USB device no longer recognised


(Sarah Cotterill) #1

All works well, then for no apparent reason the machine stops. My computer says “USB devise Not recognised”.
I have tried using altenative USB ports, but the same thing, job runs fine and then, you guessed it “USB devise Not recognised”. Does anyone have any ideas?

Which version of CM are you using? If not the latest, please update — the timeout was increased in a recent version.

There are a number of suggestions which the community has put together (please note some of these are contradictory — support@carbide3d.com suggests a subset of them): https://www.shapeoko.com/wiki/index.php/Electronics#Recommendations

When trying them, limit yourself to ones which you reasonably believe will apply to your situation and which you feel comfortable doing, and understand the ramifications of — don’t buy dodgy stuff just to try (esp. no low-quality USB hubs).

Usually some combination of the inexpensive/free options works (best bet is the quality USB cable w/ ferrite beads) — if it doesn’t contact support@carbide3d.com and we’ll investigate the two pricey options — newer revision board, or USB isolator. If you’re in a hurry w/ money to burn, the latter is probably the hot ticket.
