Obtain a completed Frame Assembly [AS-PR0139]
Place the completed frame on the granite block and verify that it sits flat and and doesn’t teeter, like a chair with one short leg.
Line up the square along both ends, perpendicular to the length of the frame, as pictured. Examine the relationship between frame and square. If at any point the gap meets or exceeds 2mm, the frame must be rejected for re-squaring.
If the frame has passed inspection, place it on your workbench with the back of the machine facing you.
Wipe down the smooth rods to ensure they are free from any contaminants.
Move both sides of the Z-Axis (X-Ends) to the top of travel by grasping the printed part and pushing it upwards.
Obtain one 12mm Smooth Rod [HD-RD0066] and slide it through the lower 12mm hole of the X Idler End from the outside of the frame, stopping about half way.
Place the double bearing side of the X Carriage Assembly [AS-PR0145] onto the smooth rod end inside the frame, oriented as pictured.
Install one X Bump Stop [PP-GP0377] onto the 12mm Smooth Rod end after the X Carriage Assembly.
Continue sliding the 12mm Smooth Rod [HD-RD0066] into the lower 12mm hole of the X Motor End until the end of the rod is flush with the outside of the X-Idler End (right side of frame).
Torque both lower smooth rod set screws (located on the underside of the X-Ends) to 3in*lbs.
Push the X-Bump stop into place against X-End Motor, ensure it mates flush with the printed part.
Push the axis to the middle of travel (mid-frame) by applying even downward force on the X-Ends.
Rotate the frame so the back is facing you, then orient the X Carriage Assembly [AS-PR0145] upright as pictured.
Straighten the X Axis drive belt attached to the X Carriage Assembly and route the end through the X-Idler End, beginning above the bearings with the teeth of the belt facing down.
Ensure there are no twists in the belt
Continue routing the X Axis drive belt back through the X-Carriage Assembly below the tensioner and behind the Interface Board Mount.
Route the drive belt around the X Motor pulley, beginning from below the pulley with teeth facing up.
Route the belt through the clamp feature of the X-Carriage as pictured.
Place one X Belt Clamp [PP-GP0380] into the feature as pictured and thread one M3x16 SHCS [HD-BT0185] with washer [HD-WA0038] into the insert from above.
Using a pair of pliers, remove slack from the drive belt by pulling on the end. Do not tension the belt at this point, only remove the slack.
Torque the X-Belt Clamp fastener to 5in*lbs
Wipe down the smooth rods to ensure they are free from any contaminants.
Push the axis to the bottom of travel so that both ends rest upon the Z-Lowers.
Obtain one 12mm Smooth Rod [HD-RD0066] and slide it through the upper 12mm hole in the X-Idler End from the outside of the frame.
Continue through the upper bearing of the X-Carriage and into the upper 12mm hole of the X-Motor End until the end of the smooth rod is flush with the outside of the X-Idler End.
Torque both upper smooth rod set screws (located on the top side of the X-Ends) to 3in*lbs.
The X-Axis bushings have compression features that allow the printed part to be tightened on the bushings to prevent unwanted motion.
Tighten the lower X-Axis compression bushing by tightening the flat head fastener on the bottom front of the carriage.
Tighten until you can no longer tilt the bushings on the rod, but ensure the bearing can still slide freely left to right.
Do the same for the upper X-Axis compression bushing by tightening the flat head fastener towards the top front of the carriage.
Now we will set the alignment between the upper/lower X Axis bushings.
Slide the X Carriage to the left end of travel against the X-Motor End and tighten the left button head fastener on the front of the carriage.
Torque to 5in*lbs
Slide the X Carriage to the right end of travel against the X-Idler End and tighten the right button head fastener on the front of the carriage.
Torque to 5in*lbs
You will need a Gates 508C Sonic Tension Meter on setting number 7
Tighten the X-Belt Tensioner fasteners in even increments until the target tension is reached.
Target: 23-45N
Always ensure measurements are taken at the middle with the X Carriage in the middle; measure the long portion of the belt (closest the lower smooth rod). The portion of belt being measured should not contact anything while being measured; this will cause inaccurate measurements.
Once tension on the belt is properly set, cut off the excess belt from both sides of the part but leave approximately 10mm protruding from the motor side. This allows for grip should the belt tension need adjusted post-assembly.
Set the frame with the front facing you on its left side, towards the side or rear of your workbench.
Obtain one Control Box Assembly [AS-PR0120]
Place the Control Box Assembly cover side down on the workbench with the screen facing you.
Pick up the frame (still with front side facing you and the left side facing down) and place it on top of the Control Box Assembly.
The Z-Max wires will rest in the groove as pictured, ensure they are not pinched when installing the Control Box Assembly.
Place one Stainless M5x10 BHCS [HD-BT0225] with M5 Zinc-plated washer [HD-WA0007] into the metal case mount along the front extrusion to your left.
You will need to lift/hold the frame slightly to insert the fastener, you may also need to loosen the fastener attaching the bracket to the frame to align it with the threaded hole in the Control Box
Thread the fastener into the Control Box, do not tighten yet.
Secure the frame to the Control Box at the other 3 locations using three M5x10 BHCS [HD-BT0073] with washers [HD-WA0040]
Torque all 4 fasteners securing the mounts to the control box to 5in*lbs
Leave the fasteners securing the mounts to the frame loose until the next step.
Pick up and rotate the assembly clockwise 90 degrees, set it down.
Ensure all four feet of the frame and both feet on the bottom of the Control Box are resting flat on the workbench.
The Control Box should neither be too high or too low in relation to the frame assembly. Use the granite block if you are not confident in the flatness of your workbench.
Tighten all four fasteners securing the Control Box Mounts to the frame using a long shank ball-tipped 3mm hex driver. Tighten securely

Slide the Y-Axis frame forward so that the spacer jig cannot be wiggled back and forth.
Tighten the fastener securing the left table mounts to the y-axis frame.
Torque to 5in*lbs
Place the pre-cut Y-Frame square at the location shown.
Move the right Y-Axis frame forward or back slightly until it is square; you should not be able to wiggle the square and there should be no gaps.
Tighten the right chassis mount and table mount fasteners.
Torque to 5in*lbs

Rear tube from filament sensor gets black “2” label
Insert the other end of the feed tubes to their correct Idler Tube Clamps; green to left (green), black to right (black).
Move each axis through the entire range of motion while observing where the belt rides in each idler. The belt should not rub on any printed or machined parts.
The position of the Z axis belt in the idlers can be adjusted by use of the 2 set screws in the Z-Top plates behind and in front of the Z belt tension screw. If the belt is riding towards the front, tighten the set screw in front of the Z belt tension screw. If riding towards the rear, tighten the rear set screw.
X belt position can be slightly corrected by tightening one of the X belt tensioner screws tighter than the other and thus securing the belt at an angle; If riding towards the front, tighten the rear tensioner screw further than the front. If riding towards the rear, tighten the front tensioner screw further than the rear.
Final Assembly is now complete, check your work.
Place the completed final assembly on the rack of completed finals to be calibrated.
