Sovol SV05 MGN12H Linear Rail Adapters

Replace the V-Slot-Rollers on your Sovol SV05 with MGN12H linear rails using these adapters. The belt tension on the Y axis will increase slightly with this mod, but this shouldn't be an issue. You will need some additional hardware to assemble everything:

Required Hardware:

• 2x MGN12H 350mm (for Y axis)
• 1x MGN12H 300mm (for X axis)
• 4x M4x4x6 heat set inserts (for Y axis)
• 2x M5x6x7 heat set inserts (for X axis)
• 4x M4x6 screw
• 2x M5x8 screw
• 12x M3x8 screw

Print instructions:

Print the parts on the flat side with the 4 smaller holes. The parts are in the wrong orientation by default.

• Linear Rail Mount Y: print 2x
• Linear Rail Mount X: print 1x
• Line Width: 0.4mm
• Layer Height: 0.2mm
• Shells/Walls: 3-4
• Infill: 20%-40%

Depending on the filament you are using (PLA+ works for me, ABS would be optimal. PETG can work, but it may be too flexible, Nylon deforms due to mechanical stress) you can increase the wall count and infill.

Assembly:

Important: Try to keep the belts on the Y axis plates, this will save you some time aligning everything later.

1. Install the heat set inserts, the M4 ones are for Y, the M5 inserts are for X
2. Remove the wheels
3. Mount the linear rails to the outside of the frame for the Y axis (use a mounting guide to center them on the extrusion)
4. Mount the linear rail on top of the X axis extrusion
5. Make sure the carriages slide freely
6. Mount the adapters on the linear rail carriages using 4 M3x8 screws each
7. Fix the Y axis using the M4 bolts
8. Fix the X axis using the M5 bolts (you might have to remove the extruder assembly from the carriage plate)
9. DON'T TIGHTEN THE Y ADAPTERS YET
10. Make sure everything moves smoothly by moving both axes a few times back and forth
11. Tighten one side of the Y axis
12. Repeat step 10.
13. Tighten the other side of the Y axis
