I live ok on it, but, it's the unexpected thing that really throws a wrench into things. > >> I also have the spindle apart, to put new bearings in, and to >> redesign the convoluted way of moving it.

The pinion is a 14 tooth module 2 spline, which barely meshes with the tips of the teeth on the rack. when I get my check next week, I'm going to order 2 - 15 tooth, and 2 - 16 tooth gear sets, to see which set fits better. Then I will machine a new shaft to hold them. Later on, I will machine a new pinion to fit. As for the leadscrews, I may be able to make some TR24x3 nuts, and lap them until they fit the leadscrew. Not optimal, but cheaper than ballscrews. The spindle has a MT3 taper, but I've been considering re-machining it to accept either CAT30 holders, or something like Kwik Switch, or SPI. Then, I will have the ability to build a tool changer later on. By then, I might actually get some code out of Heeks, that gives me a part that somewhat resembles what I've drawn. >>> There was a time when I dreamed in 6809 assembly.

In high school, circa 1983, I cut my teeth on a TRS-80 Model III. Learned BASIC on that machine. 2 - 360K 5-1/4" floppies, and a serial connection to a master computer, witch had a whopping 5MB hard drive. I played around with the CoCo's, but by then, I was in College, and using early IBM PC's. After College, I was a Vacuum, and Transportation tech. maintaining cryopumps, targets, and rail systems, on sputtering machines that made hard drive platters... Before it was all moved to Malaysia. Then, I became a robotics tech for a large multi-national corporation, mainly working with PLC's (AB, and Modicon), industrial computers, and custom computers running QNX. There, I used OS/2 with Win3.1 on the desktop. The other company standardized on Mac SE. I used my own version of Linux for a couple of years, and it ran really fast, with uptimes measured in months. But, it became a full time job just keeping up with all of the security issues, so I switched back to Red Hat, and then Fedora. Now I'm running Ubuntu 11.10, but, I think that this is my last version of Ubuntu for full-time use. My old laptop, with 10.04, could go for 30, or more days between reboots, and I only rebooted for kernel updates. My new one, ran fine on 10.04, but some of the hardware was too new for it. 11.10 crashes daily, and things changed so much between the two versions, that I'm throughly pissed off with it, even after kicking Unity to the curb. I'm not sure whether to go back to Fedora, or find something else. Something with low dependency hell. OH, and I never really liked Emacs, I use Vim, and I keep a term window open full time on my computer. For me, it's easier to type something, than click through multiple menu's to find something. -- -Mark Ne M'oubliez ---Family Motto Hope for the best, plan for the worst ---Personal Motto ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
