Hi, Folks: I’ve just about got the hardware to convert a manual Sherline model 4400 lathe to CNC. The last step is to set up a box to hold the power supply, motor drive, etc. and then to interconnect the computer, motor drive, and stepper motors.
My Hardware Configuration is: Sherline model 4400 lathe with Sherline’s CNC motor kit. Hobby CNC EasyCNC 3 axis motor drive (only 2 axes will be used) Sony PCG-F430 r PCG-F480 computer The computer is set up using Linux V8 with EMC 2.3; max allowable memory on the Sony precludes using a newer version of EMC or a newer OS. Linux is Hardy Heron. Also can boot into Windows XP or Windows 98se. Hard drive is 40 gig IDE. I’m using an older version of Vector CAD as my drawing program; I assume that the spindle center is X=0; am thinking that the end of the part nearest the spindle will be Z=0. Are these a reasonable set of assumptions? Is the tool moving away from the spindle in both the X and Z directions considered positive? Does anyone have any advice on how to continue? I’m planning on making sure that I can jog the motors reliably before going any further. From there, it’ll be “cutting air” to see how the tool would be moved. I’m thinking that my first “real” part will be an N-Scale bell for a locomotive that I recently purchased. Thanks for any help you folks can provide. BTW, The maximum memory that the Sony computers support keeps me at Linux 8.x and EMC 2.3. I’ve already got one of the Sony’s running my Sherline Mill and am quite satisfied with the performance I’ve gotten. My only (reasonable to me) option is to use the HP ZV-6000 that I’ve got which has 2 gigs of memory. But that computer doesn’t have a parallel port and I’ve yet to figure out how to get the PCMCIA parallel output port card that I’ve got working under Linux. Of course, I’ll admit that I’m not pursuing the problem nearly as diligently as I’d be doing if I hadn’t acquired a few of the Sony computers. :) Jerry Jankura So many toys….
