Although the V90 is an entry-level machine, it’s decidedly not a toy. The way it functions is complicated — a platform carries the tool holder; a larger gantry moves the tool back and forth; the frame positions the gantry; and it’s all driven by a motor turning the screw interposed between two shafts. Indeed, this three-axis Cartesian robot is probably the most complex machine I’ve ever built, and I had expected it to be correspondingly difficult to assemble; however, quite the contrary — it’s easier than many common bike repairs. 7.6 Mc Tibia 8.60 Rar. A thriving community actively updates the online build guide, and all the materials were very helpful during my own build. • The bearings in your V90 are made of Oilite, a microporous metal vacuum-impregnated with lubricant. The centerless ground shafts ('rails') in your kit ship with a waxy, protective coating, that must be removed before they are installed in these bearings, otherwise the waxy material will clog the oilite pores and ruin the bearings.

Do not install the shafts in the bearings without cleaning them first! • Moisten a soft cloth with acetone and wipe down the shafts until the surface no longer feels waxy. • Be sure to clean all four rails. There are two smaller, 0.625' diameter rails for the short horizontal axis, and two larger 0.750' diameter rails for the long horizontal axis. • Choose the side of the gantry on which you want to mount the short-horizontal-axis stepper motor. Both sides have motor mounting holes, and the choice is only one of convenience. Think about clearances and cable pathways in the place you're eventually going to be using the robot.

• Insert the end of the smaller lead screw without the brass coupling through the hole in the gantry upright on which you plan to mount the motor. • Once the tip of the lead screw is between the gantry uprights, slip a bearing assembly, a nylon washer, and a shaft collar onto it, in that order.

Probotix Software for Pro-Bot. Easy to use programming with either directional buttons or with the more complex logo language that helps you design instructions to. With a little of the correct knowledge it can be done but mostly with the correct software. MakeCNC uses the Probotix V90 Fireball and. Instructions that is.

Note the correct orientation of the bearing assembly, with the narrower end closest to the gantry upright. • Carefully thread the lead screw through the anti-backlash nut in the Z-axis assembly. The anti-backlash nut ships with a small cardboard tube inside it, which will be pushed out as you thread in the lead screw. Haunted Hotel 5: Eclipse Collector`s Edition. • NOTE: Do not attempt to remove the cardboard tube in any other way.

Likewise, do not remove the lead screw from the anti-backlash nut once it is threaded through. Without either the tube or the lead screw in place inside the anti-backlash nut, it will fall apart, and can be quite tricky to get back together. See this document for more info.

• Once the lead screw is through the anti-backlash nut, slip a shaft collar, a nylon washer, and the other bearing assembly onto its exposed end. Push the lead screw in, sliding the Z-axis assembly with it, until the bearing assembly is secure in the far gantry upright. • Adjust the lead screw such that about 3/4' of the brass coupling is exposed outside the gantry. Position the shaft collars close up against the washers and bearings at each end of the lead screw, and use a 7/64' Allen wrench to tighten them down. • The lower drive nut is a second anti-backlash nut that comes pre-installed in a bracket with two mounting holes, like the blue one shown here. To install it, you will need two machine screws, six flat washers, and two matching hex nuts. • Pass the two machine screws through the mounting holes in the gantry floor, from the top down.

• Slip two flat washers over each exposed screw end. These serve as spacers between the gantry floor and the lower drive nut assembly, and can be removed (or supplemented) later, if necessary, to adjust its height. • Slip the lower drive nut assembly over the exposed screw ends and doubled flat washers.
