@dc42 I have heated chamber as well, it would be great if you could implement in future build.
Thanks and Best,

Thank you guys for the comments and your ideas.

For oozing before Z calibration I am planning to Install brush like in Makerbot. But I don't know how effective will it be.

@deckingman I will check your page as I would also like to use mechanical switch.

I will update as soon as I have modified my printer.

Hi,

I am really happy that I upgraded from Arduino+Ramps system to Duet.

Now I want to add mechanical (micro)switch to my printer. The switch that one have in CNC machine to measure tool length.
We print different materials, from PLA to Filaflex and etc... Flexible material we mainly we print with 0.8mm and PLA with 0.4mm nozzel for that we just exchange hotend with fins. Because of it, it happens that height of tool isn't exactly same and we would like to add mechanical switch which can be used to set exact height between bed and nozzle.
Printer may travel to this switch before every print so that everything works safely.

Is it some how possible to do that?

Thanks.
