it would seem that my thread with the cnc startup pics has gone by the boards. so, here we go again! got the bench made and ready to go a while back. i'll have to modify it a bit to fit the 1.8 meter rails. then the fun began. there was a long box, and a flat box. seems the flat box had all of the upgrade parts, and the long box had all of the regular parts, along with the longer rails. tuesday i started putting the v wheels and pulleys together (sorry, no pics there), and wednesday i put together the four carriages. more pics to follow when more is done.

got a bit more done the last couple of days. got the spindle carriage assembly put together, and my brother did the tapping of the screw holes in the ends of the aluminium extrusions. soon it will be the testing out of the electronics.

darren, it uses a belt drive for the carriage, and a threaded rod to drive the z axis.

ok, here we go! added the motors to the sides of the gantry, and the back of the z axis assembly. the motors on the ends of the gantry control the back and forth on the y axis (for my build, the long way), and the one on the back of the z axis assembly controls the back and forth along the short way. now on to the assembly of the y axis frames, and then we go on hold until i get the 3/4 inch mdf to replace the standard base.

got as far as i did, when i found out there was a bit of miscommunication, and i didn't get the 1800 mm maker slides, but got the 1500 mm extrusions (if you need any extrusion bill, let me know :D). then i got myself a bit more active today, and decided to go forth with the stock maker slides (500 mm). long story short, all the parts fit, and now i just have to wait for the longer maker slides. what i'm planning on doing with them when they get here, is to cut them a bit longer than the 48 inches of the bench, then finish off the machine when it is on the bench (much better than on the floor). i've picked up the mid-rail supports, and ordered a new bandsaw blade from grizzly to cut the maker slides to length. now my wife :blah: can see what the machine looks like fully assembled.
