If you are using the Recommended LDO Motors for x/y then IIRC the recommended drive current for them is around 2.4 amps don't think the 2209's can supply that but I could be wrong
Just looked it up the x/y motors are 2 amp motors and you wouldn't run them at 100% power but it is getting close to the driver limit so a good point.

yes they are 2amps RMS so you would run close to that in fact I do know that the devs use around 2.4 amps to them to get the additional speed out of them (They are high Temp motors as well)

AS jens has asked what are the tool parking motors and wouldn't you need 3 if you have 3 tools?

@dougal1957, thanks .... that pretty much only leaves the 6HC board as a viable contender.

not really as you could use a 3hc as a slave to a duet3mini but you don't have to run the XY motors flat out if you don't want to but I wouldn't go below 1.6A

@dougal1957, grrrr, just as I made the decision ..... this is hard

I knew the question would come up.
This is something that has been on my mind for a long time.
I want to park my tools in the front, but here they are in the way for maintenance work. So I was thinking about moving a tool platform in Z.
But this should only happen when needed, not for a tool change.
For example, at the end of a print to get more space to reach in.
I already have a concept and first CAD drafts for this. -
@diy-o-sphere ah ok makes some sense i guess but that could be done with low current motors I guess you would have to ensure that they always come bake to the normal position quite accurately tho.
