Welcome to the SeeMeCNC Community

I'm awaiting the arrival of a used Delta printer I just bought.

I design in zbrush and then fix stls in Netfabb. I also have most other software if needs be like Magics, Repetier, Meshmixer etc. Most of my modeling I get printed by a company in London using an SLS machine but I've decided to take the plunge and get my own modest printer to try a few things out. However, I've noticed that all the softwares have print beds that are rectangular, so how do I set the printer up for a round bed like the Delta ones ?

Any help would be appreciated.

I've answered my own question. Repetier Host has a 'Printer Shape' in the settings menu where you can set up a round bed.

Cura and KISS do as well. Delta's are common enough now that most softwares will allow you to configure them to your machine.

In Slic3r you just use the Reprap settings for the round bed.

So as someone who has tried almost every slicer (Craftware, Repetier, Mattercontrol, Slic3r, Cura etc) Right now, im finding Cura is KILLING it for me... Craftware has a GOOD future ahead of it, but right now its slicing is wildly inconsistent.
Mattercontrol is second for me, but right now cura is just providing fantastic results.
