Hello everyone on the emc users list! My name is Jim and I hope we'll be
getting to know each other pretty well. I'm a machinist, living in Ohio.
Straight out of high school (vocational school, 2 years of 'Precision
Machining Technologies') I'm working part time at a local machine shop
running 3 and 4 axis vertical mills or sometimes a lathe. If I ever go on
to college, I think I'll major in business management or electrical
engineering. I've been into tinkerin with electronics since i was around 5,
mostly involved ripping toys apart and rigging speakers together, until I
got a radioshack experamenting kit for Christmas when i was 6, the cardboard
ones with spring terminals, and I've since gotten into radio (CB, scanners)
and computers and overclocking, and dabbled a tiny bit in microcontrollers.
I recently purchased (actually still have to get the damn thing moved!) an
older Hitachi Seiki VM-40 VMC, which has some damage and the computer is
going senile as i like to put it. As you've probably already figured out,
this is where EMC is coming into the picture. I am planning on replacing
the control with a P4 2.6 rig, 1 gig ECC ram PC with a mesa 5i20 card. I
have seen discussion of using a filtered PWM signal to drive a servo amp,
and was wondering how accurate this would be, and if it was a viable option
to buying a servo amp interface. If not that, could a DAC be used? I'm
still cloudy on how the servo amp works with the signaling and stuff, but
trying to learn none the less. The servos are Sanyo Denki BL Super, 1.3 kw
for x and y and 2.8 for Z, spindle is a mitsubishi freqrol VFD on a 7.5 hp
6000 rpm motor. after I get those working, I'd like to get the tool changer
fixed, one of the problems with the machine, the Y axis either encoder or
amp malfunctioned, and ran the spindle into the tool changer arm and bent it
up. and I need to figure out if its the encoder or amp, but I should be
able to hook the encoder's a and b to a parallel port and find out right?
and use the parport to hook up the handle, its a 100 count encoder in a
little box with XYZ 1 10 100 buttons.
I plan on starting individual threads when I get things together (money for
a mesa card, getting the machine moved...) and run into problems. really
looking forward to using emc, and glad I found it before I went with mach.
