why hotend and printbed lose connection?

[artohautala]

Well ,
I have difficulties... my felix 3.0 printer loose communication about 1 minute or 5 minutes or so
after starting print...
connect button is still green and z,x and y axis works but suddenly hotend and printbed start to go
cooler and there is no more filament going out of course...

I'm using dell laptop and com1 usb connect
what are the best settings for communication ?
Yesterday I printed 2 hours and then it falled but today nothing seems to work ...

Try a different USB cable. I've had problems like this and resolved with a simple usb cable without ferrite cores.
