I tried to do some cutting tonight and ~2 hours into the job my shapeoko disconnected from the computer. I powered everything down and could smell burning electronics. Looking at the control board I found that the Z axis motor drive is melted.
I have very minimal run time on my shapeoko because i’m just too busy at work to play with it. Any idea what could have caused this to happen?
- I was cutting poplar, and looking at where everything stopped, the Z axis was only holding position not plunging up/down, since it was cutting in the X/Y axis.
- I have the ‘suckit’ dust boot attached and I think it does a very good job of keeping dust/chips at bay so I don’t think much could have got inside the control board to short things out…
- Maybe this is a heat issue? It was running in a room at ~22C which should be okay?
- I did check the movement of the Z axis and it raised and lowers down to the current cutting depth without any issue.
Open to any ideas that may point me at the source of the problem… little nervous to just buy a replacement board if the problem is just going to happen again.
