Only last week I decided to give the AMS a go, I’ve been single filament printing for about 7 years now so wasn’t in a rush to set it up on my new A1. Anyway, although I seem to have 2 colours set up in studio and 2 colours on the arms, when I click print, it does the whole job with one colour and the same one colour on the tower…I’ve now spent 2 days trying to get the printer to SEE 2 colours and now I’m getting to the stage where I’ll stop attempting to use the AMS. I must have missed something but I don’t know what…any suggestions please? Thanks, Nige
This is a screenshot of a simple round 20mm disc. I put it into studio and painted a different colour dot in the middle. I then sliced it ok and I downloaded the Gcode, sent it to the printer after I set the AMS up with the same 2 colours and had no warnings at all on the screen, clicked print and all I keep getting is a white disc, no dot in the middle…
Did you assign the red a location in the AMS! and then link that spot to the filament in the AMS?
Thanks for the help Rob. I’m a total newbie to multi colour so know zero. I have just done a shot of the Prepare box, but as to your ‘Link’ in the AMS I’m lost 
I changed the red to pink
Did you choose use AMS at the printer? I print over the network but there is a “Use AMS” checkbox in the workflow. I’m wondering if that was missed by transferring the gcode manually somehow.
Use AMS…I don’t know how to get to it?
Sorry got a print going. So network printing dialog looks like this and you’ll note the checkbox. IIRC a similar set of checkboxes comes up when you reprint something from the printer screen. If you’re not getting the option maybe it’s not being set.
Did this get resolved? I am having the same issue with one of my AMSs. It’s been printing just fine and then all of a sudden it will only print the 1st color. It will process/load the 2nd color, but just air prints, and continues that through the rest of the print, but never extruding the 1st color again. Everything is set to acknowledge the use of the AMS, assigned colors in AMS, and my other AMSs work just fine. I have tested with different models, and filaments, so not an issue with the model or filaments.
In looking over slice, you can see the colors in the model as well as the flushing tower.
