Makerbot 3D打印机装配教程 4.Y-Stage Assembly(Y轴平台装配)

弘毅

Building the Y Stage should take approximately 1 hour. At the end, you’ll have an assembled XY Stage ready to be inserted into a Thing-O-Matic.

Parts List

These are the parts you’ll need to assemble the Y stage. All laser-cut parts should have their names etched onto them. Find and put aside these parts:

• Laser-cut Stage Parts
  
  • Y Front
  • Y Back
  • Y Top
  • Y Bottom
  • Y Left Side
  • Y Right Side
  • Y Left Top Cap
  • Y Right Top Cap
  • Y Drive Rib
  • Y Idler Rib Assembly
  • Y Clamps
    
• Four (4) M3x10 socket cap bolts
• Four (4) M3x16 Low-profile socket cap bolts (they are silver-colored)
• Thirty-one (31) M3x16 socket cap bolts
• Thirty-five (35) M3 nuts
• Three (3) M4x25 socket cap bolts
• One (1) M4x50 socket cap bolt
• Fourteen (14) M4 nuts
• Two (2) 3/8″ self-aligning bearings
• Three (3) 624 bearings
• One (1) stepper motor
• One (1) stepper motor pulley
• One (1) cork gasket (not shown)
• One (1) idler pulley
• 272-tooth continuous timing belt (Early May 2011 and on may be a 267-tooth belt)
• One (1) mechanical endstop switch (not shown)
• Two (2) 1/8″ spacers (not shown)
  

Build itWhat you should be starting with

We should have prepared these parts in our “Prep” phase:

Attach Y Belt to Drive Rib

parts needed:

• 272-tooth (or 267-tooth) continuous timing belt
• 2 Y Clamps
• Drive Rib
• 4  M3x16 bolts
• 4 M3x16 nuts
  

Take the 272-tooth (or 267-tooth) continuous timing belt and use the two clamps to secure it to the drive rib. Make sure it’s nice and tight as clearance with the Y rods is very close.

Attach Top to Idler Rib Assembly

parts needed:

• Y Top
• Idler Rib (assembled in prep stage)
• 1 M3x16 bolt
• 1 M3x16 nuts
  

Attach Top to Ribs

parts needed:

• Y Top
• Y Driver Rib
• 1 M3x16 bolt
• 1 M3x16 nuts
  

The holes will guide you, and the 624 bearings on the Idler Rib should be towards the left (the side with the elongated motor mount holes, behind the empty bearing hole).

Attach Motor to Top

parts needed:

• Y-Stage
• Cork Gasket
• 4 M3x10  bolts
  

Attach the motor to the top using four M3x10 bolts, keeping the bolts loose. Push it all the way against the bolts that secure the 624 bearings to the Idler Rib but do not tighten down firmly. (You will be adjusting the placement of the X-axis stepper motor after you determine how much tautness/slack is in your belt.)

Attach Rod Caps to the Left Side

parts needed:

• Y Left
• 2 Rod Caps (the little curved triangles with two holes in them)
• 4 low-profile M3x16 bolts (the heads are shorter than those of the standard M3x16 bolts; they are silver-colored)
• 2 M3x16 nuts
  

From outside-to-in: it should be M3 bolts + rod caps + left side + nut. Tighten the bottom screws down.

Modify Rod Caps

Remove the top bolts and turn the rod caps down to reveal the holes for the rods.

Sand Rod Caps

Remove the top of each set of screws and rotate rod cap down. You will sand the rod caps, this will make adjusting the bot later easier—You’ll be able to remove the rods easily.

You need the notch so that you can remove a rod when you need to tighten your belt. The picture below shows why you cannot tighten the belt with the rods in place

Add front

parts needed:

• Y Body
• Y Front
• 4 M3x16 bolts
• 4 M3x16 nuts
  

Pay attention to the belt.

Add Back

parts needed:

• Y Body
• Y Back
• 4 M3x16 bolts
• 4 M3x16 nuts
  

Pay attention to the belt.

Attach Left Side to the Body

parts needed:

• Y Left
• Y Body
• 3 M3x16mm bolts
• 3 M3x16mm nuts
  

With the text on the outside, attach the left side to the Y stage body. Make sure the rod caps are facing out. Double check that “Left” has low-profile socket cap bolts.

Attach Rod Caps to the Right Side

Using four M3x16mm bolts and four nuts, secure the other two rod caps to the right side.

Attach Right Side to the Body

parts needed:

• Y Body
• Y Right
• 3 M3x16mm bolts
• 3 M3x16mm nuts
  

Attach X Min Switch (End Stop) to Right Top Cap

parts needed:

• Right Top
• 2 1/8″ spacers
• 1 M3x16mm bolt
• 1 M3x12mm bolt
• 2 M3x16mm nuts
  

Attach Right Top Cap, Idler Bolt, and Idler Pulley

The idler pulley rides an M4x50 bolt. Thread the M4x50 bolt through the top cap, then through the idler pulley with the belt looped around it. Place the bolt through the hole and install the top cap. The bolt gets two nuts on the bottom underneath after you get it all in place. Make sure the belt is around both pulleys before you move on to the next step.

Don’t tighten it down too hard or you’ll crack the wood.

Right Top Cap

Secure the Right Top Cap with two M3x16 bolts. The T-slot under the endstop will be empty.

Tighten

Lock the nuts against each other to prevent it from vibrating off.

Insert 1 rod into the Y stage

Inserting the rod and attaching the X stage has to happen at the same time. These rods are the shortest rods in the kit.

Adjust Belt.

Pull the motor towards the left to tighten belt. Tighten screws.

Second Rod

Add second rod, turn rod caps to cover holes and tighten the screws.

Attach Left End Cap

This piece goes over the motor. Tighten it down.

Complete Left Side

Attach Bottom

parts needed:

• Y Body
• Y Bottom
• 5 M3x16mm bolts
• 5 M3x16mm nuts
  

If you’ve tightened all the bolts down already, this may be a bit hard to get on. Loosen everything a bit and it will slide right on.

You can use a magnet to hold the nut in place:

Zip-Tie Stepper Motor Tail

This will help make sure that the wires stay out of the way and don’t get caught under the platform while it’s moving.

Tighten All Bolts

Ensure that all the bolts are tight.

Congratulations! You’ve completed the XY Stage
