Attach a Pulley [HD-MS0033] to a Motor [EL-MT0029] offset the pulley from the face of the motor 13mm. Use the printed jig to ensure consistency. Verify that the flat portion of the motor shaft lines up with the flat portion of the jig.
Ensure one of the pulley set screws is aligned with the flat segment of the motor shaft, secure pulley in place with the two set screws already installed in the pulley, tighten to 3 in*lbs.
Align the Z-Motor with the Z-Lower Left (orientation is critical) the motor connector is to be facing toward the right of the Z lower left part.
Attach the motor to the Z lower left using 4x- M3x12 BHCS [HD-BT0146] with 4x- M3 washers [HD-WA0038] , tighten screws to 5 in*lbs.
Align and install the Bump Stop [PP-GP0332] with the mount located in the middle of the X-End Motor assembly [PP-GP0130] as pictured. The Bump Stop should be oriented with the flat side facing away from the belt path. Secure the Bump Stop with 2x- M2x10 SHCS [HD-BT0107] with M2 washers [HD-WA0012], tighten screws until the Bump Stop no longer moves freely.
Cut a belt [HD-BL0033] straight with the the teeth of the belt and insert one end into the top slot of the BLANK. [reference#1] then continue pushing the belt until the end come out of the front slot.
Once the belt is routed through the top and front slot on BLANK slide the Belt Tensioning Collar [PP-GP0107] over the belt.
Make sure to pinch the two sides of the belt together to lock the teeth and prevent slipping
See attached picture [reference#2]
Place 2x M3 Nyloc Nuts in the two hex holes on the X-End Motor assembly
Then Using 2x SHCS M3x30 [HD-BT0042] with 2x M3 Washers [HD-WA0038] attach the BLANK to the X-End Motor assembly. [reference#3]
Note: Stop once the bolts are fully through the nyloc nuts
Attach both cable chains to the X-End Motor assembly using 2x M3x6 FHCS [HD-BT0128] for each chain. The three wire segment on the motor side of the X-End Motor assembly and the five wire segment on the bushing side.
Next align and install the Z-Max End Stop switch [EL-SW0022] with the switch mount located above the motor mount. Secure the switch with 2x M2x10 SHCS [HD-BT0107] and M2 washers [HD-WA0012], tighten screws to 3 in*lbs.
The Cable Tie placement guild show where to start the cable tie and where the final position of the head of the cable tie should be. Start by feeding the tail of the cable tie through the circled hole and make sure the head of the cable tie is by the corresponding arrow. The placement order for the cable ties is RED, YELLOW, then GREEN
Follow the RED Circle and Arrow
Using 1x Cable Tie [HD-MS0058] secure the two lower wires. The cable tie head must be by the RED arrow.
Then pass the X-Motor Cable underneath the three extruder harness cables
See attached picture [reference#4]
Then bend the two outside tabs on the Switch and connect the white and yellow wire (Yellow wire goes to the tab by the button on the switch
Follow the YELLOW Circle and Arrow
Using 1x cable tie [HD-MS0058], secure the five wires to the cable mount area nearest the Motor mount. The cable tie head must be by the YELLOW arrow See attached picture [reference#5]
Make sure the X Motor wire is crossed under the other wires
Follow the GREEN Circle and Arrow
Then with a cable tie [HD-MS0058], following the GREEN circle and arrow secure the three wires to the cable mount area above the cable tie securing the two wires. The cable tie head must be by the GREEN arrow See attached picture [reference#6]
[reference#7] Shows where the cable ties head should be located
With a cable tie [HD-MS0058] secure the Z-Max Endstop wires along the edge of the x end motor as pictured. [reference#8]
Be sure the cable tie is under the quick connect terminals on the endstop side and the wire is on the *FRONT of the printed part.
Cut all cable ties flush, assembly should look exactly as pictured.
Note: The X motor cable's heatshrink should be aligned with the back of the X-End Motor assembly as pictured.
Attach a pulley [HD-MS0033] to a motor [EL-MT0029] , offset the pulley 6mm from the face of the motor, ensure one of the pulley set screws is aligned with the flat segment of the motor shaft, secure pulley in place with two set screws already installed in the pulley, tighten screws securely.
Bend the terminals of the Z-Max Endstop Switch outward to make space for the X-Motor, as pictured.
Attach the motor (with the connector oriented down toward the bottom of the X-End Motor assembly) to the X-End Motor assembly with 4x- M3x12 SHCS [HD-BT0039] with M3 washers [HD-WA0038], tighten screws in 8 in*lbs.
Remove the lower right phillips head screw from the back of the motor just installed [reference#9], install the screw into the ring terminal from the X Motor cable, re-install the screw until the head is again recessed and tight.
Connect the JST connector to the motor as pictured.
Using an 8mm part reaming tool, ream the 8mm smooth rod hole on the Z-Lower printed part [PP-GP0310] that has the M3 insert.
Do NOT ream the slot; this can damage the dowels and the reaming tool, keep the tool straight and to not remove too much material which would result in a loose fitting rod.
Do Not touch the reaming tool to the motor
Install two Smooth Rods [HD-RD0035] into the Z-Lower [PP-GP0310]
Install the X-End Motor assembly (with cables, switches, and motor attached) onto the Z Lower Left and Smooth Rods assembly as pictured.
Using an 8mm part reaming tool, ream the two 8mm smooth rod holes on the Z-Upper Left printed part [PP-GP0309].
Note:Take care to keep the tool straight and to not remove too much material which would result in a loose fitting rod.
Install the Z-Upper Left [PP-GP0309] to the end of the smooth rods opposite the Z-Lower Left assembly as pictured.
Install two M3x6 Set Screws [HD-BT0012] to the Z-Lower Right near the smooth rods, do not tighten.
Route the belt (attached to the X-End Motor assembly during step 3) down around the Z-Left Motor and up through the hole in the X-End Motor printed part (behind the X-Min Bump Stop).
Continue through the bearing in the Z-Upper so that the belt makes a loop back to the X-End Motor printed part.
Ensure the belt has not been twisted during this process.
Slide one Belt Tensioning Collar [PP-GP0307] onto the belt with the narrow end of the collar facing the Z-Upper.
Slip the belt through the upper slot in the Z-Belt clamp feature, see [reference#10]
The belt should be left loose at this time, secure it in place with one Z-Belt Clamp [PP-GP0308] and two M2x6 SHCS [HD-MS0230] with M2 washers [HD-WA0012]
