I have a few designs that require more than 4 colours, but I only have one AMS unit. I was wondering if it was possible to switch the filament spools mid-print so that I can achieve prints like this:
My initial thought was to pause the print at certain points to give me ample time to switch the filament spools but I ran into two issues:
- Pausing only seems to be possible at the beginning of the layer. As shown below, there are instances of layers having 6 colours per layer, which does not give me the opportunity to change them during a pause.
- Switching filaments manually presumably will not initiate proper purging, which will have an adverse effect on the quality of the print.
I’m hoping there is a solution - perhaps the printers knows that the filament spools need to be swapped during the print and will self-pause and give me a notification to change the spool, with a confirm button to allow it to purge and continue, but I couldn’t find any confirmation on this and I’m tentative to try it and waste filament.
I would be grateful for any advice please.. preferably that avoids spending £200 on another AMS..
Side note: It is expensive, but having a second (or third) AMS is a really nice thing to have. Mostly for filament storage so you are not constantly swapping spools.
For the solution, this one is pretty simple:
You have 5 color options on the X2D. 4 in the AMS and 1 in the secondary nozzle. You might have to disconnect the track switch if you have one.
Add a pause in the print profile at the top of where the black is, then swap out that black with one of the colors of the buttons (you will have to set one of the colors to “black”)
You can attach the print profile if you would like. It might be easier to show you on an example.

The other option is to simply change the model so the coloured parts print separately and then are added/snapped/glued in to the model. This will save time and filament poop. The other added benefit is that the coloured parts can be printed face down on the a textured bed.

Thank you for the advice, I’ve attached the print profile - that would be very helpful thank you

You can also print 5 colors all from the main nozzle by buying a 4-in-1 PTFE adapter and use the external spool holder or even a dry-box with a fitting for a PTFE tube. You can buy 4 liter plastic cereal boxes from Amazon and use those as a dry-box.
