One A1 Mini, a stack of plates, zero babysitting

The Chitu PlateCycler is a physical plate swapper for the Bambu Lab A1 Mini. SimplyPrint AutoPrint treats it as a cycle-dependent clearing method: set a max plate count, queue your jobs, and the printer ejects each finished plate, loads a fresh one, and starts the next print on its own until the stack runs out.

What is the Chitu PlateCycler?

The Chitu PlateCycler C1M, made by ChituSystems, is an automatic plate-switching system for the Bambu Lab A1 Mini. After each print finishes, it ejects the entire build plate and loads a fresh blank one from a finite stack, so the printer keeps going without anyone touching it.

In SimplyPrint this is a cycle-dependent clearing method for AutoPrint. Because the supply of fresh plates is limited, you tell us the maximum number of plates in the stack, and AutoPrint stops cleanly once that many cycles are done, rather than trying to print onto a plate that is no longer there.

How it works in SimplyPrint

Once the PlateCycler kit is installed on your A1 Mini, turning it into a hands-off station takes three steps in your account.

1. Connect and enable AutoPrint

Connect your Bambu Lab A1 Mini to SimplyPrint as usual, then enable AutoPrint on the printer. AutoPrint is what auto-starts queued jobs and clears the bed between them.

2. Pick Chitu PlateCycler and set max cycles

Choose Chitu PlateCycler as the clearing method, then set the maximum plate count to match how many fresh plates you loaded into the stack. AutoPrint counts each swap and stops when it reaches the limit.

3. Queue jobs and walk away

Add jobs to the print queue. AutoPrint starts the first print, swaps the plate when it finishes, and starts the next - repeating until the queue or the plate stack runs out.

Frequently asked questions

The Chitu PlateCycler C1M is built specifically for the Bambu Lab A1 Mini. It is a dedicated kit for that printer, not a universal mod.
As many as there are fresh plates in the stack. The PlateCycler loads one new plate per cycle, so the unattended run length equals the number of plates you load. In SimplyPrint you set this as the max plate count, and AutoPrint stops once that many cycles are done.
Yes - the Chitu PlateCycler C1M is a physical kit sold by ChituSystems. It ships ready to use. SimplyPrint then drives it through AutoPrint, which is included on Pro and above.
Instead of you popping the plate off and starting the next job, the PlateCycler ejects the whole finished plate and loads a blank one automatically. AutoPrint then starts the next queued print, so the A1 Mini keeps running while you are away.
Yes. AutoPrint pulls jobs straight from the print queue, starts them, swaps the plate when each finishes, and moves on to the next - up to your max plate count or until the queue is empty.
