So, for a while now I have had a Bit Zero V1, and I thought I’d upgrade to the V2 because now I am cutting more aluminum, and with an aluminum base and fully grounded SO3 XXL, it is sometimes difficult to electrically isolate the block of aluminum I am trying to cut.
So, I bought the V2 and installed it. Then the trouble started * dun - dun - DUNNNNN *
I took off the metal housing covering the controller board, removed the V1 wiring from the splitter board since I have the Bit Setter (V1 or SO3 version, or whatever) as well. I plugged in the V2 Bit Zero and arranged the wires back in the box so I could close it back up.
I close it up and turn on the machine and do the initialization. While it is doing it’s thing, I tap the magnetic pigtail lead to the top of the V2 and the light goes from green to red. Heh, neat. I do it again, and the machine stops moving. CM says that the machine is disconnected. Uh, weird. I power cycle my XXL and re initialize and let it do it’s thing. Put in a 1/8" bit and measure it with the Bit Setter.
Move the spindle to the corner of a fixture I have clamped to the bed to play with my new toy, and start the zero process.
It hits one side, cool.
It goes to the opposite side of the circle it is in, neat.
It goes to the middle and then moved to hit the third point in the circle and it touches the wall and. . . .stops. No disconnect, just frozen.
Okay, maybe I dorked the wiring a bit, so I open up the controller cover and rearrange things a bit, take out some wire bends and do a bit of straightening. Put the cover back on.
Start it up. Initialize. Probe bit length. Move to my zero location. Try to probe.
Disconnect on first contact. Get disconnect error on CM.
Okay, what the heck is going on.
Restart. Initialize. Touch V2 block to spindle once (Green light goes red), twice, third time - disconnect.
Restart. Initialize. Touch V2 block to pigtail once (Green light goes red), second time - disconnect.
Okay, nothing is moving. Nothing is shaking. Vibrating. This is a weird electrical issue.
Remove V2 and re-install V1 Bit Zero.
Restart. Initialize. Touch V1 block to spindle once (Green light goes red), twice, three times. . . 6 times. . . No effect other than proper indication of green light turning red.
Touch V1 block to grounded bed once (Green light goes red), twice, three times. . . 5 times. . . No effect other than proper indication of green light turning red.
So, apparently there is something different enough with the V2 Bit Zero that it is not usable on my fully grounded SO3 XXL. Anyone have any ideas?
Edit: I measured the voltage and current between my Bit Zero V1 and the bed:
4.85 VDC
4.05 mA
I get the same with the V2 Bit Zero as well.
