On a Downhill Slide

There was a time when the Tevo worked almost without flaw. It had entered the "Appliance Mode" - send a job to it, forget about it and be notified to collect the result some later time when completed.

These last few weeks have entered into a different mode of operation. The WTF mode....

Printer doing a bit of AI abstract art of it's own...

Printer saying "I don't care what sort of Z-Axis smoothing devices you install, I'm doing my own thing"

Me: "I need to go out but have just started this print job".

Me: "I'm sure I won't have a 1st layer adhesion problem as it's been good the last few days...

On my return: "Ah, I see, 1st layer adhesion excellent".

Me: "Was not factoring in that black hole sized gravitational anomaly suddenly winking in and out of existence from the left".

The truth of the matter is that in all the years I've had this Tevo, the only lubrication it has every received are from my tears of despair as a long running job failed in an unexpected manner...

Might be time to lube up as I cannot explain lost Y-Axis steps to such a degree.
