STEP 203

STEP 203: Both rails are now in place.

STEP 204

STEP 204: Now grab the motor side of the base. Pay attention to where we are pointing in the picture here. We are pointing out the holes along the the edge of the plates. This is INCORRECT. You need to make sure that the holes on the motor end plate are facing down at the table and the holes on the support plates are facing up away from the table.

STEP 205

STEP 205: We have corrected the orientation of the holes here in this picture. This is how you should have yours layed out.

STEP 206

STEP 206: Go ahead and align the lead screw end with the bearing.

STEP 207

STEP 207: We need two M6x15 machine screws (P-19) with two M6 washers (P-20). Thread the screws with washers into the guide rails as shown.

STEP 228: Start with ten M3 wood screws (no washers). Drop them into place aligning with the sliding support underneath.

STEP 229

STEP 229: Just get them started with your screwdriver about half way down. Do not tighten yet. Check the lead screw for binding as you go.

STEP 230

STEP 230: One side has all screws started.

STEP 231

STEP 231: Now, lets begin tightening one screw at a time. You may want to work back and fourth in a criss-cross pattern to help evenly tighten down the work table. Continuously work the lead screw back and fourth while tightening in order to prevent binding.

STEP 232

STEP 232: Do the same for the other side with 10 more M3 screws.

STEP 233

STEP 233: Now we will ad the lead screw end holding nut (P-07)

STEP 242: Go ahead and flip the base back over.

STEP 243

STEP 243: Let's get the Z axis together now. You will need parts 4/5, 6/7, 8, 9, shot remaining lead screw and guide rails. Lay out all of theparts just as shown here. Pay attention to where we are pointing (the holes along the edges of the plates. The top and bottom parts should have edge holes facing down and the sliding supports edgeholes should be pointing up.

STEP 244

STEP 244: Another shot of the edge hole orientation.

STEP 245

STEP 245: We will start off by attaching the lead screw anti-backlash nut to #4/5.You will need two M4x20 machine screws (P-15), two M4 washers (P-16), two M4 lock washers (P-17), and two M4 nuts (P-18).

STEP 246

STEP 246: Add lock washer then flat washer to the M4 screws, then add one of the screws to the end of your allen wrench.

STEP 247

STEP 247: Insert the screw through the larger hole in part #4 and into the smaller hole in part #5.

STEP 248

STEP 248: Do the same with the other screw.

STEP 249

STEP 249: Now slide in the lead screw and align the holes of the anti-backlash nut with the screws. Add the nuts to bothscrews and tighten down.

STEP 250

STEP 250: Lead screw attached.

STEP 251

STEP 251: Now wipe down your guide rails clean.

STEP 252

STEP 252: Slide the guide rails carefully into the sliding supports as shown here. Be careful not to damge the linnear bearings.

STEP 253

STEP 253: Notice the orientation of the edge holes on the sliding supports. They are both facing up. Also the anti-backlash nut is in the middle of both sliding supports.

STEP 254

STEP 254: Next attach the motor end support by sliding the lead screw into the bearing. Notice the edge hole orientations here. We will be attaching the guide rails with two M6x15 machine screws and two M6 washers.

STEP 255

STEP 255: Align the guide rails and thread in the M6 screws.

STEP 256

STEP 256: Tighten them both down.

STEP 257

STEP 257: Now let's attach the bottom side. Notice again the orientation of the edge holes. We will need two more M6x15 machine screws and two M6 washers.

STEP 258

STEP 258: Slide the lead screw end into the bearing block.

STEP 259

STEP 259: Align the guide rails with their holes.

STEP 260

STEP 260: If ever the lead screw does not easily slide into the bearing, it may help to lightly sand the ege to remove any possible sharp edge. Just twist a small piece of sandpaper around the end. It should not take much sanding if any to get the lead screw to go into the bearing.

STEP 261

STEP 261: Lead screw is now fully seated against the bearing.

STEP 262

STEP 262: Thread in the M6x15 screws with washers.Tighten them down.

STEP 263

STEP 263: Be sure the lead screw rotates smoothly.

STEP 264

STEP 264: Now lets add the tool base Part #16. You will also need 12 of the M3 wood screws with washers.

STEP 265

STEP 265: Align the #16 properly and putting wood screws in place.

STEP 266

STEP 266: Start tightening up the wood screws.

STEP 267

STEP 267: Make sure check the leadscrew movement while tightening up each wood screw.

STEP 268

STEP 268: After all wood screws installed, also check the leadscrew movement, if everything aligned properly, you shouldn't feel much friction.

STEP 269

STEP 269: Now we will put end holding nuts, it has two set screws.

STEP 270

STEP 270: Before tightening up the set screw, push the lead screw against the end bearing.

STEP 271

STEP 271: Check the leadscrew movement, if there is any excessive friction observed, loosen up some screws and make alignment adjustment now.

STEP 272

STEP 272: Now the Z axis completed.

STEP 273

STEP 273: We will put the Z assembly onto gantry(X Axis) assembly.

STEP 274

STEP 274: You will need M3 wood screws to install Z assembly onto gantry assembly.

STEP 275

STEP 275: Start with wood screws on top of the #21.

STEP 276

STEP 276: Align Z assembly properly.

STEP 277

STEP 277: At this point, you install all wood screws without tighten them up. Prepare for the final alignment adjustment.

STEP 278

STEP 278: Install wood screws at the bottom of #21.

STEP 279

STEP 279: Now put wood screws on one side.

STEP 280

STEP 280: Wood screws on other side.

STEP 281

STEP 281: After all wood screws installed, tighten them up slowly, make sure everything aligned properly.

STEP 282

STEP 282: Now you have Z axis installed on gantry assembly.

STEP 283

STEP 283: Now you will need to put gantry assembly (with Z axis installed onto the base, with M6 machine screws, nuts and washers.

STEP 284

STEP 284: Put M6 washers on both sides of the board.

STEP 285

STEP 285: Sometimes, the screw hole is pretty tight, so you will need to screw them into the board.

STEP 286

STEP 286: Don't tighten up the screws, only after all screws installed, and everything aligned properly, then tighten all of them up.

STEP 287

STEP 287: If the inside nut is hard to reach, move the table back and forth to make some room.

STEP 288

STEP 288: Finally, we will install all stepper motors with M4 machine screws and nuts.

STEP 289

STEP 289: Motor installed on Z Axis

STEP 290

STEP 290: Motor installed on X Axis (Gantry)
