Yes, that sounds about right. (If you find out anything different, please update EMCRepRap [
reprap.org] with what you learn, OK?)
Once I tell my Sanguinololu+Sprinter to set the extruder temperature with the G-code M104 (or M109) and set the bed temperature with M140 (or M190), then the Sanguinololu+Sprinter actively maintains that temperature,
even after it is disconnected from my laptop.
My understanding is that all other RepRep electronics+firmware works about the same.
I see there are several hackerspaces in Switzerland -- [
hackerspaces.org] .
They probably know lots of good sources for parts, and other people building RepStraps.
I hear there is at least one developer in Switzerland -- [
www.fabberworld.com] .
So I am surprised that Switzerland is not yet on the list of RepRap user/developer groups [
reprap.org] .
Could you add Switzerland to the list?
I see that most of your neighboring countries have RepRap developers:
Germany [
reprap.org] , Austria [
reprap.org] , Italy [
forums.reprap.org] .
Are any of these groups close enough that you could talk to them?
