When you open the Slic3r gcode in MatterControl, do you immediatly just click "print" or do you try to slice it again? At what point does it add the leveling to the gcode?

I'm asking because I've tried what you're talking about but with Cura. I added the Pulse as a Prusa in Cura and saved the gcode for my model. Then I opened that gcode in mattercontrol and attempted to print. Unfortunately, when using the Cura gcode, MC would push the print head into the bed. I couldn't figure out how to get it to print level using gcode from another slicer.

I'm using a Pulse A-734 with MatterControl. My issue is that whenever I try to print larger items that require supports, MatterControl takes hours and hours to slice. I started slicing an item last night at midnight and its still going. The item is something like 1300 layers. This morning it was on layer 199.

I can print small items, and items that don't require supports just fine. But as soon as I try to print something large with supports, MatterControl can not finish preparing the G-Code. I'm not sure what to do from here. Since MatterControl is the only software that will work with my older Pulse, the printer is basically unusable for large items.

Any suggestions? I'm using a Microsoft Surface laptop.
