9 - Positron V3.2 - Final Assembly

Part Fan Enclosure x1

Bowden Guide x1

Toolboard Cover x1

Install M2.5x3x4 heatset inserts into the printed fan enclosure and guide as shown in the pictures.

Install the Z column to the Z joint base block using the thumbscrew.

Load M4 hex nuts into the slot.

Secure the right Z joint plate to the extrusion using M4x10 BHCS screws.

Position MR85ZZ bearings and planetary gears on the shaft.

Put the planetary cover on.

Install the motor to the extruder and secure with M3x20 BHCS screws.

Refer to this picture for motor wire orientation.

Install the ziptie holder to the base plate and secure with an M3x6 BHCS screw.

Route the belt of the Z drive as shown in the pictures.

Make sure the belt end on the bottom of the retainer block is short to avoid the risk of belt being jammed into the idler.

Connect the bed cable to the bed breakout PCB and secure the cable to the bed cable guide using zipties.

Position the washers and idlers in the order as shown in the picture on the carriage block. Secure them using M3x16 wafer head screws.

Insert an M3x12 wafer head into the idler and the washer. Position them to the end of the linear rail and secure with an M3x6 standoff.

Repeat the steps to prepare the other end of the linear rail.

Install H4.75xM3x12+4 standoffs into the carriage block of the linear rail.

Position the linear rail to the standoffs and make it perpendicular to the Y rail using the squaring jig. Secure with M3x8 SHCS screws.

Refer to the pictures for belt routing.

The belt goes into the hole of the printed part. (In order to give a better view, the hotend is not shown in this picture. It should be in place.)

You have to tighten the belt. When you think the belt is not loose, add an M3x10x1 washer on the belts and install an M3x6 FHCS screw to secure the belts.

Position the 5015 fan into the part fan enclosure.

Place the toolhead base plate onto the carriage block of X linear rail and secure with M3x6 FHCS screws.

Place the fan and toolhead cover plate on top of the base cover and secure with M2.5x20 FHCS screws.

Secure the plate to the heatsink with M2.5x6 FHCS screws.

Position the bowden guide between plates and secure with an M2.5x6 FHCS screw.

Secure the toolhead PCB to the side of the toolhead with M2.5x4+4 standoffs. Be careful scewing the standoffs and don't scrape other components on the board.

Refer to the pictures for toolhead PCB wiring.

All the wires should go behind the toolhead PCB.

Put the toolboard cover on and secure with M2.5x6 BHCS screws.

Position the bed V holder to the bed carriage block and secure with M6x17 thumbscrew.

Cut a 10x8mm piecce of the silicone strip and stick it to the most upper left spot on the glass bed as shown in the picture. (The pad is used to protect the melted filament from overflowing, If you don't need it, you can skip this step and following macro step.)

Insert the glass through the slot of the printed retainer rings and connect the pins with the bed breakout PCB.

Connect the touch panel to your printer and power it on. Run the Nozzle Dock macro, and the toolhead will move to the most upper left, and the bed will move downward to the nozzle. Make sure the nozzle touches the center of the silicon pad. You can adjust the position of the silicone pad as needed.

You now have completed the assembly of the Positron V3.2.
