I would like to sell the AMS I own for the 2 Pro since then I don’t need to buy a separate dryer while maintaining them multicolor capability. I know that people won’t pay the full $350 (unless they have not heard of the new stuff released) so I am expecting to sell it for maybe $290-300 and make up the difference with my own money. Any opinions on this and where I should sell (if you think I should)?
I would be surprised if anyone were to pay this much for a used (first gen) AMS.

As the AMS 2 Pro won’t dry while printing, if you print a lot, not being able to dry while printing could be very annoying. This goes for drying the filament that’s currently being printed as well as drying a filament you’re not using. So it may be better to have separate dryer (but of course, both is always better).

No, the AMS2 is a nice upgrade but it is not a “Sell your existing and get it” upgrade
nor would anyone pay almost what brand new AMS1s sell for ($310-$320) for a used one.

I have both, but with little experience with the Pro of course. One issue I see with the Pro already is that a normal workflow is loading one spool at a time as needed into the AMS. An AMS is seldom batch loaded, at least for my workflow.
All filament in the AMS needs to be retracted entirely onto the spool before the heater is turned on. Not a big effort, but still an extra step.
I was unsure if my Sunlu 4S was made redundant with the heater in the Pro. It is not. Drying only with the Pro would be inconvenient and conflict with printing. I’m glad to have the dryer in the Pro and I’m fine with paying $50 for it. But it doesn’t replace the Sunlu.
Buying the HT may be a better choice for many prople, especially if using the technical filaments.

I actually think about replacing one of my AMS for a AMS 2pro. Not for the drying but for the stronger and faster motors. The PTFE tube is quite long and with a few curves so that the AMS has a really hard time pushing filament up to the print head. It sometimes sounds like it barely makes it.
Can somebody confirm the stronger driving of the new AMS?

That’s exactly why I would like the AMS 2 Pro, except I also want the integrated dryer.
The AMS 2 Pro is a great buy if you have no AMS. But if you have an AMS and are looking to sell it to fund a new AMS 2 Pro, I think you are going to see it very difficult to get a good price for it.
IMO, the new one is worth the cost increase, which is minimal (+$30), but that’s only if you don’t have one. If you do, the convenience of adding the heater is minimal. What is more compelling is the ease of maintenance and more durable feeders.
On the heating, if you have no PLA in the AMS, yes, the convenience is great. But if you have PLA in it, its not a lot different than moving rolls from an external dryer to a normal AMS. As mentioned before, any PLA in the feeder needs to be un-fed and tied off to start drying. Yes… PLA can’t be dried at PLA temps, while in the feeder. They are worried about deformation of the filament.
Stronger… can’t confirm, but it may be. But it is SIGNIFCANTLY faster. Surprisingly faster.
keep in mind you cannot dry and print at the same time
even if you’re drying slot 1 and printing from slot 2. AMS2 Pro doesn’t support it.
There is a saying here: “Every day a stupid person gets up somewhere”.
If you can find someone who will take a used AMS1 off your hands for the price, then that would of course be an option. But the AMS2 costs more or less the same as the AMS1. So if you buy one now and maybe don’t need the heating function, you must have a good incentive to buy an old, used AMS - and that’s usually an incredibly good price.
Therefore … No, it’s not worth it.
I simply ordered an AMS2 without further ado and now have 2 AMSs. But I also have a Sunlu S4, because the AMS can’t heat AND print at the same time.
I have two AMS2 Pros, and the longer PTFE tube works fine on one. I have one unit on top of the printer with a short tube, and the other sitting off to the right on a milkcrate with a longer tube. I haven’t measured it, but it’s probably 20 inches long. It was the longest I had. I would like a longer tube though. For me and the right-side AMS.
