I have a Nomad 883 that I haven’t used for years and I’m trying to get up and running again. I’m using the V3 software version to avoid the error (GRB: Versions prior to 1.1 are not supported). I’m running this on my 2019 Mac book pro- which is 64 bit. I can load the job, zero out, start the job, it measures the tool and once it is about to start I get “GRBL Error: Serial Port: Resource Error”. I read on a forum to reset my system management chip and that didn’t help. In the carbide community all the links people list for additional information just go back to the website and not specific information so I’m having trouble figuring out what to do next. Anyone running an older Nomad that can help me with this? 
. Thank you!
One thing to consider would be reflashing to Grbl 1.1:

that would let you use the current version.
I’ll try that! Thank you!
I’ve been googling and I don’t know where the z axis limit switch is and this is part of the update- do you know where I might be able to find a picture of where this is?
There are some photos at:
thank you! I’ve been holding the one oriented down for about 5 mins and there is no progress on the “updating firmware”- the instructions say it should take about 30 secs. I quit the update, closed it, shut the nomad down and tried again and I’m having the same issue. Any suggestions?
Do you have a Nomad 883 (Classic) or a Nomad 883 Pro?
Check in w/ the folks at support@carbide3d.com — they’ll need photos of your machine.
I have the Nomad 883 pro
