Disclaimer I have opened a support ticket (late last night), but for future searches and discussion I am making a topic here. I like knowing why something isnt working and the steps involved to verify it etc. so sharing time. If anyone has any insight or suggestions feel free to let me know. The last couple years the vfd spindle have been great and I really dont want to swap back to a router if I can avoid it.
Last night got a rush order from a friend. Clamped down the stock set zero, probed the bit etc. Rapidly moving towards the stock… huh its not spinning, STOP.
Weird this was working a couple days ago.
Troubleshooting steps I took.
Checked all cables, power connection, buttons, everything seems correct. I mean nothings changed in the last few days.
Searching the forums found a few topics but no resolution. Some mentioning a potential issue with Spinderella 1.1 boards. Dim red light etc. As far as I remember the light looks right, maybe its slightly dimmer, idk.
One post suggested measuring the voltage across the White and Black wires while feeding it MDI commands (or spindle warmup routine)
Voltage meter at the end of the cable (vfd end)
Motion v640: spindle warm up
8000 rpm 2.73v
12000 2.99v
18000 2.27v
24000 0v ?
Wasn’t expecting the drop in voltage, Run spindle warmup again?
8000 2.73v
12000 2.98-2.99v
18000 2.27-2.28v
24000 0.01-0.00v
Voltage meter at the shapeoko board end (no cable)
Same results/values
Holding jog on the vfd, vfd ramps up to 1200 and spindle spins. However after this round of voltage recording I’ve noticed the Red light does not light up on the vfd anymore. Tried power cycle, button presses, nothing. Unplugged everything, took the geriatric dog for a slow walk around the block. Plugged everything back in the red ring light is lit up again, but I’m starting to think it is dimmer than normal. However still no response from MDI commands to spindle spinning.
