Hello! You can play with your slicer and 4 colours to make it look good and the preview most of the times will give you a good idea of how is going to look.

Hey! You can still print more than 4 colours using only a single AMS. Slice the file as stated in the description and define the first four filament changes according to the first four colours and your AMS. Assign the last four colour changes again to the same slots in your AMS in this kind of manner: Colour #1 = slot A1 Colour #2 = slot A2 Colour #3 = slot A3 Colour #4 = slot A4 Colour #5 = slot A1 Colour #6 = slot A2 Colour #7 = slot A3 Colour #8 = slot A4 The sliced image will look very wrong but it does not matter. When the printer is finished with colour #1 in slot A1 and has started printing from slot A2, replace the spool in slot A1 with colour #5. When colour #2 is finished printing from slot A2, swap this spool to colour #6 and so on. In theory you could print as many colours as you want as long as you are physically present to manually change the spools. Yes, its tideous but it works. To minimize the amount of manual swaps you can wait until colour #4 starts printing and then exchange the first tree spools at once but don't forget to change the spool in slot A4 to colour #8 towards the end of the print. Also make sure to push the filament deep enough into the AMS so the first stage feeder is able to recognize it. However, the AMS does not update the spool/filament parameters mid-print. This means you are stuck with the same filament settings (temperature, flow rate, K value aso.) in each AMS slot. So make sure to use either a standard profile across the board or to use the same filament brand in each slot. I hope this helps :)

That's awesome, I never thought about this approach. Thank you for this.
