As the title says. When you slice one model its fast enough. But as soon as you add more than one it takes an absolute eternity. It gets to 50% fast enough but after that every 1% takes 10-30 seconds. I dont even know how long it took to slice because I had to walk away from the computer. And then when thats done it takes another eternity to send the file to the printer. Why cant i just put the file on a usb stick and use that? If i have to walk to the printer to press the button to start anyway, why not use a more efficient transfer method. Or make it faster. But seriously, this software is unusable. I dont have time as a business to wait hours to be able to start a print. Is this a common issue or just me? Because if this is a norm, no matter how good the printer is, this problem makes it unusable.
