i have read this thread on the topic ( GRBL Error: Serial Port: ResourceError )
and i have followed the suggestions from @WillAdams
- deinstall / reinstall CM
- restart and clear out PRAM
3. tried the usb cable that came with machine and a different one
4. tried to run it using my PC laptop - different error - “Cutter did not respond”
I’ve also unplugged the 611 to rule out power / grounding issue.
this is my 2nd time trying to use the Shapeoko 3. it ran the “Hello World” fine (apart from the slight drop off in the middle).
my mac laptop does not connect, running 10.10.5 screen shots below are from the three error messages i get when trying to connect. the other image shows the systems prefs - my mac sees the S3.
I was really hoping to get some work done with the S3 this weekend. any help would be appreciated.
