MK2S Hotend replace  

Re: MK2S Hotend replace

No, that's the "lite" version which was used on the Mk1.

Actually, not true; it will fit, but this extruder has significantly reduced heating capacity.

Unless you buy replacements direct from PR, you may find some differences (PR doesn't have a connector in the thermistor cable and has a modified heat break).

Re: MK2S Hotend replace

Thank you. I have purchased the Lite version and will try to do some printings.

I have made some calibrations and they are ok.

Anyway tomorrow I will try to print something in two hours and see what happens.

Ill tell, thank you

Which can be the consecuences of the reduced heating capacity?

From memory... The Lite6 was used on the Mk1 printer. At that time, E3D were saying that the Lite6 had about half the melt capacity that the V6. Which means that your max volumetric will be less than 6 mm^3/sec.

Also, the Lite6 has an integrated aluminium heat break, so you may suffer from greater heat creep. The PTFE tubing is shorter because of the integrated heat break.

However, if you are running the MMU1, tool changes will be better (they will not suffer the issues caused by the SS heat break).

You will have to be more careful to avoid collisions, as the aluminium heat break is more susceptible to bending.

Overall, the Lite6 is not a good replacement (downgrade) for the V6.
