Wandering printing

[Coopoon 0]

I seem to be having a issue when printing taller prints. The stl file looks fine in Cura but when printing the printer moves off the original start point and print creeps off line. Any idea what is going wrong?

Looks like you have a pulley loose.

This is called shifted layers, you can find a guide how to fix it HERE

You can navigate to the guide from the Support section on the ultimaker website.

Labern,

Thanks of the guide load of stuff there!

Checked all the belts and pulleys but looks like is issue with the stepper motors overheating and shutting down to cool while printing, have looked that up and seems to be a common problem. Trying to see if adjusting the current to the motor works if not will try to install some fan cooling or heatsink addition.

Thats good you have found the problem.

@mnis has designed covers that either use passive cooling or can hold fans. they can be found Here

You maybe able to adapt them for the extended or ask mnis nicely to add a model for you.
