Route the wire leads through the hole in the drive module lowers. Mount the pulleys to all 4 motors using the alignment jig. Secure the Y motors to the drive module lowers by screwing M3xXX screws through the lower and the motor mounts, fully tightening as there will not be access to these screws later. Press the upper and lower drive module pieces into the mid accent piece, making sure the wire routing for the Y endstops is still correct. Position the X motor in place, making sure the endstop wires align in the channel. Partially screw in the M3x30mm screws to hold the X motor in place. +Follow PDF instructions in this folder, and then install each drive module onto the gantry: -Once both drive modules are assembled, mount to the printer by sliding onto the Y extrusion, and pressing backwards into the rear vertical extrusions. Note--if you cannot get the drive modules to fit due to interference with the MGN9 Y rails, loosen the MGN9 rail and slide forward slightly to give clearance. Insert the rear crossbar extrusion between the drive modules, and check drive modules, etc for alignment.

Keep the M5x50mm bolt partially loose, so the front idler halves can flex slightly when you slide it onto the Y extrusion slots. The tabs on the idlers should fit in the vertical extrusions. Lightly snug the M5x10 and M5x16 bolts on the bottom of the front idler, making sure the idler contacts both the Y and vertical extrusions, then tighten completely.

Mount the XY joint lowers to the MGN9 Y rails. Route a Y belt around the Y motor/pulley, then through the front idler, inserting the GT2 pulley in the front idler, pulling the belt into place. Temporarily insert the M5x50 screw through the front idler to hold the GT2 pulley in the furthest back position. Take the XY joint mid piece, hold the Y belt tight, and mark where the belt should be to fully insert into both grooves in the 3d printed part. Remove the Y belt, cut Y belt to length, and then cut a second Y belt to an identical length for the other side. Reroute the Y belts on both sides, inserting into the 3d printed parts. If extra slack is needed, remove the M5x50 screw for the GT2 pulley temporarily to allow the pulley to slide backwards slightly. Once the belt is inserted into the XY joint mid part, snap the mid piece onto the XY joint lower, using the locating features to hold it in place. Note, the Y idler tensioner doesn't have to be installed at this point. This will make it easier to route the X belts later. +Unlike standard Voron Trident XY joint assemblies, the Tridex XY joints must be assembled on the printer in stages.

The X belt routing is similar to a standard CoreXY belt routing, except upper belt attaches to the left X carriage (T1), and the lower belt attaches to the right X carriage (T1).

Once the belt is routed, temporarily install an X carriage and pull the X axis flush to the front of the printer, to make sure there is enough belt length. You can leave an inch or two extra belt sticking out from both ends of the belt. Cut the X belt, and then remove, and cut another X belt exactly the same length. Install both belts, making sure that both have the same amount of extra belt length extending from the X carriages. With this complete, install the M3x30 bolts through the X carriages to make sure both halves are fully secured. Remove the M5x50 SHCS from the front Y idler pulleys, and finally install the Y tensioners. If the 20T idlers are offset due to Y belt tension, use an allen key or small screwdriver to push it backwards from the bottom while you insert the M5x50 back in from the top, so the pieces fit together. -## Part 6: Tensioning and Alignment +## Part 7: Tensioning and Alignment With all belts installed, push the X axis backwards so it's about 3/4 of the way to the back of the printer. Pluck the Y belts (between the XY joints and front idlers) and tension them until there is a clear low bass tone, even on both sides. Pluck the X belts and tension them so they match the same tone. Push the X axis backwards and check to see if both Y endstops trigger at the same time--if they do not, slightly tweak the X belt tension until they do. If they don't reliably trigger, install the "Y Endstop Bumpers" (not yet designed) to improve Y endstop performance. Check all belt tensions again once both Y endstops are triggering at the same time. If the belt tensions are significantly different between X1/X2, loosen the screws connecting the X axis extrusion to the XY joints, recheck Y endstop triggering/belts, and once belt tension is the same across all belts and the Y endstops trigger at the same time, tighten the X axis 2020/XY joints for a final time. Check all structural bolts through the gantry to make sure they are moderately tight. DO NOT OVERTIGHTEN, just snug: M5x30 BHCS on Drive Modules (idler pulley axles), M5x40 SHCS holding idler pulleys on XY joints, M5x50 SHCS on Front Idler tensioners. -## Part 7: Nozzle Wiper Assembly +## Part 8: Nozzle Wiper Assembly Take the nozzle wiper components and insert two heatsets into the ends of each nozzle wiper body. Cut pieces of silicone wiper (based on template) and insert into the slots. Secure silicone pieces with M3x20 SHCS to the end of the wiper body. To mount the wiper assembly to the bottom of the XY joint, note that two of the XY Joint Lower to MGN9 Y rail screws have passthroughs in the nozzle wiper body, and two will be used to mount. Remove the two M3x16 SHCS screws (diagonally) where the nozzle wiper will mount to the XY Joint Lower, and put M3x20 SHCS through the nozzle wiper body, thorugh the XY Joint Lower, and into the MGN9 carriage. Tighten securely, and repeat with both sides. -## Part 8: Toolhead Assembly +## Part 9: Toolhead Assembly Assemble two CW2 modules per the standard CW2 instructions. Mount your choice of CAN control board to the back/sides based on the model. NEMA14 sized CAN boards can be mounted with M3 brass standoffs off the NEMA14 motor, HUVUDs/NEMA17 can be mounted with an arm that replaces the cable chain mount.
