To get your printer running, start by generating an STL file of your model, then open it in your slicing software. Use the printer’s default settings if you have them; if not, look up profiles for your exact hardware from the manufacturer or community forums. Make sure the slicer’s printer dimensions match your actual machine, or it may try to print beyond the build area and cause layer shifts.

Before printing, home the printer. It should go to the correct corner (or center, depending on setup) without overrunning the build plate. If it homes short, your endstops or bed position may need adjusting so you can use the full build area.

To start the print, you can connect the printer to your computer with a USB cable and a program like Pronterface — click “Connect” in the Print panel, ensure the printer is on, and verify the printer settings match the manufacturer’s recommendations. Once connected, check that the extruder and heated bed reach their target temperatures. Then send the print job.

Keep in mind that a direct USB connection to a PC is risky, since any computer hiccup will kill the print. A more reliable option is printing from an SD card or USB drive, or using a Raspberry Pi running OctoPrint, which gives you remote control and monitoring through a web browser. Whichever way you go, watch the first part of the print and don’t leave it unattended until you’re confident it’s progressing well.
