Introduction

Please note: All measurements provided in this guide are based upon building a 300x300 V-Core 4.

If you are building a machine of a different size, the following adjustments can be made to the stated extrusion lengths:

  • 400x400: Add 100mm
  • 500x500: Add 200mm

It is strongly recommended to assemble the frame on a known flat surface (such as a solid table, work surface or similar). Assembling the frame on a carpeted floor, tile floor or other non-flat surface, can cause the finished frame to not be square. This can cause issues with print quality and performance.

  1. This step is intended to demonstrate how the quick connectors operate, the actual assembly process begins in Step 6 T-Nut Pin O-Ring

    • This step is intended to demonstrate how the quick connectors operate, the actual assembly process begins in Step 6

    • O-Ring

    • Housing

    • Set Screw

  2. This step is intended to demonstrate how the quick connectors operate, the actual assembly process begins in Step 6 The T-Nut pin is responsible for pulling the two extrusions together and ensuring a firm connection- It should be inserted inside the housing as shown. The T-nut pin groove must be below the set-screw.

    • The T-Nut pin is responsible for pulling the two extrusions together and ensuring a firm connection- It should be inserted inside the housing as shown.

    • The T-nut pin groove must be below the set-screw.

    • Upon tightening the set screw, its end will exert pressure on the sidewall of the T-Nut pin groove, causing it to close.

  3. This step is intended to demonstrate how the quick connectors operate, the actual assembly process begins in Step 6 Before inserting the housing and set screw into the extrusions, make sure the housing hole is free from the set screw. Insert the housing + set screw on the extrusion, with the set screw facing up.

    • Before inserting the housing and set screw into the extrusions, make sure the housing hole is free from the set screw.

    • Insert the housing + set screw on the extrusion, with the set screw facing up.

    • The hole on the housing should be aligned with the hole in the extrusion so that the T-Nut pin can be inserted next.

    Edit

    need a small hamer to insert the housing - hole are too small for most of them (1/10mm?)

    this tooks me most of my time to insert them

    Try both side of the hole, one side is bit looser than the other

  4. This step is intended to demonstrate how the quick connectors operate, the actual assembly process begins in Step 6 Insert the T-nut pin into the extrusion and quick connector housing The T-nut pin groove must be facing the same side as the set screw, if not, the quick connector won't work.

    • This step is intended to demonstrate how the quick connectors operate, the actual assembly process begins in Step 6

    • Insert the T-nut pin into the extrusion and quick connector housing

    • The T-nut pin groove must be facing the same side as the set screw, if not, the quick connector won't work.

    • Carefully thread the set screw in, just enough to hold the t-nut pin in the assembly. Do not tighten it, the goal is just to ensure the t-nut pin doesn't fall.

    • When connecting two extrusions, carefully slide the T-nut pin inside the slot of the other extrusion.

    Edit

    Apply a tiny amount of silicone grease to the aluminum holes. Remove the set screw. Position the connector and use a block of wood between your hand and the connector to push the connector into the hole to avoid discomfort to your hand. Rotate the connector, if necessary, with a screwdriver or needle nose pliers as needed to make it align properly in the hole. The connector has to be below flush of the extrusion so I used a C clamp and the shaft of a 3/8" drill bit to gently squeeze the connector below flush. Gently tapping the T-nut head with the block of wood will cause it to climb the ramp built into the connector for final connector positioning. Screw in the screw just tight enough to grab the T-nut so it won't fall out. Eventual apply silicone grease to the O ring on the T-nut to allow it to smoothly enter the extrusion at final assembly.

    I ran into two interference issues: first, some of my supplied quick connector housings had rough cross-drilling and needed some manual deburring to clear them enough for the pins to actually slide in.

    Secondly, maybe 1/3 of my pins were slightly to extremely difficult to get the o-ring into the extrusion end. Most I managed by manually stuffing the entire perimeter of the o-ring.

  5. This step is intended to demonstrate how the quick connectors operate, the actual assembly process begins in Step 6 When sliding the extrusion to the right place, be careful, and take it slowly so as to not damage the extrusion coating. Once the extrusions are in the right place, you can firmly tighten the set screw.

    • The T-nut pin will be pulled inside and firmly attached the extrusions.

    • Always verify the strength of the connection between the extrusions. If the connection is not strong, loosen the set screw, ensure that the T-nut pin groove is positioned below the set screw, and reconnect the extrusions.

  6. Prepare 28x Quick connectors Prepare the following extrusions with quick connectors on both sides: 3x T-Slot 3030 Milled extrusion- 440mm

    • Prepare 28x Quick connectors

    • Prepare the following extrusions with quick connectors on both sides:

    • 3x T-Slot 3030 Milled extrusion- 440mm

    • 4x T-Slot 3030 Milled extrusion - 475mm

    • 2x T-Slot 3030 Milled - 475mm with 2xM8 holes

    • Ensure the quick connector set screws are facing the same side as the M8 screw head holes.

    • 5x T-Slot 3030 Milled extrusion - 540mm

    • If you are building a machine of a different size, add 100mm to all extrusions for the V-Core 4 400 and 200mm for the V-Core 4 500

    Edit

    • If you are building a different size V-Core 4, add the following lengths to the extrusions:

    • V-Core 4 400 - add 100mm to all extrusions

    • V-Core 4 500 - add 200mm to all extrusions

    • 2x T-Slot 3030 Milled extrusion - 750mm with 3xM4 holes

    • 1x T-Slot 3060 extrusion - 540mm

    Edit

    To prevent frustration with misaligned quick-connectors, I used this trick to align them properly in advance.

    The housings fit only on one side of the extrusion, not both. On the correct side, they'll just drop in a bit without any force, just by gravity.

    - Drop in the housing into the correct hole, just let it sit by gravity, do not apply any force. You can freely rotate it to align the whole with the length of the extrusion.

    - Align the T-Nut pin with the hole to make sure the housing is oriented correctly.

    - Remove the T-Nut pin

    - Press in the housing by hand, this is likely quite hard to get in.

    - I then put in a hex-wrench into the set-screw of the housing and put the whole thing into my table-vice.

    - Check that the housing hole is still aligned in the correct orientation. If it's not, fix it now, it will be much harder later.

    - insert the T-nut pin into the center hole of the extrusion until it hits the housing

    - now slowly close down on the vice, slowly pushing in the housing. At the same time wiggle the pin.

    - Keep closing in on the vice slowly until the pin just slides in without force.

    Now your housing is properly aligned, and at the correct height

    - Make sure to hold on to the extrusion while opening up the vice again. (to prevent the extrusion getting damaged by accidentally dropping down.)

    It's easy to miss that the single 3060 extrusion and the four longest extrusions will not get any quick-connectors.

    The single printed part is in the bag labelled “Machine kit printed parts bundle SKU: HW3696MK VC4.0-PPB_04-00”. (SKU is for the 500mm kit, it may be different for other sizes.)

    Having two pieces of the alignment jig would make it much easier to align all the parts. Likely also more precise. (Would be great if the printed-parts set included two.)

    If you have access to another printer and would like to print a second one: This should be the part to print from the BOM. V-Core-4.0/PP000279-vc4_frame_jig_V01_20...

    Look in the slots to ensure the T-nut pin rotated fully as well. I had to manually turn it by sticking something in the slot and completing its rotation.

    You can find the robber grommet in a separate small bag in the large metal-hardware bag.

    It's labeled: Rubber Grommet 18×14×3, SKU:HW3783GC

    I have also 26 holes, but I have left the 8 extra holes empty, since I don't know if they will be needed later.

    Grommet hole should be on the left side when facing the front of the printer. Found the answer in the wiring section of electronics

    Need to show which side the grommet hole should be on relative to the m6 hardware direction.

    For the 500mm model:

    - the front base plate does not have a front/center hole.

    adding the 3 Z motors with cusion in this step would be far easier, in the next step you have to lift up the already assembled frame and hold them in place while trying to screw them to the cusion whil supporting the weight of the frame

    Based on Electronics section 12. Electronics the grommet on the rear panel should be on the LEFT. It's not clear from this diagram.

    Based on the hole that I have the z-axis motors going through (The one closest to the stepper motor drivers on a VCore-4 400) I have the grommet on the rear pannel being on the Machine's Right. Where did you route your stepper motors through?

Some of the T-nuts I received arent beveled enough to be useful. picture of t-nuts in question. Any way I can resolve this quickly?

Mickael van Schie - Reply

My 400mm version has no hole in the front center of the front baseplate. Is that a design revision, or do I need to grab a drill?

Also, the back plate with the new version (with grommet- it's labeled "Rubber Grommet 18x14x3" on the bag) does the hole belong on the left side when facing in from the front?

Cheers!
