Hello, any help would be great
Turning on the machine, it drives up to the top but then moves very slowly to the right, not going home (top left) as it should. Anyone?
Make sure you have entered the correct serial number in the software. The nano controllers do funny things if the serial number is not set correctly.
Well, we’ve used it hundreds of times. Now it’s started doing this…
Try cleaning the end stops, mine got dirty and did the same thing.
Tried that. Could this fella be the culprit? Something has gone wrong

@ian_humble from experience and a couple of them users this most likely is : cleaning the optical endstops and / or check each solder joint on the cables
Thanks, I’ll look at these things.
Is there anywhere in the UK that sells spares for these machines?
This post (work in progress) may help you. There are links to schematics to use for testing.
