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?
Since then I have decided that even if the card slot problem is resolved it is a bit finiky in use so :-
Have connected the printer direct to a PC using a USB cable (the PC is running Repetier-Host)
now it will print for four or five times the way it was (even printing the 'raft' and a few layers ) then just stops.
The 'log' on Repetier states (something like) " not the last line "
Again stumped as to what is the cause .
All i want is the unit to print I shall worry about quality later,
