Use a Dial Torque Wrench with a 18mm wrench head attachment and torque the Heater Block to 30 in-lbs
Verify the torque on the Nozzle as shown.
Using a 18mm wrench secure the heater block
Use a Dial Torque Wrench with a 7mm wrench head attachment and torque the Nozzle to 15 in-lbs
The zero volt sense harness needs to be attached with the external star washer, the zero volt sense harness and the M3x8 BHCS screw in this order
Install onto heater block (note orientation of heater block and direction of wire), torque screw to 3 in-lbs
Ensure the insulation is not touching the heater block
Connect the Thermistor Harness
1x- Large herringbone gear, black (AS-TH0020)
2x- 608 bearings (HD-MS0282)
3x- M8 steel washer (HD-WA0006)
1x- Extruder washer (PP-GP0060)
1x- 0.5mm shim (HD-WA0008)
1x- M8 nyloc nut (HD-NT0002)
1x- Extruder body (AS-TH0036)
Place M8 stainless steel washers over the hobbed bolt
Place 0.5mm shim over hobbed bolt
Insert extruder washer into bearing slot (note orientation of the extruder body)
Insert 608 bearing into bearing slot
Slide the hobbed bolt through the 608 bearing and the extruder body
Place 608 bearing over the threaded portion of the hobbed bolt
Place M8 stainless steel washer over the hobbed bolt
Thread M8 nyloc nut onto the hobbed bolt
Tighten M8 nyloc nut with a 13mm wrench
Tighten until m8 washer is snug and doesn't move on it's own
Mount the motor to the body (note the orientation of the motor and harness connection point)
Place the M3x12 SHCS with black oxide in the three holes that line up with the tapped holes in the motor
Note: the large gear and the small gear need to be mated together in a way that there is easy rotation but won't have any free movement known as “slap” between the gear teeth. To test for proper alignment of gears - tighten your screws down to 3 in/lbs, Hold the small gear firmly with your finger and thumb, and try to move the large gear back and forth to see if there is any small movement between the teeth of the gears. Rotate the large gear ¼ turn and repeat this process multiple times to ensure alignment. If there is movement the small gear and large gear need to be moved closer to each other. To do this you need loosen the M3 screws ¼ turn counter-clockwise and push the motor closer to the body. Repeat until you have desired the results, tighten screws once the fit is correct.) Torque to 3in*lbs
Insert the hot end into the slot of the mount plate (note orientation of the mount plate and hot end)
Install the Hot end onto the extruder mount using the M4x20 SHCS and M4 black oxide washers
Run filament through the body to help align the Hot end
Tighten the M4 screws to 8in*lbs
Ensure the heater block part of the Hot end is square with the mount plate
Pull filament out to insure the hot end is aligned
Attach the fan with the shorter wires to the right side of the extruder with 2x- M3x12 SHCS, note fan orientation and wire orientation
Tighten screws to 3 in*lbs
Attach the fan with the longer wires to the left side with 2x- M3x12 SHCS, , note fan orientation and wire orientation
Tighten screws to 3 in/lbs
Feed the yellow and purple wires through the opening between the right fan duct and the Hot end
Feed a cable tie through the slot as shown
Tighten the cable tie around the fan harness and clip-off excess cable tie
Attach the Pelonis 5V 40mm fan onto the heat sink fan mount using 4x- M3x12 SHCS (note orientation of fan and wires)
Tighten screws to 3 in*lbs
Install the M3x25 with M3 black oxide washer into the side hole
Wrap the harness coming from the fan over the M3x25 SHCS, around the front and under as shown
Install the assembled heat sink fan duct to the extruder mount
Ensure all harnesses are running through the opening that the 5V fan harness is running through
Tighten down the fan duct, being careful not to squish any wires, tighten screw to 3 in*lbs
When the MOARstruder Assembly is complete, use the Tool Head Test Fixture to Calibrate the E-Steps.
Install the MOARstruder into the test fixture as shown.
Insert test filament (T-Glase), use 300mm PTFE guide tube to measure 300mm from the top of the Idler Block and mark where the PTFE tube ends.
Turn on power.
Select 300mm spit test gcode as shown.
Note: Be aware that 300mm spit test also includes tests for 24v fans. 5v fan should be operational when power is applied to the Tool Head.
Ensure that exactly 300mm of filament was extruded when test is complete by verifying that the mark is flush with the top of the Idler Block as shown.
After E-Steps have been verified, remove MOARstruder from test fixture and place E-Step Calibration (with E-Step value) on the rear of the Tool Head.
