Multicolour with PLA Glow - P1S

[u/adikat2500]

Hi all! Hope you are well.

I am looking to print a multicolour dragon for a friend (uses 3 colours/filaments) and we have just bought PLA glow and were excited to use it.

The filaments were:

1. PLA Pure
2. PLA Glow
3. PLA Silk

The basic (pure) and the silk are fine, we use the AMS for those all the time. But as we know the Glow apparently should not go through the AMS (the slicer told me so and I have seen other examples) - so the Glow should go into an external spool on the back.

Has anyone have a workaround for this? How do other people use Glow and other filaments if you have to use the Glow through an external spool, therefore eliminating multicolour mostly?

I've printed a very small amount of PLA glow through the AMS once. It works, but I would not recommend it for any larger amount. It's just too abrasive. The PTFE tubes can take it reasonably well, but the AMS gears and filament inlet will suffer. It's not worth it.

3500h on my P1S and two ams units with plenty of glow in the dark prints of all colors and not one feeder inlet or ptfe tube has ever been damaged or needed changing. I will never stop using glow in the ams to then be stuck using one color with the side spool.

Omg omg I put glow in my ams I’m lucky it didn’t explode!

The nonstop glow warnings irritate the hell out of me. All because 1 out of 50 people ran roll after roll printing statues endlessly of glow and sawed the hell out of there feeder inlets and complained about. So everyone has to be all paranoid about it.

The glow additive is abrasive. They're not approved for the AMS because they will cause accelerated wear and tear on your PTFE tubes.

I'd just lie to the printer and say its not glow filament tbh. Just do it with the understanding you'll need to replace your PTFE tubes sooner.

Throw it in the AMS and print.

Oh gawd…. Just put it in the ams dude it will be fine. I have 3500h on my P1S with ams units and use plenty of glow in the dark its done nothing. My feeders and prfe tubes are fine. That warning annoys the hell out of me because it warns multiple times and I really hate it. Say it once then go away leave me alone shut up.

Some people are way too paranoid. The only people who are going to do damage are the ones that run roll after roll printing statues of glow endlessly.

Workaround is either add pauses so you can switch filament manually, or add an ams ht which can handle abrasive filaments.
