Platecycler C1M Review: Best upgrade for the Bambu A1 Mini
The Chitu Systems Platecycler C1M is a $79 add-on for the Bambu Labs A1 Mini that automatically swaps build plates, clears finished prints, and queues up the next job without you touching a thing. After using it for a full month, I can say it has completely changed how I approach batch printing. If you want to wake up to a pile of finished prints, keep reading.

How the Platecycler C1M Works
The Platecycler C1M mounts onto the back of your A1 Mini’s heat bed and adds a tray that holds up to 10 PEI spring steel build plates. The swap sequence is elegant. When a print finishes, the hotend moves up to apply pressure on a cable connected to the ejection mechanism. The bed slides forward, then slowly moves back while the ejector lifts the finished plate off the magnetic bed. On that same backward pass, it picks up the next plate from the tray. As the bed moves forward again, it ejects the old plate and loads the new one into position. The whole cycle takes about 3 minutes, and then it’s printing again.
You don’t modify the printer’s firmware, and you don’t learn a new slicer. The Platecycler slots into your existing workflow with one extra step: combining your plate files using Chitu’s software.
Setup: Under 5 Minutes
The Platecycler comes mostly pre-assembled. You slide on the bed cable guide, push the gripper onto the back of the heat bed, drop in four springs, attach the tray, and tighten a single bolt. The tray holder has a built-in latch that snaps onto the Y-axis rail. The ejector clips onto the front the same way. Slide the lifting lever onto the Z-axis rail, move the spool tube holder into place, and clip two included push blocks onto the bottom of the heat bed. That’s it.
The four included build plates come with all hardware pre-installed, so there’s no additional assembly. Load the plates, run the test G-code file Chitu provides, and confirm all four plates load and eject correctly. Mine worked flawlessly on the first try.
The Software: Platecycler App
Once your plates are sliced in Bambu Studio, you export the G-code to your computer rather than sending it directly to the printer. From there, you load the file into the Platecycler app, available as a web app at platecycler.chitusystems.com or as a downloadable .exe for offline use.
The app shows each plate with filament usage, lets you drag and drop to reorder jobs, set how many copies of each plate to print, and configure loop repeats so the same set of jobs runs multiple times. When you’re happy with the queue, you generate a single combined G-code file. Open that file in Bambu Studio, confirm everything looks right in the timeline, and send it to your printer like any normal job. Filament estimates and times calculate correctly from within Bambu Studio.
Real-World Test: Number Characters with AMS Lite
For the first test, I printed a set of number characters with each number on its own plate, using different filament colors from the AMS Lite. I sliced everything in Bambu Studio, exported the multi-plate G-code, loaded it into the Platecycler app, and generated the combined file. About 4 hours later, all four prints were done. The color changes worked flawlessly, and the plate swaps were smooth every time.
One thing to note with multi-color jobs: each file needs to have the filament colors assigned to the same AMS slots. If one file has colors in a different order than the others, the Platecycler app won’t automatically reorder them to match. It’s an easy fix in Bambu Studio, but worth knowing before you queue up a big batch.
Real-World Test: Holiday Door Corners with AMS
The second test was a set of holiday door corners with multi-color designs. Each corner prints in about 45 minutes, so without the Platecycler, you’d need to be standing by the printer after every single one. With the Platecycler, I loaded up four corners, walked away, and came back about 6 hours later to a finished stack. No babysitting, no failed queues from sitting idle overnight. The A1 Mini and Platecycler handled the AMS color changes and plate swaps without a hiccup.
Why This Makes Sense for the A1 Mini
The A1 Mini has a smaller build plate than many other printers, which means you’re often splitting larger projects across multiple plates anyway. The Platecycler leans into that. Instead of cramming a plate full of parts and hoping none of them fail, you can print each part on its own plate. If one fails, it only affects that plate. The rest of the queue keeps running. Combined with overnight or all-day printing, you get a lot more output from the same printer with a lot less time spent watching it.
Verdict: Should You Buy the Platecycler C1M?
At $79, the Chitu Systems Platecycler C1M is one of the most useful A1 Mini accessories available. The hardware installs in minutes, the software is straightforward, and it works with the tools you already use. There’s no learning curve worth mentioning. You just gain the ability to walk away from your printer and come back to finished prints.
If you’re a hobbyist who does any batch printing, this is a fun and practical upgrade. If you’re running a print farm or small business with an A1 Mini, it’s a no-brainer. Pair it with a $219 A1 Mini and you have a fully automated 24/7 print setup for under $300 total.
