WHat do you mean by 'behind the reader' ????
HI. I have a leblond Makino 64 at work, and I'm bound and determined to get it working in DNC mode so my boss can sleep at night. I can't seem to convince it to work in DNC mode, although i can send...
got a picture?
it says dc servo motor 24v 1.15A Japan Servo co. ltd
Do you think I could fetch much for them on ebay? From what i have read in these forums, steppers are more economical to experiment with anyhow. I want to build CNC to learn, not to go into mass...
What other drives might be compatible with servos of this size?
so assuming I can find drives for this pair of servo motors, what size of machine are they capable of moving reliably?
Anything I can do with just a simple multimeter to test it?
I shorted the phases together and it made it really chunky to turn the shaft. i would think that's a good sign, right?
they have the motor and encoder connectors attached.
I am just wondering if there's anything I can do with a multimeter to see if they are garbage or viable. to see if its worth going out and...
I came across 2 Allen Bradley servo motors that were discarded at work for some reason (likely decommisioned equipment).
Is there a way I can tell if they are useable?
they are like this one:...
That sure is pretty.
I can't seem to run the .avi file here for some reason.. I'll have to come over and see it in action for myself.... :)
it doesn't look like you started with a drill press anymore.. looks like a very good design. Boxy like a volvo, but strong as a horse.. :) :stickpoke
I should pop by again sometime and watch it...
got pics of the (former) Delta?

Does anybody know what the difference between a stepper/indexer drive and just a plain old stepper dirve?
I have been looking at the selection of parker compumotor drives available on eBay, and by...
sheck out the lathe CNC ZONE member 'Stevie' is making.. it's awesome.. I saw it running last night... he has a thread in here somewhere. he has really documented it well, and it will be very...
having second thoughts about the whole PCB via EDM sinker idea.
The reason being that since the traces are usually isolated islands of copper, they may not be able to sustain the electrical...
To answer a question posed in this thread earlier, EDM could be used for 'burning' PCBs (printed circuit boards), using the EDM sinker method, in which a negative of the board is milled into the face...
I got the same eror message when looking for the schematic.
I am very interested though..I checked the rest of the gertrtonic site, but my german is non-existent, and didn't know what to look for....
Who has an open source servo drive design i can use to try it out?
I, too am a Wind gen freak, although I will be starting and finishing my cnc project before playing around with magnets.. I had also the idea of milling out molds for composite blades in sections....
Are ther open-source servo drives that are capable of pushing these large servo motors? I have seen plenty of diy Stepper drives on this site, but servo drives of this caliber seem scant. Does nobody...
where did you buy the motors?
the shaft spins freely as before.
so I guess it IS a servo..
what kind of drive would i need for it? i have the pcb from the copier that the servo was connected to, but there were a few different...
Really? cool!
I'll try it.
Thanks for the tip..
i nabbed one of these from an old photocopier. Only problem is I can't find any info about it
the label says dc servo motor Japan Servo CO. LTD

That is some nice work Steve. i have been watching your progress. Sorry I couldn't get over there last weekend.. Looks like this one is a washout too.. Where are you working now? (PM me if you don't...
