The S5 does come with a sensor to detect if filament ran out. To my knowledge, we do not sell an extended spool holder for carrying 2kg filament on the printer.

@Jason7373 Yes. You can use third party materials with the Ultimaker S5. You will need to input a new material profile in Cura to record your settings.

I have that printer. Love it for PLA. Love it for the PLA/PHA blend. ABS? Well, not so much. ABS in all forms hates me and my Ultimaker.Is it a requirement for you to print ABS?-Chris

@ProfkanzWe have (8) rolls of 1.75 available, pretty much brand new rolls. Trying to upload pictures, but not able to figure it out.

No. You cannot just replace the nozzle. You have to change the entire print core. Currently Ultimaker does not sell cores with stainless steel nozzles.

Thank you guys so much! I'm so excited to get back to printing - now with faster speed and better resolution!
