I bought both the i3mks3+ and the MMU2S - should I do a mks3+ print before upgrading to the mmu2s?

I am not a 3d printing noob, but I am new to Prusa.

I got the prusa primarily for the MMU2s.

Good engineering tells me test the base unit - then add on the MMU2s, and the impatient child tells me, just go ahead and upgrade and sort it out later.

 

Any advice?

Best Answer by K7ZPJ:

1) Build the printer including the extruder modifications for the MM2S. 

2) Test the printer without the MMU2S to make sure it works perfectly.  

3) Build the MMU2S and install it on the printer.

4) Take the time to get the adjustment for the extruder filament sensor work right.  If it isn't adjusted right, the MMU2S will never work.  Taking time on this step will save you hours of troubleshooting.  The adjustment on the Finda sensor is important too, but not as hard to get right as the filament sensor in the extruder.

Remember getting it done right is a lot more important than getting it done fast.

The MMU2 can be troublesome and it helps to understand your base unit well so you know where to put your hex screwdriver in when the machine is not doing what it should. But technically there is in my opinion no reason not to install both immediately 🙂

Thank you for helping me act like an adult.  My other printer does not have such sensors and so that's going to be some new hex twisting - good tip.
