Assembling Frame

In this step, you will assemble the main frame of the machine.

  1. Remove the left and right leg assemblies from the second tray. Left leg Assembly Right Leg Assembly

  2. Remove the two aluminum rails from underneath the cable chain in the first tray. Removing cable chain Removing front and back rails with feeders attached

  3. Remove the X gantry assembly from the second tray. Removing X gantry assembly

  4. Stand the left and right leg assemblies upright on the tabletop as shown below. The left leg assembly has a cable harness labeled Y1, and the tensioner arm pivot is on the left. The right leg assembly has a cable harness labeled Y2 and the tensioner arm pivot is on the right. Check the photos below for reference. Left and right leg standing on table Left leg assembly ready Right leg assembly ready Correct orientation of leg assemblies Left leg with Y1 connector Right leg with Y2 connector

  5. Remove two M5x10mm socket head screws and two t-slot nuts from your hardware bag. Leg screws and nuts

  6. Insert one of the M5x10mm screws into the front left leg as shown. Inserting screw through hole Screw ready for slot nut

  7. Attach a t-slot nut onto the screw. Make sure that the nut is oriented vertically as shown in the images below. Slot in t-slot nut Correct orientation of slot nut Incorrect orientation of slot nut Correct orientation again

  8. Find your front rail. This is one of the two aluminum extrusions you removed from the packaging earlier. It only has one right-angle bracket attached to each side instead of two. Front rail with feeders One angle bracket attached to front rail

  9. Align the front rail and left leg subassembly as shown in the image below. Make sure that the rotation of the t-slot nut in the front rail matches with the image as well. It should be perpendicular to the axis of the front rail. Aligning the front rail

  10. Rotate the front rail upward as shown in the pictures below. Make sure the t-slot nut in the bracket on the front rail fits inside the bottom extrusion of the left leg subassembly. The front rail and right angle bracket should sit flush against the extrusion. Positioning the front rail Positioning the front rail 2 Front rail ready to slot in

  11. Slide the front rail into the front left leg. Make sure it's completely pushed into the leg with no gaps. Tighten the two screws shown below to hold the front rail in place. Front rail ready to slide in Front rail slid into place Screw to lock front rail Tightening the screw Tightening the leg screw

  12. Attach the remaining M5x10mm socket head and t-slot nut into the front right leg in the same way as you did for the front left leg. Screw and nut ready Attaching screw and nut Positioning screw and nut

  13. Place the front and right leg subassemblies upright as shown in the image below. Front rail ready for assembly

  14. Ensure the t-slot nut on right side of the front rail is oriented as shown below. Lift the front rail up into the bottom extrusion of the right leg subassembly, and slide it towards you into the front right leg as shown. Tighten the front screw in place. T-slot nut rotated correctly Positioning front rail over right leg Positioning front rail over right leg 2 Front rail slid into place Tightening front rail screw

  15. Lift up the machine onto its back legs, and tighten in the final loose screw. Lifting Lumen onto back legs Lumen on its back legs Tightening the last front rail screw

  16. Find the back rail. This is the remaining aluminum extrusion that you removed from the first tray. It should have two right angle brackets on each side. Align the t-slot nuts perpendicular to the rail as shown in the image below. Do this for both sides. Back rail Correct t-slot nut alignment on the back rail

  17. Place the back rail across the back legs as shown. Rotate it upwards into the bottom extrusion of the left leg subassembly, ensuring that both t-slot nuts fit into the v-slot. It should be flush against the rail. Aligning the back rail to the machine Back rail flush against machine

  18. Make sure that the right side of the back rail has fit into the right leg extrusion. You might find that the back legs need to be pulled together or apart a little in order to get them to fit; this is ok. The back rail should be flush with the extrusion if the t-slot nuts have been inserted into the extrusion correctly. Misalignment in the legs and the back rail Correct alignment between back rail and legs

  19. Slide the back rail up and let the left side of it rest on the spacing bracket included in your tool kit. Make sure it's resting on the short side (50mm). Lightly tighten the top screw on the left side, making sure to keep the end of the extrusion and right angle brackets perfectly flush with the side of the extrusion. Note that you may need to loosen the screws a little to back them out of the bracket before tightening the assembly together.

  20. Use the bracket to set the spacing on the right side, and tighten both screws into place. Make sure the right angle brackets are perfectly flush with the right side extrusion as well. Go back to the left side and tighten the bottom screw. Using the short side of the bracket to align the back rail 2 Aligning the bracket correctly flush Tightening bottom screw

  21. Bring your machine back down onto four legs and get the X gantry assembly (shown below). Lowering the machine to the table Upright LumenPnP

  22. Slide both Y gantries to the back of the machine (opposite the tension arms), and drop the X gantry assembly onto them as shown. Make sure the toolhead motors are facing you like the image below. Y axis gantries at rear of the machine X axis attached to Y gantries

  23. Attach the X gantry to the Y gantries by installing a M5x25 socket head screw and M5x16mm socket head screw into the two holes on each side of the X gantry assembly. Inserting screws to attach X gantry M5x25 screw in lower slot M5x16 screw in upper slot Tightening the screws

  24. Install front-leg-extension onto front left leg and front right leg with 2x M5x16 socket head screw per leg Front leg extension and screws Installing extension with screws Tightening extension piece Final leg extension assembled

  25. Install a back-leg-extension onto each back leg with 1x M5x16 socket head screw per leg Back leg extension (with screws) Back leg extension positioned Screwing in back leg extension Back leg extension installed Back leg extension installed 2

  26. Your machine frame is done! Final machine frame
