Tonight we are going to have server maintenance. The time-frame for the maintenance is scheduled for Wed, 8/14/2013 from 9:01PM to 3:00AM PST. Our server may be down for a shorter while during these hours but we are trying to keep any downtime as short as possible.
An issue with the images that shows in the popups for G and M-codes in the editor managed to sneak in when we compiled the last version (V126.96.36.199). We are sorry about that. The fixed version (V188.8.131.52) is available on our download page.
