Feet
- 3/4″ (M4 X 20), *-Foot_2018, screw and lock nut, leg rail. ___
- Insert the previously cut Leg into the Foot Bottom and loosely add the 3/4″ (M4 X 20) screw and lock nut. This will get tightened during the final step. ___
Bottom Corner and Lock Corner
- Bottom_Corner and Lock_Corner parts or BottomM_Corner and LockM_Corner, ¾″ (M4 X 20) Scew and nut, optional Cyanoacrylate Glue. ___
- Use the matching Bottom_Corner and Lock_Corner parts or BottomM_Corner and LockM_Corner parts. The direction of the letter will match when assembled of the correct set.
- Optional but suggested, add some glue to these parts before screwing together for added rigidity.
- Put the screw 3/4″ (M4 X 20) in from the corner piece and the nut into the lock and hold with a socket or pliers. This screw can get snugged down. ___
Leg Assembly
- 3/4″ (M4 X 20) screw and nut, previous assemblies. ___
- Assemble the corners on to the Bottoms, add the screw 3/4″ (M4 X 20) and nut (nut goes in the hex shaped hole).
- Leave these screws loose, they will get snugged up in the final step.
- Repeat this for all four sets. ___
Roller Assembly - Fixed Bearings
- Use the 1.25″ (M8 X 30) bolts, lock nuts, 608 bearings, and the Roller or RollerM. ___
- Nuts are best facing towards each other, unless you plan on adding mid span supports then the other way could get you some extra clearance.
- These can get snugged up, don’t crack the plastic, just snug.
- Do this for all 4 sets. ___
Roller Assembly - Tension Bolts
- 2.5″ (M8 X 65) bolt, 608 Bearings, Roller or Dual plates. ___
- Use the 2.5″ (M8 X 65) bolt, run it through the Roller Plate (or the dual plates).
- After the Roller plate add a 608 bearing.
- Add the plate and bearing stack into the Roller from the single bearing side. Only part way
- Add a Bearing into the center of the roller, and thread the bolt the rest of the way into the roller.
- Pay attention to the direction of the plate, the stand offs should face the bearings, and the extra notches should face the single bearing.
Rollers on Rails
- Previous assemblies, 5/16” (M8) Nylock nuts, X or Y rail. ___
- The nut for the 2.5″ (M8 X 65) bolt should be left extremely loose almost touching the roller but not all the way.
- Make sure these nuts don’t interfere with the small nut slots, if they do put the small nuts in now.
- Put all the rollers on their rails and make sure they all slide equally well. There should be tension when inserting the rail and all the bearings should touch. ___
Roller Matched Pairs
- This is showing the pairs for the X and Y axis. It should be one Roller and one RollerM. It does not matter which way the gantry rail angle is facing as long as it is facing the same as its counterpart.
- Roller and RollerM are just a mirrored set, made to help with printer deficiencies. Each axis gets one of each and the need to look mirrored (angle on the same side).
- When using the optional Dual plates, the long side should face X0 Y0 (nearest left corner) __
Lower Corner Assembly
- Previous assemblies, Spacer_corners ___
- Add your Y rails and rollers to the corner assemblies (front to back axes).
- Make sure the angled belt brackets face out, and the angles are pointed towards each other. ___
- Lay a Spacer_Corner on the rail. ___
- Lay the X rail and rollers on next (Right to left axes). ___
Full Corner Assembly
- Top_Corner pieces, 3/4″ (M4 X 20) screws, and nuts. ___
- Put on the Top_Corner pieces.
- Make sure the brackets are facing out, and the angles towards each other.
- Add the four screws 3/4″ (M4 X 20), and nuts.
- Leave the screws loose.
- Assemble all the corners.
- There will be a 2+mm gap all the way around. ___
Check Base Dimensions
- Set all your outer dimensions from corner to corner, Usually this is the same as your x and Y Rail length that was entered into the calculator.
- Lightly snug up the Top_Corner screws trying to keep the spacing even on all four sides of the part. The parts do not require very much torque the design holds the rails well.
- There will be a 2mm+ gap all the way around.
- Double check your dimensions, Be as accurate as possible. ___
