Any printer on Bambu's own connection or a Klipper/Moonraker bridge works, listed or not. No affiliation with the brands shown. Check your printer

Rackrew runs the queue. You run the hardware.

Upload a file and say how many you need. Rackrew picks the printer, checks the spool and starts the print. It only asks for you when a machine needs hands.

It checks the spool first

Rackrew compares the grams a job needs with what is left on each spool. If the print will not finish, that printer is skipped.

Prints keep running offline

The bridge on your network talks to your printers directly. If your internet drops, updates arrive late. Prints do not stop.

The screen you open every morning

What is printing, what needs you, and what happens next. One page, not a dozen tabs.

The Rackrew Overview screen: two printers printing, one idle, one with an empty spool, a 14-day throughput chart and the next three jobs in the queue.

Free for two printers, forever

Every feature is in every plan. You pay for how many printers you connect, not for what you can do with them.

Questions

Setup guides, the bridge, and the API are covered in the docs.

Read the docs
How long does setup take?
About ten minutes. Sign in, plug in a Hub or run our agent on a spare machine, then add your printers.
Does something have to stay running at home?
Yes, a bridge. That is either the Rackrew Hub, or our free agent on a PC or Raspberry Pi you already own.
Where do my printer passwords live?
On your own bridge, not in our database. We never write them to disk in a form we could read back.
Can I really use it for free?
Yes. Two printers, every feature, no card, no time limit. You only pay when you connect a third printer.
