Printer just stops

[philem]

Need a little help guys.

I have an Ender 3, I modelled a part, sliced it in Cura, but, when I went to print it the printer basically just printed the skirt then stopped. I resliced the part in Orca, but, this time the printer printer the rafy then stopped again, I restarted the print, but, this time it stopped again but in a differant position.
What am I missing ?

Hard to tell.
It was working before?
Cura setting changed?
Lose wire, connector?
Any error code?

I run repetier host on laptop to monitor the printer.

I run repetier host on laptop to monitor the printer.

I have run some files before but they came loose so had to stop the print.
I never changed anything in Cura, don't know enough about the programme yet.
Don't know anything about the wiring and no error code. Just that the latest prints the machine stopped in 2 differant places.

I will try another model, also will splice in another slicer as well.

What is repetier host ?

I have an ender 5 that was doing that (not stock, I upgraded control board, power supply, extruder, etc.). Randomly it would stop on long prints...
I don't know for sure what the problem was/is. But I put a fan pushing air over the the control board. I don't know if it's heat related, but it's all I could think would cause random stops on long prints.
I haven't done any super long prints since. But I haven't had the problem since.
Maybe rig up a fan temporarily and see if the problem goes away?
The Internet was of no help when I searched trying to figure the problem out.
Though @Frederick_Law would probably be able to help better. He builds these things from scratch. What do you think about my idea Fred?

Sounds like OP's stop after first layer.
No idea unless it got some error code.

It give you some control of 3D printer on computer/laptop.
It could show g-code and message from printer.
