2. Power down machine.
3. Carefully take wire brush to body of nozzle and remove residue
The glass used for the EVO build plate is high-temperature, borosilicate glass. Like filament, the build plate is a consumable. It will degrade over time.
To prolong the life of the build plate, practice the following:
- Only apply Wolfbite to a cold plate
- After a print, be patient and let the surface slowly cool down until the part releases
- Make sure the nozzle is not pressing the first layer into the glass — too close of a first layer will create a very strong bond that can damage the build plate
Every 1000 hours of print time, replace both HEPA and carbon filters.
1. With the build plate clear, select CONTROL
2. Use the pointer to push the Z-axis to the top of its travel
3. Power down machine
4. Unscrew the filter cover and both filters should easily drop out
5. If necessary, use a small screwdriver to gently pry out the filters
6. Replace in reverse order
Replace brass brush every 1000 hours, or sooner, depending on condition.
1. Place machine in SERVICE MODE
2. Use 2.5mm hex wrench to unscrew both screws holding brush to bed plate
3. Lift out brush
4. Reinstall in reverse order
Every 1000 hours, lubricate Z stage ballscrew. White lithium grease is recommended. Any grease used should be rated for more than 80°C continuous.
Please see Section 8.3 Update Touchscreen.
Please see Section 4.11 Update Firmware.
After running out of filament, it is not possible to remove remaining filament in feeders.
Insert new filament into feeder opening, press FILAMENT CONTROL and then press PRIME.
PRIME slowly feeds new filament into feeder. Do NOT press LOAD as it will force new filament in too fast and potentially jam.
Auto-leveling errors are most likely the result of a poor connection between the nozzle and the bed.
Make sure that the M3 screw holding the orange sensor wire to the underside of the heater body is tight.
For best results, clean both nozzles and bed rails as described in Maintenance section.
1. Use correct Wolfbite (apply while glass is cold).
2. Increase temperature on bed.
3. Center print on bed for even heat distribution.
4. Ensure first-layer nozzle distance is correct.
Change to smaller-letter firmware, if necessary, to press first layer down.
5. If bed is cooler toward back, update to latest HEPA Fan Duct Design.
Download: Fan Duct V2 Rev A STL
Too close (filament jamming into glass)
1. Make sure nozzle and bed rails are auto-leveling correctly (nozzle will quickly retract once rail is contacted — if not, refer to maintenance section to clean nozzle and rails.
2. Select SETTINGS and then UPLOAD FIRMWARE
3. Select a higher letter (“A” — closest to bed, “E” — farthest from bed)
Too far (filament barely grazing print surface)
1. Make sure nozzle is contacting bed rails during auto-leveling. If no contact, the Modular Hot End is grounding prior to auto-leveling.
2. Select SETTINGS and then UPLOAD FIRMWARE. Select a lower letter (A-closest to bed, E-farthest from bed)
1. Heat nozzle to 20 degrees OVER recommended filament temperature (e.g. ABS to 260°C)
2. Select FILAMENT CONTROL
3. Press PRIME, and firmly press down on the filament to slowly push filament through the hot end. Repeat until filament exits tip of hot end.
If filament will not extrude, press REMOVE
If the above process does not remove the filament, use the following procedure:
1. Place machine in SERVICE MODE
2. Turn machine OFF
3. Remove two (2) M3 screws that hold front cover:
4. Remove front cover (not necessary to remove fan connection):
5. Remove four (4) M3 screws that hold feeder assembly
6. Use razor blade to cut filament between feeder assembly and hot end mount
7. Remove feeder assembly and remove filament
8. Reassemble in reverse order
Only one type of malfunction can produce Y-axis layer shifting in the EVO Additive Manufacturing Center: the shifting of the glass plate.
To make sure that the glass plate is properly positioned, the corner screws must not be fully tightened.
The corner screw and attached nut should be able to move around (yellow arrows) as the full upward force of the spring (red arrow) clamps the underside of the glass.
If HydroFill or nylon is exposed to humidity, printing performance can degrade quickly. However, EVO’s heated chamber will eventually dry the filament.
For best results, use a .8mm secondary nozzle for extruding HydroFill. This will reduce back-pressure and support reliable filament delivery.
Prior to printing with HydroFill, make sure to prime the second nozzle. Once material is flowing, EVO is ready to print.
Every 20-40 hours of dual extrusion HydroFill printing, prime HydroFill through with PLA. This should be done at 240C. Remove HydroFill and load PLA. Once loaded, prime PLA until all HydroFill remnants are purged.
Future versions of APEX 3D-Printing Software will account for the unique first-layer bonding characteristics of HydroFill.
For current versions of APEX, navigate to Expert > Switch to Full Settings. Select the Advanced tab.
Under Quality > Initial layer line width (%), change the value from 100(%) to 120(%). This will provide slight over-extrusion on the part’s first layer.
