Heaven help me - I've just bought a delta kit :-)

S3d has all that stuff built in. So tend to use the printer control panel for that kind of stuff.
sppedwise i'm talking about overall maximum speed. I leave everything else to s3d. Never changed any of the default slow down speeds.
My mantra: if it's not broke, don't try and fix it :-)

You can switch off the updates in windows 10.
Right click start button, go to control panel, view large icons. Go to administrative, cluck services. Go down to windows update, right click, select properties, disable on startup and shutdown.

And no it's not a patch on 7 :-)

Mount wise i intend to use the metal struts Not the corner pieces. Fix the mount with 2 bolts and strutnuts - so they cannot move, and attach the springbolts to those.
Currently trying to decide how to mohnt a 350mm by 5mm (probably) bed.
will 3 5mm bolts and springd be enough. Or should i go for a 6 point mounting system. Weight wise it'll probably never have to suppirt more than a couple of kgs and the springs i have are pretty heavy duty. But when you look at the heatpad and printbite, it's going to be a seriouschunk of aluminium.
My bolts and springs are much shorter than the k200. all my electronics are roof mounted, the the springs are simply for physical bed levelling. They will be screwed up pretty tight.

Can't see how your bracket helps. The only real problem is stopping the bracket moving. If it's still only attached at one point and not locked into place, how is it an improvement ?
