Maybe not the place to post -- but is a website issue: Ref the G540
PDF on Page 3 of the G540 -- shows the E-Stop wired to Connector at 10 and 12 -- but previous page shows E-Stop at Connector 6 and 12 (12 being Earth). Which is correct? I expect page 2 of the pdf as it also shows that Connector 10 is an Output ( to LPT 16).
Great site - great work on the G540. Ahh, but as you know that the devil is in the details. (or did I miss this elsewhere?)
