H2D AMS filament placement recommendations

[Ukdavewood]

I am only a week into my H2D experience, which is mostly completely positive.

One of the few concerns I have got is about the filament placement recommendations.

I think the logic should be changed slightly to only make recommendations for moving filaments between AMS’s if it has a reasonable benefit.

My latest print for example first recommended I swap every roll between two AMS’s - so that they were exactly the same - just in opposite AMS’s.

Then later after some model refinements I was recommended to make a few filament movements - but tried to see what the impact of using connivence rather than optimal was - and it was only a saving of 0.2g of waste, no time saving and actually 1 more filament change.

So I think maybe there should be a 1 or 2g waste allowance before it recommends you swap rolls around.

Also because my Mac is in a different room to the printer it is a little bit inconvenient trying to remember quite a few AMS filament swaps - which will get worse once I add 2 more AMS’s - so a way of seeing the recommendations on the printer display would be handy too.

Also having Non BL filaments is a bit more awkward too - due to having to tell the printer what changes you have made.

Convenience - 0.2g more, with 1 less change

To be honest, adding more AMS units doesn’t give you additional options for swapping filaments — you still have only two nozzles. For example, red PLA can only be assigned to either the left or the right nozzle, not to anything else. If you already have two AMS units, one assigned to each nozzle, adding more won’t provide extra swapping flexibility.

What it does offer is the possibility to load the same filament into AMS units on both sides, so you can avoid swapping between nozzles altogether.

In my setup, I have one AMS2 and two AMS HT units on the left, as my left nozzle mainly serves as a support nozzle, and two AMS2 and one AMS HT on the right.

thanks yes I was thinking having some doubles might help reduce the number of swaps.
Might also be needed for multi coloured models needing the full build width.
