    How accurate is a metal shaper?

    Hello people.
    The nex week a friend of mine will let my use a big and good metal shaper on the workshop to make the parts of my diy cnc small lathe.
    I never used this machine and never saw the...

    Al_The_Man do you suggest using the called "Dimmer" (TRiac) to make PWM on a AC motor from Mach3?
    I was in the knowledge that SSR was to make the same job than Triacs, but better...
    May be im wrong.

    Tank you all for your answers.
    I googled the dam thing (That was the first thing i did) and IT NOT EXIST ON THE WEB.

  10. solid state relay to control lathe motor...anithing alse?

    hello people.
    Last weekend, working on one of my many many projects (a home made cnc lathe) i found a solid state relay on a photocopier machine, rated to 240 volts and 16 amps max. The control side...

    This particular board have a PNP transistor. Not NPN.
    On the 24 volt connector it is a rectifier diode.
    both, the rectifier and the PNP transistor end up at going to motor power mosfets

    Hey Absat sorry for the inconvenience, but using reverse engineering on the board i found 1 PNP transistor (2SB1031) and for the datasheet should be negative voltage.

  13. should a driver board need negative voltaje???

    Hey people.
    There is something rolling around in my head since a few days now, because making a job of reverse engineering on a Ricoh stepper driver pcb, and found that:

    Hello people.
    Just a few hours ago i managed to build a lovely power supply for my cnc project (A diy scara robot) using 2 old AT power supplys from computers.
    The objective was to have 24 volts...

  16. From what photocopier machine is this stepper? (5 phase, vexta)

    Hello people.
    I have four of this motors + driver board (Main IC is Sanken SI7501)

    Vexta A4208-9215K

    Specs are:
    DC 2 amp
    0.5 Ohm

    Thank for the answer jschmitt.
    The driver is already set to max 2 amps : There are 2-1 Ohm resistors, set in parallel, so they give 0.5 Ohm.
    In the SI7502 Schematic it suggest this value for 2 amp...

    So, anyone?
    Maybe the questions are not clear enough:

    1. I should guess that "dc 2A" means "Direct current 2 amperes"; But it talk about the current for each phase? or the total amount?
    2. What...

  20. power supply to choose for 5 phase steppers??

    Hello people.
    I have 4 savaged 5 phase motors.
    They are all the same, labeled Vexta A4208-9215K
    Specs are DC 2 amp, 0.5 Ohm

    I tend to guess they are 2 amps per phase.
    2 amp per phase x 5...

    Thanks for the answer dude. Fast and clear.
    Sadly, i want to think it runs like i want (Meaning like a suitable servo for CNC use), but im starting to believe that it doesn't.

  24. could a 3 phase servo run clockwise only???

    Hello people.
    The last month i got a nice 3 phase brushless servo motor branded Kokusan Denki from a photocopier machine.

    hey people.
    I have 4 stk6712bmk3 removed from a ricoh sorter-stapler from copier machine FT6655. Great stuff but not working at all.
    Some one have made the circuit on eagle?
