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.

BURN HAZARD

The heated bed can reach temperatures of 160C and also generates heat inside the enclosed chamber. The hot end can reach 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.

FIRE HAZARD

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.

OTHER SAFETY CONCERNS

WHILE PRINTING, DO NOT LEAVE MACHINE UNATTENDED!!!

If you must leave the printer, make sure to hook up an external video camera for video monitoring.

Age: If under 18, do not operate the machine without adult supervision.

Choking Hazard: The machine features small parts which can be a choking hazard for young children.

• While it may be tempting to go online and find the cheapest filament, believing all to be the same, this is a BIG mistake.  Cheap imported filament will affect not only the quality of your prints, but also the lifespan of your machine.
• If you need a specific color that we do not sell, you can always request a particular color.  All of our filament is made from 100% pure plastic pellets.  We do not “cut” our filament with additives to reduce cost.
• Cheap filament contains unknown fillers that can cause jams and ruin your hot end.  Melt temperatures may be inconsistent and these filaments frequently leave residue in your hot end, making your machine inoperable.
• Here is an example of hot end teflon tubes that have been rendered inoperable because of low-quality filament:

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

• Keep top on and door closed
• Use either Wolfbite Original or Wolfbite Mega
• Small prints require less heat on bed and in chamber
• Chamber will rise to 50°C, even without chamber heaters
• Fan speed over 40% may cause hot end temp to drop and jam hot end

1. Apply fresh Wolfbite Mega on cool, clean glass
2. Set nozzle to 290°C+
3. Set bed to 150°C
4. Set chamber to 60°C
5. Use large (.25mm+) layer heights
6. Keep infill speeds slow – fast speeds can cause skipping

Warning: PLA will eventually degrade and lose its material properties when left inside the EVO’s heat-retaining chamber.  In particular, PLA can crack and splinter in the 5/16″ Teflon feeding tubes and become difficult to remove.  Please use the following procedure when printing with PLA:

1. Remove the top glass (to avoid trapping heat in the chamber)
2. Nozzle temp should not exceed 240C
3. Heated bed temp should not exceed 70C.
4. Chamber heaters must be off.
5. If possible, feed PLA from the top of the machine into the feeding system (to avoid passing through the Teflon feeding tubes).

1. Replace your standard V.5 (or later) feeder with the “FLEX” feeder made available from 12/2019.  The FLEX feeder produces a stronger bite on the filament for better extrusion of softer materials.
2. Update to firmware version 1.58.9 (or later) which more precisely controls side fan speed and hot end temperature.
3. Update to Apex version 1.7.1 or later.
4. Prior to loading filament, prime hot end with PLA. PLA will flush out existing filament and melt quickly when TPE or TPU is introduced.
5. Slow down print speed to 16mm/s or less and increase retraction amount to 5mm or more.

• New users should use a .8 or 1.0 mm nozzle when printing HydroFill Water-Soluble Support. The larger nozzle reduces back pressure and reduces the chance of jamming, especially with chamber heaters activated.  With that said, the updated G-series hot end incorporates Teflon feeders which greatly reduces the chance of jamming.
• Prior to loading filament, prime hot end with PLA. PLA will flush out the 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

1. Increase bed temp to 145°C
2. Set chamber heater to 60°C
3. 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.
• Strength – because wall thickness will be increased, parts tend to be stronger.
• Check out Airwolf 3D’s guide to printing large ABS parts.

To level nozzles, perform the following steps:

1. Insert 3mm hex into right opening in fan cover and loosen bolt.

2. Tilt until hot ends are approximately level.

3. Tighten both bolts.

4. Start a print and check the relation of both nozzles. if necessary, loosen the right bolt, relevel and retighten.

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 9.1 Update Touchscreen.

Please see Section 4.11 Update Firmware.

EVOs can restore almost any type of print failure. To recover your print, follow these steps (if printed from USB drive, make sure drive is in printer):

POWERED DOWN MID-PRINT

Power outage or a user accidentally powers down the printer.

1. Power up printer.
2. Press RESTORE LAST icon.
   • Printer will reheat and start where it left off.
   • Bed temp will slightly overshoot to re-adhere part if printer has cooled.

(Alternative)

1. Power up printer.
2. Press PRINT
3. Select prior print file.
   • Prompted to “restart print where you left off”.
   • Confirm and printer will reheat and start print where it left off.
   • Bed temp will slightly overshoot to re-adhere part if printer has cooled.

STOPPED MID PRINT

User accidentally stops printer mid-print

1. After running out of filament, it is not possible to remove remaining filament in feeders.
2. Insert new filament into feeder opening, press FILAMENT CONTROL and then press PRIME.
3. PRIME slowly feeds new filament into feeder. Do NOT press LOAD as it will force new filament in too fast and potentially jam.

• EVO calculates values for auto-leveling by probing 4 corners of the print bed.
• Z values are recorded when the aluminum nozzle makes electrical contact with the stainless steel bed.
• Auto-leveling errors are most likely the result of a poor connection between the nozzle and the bed such as when material is blocking the two from touching.
• Make sure that the M3 screws holding the orange sensor wire to the underside of the heater body are tight.
• For best results, clean both nozzles and bed rails as described in the Maintenance section.

1. Use correct Wolfbite (apply while glass is cold).

ABS/PETG/TPU/TPE – Wolfbite Original
PLA – Wolfbite Nano (works best at 60-80°C)
ABS/PC – Wolfbite Mega
Nylon – Wolfbite Nitro
Polypropylene – Wolfbite Ultra

2. Increase temperature on bed.

PC: 155-160°C
ABS: 145-150°C
PLA: 70-80°C

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.

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

• Generally, 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.
• For nylon, it may help to replace your standard V.5 (or later) feeder with the “FLEX” feeder made available from 12/2019.  The FLEX feeder produces a stronger bite on the filament for better extrusion of softer materials.

Update to the most current version of APEX to account for the unique first-layer bonding characteristics of HydroFill.

• If the side fans cool off the hot end during printing, upgrade your EVO to firmware 1.58.8  (or later).
• When necessary, such as in the lower portions of the print, or when running the side fans over a large flat area, this firmware modulates the side fans in response to hot end temperature fluctuations.

• If bed lowers during auto-leveling such that nozzle pulls out of the brush, upgrade to firmware 1.58.8 or later. 
• Earlier versions of the firmware may sense an errant ground connection between then nozzle and the brush when the EVO is performing its nozzle cleaning routine.  When this happens, the bed may lower and detrimentally affect the auto-leveling calculation. 
• Upgrading firmware will limit ground sensing to situations only involving auto-leveling.
  

• Firmware versions 1.58.8 and later implement a more sophisticated stepper control algorithm promoting quieter (and smoother) operation. 
• Upgrading firmware will substantially improve printer performance.

Update the Touchscreen on your EVO by performing the following steps:

1. Make sure EVO is connected to the internet
2. Select SETTINGS
3. Select CHECK FOR UPDATES (if this does not appear, select back)
4. Select OK to update Touchscreen

DO NOT TURN THE PRINTER OFF DURING UPDATE.  THE PROCESS MAY TAKE SEVERAL MINUTES.

NOTE: Once the Touchscreen is up to date, the latest firmware for the GENESIS microcontroller will become available in the Touchscreen’s internal drive.

On TouchScreen versions 1.61 and higher, Genesis firmware will automatically update when the TouchScreen is updated.  Genesis firmware can also be manually updated as follows:

1. Select SETTINGS

2. Select UPDATE FIRMWARE

3. Select INTERNAL (or USB if updating via thumb drive)

On TouchScreen versions 1.64 and higher, there is only one firmware for each printer type.  Z offset values can be changed by pressing the firmware version on the top right of the screen (e.g, 158.16.C).  A special menu will appear and allow you to adjust the offset. “A” will set the first print layer closest to the bed and “G” will set it farthest from the bed.

DO NOT TURN THE PRINTER OFF DURING UPDATE.  THE PROCESS MAY TAKE SEVERAL MINUTES.

ScreenLock protects your work by locking the Touchscreen and preventing others from changing settings on the machine.

NOTE: ScreenLock feature is only available in Touchscreen Version 1.48 and later. If you do not have Version 1.48 installed, follow the instructions in Section 9.1 Update Touchscreen to update your machine and automatically enable ScreenLock. Once your Touchscreen is updated, a “lock” icon will appear in the upper right corner of the Touchscreen display.

To enable ScreenLock on your machine, press the “lock” icon. Your Touchscreen and machine settings are now locked.

To disable ScreenLock and re-enable Touchscreen settings, press the “lock” icon and enter your passcode.

The default passcode is: 0000. Learn to change your passcode in Section 9.4 Change/Reset ScreenLock Passcode.

By default, your Touchscreen passcode is 0000. To change your password, navigate to SETTINGS > DIAGNOSTICS > CHANGE PASSWORD.

Passcodes must be 4-10 numerical characters.

If you lose your ScreenLock passcode, please contact the EVO Customer Service Team for a temporary master reset code.
