CNC D-500 Build Instructions V1.0 http://www.ukcnc.net Please make sure you have checked the Plate Checklist and that all the parts have been received. Before proceeding with these build instructions. Unpack the ballscrews and the FK12/FF12 bearing sets. Be careful to not loose the little circlips that are packed with the FF12 bearings.
Page 2
rubber nitrate gloves to protect your hands from this thin oil penetrating your skin is advised. Slide the bearings over the end of each ballscrew. If a little bit tight then gently tap on with a tube that matches the inner race. Do not hammer the whole bearing as you could damage it.
Page 3
It is up to you when you apply grease, but can be easier as you assemble or you can do it at the end of the build. We always find it easier to place the grease into a syringe first and then squeeze some grease into the ballnut until it comes out the sides.

Note the M4 holes in the bottom of the plate, these will face downwards when assembled. Insert the M6 x 25mm screws hand tight.
Page 28
The reason we put all the screws in hand tight is so we can now easily square up the frame. Make sure the frame is on a flat even surface and then tighten off the M6 screws first on the front and back plate, making sure the other plates are nice and square to the edges of other plates.
Page 29
Get the parts shown above ready for assembly. We would recommend having the nipples of the bearing facing outwards on each rails and have supplied a plastic insert that will allow you to achieve this if needed. First bring the bearing gently to the end of the rail and offer up the insert so it lines up with the bearing.
Page 30
Next slide the bearing off the rail and onto the insert. Finally turn the bearing around and slide back on gently making sure the insert is lined up the rail.
Page 31
Bolt the rails onto both of the base sides, doing up the bolts hand tight. Get the parts shown above ready for assembly.

Page 33
Slide the arm now to the back of the machine and again with the template in place, tighten off the M4 rail bolts. Now slide the arm gradually along, tightening off all the remaining M4 screws. You will find the arm will gradually lift up above the template as you go along and the spacing should be the same along the travel of the rail.
Page 34
The frame should look like the picture above at this point in the assembly.
Page 35
Get the parts shown above ready for assembly. Turn the machine now on its side. Screw in each bolt as tight as they will go in and make sure all of them are the same depth.
Page 36
You will find that you probably need to tap each foot on with a hammer if they do not push on, as they are a very tight fit. Place the rubber end cap on to each of the feet.
Page 37
Make sure they are nice and even with each of the feet. All six of the feet fitted as shown in picture above.
Page 38
