I purchased this Robo C2 with a particular project in mind. It's basically a cube which is just shy of the X/Y print volume of 5"x5" of this printer. I carefully researched things before the purchase and was satisfied that I'd done my homework, so-to-speak. I've successfully printed many things so far, each with rafts. I've dialed in the z-adjustment and so each raft adheres beautifully. So then, I laboriously learned Autodesk Fusion 360, created the several components inside this cube, placed them, created all kinds of constraints and finally, finished designing the bottom of the box and exporting this as an STL file. I then next brought this into Cura and it isn't happy, noting that I downloaded and created the profile for the Robo C2 printer already. Cura indicates that it can't slice it because it exceeds the size of the print volume. Note that the cube's sides are each 120mm = 4.72". Researching this a little, if I turn off the raft in Cura (which would extend the X/Y a bit) as well as supports and then scale the X/Y down to 117mm then at least it will allow a slice to a GCODE file. Transferring this file to the printer and attempting to print it doesn't adhere in the least. 1) It just feels to me that this printer (without a heated bed) with PLA pretty much requires a raft or it doesn't adhere (suggest any Cura tweaks if you have a no-raft fix for this). 2) It would be great if I could convince Cura to print the maximum print volume instead of a fraction of it. 3) It would be great if I could convince Cura to lay down a raft which only extends the X/Y by, say, 2mm only. 4) I really don't want to have to go back into Autodesk and change the entire design to make it raft-friendly in size since I thought I had a 5"x5" print volume on this. The inside of the cube holds a variety of parts and I'm already pushing the limits to allow for internal cabling, etc. It would be nice to not have to re-engineer this. Also, there are external holes/ports and other contraints which I don't want scaled down. Any thoughts?
