Queasy Greebles 1. 16x10” A3. A brief segue from the spirals. #Art you can buy, designed by me and drawn by my robot.

Each day I do a plotter build step I have to do it twice. Once to prove I have all the parts and it goes together right. Then I disassemble it and pose the parts for camera. Then assemble for camera piece by piece. And. One the plotter is assembled and working I get to take it apart yet again. To accurately inventory the parts. I’m just saying this is a lot of screwing around.

Projection 5. Last one. Ballpoint 10x8” A4 #Art you can buy, designed by me and drawn by my robot.

One of the design goals for the machine was to standardize on bolt sizes and lengths to make is easier to shop for. All the axle bolts are the same, 30mm. Every other bolt is 8, 12, 16 or 20 mm in length.

Assemble the tensioner, idler pulley and printed axle as before. Screw on the tension nut and pop the result it into the tensioner housing.

Next time we’ll square, size and align the frame and rail, and add the y axis belts. Monday, maybe!

Use the Allen wrench to get the 5x12mm bolt in place in the centre hole of the tensioner housing. Fasten it to The end of the pen rail, so the slots in the housing are on the side of the rail, and the nubs slide into the extrusion on the top/bottom.

The belt/roller mount is the same as yesterday, mirror reversed. Assemble as before and add to left side of pen rail a few cm from the end. Exact position to be determined later. The rollers should be on the bottom, as on the right side of the rail.
