No spindle output.

[Preb1]

I need some help please.
I have been using UCCNC for about 4 years using Gerry's 2017 screenset and a UC400ETH. Not really had any problems in all that time. I have only just recently updated to the latest software and also gone back to the standard U.I. Screen set.
Anyway I had not used the machine for about a month and today I went to use it and I had the following problem. I had no output to the spindle even though the settings were set correctly. If I pressed the CW button I got no spindle relay output but the VFD showed an output. If I pressed the CCW button the spindle relay clicked but not output from the VFD.
I also had the Neon screenset loaded and even with the same settings the spindle works fine although for some reason the program will not run as the spindle keeps wanting to crash into the table, but the point being is that the spindle runs fine with the Neon screenset but not with the UCCNC screenset on the same settings. I suppose the moral of the story is I should have left it all as was as it worked fine.
I have attached a screenshot of the spindle settings if it helps.
Many thanks.
Paul
