Mini V Wheels
We will begin by assembling 16 Mini V wheels.
X Axis
X Carriage
Take the "x carriage - tool side" part.
Optionally, add two M3 nuts, for future use. Glue, or welding with filament and a hot tip.
Add the four M5x40mm screws.
Add the four wheels with spacers.
Add the "x carriage - nut side" part.
Ensure that all oval holes are face to face and do not overtighten the screws.
Put the assembly as pictured on a flat surface, with the oval holes at the top.
Tighten the two bottom screws firmly.
Two techniques.
1 - Slide the 20x20x426mm V-Slot profile, push the wheels down, and tighten the top screws ... sometimes it works well ...
2 - Push the wheels down, tighten the top screws a little, and gently slide the 20x20x426mm V-Slot profile. Finally tighten the top screws.
It is not always perfect, do not despair, and try again.
X End - Motor side
Follow the same setup as the x-carriage.
Add the Nema17 motor with four M3x10mm if the shaft is less or equal to 20mm, if greater use M3x12mm and add the "2mm motor spacer" as pictured. (Or cut the shaft)
Add the Z axis ACME nut with three M3x10mm. If it's hard to screw, tap the three holes.
X End - Bearing side
Follow the same setup as the x-carriage.
Add the Z axis ACME nut with three M3x10mm. If it's hard to screw, tap the three holes.
X Lead Screw
Attention, orientation of the nut is important.
Details for mounting bearings.
X Axis Assembly
Add two T-Nut on the x-end with two M5x10mm. Slide the x-end on the 20x20x426mm V-Slot profile. Adjust and tighten the screws firmly.
Slide the x-carriage on the 20x20x426mm V-Slot profile.
Add the lead screw, without securing the nut.
Add a T-Nut for X Endstop if you do not have a drop in T-Nut. And as for the first x-end, add two T-Nut with two M5x10mm and slide.
Adjust the space between the two x-end a 410.2mm and tighten the screws firmly. Do not forget to tighten the flexible coupler.
Drag the x-carriage on the bearings side. Fix the nut firmly without forcing.
Turn by hand the lead screw to move the carriage to the oposite, the force must be constant, no hard point! If all went well, the X axis is completed.
Y Axis
Y End - Bearing side
Add four T-Nut on the y-end with four M5x8mm.
Slide the y-end between the two 40x20x480mm V-Slot profile. Adjust and tighten the screws firmly.
Y Lead Screw
Same as the X axis.
Y End - Motor side
Fix the Nema17 motor on the y-end with four M3x10mm and add four T-Nut with four M5x8mm on the y-end.
Clip the lead screw assembly in the x-end and slide the motor side.
Adjust and tighten the screws firmly.
Y Carriage
Take the "y carriage" part. Add four M3 nuts.
Add two wheels with spacers in round holes and tighten the screws firmly.
Add the two others wheels with spacers in oval holes, push the wheels outwards and do not overtighten the screws.
Move the nut to the x-end (bearing side). Clip the "y carriage" on the "y assembly". Push the wheels inwards. Tighten the screws by applying pressure inwards. (Sorry I can not explain better than that.)
Drag the "y carriage" on the bearings side. Fix the nut firmly without forcing.
Turn by hand the lead screw to move the carriage to the oposite, the force must be constant, no hard point! If all went well, the Y axis is completed.
Y Frame
Prepare six 40x20mm 90° brackets with four T-Nut and four M5x8mm.
Slide on the 20x20x430mm T-Slot profile four 40x20mm 90° brackets ans four T-Nut as pictured. Currently do not tighten the screws too much, just to keep up.
Add five T-Nut at the bottom and one at the top, they serve to cable clip.
Working on a flat surface. Add the y-assembly and the two 40x20x520mm T-Slot profile. Adjust the brackets and tighten all screws firmly. Add six T-Nut at the bottom and one at the top, they serve to cable clip.
Slide four T-Nut on the 20x20x430mm T-Slot profile, fix the two 40x20mm 90° brackets. Currently do not tighten the screws too much, just to keep up. Slide four T-Nut on each 40x20x520mm T-Slot profile, they serve to Z motor mount.
Adjust and tighten all screws firmly.
Z Axis
Prepare the two 68° brackets (left and right) with three T-Nut and three M5x8mm.
Slide the two 68° brackets and tighten all screws firmly. Add two T-Nut with two M5x8mm in the top holes.
Fix the 90° T-Bracket on the 20x20x430mm V-Slot with three T-Nut and three M5x8mm, adjust and tighten all screws firmly. Preload the four other T-Nut with M5x8mm.
Slide the two Z axis, not need to be accurate at the moment and do not tighten the screws too much, just to keep up. Add one T-Nut on the right Z Axis for the endstop.
