Tools
Besides the included toolkit, you will need
- Scissors
- 5.5mm wrench
- Grease Syringe
- Blue loctite
Read through this manual once before starting.
Gather tools and clear a space for assembly.
Remove two stop blocks from aluminum extrusions (some early shipments did not
include this.) Using a 3mm hex key, remove the frame bolts. If screws do not
have threadlocker already, apply blue loctite to the first 4 threads. Then,
reinstall with the suggested gap of 2 ½ turns.
Turn the screw out 2.5mm about 2 ½ turns. Install the Z axis extrusions making
sure the ball is facing up. Be sure the extrusions are flush against the
sheetmetal beneath the print bed. Tighten all of the screws (all 4 corners)
until the extrusions are held in place (just past loose) then, fully tighten
each screw. Repeat, tightening all four Z axis extrusions in place. Mount the
feet to the bottom of the printer. They are adjustable so you can level the
machine in its final location. Put foam on print plate from the box. Pictured
with top frame attached, but we suggest installing the gantry before the top
frame to make it easier First, inspect the printhead to make sure no cables
are hanging below the nozzle
Tilt the gantry into the machine (again, easier with the top off) Place the
gantry on foam. Mount the Z Axis idler pulleys loosely (4 total, 1 in each
corner – pre-assemble off the printer on a flat surface) Screw the bolts in
just enough to hold the brackets, the bolt should be flush with the hole in
the bracket. All 4 mounted shown below Mount the top sheet metal plate.
Install Z axis belt to the hook below (buckles are pre-installed on LF.RF,LR)
Use the following as reference Pass the other end of belt through the holes in
the sheet metal. Pass belt through the top idle pulley. Slip a buckle onto the
belt. Fold the belt as shown. Ensure the cabling at the back right corner
passes behind the belt. Back Right is shown below. Slip the buckle onto belt
over folded flap and tighten it with a M3 set screw. Install the belt to the
hook below. Pre-tension the belts (will set tension later) with the screws on
the top. Note: viewing from the side bottom, the belt needs to be in the
tooth groove of pulley. Turn the four 80T pulleys by hand from the side to
raise the gantry to a certain height.
Use the included ruler and adjust 4 corners within 1mm. Remove the foam. Plug
the cables of drag chain into below socket according to label aside. Fix the
sheet metal for Z axis drag chain using a M2 ball end hex. Rotate 80T pulleys
to make four corners of gantry be in same height.
(Note: the height error between four corners should not exceed 1mm,
please measure height by ruler and recheck the height error repeatedly) Rotate
the screw holes of four movable hinges to the center. Insert M5 screw and
spring washer, the screw should be aligned with the threaded hole of movable
hinge. Rotate the screw a little to prevent the movable hinge from falling
off, but don’t tighten the screw completely in this step. Install all four
movable hinges in the same way. If it’s difficult to align the screws with the
threaded holes on movable hinges, please loosen four M4 screws at the back of
gantry for adjustment. Tighten back these M4 screws until all four holes are
aligned. Now it is time to tighten the Z axis belts. Adjust the belts to 140Hz
as described below. More info at Voron / Belt Tension (link) Apps
iOS: Sound Spectrum Analysis
Android: Spectroid
Both: Gates Carbon Drive (use the “motorcycle” option)
This app shows a single frequency rather than a graph. It’s more difficult to
get a good reading, but easier to interpret the result. A good starting point
is 140hz. You will follow a similar process.
- Move the gantry upwards until the fixed side of the belt is 150mm from the Z idler centers.
- Pluck, measure, and adjust, same as above.
- Move your gantry down at least a few centimeters and then back up again. Re-check your tensions.
While tightening the belts, check they sit correctly in the upper and lower
pulleys.
This is also the time to check the A/B belt tensions as described in the Voron
link above. A number of users have reported that the belts on their machines
had a much higher tension than recommended. If the machine came from TM3D with
a Full Service Package, this will already have been checked.
Tighten the 4 thumb screws to secure the movable hinges. From the top, this is
CCW Tighten the four M5 screws in a cross pattern with hex wrench. Loosen the
thumb screws to release the movable hinges If the movable hinges are not
released, the leveling effect of the gantry will be affected. Apply 1mm thick
foam tape onto the inner side of the black rear panel as shown leave the
outside protective film on.
NOTE: If double sided tape is included (early versions) to leave film on.
If foam is sent, disregard Glue VHB tape to the air filter as shown. Put the
activated carbon cotton into the air filter. Attach air filter to the outside
of the black real panel. Install the screws first, holding the area with the
VHB tape away from the panel, then press the VHB to the back panel. This will
help in positioning the air filter. Plug the cables for air filter, LED light
and filament run-out sensor. Use the yellow label on the base for reference
Place the rear panel on the bottom frame – it will slot into the skirt –
watching for camera and led cables shown in next step Pass cables through the
bottom slot of Rear panel. Close the rear panel and pass the LED (and webcam
if installed) cables through the top slot. Mount the rear panel with 9 x M3
*10 BHCS screws. Use 3 cable ties to attach the cable bundle to the positions
shown below. Put the cables running from the bottom up into the sheath and fix
the buckles. Install the screw bracket for PTFE tube support. Review TM3D
guide for Filament Sensor update Move the extruder to the front left corner
and install the PTFE tube.
(Note: please reserve enough length of PTFE tube inside chamber, or else,
the extruder will be pulled up during print) Put a M5 T-nut in below position.
Install the filament spool holder. Install the front door as shown. Put 8pcs
M5 T-nuts in below positions. Apply 3mm thick foam tape to the frame for
sealing as shown. Attach the front door onto frame by screws. Apply 3mm thick
foam tape on side panels as shown. Put 6pcs M3 T-nuts in the side of frame.
Attach the side panel onto frame as shown. Install the top panel as shown.
Remove the screw in below position. Connect the two ribbon cables according to
the label behind screen, then mount the screen by screw. Install four corner
guards. Put the shaft into Z axis limit block. Rotate four foot pads to level
the machine and lock the pads by the nuts as shown.
