RE: Mini R2 Update

Did anyone already installed the R2 parts? Especially for the MINDA probe?

Is there a "How-to install" manual somewhere? I didn't find anything on https://manual.prusa3d.com.

There are pictures in the blog post https://blog.prusaprinters.org/2019-recap-plans-for-2020-and-original-prusa-mini-update/ which shows how it shall look like, when installed, but there are further screws and nuts to be mounted, and I'd like to know which sizes I have to use.

There are no extra screws required for the probe mount, three screws hold the old part and the new part.

Two go through the mount and fan and thread into the heat sink, one clamps the probe.

The only part that requires a new screw is the fan spacer/cable clamp, I grabbed the correct screw from the spare bag, no nut is required.

Same, while changing parts is probably not rocket science, I'd also appreciate some list of additional parts like screws and nuts, and how to replace it properly. Quite possibly full assembly manual is used internally and not yet in state of being published.

We posted at almost the same time, the reply above your post should be helpful.

Reposting an edited version for accuracy:

There are no extra screws required for the probe mount, three screws hold the old part and the new part.

One goes through the mount and fan and threads into the heat sink, one goes into the X-Carriage, one clamps the probe.

I still need to print and replace the X-carriage and display box. So far the only part that requires a new screw is the fan spacer and clip, I grabbed the correct screw from the spare bag, no nut is required.

RE: Mini R2 Update

Thanks guys.

This is truly helpful for everyone, who will deal with that.

I manly was wondering if there is a manual, which I just didn't find.

 

One more thing to add in your recap: The only part that requires a new M3x20 screw is the fan spacer/cable clamp.
