extrusion stopping after 3-4 hours

[PaulGri 0]

So I have 2 ender 5 plus printers, been printing now for around 4 years, so im not exactly a newbie when it comes to printing however this problem is making me feel like one.

2 printers , same STL files, same cura setup everything.

One printer just will not print successfully , I have changed everything , extruder , hotends , nozzles, the lot. Every print I do with this machine stops about 3-4 hours in with the dreaded click click of filament not extruding , which you would think is caused by a filament block , its not blocked at the hot end and everything as far as I can tell is setup correctly.

What I have not changed , main board , stepper motors, firmware.

have I missed anything ?

Hiya! Your friendly assistant mod Slashee here.

This isn't really about improving prints so I'm moving it to "third party products" forum.

 

I guess my first questions would be:

• Are you printing off an SD card (or whatever the Ender-5 Plus takes) or over USB (and in the latter case, from just your main computer or a dedicated system like OctoPrint?)
• Are you using the same gcode file for both printers?
• How is the filament being held (like is it just on a holder that comes with the printer or are you crazy like me and have a few holders sitting on a table next to the printer being fed into its tent through Bowden tubing and held on top by a thing I printed just for that)?
• Other than the stopping after 3-4 hours, are they performing equally well? Printing at the same speed, with the same accuracy, etc.?

You could try swapping the motherboards between the two to see if the motherboard is the problem but sometimes Creality have used different boards for the same model printer just so they can get enough, so if they're different I don't know whether swapping them would work.

 

If it just suddenly stopped working I doubt it's the firmware but anything's possible. You could try reflashing it but with Creality printers that's really somewhat of a flip of a three sided coin whether it'll make it better, not change anything, or worse.

 

About the stepper motors: are you noticing any performance degradation or loss of accuracy as the print goes longer? I mean, even if that's happening it could be a long shot, but any difference in behaviour between the two is worth bearing in mind.

Thanks for the reply and shifting the thread ,

Printing off an SDcard , my original CR10 runs off a pi but not the enders.

Yup same gcode.

Standard filament holders.

yep works fine for a certain time then the damn thing messes about so I could use that printer for small objects but that seems a bit of a waste.

thing is it was working fine when I bought the 2 printers at the same time but now this one is just annoying me.

Im giving it another shot now and we are a couple of hours in , working fine .

actually 7.5 hours

 

I stopped the print reheated the nozzle and the filament flows freely
