Yesterday I updated Easel Local to Version 0.3.3 but could not connect X-Carve. When trying to access machine Easel kept asking me to download new driver even though I had done this.
Reverted to version 0.3.2. and X-Carve was recognised by Easel and I was able to use as normal.
Possibly a problem with 0.3.3 and Mac. I am using Sierra Version.10.12.3
