Step 1: Tools needed for this chapter
🟪 M2.5mm Allen Key
🟦 M3mm Allen Key
Step 2: Frame parts preparation
Step 3: Preparing the brackets
🟪 Take the 2.5mm allen key, the T-slot corner brackets, and the set screws and start to thread the set screws into them from the inside of the corner as shown.
🟦 You should only need to turn the screws about 2 turns until they stay in place.
🟥 if you thread them in too far and they stick out the other side and will not insert into the T-slot correctly
🟩 Repeat for the 12 gathered brackets
This step may have already been done in advance.
Step 4: Making the two halves of the frame
🟪 Take one of the 490mm and 190mm T-slots and lay them out as shown.
🟦 Take two of the corner brackets and slot them into the 490mm T-slot.
🟩 Take the 190mm T-slot and insert it onto the other side of the brackets.
🟨 Tighten the set screws until the bracket doesn’t slide around in the T-slot
Tip: you want to wait to completely tighten the set screws until the frame is fully assembled to ensure the pieces are lined up first.
🟧 Repeat with the other pair of 490mm & 190mm T-slots to form the second corner.
Step 5: Adding the cross brace
🟪 Take the 470mm T-slot, one of the frame halves from the previous step, and two corner brackets
🟦 Slide the corner brackets onto the 190mm length side of the frame half
🟩 Slide the 470mm T-slot onto the other end of the corner brackets
🟨 Tighten the set screws until the bracket doesn’t slide around in the T-slot, but not fully
Step 6: Aligning the frame pieces
🟪 Take the two halves of the frame and 6 corner brackets
🟦 Slide the corner brackets onto the second half of the frame as shown.
🟩 Start joining the halves by aligning the brackets with their joining slots.
Tip: It can be easier to align if you start in one corner and work your way around to the opposite corner.
🟨 Once aligned, slot the connectors into their destination.
Step 7: Joining the frame together
🟪 Start tightening the brackets on the corners of the frame, making sure to keep the corners aligned.
Tip: leaving the cross brace loose will allow you to slide it around to reach the corners more easily.
🟦 After tightening the corners with the 2.5mm Allen key, check that the pieces are flush with each other. You may have to loosen other corners to make sure they are aligned.
🟩 You can leave the cross brace loose for now, as it will need to be aligned later, but tighten the set screws on the brace itself.
Step 8: Arm Base parts preparation
- Gather the following:
🟪 Arm Frame base
🟦 T-slots:
- 100mm T-slot
- 120mm T-slot
- 220mm T-slot
- 280mm T-slot
🟩 16x M4 T-slot nut
🟨 14x M4 10mm screws
Step 9: Arm Base frame assembly side 1
🟪 Take the arm base plate and inspect it.
- Notice that there is a circular indention on one side of the plate.
- Put the base plate with the indention facing down.
🟦 Take the 280mm T-slot and insert 5 T-slot nuts into one side.
🟩 Place the T-slot next to the base plate and roughly align the nuts with the holes in the base plate.
🟨 Place the base plate on top of the T-slot and align one of the nuts at one end with the hole in the base plate.
- Take an M4 screw and get it hand tight in the nut.
🟧 Take the remaining four screws and hand tighten them into the other four nuts.
Tip: If you leave the screws loose, you can slide the T-slot around to help align the nuts with the holes. Additionally, you can take the 2.5mm Allen key and use it to nudge the nut into place if it’s just a little off.
Step 10: Arm Base frame assembly side 2
🟪 Take the 120mm T-slot and three T-slot nuts.
🟦 Insert the nuts into a single rail side of the T slot.
🟩 Align them with the holes in the next side of the base plate.
🟨 Take three M4 screws and attach the T-slot to the plate.
Refer to step 9 for additional tips
Step 11: Arm Base frame assembly side 3
- Take the 100mm T-slot and four T-slot nuts.
🟪 Insert two nuts in the top and bottom of the T-slot.
make sure you put them in both sides otherwise you will have to disassemble some to put them in later.
🟦 Lay the T slot next to the short side of the base plate with the large hole.
🟩 Align the nuts on one side of the T-slot with the screw holes on the side of the base plate with the large hole.
🟨 Hand tighten two M4 screws into the nuts
Refer to step 9 for additional tips
Step 12: Arm Base frame assembly side 4
- Take the 220mm T-slot and four T-slot nuts.
🟪 Insert the four nuts in the top of the T slot
🟦 Align the nuts on one side of the T-slot with the screw holes on the final side of the base plate.
🟩 Attach the T-slot to the base plate with four M4 screws.
Refer to step 9 for additional tips
Step 12: Joining the Arm base to the frame
- Gather:
🟪 the arm base
🟦 the frame that you set aside earlier in the section
🟩 4x T-slot corner brackets
🟨 8x corner bracket set screws (in the corner brackets)
🟧 2x T-slot nuts
Note which direction the large frame pieces are facing. The long side closest to the base frame should have its open end facing to the left of the base.
🟦 Insert the two T slot nuts into the upper side-slot of one of the long sides of the frame and push them to the other end.
🟩 If the set screws are not already in the corner brackets, prepare the T slot brackets as shown in step 3.
- Insert two of the brackets into the same long side of the frame in the top and bottom slots with the set screw side first.
🟨 Insert the other two brackets into the long side of the frame in the top and bottom slots with the set screw side last.
🟧 space out the two pairs of brackets to align with the T slots of the arm base.
🟥 Slide the base T-slots onto the brackets.
Step 13: Aligning arm base to the frame
- Before the screws are tightened on the brackets joining the arm base and frame, we need to make sure they are parallel to each other.
🟪 Take another piece of T-slot (any of the sizes used in the arm will do)
🟦 Insert the T slot in between the arm base and the frame.
- Adjust the position of the two T-slots going into the brackets to where they are both flush with the T-slot frame. If you can’t move the T slots in the base, loosen the M4 screws a little.
Tip: Act like you are trying to clamp the extra T-slot in place with the two frame sections.
🟩 Once the extra T-slot is flush with both the arm base and the frame, check that the longer T-slot on the base is flush with the back of the base.
🟨 Once done, fully tighten the 14 screws on the arm base.
- Tighten the four set screws attached to the base.
Step 14: Finishing the frame
🟪 While still joined with the corner brackets, slide the arm base to where it is about centered on the frame.
Don’t worry about getting this perfect now, we will align it more accurately later.
🟦 Tighten the eight set screws on the corner brackets.
🟩 It is preferred to tighten the set screws joining to the frame square before the arm base. This makes it easier to keep the base T-slots flush to the long frame piece.
Step 15: Preparing the feet
- Gather:
🟪 4x printed feet brackets (part AA)
🟦 6x feet
🟩 12x M4 10mm screws
🟨 12x M4 T-slot nuts.
Step 16: Mounting the feet brackets
🟪 Take the 12 T-slot nuts and insert three into each of the four T-slots of the rectangular frame.
- Group them up to where there are three in each corner.
🟦 Take one of the brackets and align the nuts to the holes on the bracket.
🟩 Attach the bracket to the frame with three M4 10mm screws.
🟨 Repeat this for the other three brackets.
Step 17: Mounting the feet
🟪 Take four of the feet and screw them into the corner brackets.
There may be some molten plastic in the hole from putting in the threaded insert. It should not prevent the foot from screwing in.
🟦 Take the other two feet and screw them into the M8 threaded holes on the arm base plate.
🟩 Flip over the completed frame and adjust the screw feet so that all 6 are contacting the table.
Step 18: Base frame completed!
- The base frame is done, Congratulations!
- For a final check, compare your build to the picture.
The crossbeam should still be loose, so that could look different from the image.
Double check that there are two T slot nuts in the front piece of the arm base.
- When you are ready, let’s continue to the Z-Axis Assembly.
