Ender3 won't print. SD (TF) card issue?

[Rudolph Hucker]

I have just built an Ender3 PRO but I can't get it to print (shall worry about altering settings to up the quality once I can get it to print at all).

My SD card (TF) socket seems VERY tempremental .

Sometimes it registers as card missing (TF CARD ... NO) despite on a previous screen (info) it 'states' 'card inserted'

Sometimes it recognises the card but on entering the card contents it appears empty

Once in a blue moon it records the card as inserted and the card has stuff on it and it will print (maybe two or three layers) but just stop , nothing seems to work except turning the entire unit off.
This final behaviour appears to be a misbehaving SD (TF) card so I tried various other cards I had lying about . All seem to exhibit the same behaviour .
Sort of thing I mean https://www.youtube.com/watch?v=IYsxg7Wspvc Only using different cards solve nothing.


Have (sort of ) now decided that the SD (TF) card slot itself is somehow FUBAR and it is not the individual cards .
Had the motherboard cover off but there is nothing obviously wrong .

New motherboard time?
Do Creality tend to just send a new board (well within warranty)?
Is changing MB easy?
Can I just remove 'hot-snotted' connectors?

Or is this a known easily fixable problem and I am overthinking it?

My preferred fix would be to print via octoprint on a rasberry pi or something. Prints via USB, gives you a web interface for control, tons of addons and options to play with. SD cards can often be temperamental in these printers.
