I seemed to have one of the lucky ones from the start, that was very quiet and never had any issues, so the sounds now are disturbing. Once I've got the Kossel finished, I'll look into belt tightening/pulley replacement/whatever might be the source - but it still prints fine even though it's loud now and I like to keep at least one running, to support repairs or mod work on the others

I don't advise going beyond about 2400 very often, if ever.

Edit: To be a little more clear, after S3d's upgrade to 3.0, I've left the speed settings at the defaults, which does have movement set to 3600 mm/m but the max printing speed at 1800.

Thank you so much for everyones replies n help.

First thing you should do is level your bed with the paper method.  Once that is done check your speeds, I have simplify working decently now after a lot of bs but the stock speeds in simplify seem to fast for the machine. Even then I still can't get simplify to print tiny parts as nice as the default slicer.

I'm just waiting to get pissed off enough to put repetier on, I'm convinced the stock firmware has something in it to mess with 3rd party slicers.

I assure you it does. I use S3D on my RAMPS based Da Vinci and I am able to print rods that are 3mm in diameter at 40+mm/s and they come out flawless. Even at 60mm/s they are still near perfect.

I concur with Carl - S3d even with stock hardware flashed with Repetier, produces some of the best prints any of my printers have made, down to 0.1mm layers reliably - so long as the bed leveling and height are carefully set.

I cannot make my Davinci 1.0 work with Simplify 3d?? Its as if the extruder is too close to the bed maybe? I get a clicking noise and the extruder moving around the bed but not laying any filament down. Any help would be greatly appreciated!!
