Printing with PBT
I was wondering if I could get some help printing in PBT (Polybutylene Terephthalate).
The company I work for has a client that will need 20 or so prototype electronic enclosures 3D printed in PBT.
Our 3D printer is a Prusa i3 MK2S. We will be upgrading to a MK2.5 as soon as it arrives.
I found a source for PBT filament, but I don't see any setting in PrusaControl for PBT. The temperatures required are 240/250 degrees for the extruder & 100/110 degrees for the platen.
There are also PC+PBT (Polycarbonate + Polybutylene Terephthalate) filaments available with required temperatures at 235/250 degrees for the extruder & 110+ degrees for the platen. This may be an option but our client specifically asked for PBT.
I'm fairly new to 3D printing. Everything I've done so far has been in PLA.
Any information you could provide would be a big help.

Re: Printing with PBT
I must say I have not heard of that filament type before this post. Anyway, you can use Slic3t Prusa Edition to get more control over your prints and has a lot of other options than PrusaControl. PrusaControl only offers predefined settings for most common filament.
You can install Slic3r PE with the latest driver package. Chose a filament that is closest to your required printing setting (something like ABS) and tweak the setting from there. I think it's fairly straightforward to use, but as a start just choose ABS in the filament drop-down and then in the Filament tab change the temperature to what you are looking to print. Have a test print and then tweak some more setting after that if you still need adjusting. Most setting will give you a small hint about what they do if you hover your mouse cursor on top.
