Fri, 01 May 2026 00:00:00 GMT Buying Guide https://pamfinds.com/3d-printing/bambu-lab-ams-2-pro/ https://pamfinds.com/3d-printing/bambu-lab-ams-2-pro/ The Bambu Lab AMS 2 Pro is the active-drying successor to the original AMS, adding a PTC heater and circulation fan that dries hygroscopic filament (PETG, nylon, PA-CF, TPU) while you print. Same 4-spool capacity, same 16-color daisy-chain ceiling, but no more swapping spools between AMS and a separate filament dryer. Thu, 30 Apr 2026 00:00:00 GMT Review https://pamfinds.com/3d-printing/bambu-lab-ams-ht/ https://pamfinds.com/3d-printing/bambu-lab-ams-ht/ The Bambu Lab AMS HT is a single-spool tower-format dryer with active drying up to 85°C — the highest temp of any Bambu AMS. It's the only AMS that works with the A1 series AND the P1S/X1C, making it the most universal Bambu spool solution. Designed for engineering filaments (PA-CF, nylon, PC) that need temps the AMS 2 Pro's 65°C ceiling can't reach. Thu, 30 Apr 2026 00:00:00 GMT Review https://pamfinds.com/3d-printing/bambu-lab-ams-lite/ https://pamfinds.com/3d-printing/bambu-lab-ams-lite/ The Bambu Lab AMS Lite is the open-frame 4-spool multi-color system designed exclusively for the A1 series ($149). No enclosure, no active drying, no humidity sensor — just 4 spool holders, RFID detection, and the same multi-color magic as the full AMS at half the price. Trade-off: hygroscopic filament (PETG, nylon, TPU) needs a separate dryer. Thu, 30 Apr 2026 00:00:00 GMT Review https://pamfinds.com/compare/bambu-ams-vs-ams-2-pro/ https://pamfinds.com/compare/bambu-ams-vs-ams-2-pro/ The original Bambu AMS ($249) handles 4 spools with passive desiccant drying. The AMS 2 Pro ($349) adds a PTC heater that dries filament continuously at 30-65°C — the upgrade is worth $100 more if you print PETG, nylon, or TPU regularly. PLA-only printers in dry climates should stick with the original AMS. Thu, 30 Apr 2026 00:00:00 GMT Comparison https://pamfinds.com/best/best-bambu-ams-2026/ https://pamfinds.com/best/best-bambu-ams-2026/ Bambu sells four different AMS units across two printer families. The AMS Lite ($149) is for A1 series. The original AMS ($249) is the P1S/X1C standard. The AMS 2 Pro ($349) adds active drying for hygroscopic materials. The AMS HT ($249) is the only universal option with 85°C drying for engineering filaments. This guide ranks them by use case so you can buy once and not regret it. Thu, 30 Apr 2026 00:00:00 GMT Buying Guide https://pamfinds.com/networking/gocoax-ma2500d/ https://pamfinds.com/networking/gocoax-ma2500d/ The goCoax MA2500D is the most-recommended MoCA 2.5 adapter on r/HomeNetworking — a $85 plug-and-play box that turns any coax run into a 940 Mbps wired ethernet link. Built on MaxLinear's MxL3710 SoC with a 2.5GbE port, it consistently hits 920-945 Mbps real-world throughput between two units across typical home coax.
