I am using luban for the first time and am trying to do a 3d print. The “generate g-code” button is grayed out and I am unable to press it. Can anyone help me solve the problem? I have attached the print. [first print.zip](https://forum.snapmaker.com/uploads/short-url/a11TP74rFukoGGdlqJ3gh9VcvvQ.zip) (1.1 MB) ---

The file you supplied doesn’t tell us anything. Take a screen grab of Luban. Is your machine selected correctly? Are you trying to slice something to large for it to print? -S ---

I am using the A350 and everything seems to fit. I am not sure why objects are red. If I move them to the center, and change nothing else, they turn white. ![image](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/b/bbce6df11b8813da8099093124be2aa5af10aed9.jpeg) ---

I sliced this file but it worked. Software version: V3.15.0. ![First_print](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/b/bdfc526f3740be63b481f55d865984f79895bafc.gif) ---

Huh. I used v3.15.1. I restarted the software and reopened the file I sent to you and the error was gone. Strange error. ---

That’s the first thing you’re going to try to print on your SM? You really need to start with a calibration cube or a benchy or something simple and get things dialed in before you try to print something that complicated, let alone multiple items. -S ---

Thanks. I already added supports to overhangs and bridges, used the highest quality print setting, and the printer does its own auto-leveling. What parameters should I trying to dial in? How do I physically do that on the machine? (My print DID fail. It looks like the bottom layers are messy/unaligned) ![image](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/2X/6/6ee9062a3befdabd422abc69f4ab19688a9e75ab.jpeg) ---

Well, as a jumping in point you can read this: > [@Snapmaker 2.0 Initial Calibration Settings / Experiences](https://forum.snapmaker.com/t/snapmaker-2-0-initial-calibration-settings-experiences/9928): > > Hello all, I thought I’d type up my setup and calibration procedures for future reference since I haven’t seen too much of this information in a single place before. Hopefully this is useful. There are other introductory posts worth reading such as: @xchrisd’s [3d Print Guide\_Walk Through](https://forum.snapmaker.com/t/3d-print-guide-walk-through/5945) The first thing I did was update to the latest firmware, change the auto bed levelling to 5x5 grid, and do an auto level. I’m impressed with this process, it works pretty smoothly. Looking ahead, I’ve fou… ---

@brent113 Thank you. That is an almost overwhelming amount of information, but I will try. ---

My first print looked the same, I did not adjust the 0 point with a piece of paper. When I did that it turned out fine.
