What i meant was something else, for a cartesian bot which completes a layer / slice, by moving X and Y together. Then the Z is used, but in separate movements, distinct from x and y, because Z is...

Check the following line in your Configuration.h and see what it's set at: #define HEATER_0_MAXTEMP 275 275 looks to be the default but it's possible that's set lower for your firmware, especially if...
View ArticleRe: RUMBA random disconnects
One possible cause is because you have a ground loop putting excessive current through your USB cable. This can be caused when your printer ground is at a different voltage to your PC's USB ground....

In fact, I did some more testing, I did try what you said (never rule out a idea ;-) ). But since i'm using a laptop, there is no loopback ground possible. (at lease I havent found one) But I did find...
