Hello,
I usually esport GCODE with CURA and i've tried Slic3r for the first time today. Unfortunately i've come immediately to a damage :/
After get the GCODE and opened it with PRINTRUN, the extruder started working the first layer by litterally ENGRAVING the aluminium board. It's like the Z offset was lower than usual.
Beside the damage to the workbench, the extruder is now CLOSED: no filament comes out from it, and there's no way to clean form outside.
Any advice?
Does anyone guess WHY all this happened?

Cura was designed for Ultimaker machine and the Z axis is reversed I believe. I normally use slic3r but when I tried Cura and hit print my Z axis tried to go to the top of the machine to find zero.
I don't know if there is a way to reverse this in Slic3r but I am sure someone else will chime in here.
As for the nozzle you can either buy another tip if yours is changeable or buy a micro drill bit off ebay in the size of yours and re drill it. Most people use a glass plate over the aluminum both to provide a very flat smooth surface but also because it's sacrificial if something goes wrong and can be cheaply replaced. In your case Borosilicate glass would not have sustained any damage (it's very strong).

I doesn't work that way. When the bed is up against the nozzle on a machine like an Ultimaker it is at 0 just like when a Mendel variant has its nozzle near its bed. It then builds upwards just like any other machine where the nozzle gets further away from the bed as the Z increases. The fact that the bed moves down instead of the nozzle moving up makes no difference they still move away from each other.

Maybe the offset works in the opposite way. Check in the gcode file for the first layer height (Z something) and see if it is making it go the opposite way, as in negative when you wanted positive.
