Hi guys. I've just finished some experimenting with my machine. Since loading Rich Cattell's marlin fork with auto calibration and auto bed levelling, which is great btw, I've noticed my print head hesitating ocassionally during a print. When this happens it normally leaves a blob of ooze behind. If I remove the smart graphics display the issue goes away and also if I don't send a G29 before I print. I was running a 1/32 micro steps. I have reset the driver jumpers to 1/16. The problem seems to have cured and there is no apparent difference when my machine runs. The extra load from display, bed levelling and 1/32 seems just too much for my Mega 2560 equipped Rumba board. Maybe something to look out for if anyone has weird issues.
