The Chitu PlateCycler clearing method for AutoPrint

The Chitu PlateCycler clearing method for AutoPrint


The Chitu PlateCycler is an automatic plate-switching system for Bambu Lab printers, made by ChituSystems. There are two kits: the PlateCycler C1M for the Bambu Lab A1 Mini and the PlateCycler C1 for the Bambu Lab A1. Both swap the whole print plate between prints, so SimplyPrint can keep the queue running unattended. This guide covers what it does, how to select it as your AutoPrint clearing method, how to pick the right kit, and the plate-limit setting it needs.


The Chitu PlateCycler runs as a clearing method inside AutoPrint, which is part of the Pro plan and up.


What the Chitu PlateCycler is

The Chitu PlateCycler is a plate-switching system made by ChituSystems, sold as a dedicated kit per printer:


  • PlateCycler C1M: for the Bambu Lab A1 Mini.
  • PlateCycler C1: for the Bambu Lab A1.


According to ChituSystems, when a print finishes the PlateCycler swaps out the print plate for a fresh one, so the printer keeps going without anyone removing the finished part. Paired with AutoPrint, it lets the printer work through a stack of plates on its own.


Both kits use the same clearing method in SimplyPrint. You pick the kit as a variant, and SimplyPrint loads the matching clearing gcode. The two printers move differently, so the variant has to match the kit you installed.


Selecting the PlateCycler on a printer

You set a clearing method per printer, from the AutoPrint settings.


  1. Open the printer's control panel and find the AutoPrint widget.
  2. Open the AutoPrint settings and find the Clearing method section.
  3. Click the method selector and choose PlateCycler.
  4. Choose the variant for your kit: PlateCycler C1M (A1 Mini) or PlateCycler C1 (A1).
  5. If SimplyPrint offers to Change printer model, accept it to switch the printer to its PlateCycler model (see below).
  6. Set a Max AutoPrint cycles value to match your plate stack (see below), then save.
  7. Flip the AutoPrint switch on for the printer.


You can view the PlateCycler clearing gcode under the gcode editor and adjust it if your setup needs it. Each variant has its own default sequence.


Changing the variant later

The variant dropdown sits next to the Clearing method heading in the AutoPrint settings. Pick the other variant there to switch kits.


If you never edited the clearing gcode, SimplyPrint swaps in the new variant's default sequence. If you did edit it, your edits stay as they are, so check the gcode matches your kit before you save.


Always keep a variant selected. With Select variant... chosen there is no default clearing gcode.


Printers that used the PlateCycler before the A1 kit was added are set to the PlateCycler C1M (A1 Mini) variant. Their clearing gcode did not change.


The PlateCycler printer models

SimplyPrint has a printer model for each kit: A1 Mini Chitu PlateCycler C1M and A1 Chitu Platecycler C1. When you pick the PlateCycler while editing a single A1 Mini or A1, SimplyPrint offers to switch the printer to the matching model. Choose Update model to accept, or Keep current model to leave it.


The PlateCycler model gives the printer a more accurate printer image, and because it is a separate model from the standard A1 or A1 Mini, you can sync AutoPrint settings across all your printers with that model.


Set a max cycle count

The PlateCycler works through a finite stack of plates, so SimplyPrint asks you to set a Max AutoPrint cycles value. This is how many prints (plate swaps) the printer runs before it stops and waits for you to reload plates. Set it to the number of plates your stack holds, so AutoPrint never tries to load a plate that is not there.


What SimplyPrint does each cycle

With the PlateCycler selected, each AutoPrint cycle runs like this:


  1. The print finishes and SimplyPrint detects the completed state.
  2. The bed cools to the temperature (or for the time) you set, so the part releases from the plate.
  3. SimplyPrint runs the PlateCycler clearing sequence for your variant, swapping the finished plate for a fresh one.
  4. SimplyPrint verifies the bed is clear. With a camera connected, AI bed check can confirm visually before continuing.
  5. SimplyPrint matches the next queue item and starts it, until the max-cycle count is reached.


For how matching, scheduling and verification work in detail, see the AutoPrint overview.


Buying the PlateCycler

Both kits are sold by ChituSystems. Once you have picked a variant, the Learn more about PlateCycler link in the AutoPrint settings goes to that kit's product page. The Learn More / Buy link in the method picker goes to the ChituSystems store, which lists both kits.
