Novaturn NS

I bought a Novaturn NS recently and have so far not been able to get it running.
I tagged onto another thread about a similar issue, so in a last ditch effort to find some answers I thought it worth starting a new thread about it, in the hope it catches someone’s eye.

These are the things I have done and the results, thanks to help from CNC Guru Martin.

I have the original PC and software with license.
Don't have the upgrade software on the PC nor do I have the original discs.
VR Turn is Version 1.39.0.0.

Made a new 9 pin- 9 pin cable from PC to control card directly from this link
https://www.denfordata.com/bb/viewtopic.php?t=231

3 fuses were removed and checked as good.

When I start the machine and software I get this:
Control board 7 segment green display shows an “E” flashing
Hit the Machine Control button and a dialogue pops up, followed by a "Downloading Program" box with "Erasing Flash" progress bar.
This produces an "8" on the display
Hit the "Home" button on the machine control dialogue and get a solid "h"
The x/z DRO's then start to climb to ridiculous figures (3500mm)
And that's about it. Software locks up.
Freezes after that.

If anyone can shed any light on either what the problem might be, or a way to diagnose it I would be very grateful indeed.

It sounds like you have an issue homing which may be as simple as a axis drive fuse.

Can you post a picture of serial plate & the electrical cabinet.
