Who needs Staggered Start?
Anyone running multiple 3D printers on a domestic or office circuit: print farms in basements, garages, offices and warehouses, university and school labs sharing a wall outlet, and makerspaces where the breaker keeps tripping when class starts. If you've ever blown a fuse heating up your printers, this is built for you.
Heating is when 3D printers draw the most power
A 3D printer's heated bed and hotend account for the vast majority of its power consumption - and they spike while heating up, then settle once they hit temperature. That's why you can usually run a farm fine 24/7 but trip the breaker the moment you try to start all the printers at once.
Staggered Start solves this by limiting how many printers can be in the heat-up phase simultaneously. Once a printer reaches temperature and starts printing, another printer in the queue is allowed to start heating. The rest wait their turn in a Pending start state.
Set the limit once, start your whole farm in one click - safely
Say your farm has 20 printers, but your circuit can only handle 3 printers heating at the same time. You set the Staggered Start group's heating limit to 3. Then you use 1-Click Print, AutoPrint, or just hit start on every printer at once - the platform takes care of the rest:
- 3 printers begin heating. The other 17 sit in a "Pending start" state.
- As soon as one printer finishes heating and starts laying down filament, the next pending printer is released to begin heating.
- The cycle continues until every print is running.
You can cancel a pending print at any time - the next one in line takes its place automatically.
Not sure where to set the limit? Use the heating limit calculator
We've built a free calculator to give you a starting number. Tell it your region (US/North America or EU/rest of world), your circuit breaker rating in amps, and whether you're running small, medium or large printers - and it'll suggest a safe heating limit.
The calculator is a guide, not a guarantee. Real-world numbers depend on your wiring, filament type (different materials need different bed and nozzle temperatures), and what else is plugged into the circuit. The reliable approach: start with the calculator's number, try heating 5 at once, drop to 4 if it trips, drop to 3 if it still trips. Once you stop tripping, you've found your limit.
Setting up Staggered Start in 4 steps
Configuration takes about two minutes. Open Settings > Staggered Start, decide your limits, pick which printers it covers, save.
1. Set your heating limit
Drag the slider to the number of printers your circuit can safely heat at once.
2. Tune temperature thresholds
Lower the wait threshold (e.g. 200°C tool, 20°C bed) to move the queue along faster.
3. Optional: cap downloads too
Limit concurrent G-code downloads if your network can't handle 20 at once.
4. Choose which printers it applies to
All printers by default - or pick specific ones, models or groups.
Multiple stagger groups for multi-room and multi-location farms
If your printers aren't all on the same circuit - different rooms, different floors, different buildings - one global limit isn't right. Staggered Start lets you create multiple stagger groups, with their own heating limit per group. Group your printers by location, by circuit, or by power budget. Each group is staggered independently, so the office and the basement can both start at full speed without affecting each other.
Bonus: stagger file downloads too
Power isn't the only thing that bottlenecks at startup. If your printers all sit on the same internet connection, downloading 20 G-code files at once can saturate the line and slow every printer's start. Staggered Start groups also let you cap how many printers can download files at the same time - same UI, same group, separate limit. Great for sites with limited upload bandwidth or older WiFi.

Works for every print start - web, app, queue, AutoPrint, API
Staggered Start kicks in no matter how the print was started. Hit print from the SimplyPrint web platform, the mobile app, via the public API, through AutoPrint, or from the print queue - if you have a stagger group set up, your fleet stays inside the limits. There's no "forgot to enable it" - once configured, it's automatic.
