Using 4x M3x8 BHCS [HD-BT0137] with washers [HD-WA0038] secure the Y-Axis Idler to the Bottom Plate
Make sure the front of the Idler printed part remains flush with the idler mount of the Frame. It should be centered between the left and right sides of the mount as well.
Torque fasteners to 5in*lbs
g) Rotate the frame so that the rear of the frame is facing you.
Lean the frame away from you to expose the screw locations for the Y-Axis Rod Mount
Secure the Y-Rod Mount to the Motor mount flange of the bottom plate using 4x M3x8 BHCS [HD-BT0137] with washers [HD-WA0038]
Make sure the back of the Y-Axis Rod Mount printed part remains flush with the motor mount flange of the Frame. It should be centered between the left and right sides of the mount as well.
Torque fasteners to 5in*lbs
a) Install a Pulley [HD-MS0033] to the shaft of a Motor [EL-MT0029] using the printed spacer jig to offset the pulley 2mm from the face of the motor.
Align the first set screw to be tightened with the flat side of the motor shaft, tighten both set screws securely.
b) Align the motor with the Y-Axis Motor mount of the frame with the connector oriented as shown
Secure using 4x M3x6 BHCS [HD-BT0140] with washers [HD-WA0038]
Torque to 5in*lbs
c) Flip the frame over so that it rests on the top plate.
Route the Y-Axis Motor lead through the hole in the rear of the bottom plate.
Remove the phillips head screw from the bottom of the motor, closest to the frame and connector
Install the terminal ring to the screw and re-install the screw, ensuring that it again becomes recessed and tight.
d) Connect the JST connector to the motor as pictured
Secure the Y-Axis Motor lead to the frame utilizing the two small holes in the bottom of the frame and a cable tie [HD-MS0058]
The cable tie latch must be on the bottom of the frame.
a) Flip the frame back upright and rotate if necessary so that the Y-Axis Idler is facing you.
Using a 2mm hex driver, tighten the double bearing holders to the Bed Plate, beginning with the left two flat head screws (1 & 2)
Then tighten the two M3x8 BHCS directly to the right of the two flat head screws (3 & 4)
Slide the bed towards the rear and tighten the back right M3x8 BHCS securing the right double bearing holder to the bed plate (5)
Slide the bed towards you and tighten the front left M3x8 BHCS securing the right double bearing holder to the bed plate (6)
Tighten the remaining two M3x8 BHCS (7 & 8) and torque the six button heads to 3in*lbs and the two flat heads to 5inlbs.
b) Slide the Bed Plate back and forth and ensure that motion is smooth from end to end without binding. If stiffness or binding occurs it may be necessary to loosen and re-tighten the bearing holders while moving the Bed Plate, this helps align the bearing holders with the smooth rods.
Using the force gauge, measure the carriage drag as shown. If the drag is above 15N, check the individual bushing drags. If needed, carefully broach the bushing set to reduce the drag with the special broaching tool for a maximum of one pass.
a) Secure the Z-Right Motor cable to the bottom frame plate at the location shown.
The latch should be on the bottom of the machine.
b) Secure the Y-Motor cable to the side of the cable chain as pictured.
c) Ensure cables inside the cable chain are not overlapping or twisted
d) Gather the Y axis cable harness (excluding Z-Left motor lead) and secure to the location shown, the zip tie latch should be on the bottom of the frame.
e) Ensure sufficient slack at the motor connections is given to prevent damage and accidental unplugging.
a) Place the Z Axis left assembly into the frame assembly
b) Secure the Z Lower left of the Z Axis left assembly to the frame assembly with four M3 x 6 mm flat-head socket cap screws using a 2.0 mm hex driver, torque to 5 in*lbs
c) Secure the Z Upper Left of the Z Axis left assembly to the frame assembly with six M3 x 6 mm flat-head socket cap screws using a 2.0 mm hex driver, torque to 5 in*lbs
d) Run the end of the X Harness with the ferrite through the Upper Strain Relief
e) Attach the X/Extruder Cable harness to the cable chain mount on the Upper Strain Relief
f) Ensure the Z-Axis Smooth Rods are not making contact with the Z-Motor, this can cause unwanted noise/vibration, there should be a 2-3mm gap between the motor housing and the bottom of the smooth rods.
Torque the lower smooth rod set screw to 3in*lbs as pictured.
Torque the upper smooth rod set screw to 3in*lbs as pictured.
a) Place the Z Axis right assembly into the frame assembly
b) Secure the Z Lower right of the Z Axis right assembly to the frame assembly with four M3 x 6 mm flat-head socket cap screws using a 2.0 mm hex driver, torque to 5 in*lbs
c) Secure the Z Upper right of the Z Axis right assembly to the frame assembly with six M3 x 6 mm flat-head socket cap screws using a 2.0 mm hex driver, torque to 5 in*lbs
d) Ensure the Z-Axis Smooth Rods are not making contact with the Z-Motor, this can cause unwanted noise/vibration, there should be a 2-3mm gap between the motor housing and the bottom of the smooth rods.
Torque the lower smooth rod set screw on the Z-Lower to 3in*lbs as pictured
Torque the upper smooth rod set screw on the Z-Upper to 3in*lbs as pictured.
a) Flip the assembly upside down so that it rests on the top frame plate with the Y-Idler to your right.
b) Cut the Timing Belt [HD-BL0033] at an angle to assist feeding through the Y-Idler.
c) Insert one end of the belt and feed it through the right side of the adjustable y-belt mount [PP-IS0076] with the teeth pointing towards the post , as shown
Loop the end of the belt around the post and apply pressure so that the teeth are able to engage each other
While applying pressure pull the other end of the belt make sure that the teeth are catching, the end of the belt should be pull through the slot as shown
d) Make sure that the 2x nyloc nuts [HD-NT0001] are still in the nut traps on the adjustable y-belt tensioner
e) Mount the adjustable y-belt mount to the bottom of the bed using 3x M3 x 8 BHCS [HD-BT0137] and 3x M3 washers [HD-WA0038]
f) Loop the belt around the y-motor idler bearings and then backing around the timing pulley on the back of the assembly
g) Finish describing when I have pictures
Verify that what you've assembled matches the picture at right.
