Strange issues with second Creator

[curious aardvark]

sounds like the new one isn't heating the bed as much as the old one - so just put the temp up.

One piece of kit you might consider buying would be an infra red thermometer.
This is the one I've got - useful pieces of kit, cheap too. Also fun :-)
You do spend a lot of time initially pointing it at things to see how hot they are. Also if you've got a dog - odds are it'll go mental chasing the laser dot

IT'll basically give you an accurate reading on the relative bed temps.

I will add that I have so far never been able to print anything without a raft.
I figure when i get round to setting up slic3r with the right gcode and linking it to gpx I might be in with a chance. The first layer needs to go down hotter, slower and with a little more extrusion. Can't do that with makerware, but at the moment rafts are fine.
Just seems like a waste of plastic, but print wise they're pretty idot proof ;-)
