MK2S extruder on a MK2

If I print out the MK2S extruder body, cover, and idler will it mount to my MK2 using the existing nuts, screws, and X-axis carriage?

Hi Richard,

I suggest you print x-axis carriage as well, there is a new attachment system for extruder's cables. It will significantly reduce bending of cables and increase overall endurance. However, you will also need a pair of printed cable holders, ideally from PETG (part of our MK2S upgrade kit).

See Chapter 5 Step 24 and Chapter 5 Step 31

In general, you can use the majority of the screws and nuts from MK2 to MK2S, but there are some extra needed, like M3x40 for this cable holder or M3nS for P.I.N.D.A. sensor.

To answer your question, it will fit, but I recommend to change the X-carriage as well.

agree, you have all the needed parts - the extra parts (2 bolts and 2 nuts) needed are in your original 'extra parts package' I printed all the parts in PETG and they worked fine except the hex nuts did not stay in place and need a little adhesive (I used caulking compound) to hold their position until the bolt could 'grab' the nut. This was unlike the original parts which had a very tight fit for the nuts. Note that the PINDA no longer uses bolts on the treads - the bolts must be removed!
