Ce dont vous avez besoin
-
-
Using a 8mm open end wrench, loosen the bottom inner wheel eccentric locknut. Back it off a few turns.
-
Using a 7mm closed end wrench hold the nylock nut on the front of the X/Z bracket and loosen the eccentric wheel shaft with the M2.5 hex.
-
Fully remove both lower inner wheels. They will not be used.
-
-
-
Unplug the X End Stop then the X Motor (this can be done before or after X Axis removal depending on your access)
-
Remove the assembly by loosening the cap screws from the back of the machine. The T nuts just need to align parallel to the slot.
-
Be sure the X Motor is unplugged
-
-
-
Use a knife to open the box and remove the foam bundle. There are rubber bands to keep it all together during unboxing. Remove the rubberbands and set aside. Please repurpose them.
-
Remove the top foam to reveal your Linear Rail Upgrade! You should have received everything needed to install the upgrade.
-
1 Assembled Linear Rail Upgrade
-
1 X Carriage Plate
-
1 X Axis Idler Assembly
-
8 of M3x4 SHCS (socket head cap screw)
-
1 printed motor pulley spacer
-
-
-
With M2 hex, loosen the motor pulley set screws and insert the printer spacer under the pulley.
-
With the pulley flange facing down and pinching the pulley spacer firmly, position one set screw to align with the machined flat on the motor pulley shaft and tighten that one first. Then, tighten the second set screw.
-
Install the X Axis Motor / bracket onto the new 2020 frame with the pulley facing up when the linear rail is facing forward. The end stop should be facing to the right.
-
Install the X Axis Idler Assembly by aligning the T nuts parallel to the slot and pushing it in until it stops. With an M3 hex, run the screws until they start to tighten but leave final tightening for later.
-
-
-
-
Install the X Carriage Plate. Using an M2.5 hex, start all 8 cap screws a couple threads before tightening any then tighten in an X pattern
-
-
-
Route one end of the belt through the front of the belt slot on the X Carriage Plate and fold over about ½”. Using a cable tie, secure that end in place, making sure the teeth on the belt mesh together to hold tight.
-
Run the belt around the opposite side pulley and back to the open slot repeating the process, this time pulling the belt tight with your hands or needle nose pliers before securing with a cable tie.
-
-
-
Loosen the bolts to the X Idler assembly and while pushing it away from the frame, tighten the screws. This step can be repeated once on the machine to hold things more securely and final tension the belt.
-
Add a second cable tie to both sides next to the others.
-
-
-
Plug the X Motor back in
-
Make sure the T nuts are still in place and parallel to the X Axis
-
Install the new X Axis Assembly
-
While holding in in place, tighten the right outside cap screw and make sure it clamps the assembly in place before letting go.
-
Repeat for other 3 screws
-
-
-
There are 4 cap screw/ t nuts securing the X Axis in place. Using an M3 hex key, you can tighten the 4 screws (inner and outer + left and right)
-
You can line the right side (idler) so it is flush with the X/Z bracket.
-
Next, you will need to assemble and install your extruder/ hotend setup.
