I think I'm set on:
Existing servo motors 86V 12.5A
Existing encoders (if they work) 5V 500p/rev
Power supply 1.5kW unless I can find 2kW
Antek - PS-15N77
Options:
#1 Pico systems:
EMC2
Universal PWM Servo Controller (4 axis) $250
Pico Systems Universal PWM Servo Controller
PWM Servo Amp $125 x 3
Pico Systems PWM Servo Amplifier
Parallel port ?
Spindle Digital to Analog (DAC) speed control $50
#2 Mesa:
Mesa Electronics
EMC2
5i25 PCI card $89
7i76 Step/dir daughtercard 5 axis step/dir + i/o + spindle control $119
Gecko 320 $115 x 3
#3 Mesa:
EMC2
same as above but with 7i77 analog servo interface instead of step/dir
analog drives???
#4 Dynomotion:
Dynomotion | Motion Control Boards
Dynomotion software: KMotionCNC
KFLOP $250 USB
SnapAmp1000 $400 4 brushed servos, 80V, 8A cont., 15A peak + 14 i/o
Kanalog $250 a bunch of i/o
I'm a little wary of the software because I don't know anything about it.
I like the idea of the Mesa 5i25 being a purpose built PCI card rather than a repurposed printer port.
I'd really like peoples comments on EMC vs Dynomotion and also general comments and guidance. Thank you.
