Because of this, some requests for extra functionality will not be accepted. It aims to be beginner friendly and as such where possible the interface is kept as minimal as possible. The aim for the site is to provide compatibility with the majority of 3D printers. This site is not a web based slicer, therefore it is limited in some ways. This website then uses Javascript to modify the contents based on user inputs. The gcode generated by this page is originally from Simplif圓D. Validation has been built into the forms to only allow sensible min and max values, however this is not foolproof. Only print this gcode when you are present, alert and capable of stopping the printer in case of emergency. Preview the gcode in your slicer or Zupfe GCode Viewer and print at your own risk. Every attempt has been made to ensure this is safe but ultimately there always is risk in running pre-sliced gcode from the internet.
