Page 3: Introduction
1. Introduction Regular maintenance will ensure great performance and a long life for your Fusion3 3D printer. This guide provides a list of different maintenance items to check before every print and to definitely ensure you check each month. If you are ever unsure about completing any of these steps or have additional questions, please contact Fusion3 Technical Support (details found in #15). -
Page 4: Checking Cables For Wear
3. Checking Cables for Wear Fusion3’s drive cables are made of Kevlar. It is unlikely that the cables can break, however, if the cables loosen dramatically, it can cause the cables to fray and eventually snap. Repairing the cables after a breakage is difficult and time intensive. -
Page 5: Ensure Crossbar Is Square
4. Ensure Crossbar Is Square Your Fusion3 3D printer is calibrated at the factory for optimal performance. However, if the printer is jostled or cable tension is reduced dramatically, the XY Gantry can come out of alignment (‘out of square’). It is important that in these instances you adjust the X axis crossbar. - Page 6 To measure the distance from the X crossbar to the front brace, move the crossbar to the rear area of travel and measure as shown below. To adjust left and right idler bolts: You will need a 4mm Allen wrench and a 10mm combination wrench. At the rear of the print volume, the brackets that hold the 2 idler pulleys are mounted on the rear of each Y...

Page 7: Bearing Preloads
Once the pulley is in the desired location, tighten the nut and re-check the square. 5. Bearing Preloads Your print quality and accuracy can also be impacted by undesired movement of the linear motion carriages on the X and Y axis (3 different carriages). -

printing. Using two 13mm combination wrenches or the 3D-printed version, rotate the eccentric cams to adjust the preload. NOTE: It’s possible to over-tighten the cams. Aim for roughly 10 in-lb of resistance when you slide the carriage while holding the wheel still. Repeat this for all 6 pairs of wheels on the linear motion assemblies. -
Page 9: Z Axis Motion
7. Z Axis Motion Overall reliability of your Fusion3 3D printer can be impacted if the Z axis, which controls the raising and lowering of the print bed, is not working correctly. Like the previous step, simply move the Z axis up and down by hand. It’s easiest to home Z, followed by jogging Z high enough to get your hand underneath the substrate and grabbing the belt with your hand. -
Page 10: Ensure The Print Bed Is Level (Manual Leveling)
While getting the bed exactly level is not critical to printing on your F400, you will get best results if the bed is level. On the bottom of the bed plate you will see a small red thumbscrew at each corner of the bed. - Page 11 Run the “Manual Bed Level” macro. At the end of this macro the head will be positioned in the middle of the bed about 10 mm away from it, with the X and Y motors disabled (so you can move the head around by hand). Use the “Move”...
- Page 12 Once the gap gets small use the “-0.05” button to go up in very small increments until you have just a tiny gap between the nozzle and the bed. It can help to shine a light on the wall behind the nozzle like you see in the pictures below.
- Page 13 Now move the head to each corner of the bed (by hand) and use the thumbscrew to adjust the height of the corner until you get the same gap you had at the center of the bed. If you had to make large changes (more than 1 full turn) to any corner, you may want to check all the corners a second time to make fine adjustments.
- Page 14 9. Ensure the Substrate is Level and Check Z Axis Belt Tension The substrate is the platform that the print bed sits on. Print quality and reliability of your 3D printer can be impacted if the substrate is out of level and/or the belt does not sufficient tension.

Page 15: Check The Extruder
10. Check the Extruder The extruder needs consistently and accurately feed filament into the print head. Check the extruder for: ● Debris in the feed gear ● Slop or lash in the gears ● Correct spring preload Feed Gear Debris Service interval: every time you change filament spools or if you experience a printhead jam. -
Page 16: Gear Lash
Gear Lash Service interval: As needed (check with extruder empty of filament) While spinning the extruder by hand, check for lash in the gears by gently reversing the direction you’re turning the extruder. Observe the gears and make sure there isn’t a “dead spot”... -
Page 17: Spring Preload
Slide the motor up until the gears mesh firmly. Gently snug the bolts to where the motor will still move when forced. Spin the gears at least 2 full rotations by hand and make sure they spin freely with no binding. If there are tight spots, rotating the gears should allow them to self-adjust. -
Page 18: Wipe Down The Printer
If you need to adjust the springs, use the 2.5mm hex wrench from your toolkit. 11. Wipe Down the Printer A clean printer is a happy printer! Use a moist paper towel to wipe down the interior and exterior of the printer. Be sure to wipe the windows only with water, using gentle, single- direction swipes. -
Page 19: Wipe Nozzle
If you see dark, burnt-looking plastic that has appeared on top of the heater block, this is a sign the print head may be leaking. Please contact Fusion3 Technical Support if you see this. Note: It’s normal for the surface of the print head to become dark and coated with carbon after a while. -
Page 20: Check Heat Break Tightness
14. Check Heat Break For long-term performance and reliability of your print head, you need to check the assembly and tension of the print head. Make sure the hot section of the print head is still firmly threaded into the cold section. Service interval: When the print head is cleaned WITH THE PRINT HEAD COLD, grasp the heater block with your fingers and gently twist it... -
