Beautifully implemented, thank you @rickwierenga!

I was about to start this today to facilitate the new ztouch_probing 😅

To ensure I understand everything in here:

You extended the rail system to include a "teaching carrier", which is the panel at the righthandside of the machine that houses the

• teaching needle rack,
• the place&shift metal strip for tips discarding, and
• the the gripper parking position.
  You also modelled the metal teaching needles as 300ul_tips/standard_tips.

Is that correct?

yes. the 'carrier' only includes the teaching needle rack atm, but we can possibly have it be the parent of the trash and grippers as well.
