Does anybody happen to have a set of gecko 320's hooked up thru cnc4pc's multifunction board (c11) I've been have a little problem getting things hooked up right for over a week, and I'm getting a little frustrated.
It seems no matter what I do, I end up with voltages that are all over the place. The multifunction board requires 3 power inputs. 5v from the computer, another 5v, and a 12v. Well, with the power supply from cnc4pc, and the 5v from my computer, my outputs are between 3-8v, as Mariss pointed out, this is way to high for a 0-5v input on the gecko.
So, if I skip the pc power supply, and tap into the 5v from the cnc4pc power supply, I can get my x axis to work. But my voltages are still wrong. the ERR/RES is now up to 8v.
What I would really appreciate, is a wiring diagram that shows everything, using this exact setup. Where, if someone was using this already, it would be quite simple.
here is what I have.
gecko 320
pin 1 = ground on 36v ps
pin 2 = 36v
pin 3 = one side of motor
pin 4 = other side of motor
pin 5 = dpdt to enc- and enc+
pin 6 = dpdt to err, and encoder ground
pin 7 = dpdt to err, and encoder power
pin 8 = ch A. encoder
pin 9 = ch B. encoder
pin 10 = pin 2 on multifunction board
pin 11 = pin 3 on multifunction board
pin 12 = 5v pc power (unless conected to cnc4pc PS like mentioned earlier)
Multifunction cnc board C11 rel 1.1
jumper set to 2-3 to enable safety charge pump thru pin 17 on mach3
output side
pin 2 = pin 10 on gecko
pin 3 = pin 11 on gecko
power/relay side (with output port for DB25)
5v power = 5v power from cnc4pc PS
gnd = 5v ground
gnd = 12v ground (redundant I know, but I'm trying, and have tried it both ways)
12v power = 12v power from cnc4pc PS
input side
PC power gnd = pc case ground
pc power 5v = pc power 5v from power supply (or from cnc4pc's ps which seems to be a step in the right direction)
I'm trying to keep it simple to start with, and get moving in the right direction, but it's not been easy. I could really use some help on this.
