Safety
What this software does and does not do.
WARNING — This software is not an emergency stop. Your machine must have a hardwired E-stop that removes motor and spindle power. Keep it within reach whenever the machine is powered.
Pause and Stop job
Pause and Stop job sit in the same place in every view and are never blocked by sign-in or by a mode. Escape pauses from anywhere. They are controlled stops sent over a channel that is not safety rated, and they may be delayed or never delivered.
What Stop job does depends on the connection. When this page can move the machine, Stop job stops motion, clears the queue, and turns the spindle and coolant off. On a read-only connection it sends a feedhold, like Pause, which may leave the spindle and coolant running or pause them according to the firmware and board settings. Neither is an emergency stop: use your E-stop to remove power.
Report a problem
Something wrong with run, the firmware or the board? Run gathers what it already knows, shows you every piece before anything is posted, and opens the right place: run or firmware issues on GitHub, or the forum for questions. Reporting sends nothing to the machine.
What this tool cannot guarantee
- It cannot stop your machine in an emergency. Only a hardwired E-stop can.
- It cannot guarantee that a stop command arrives or how quickly it arrives. The command passes through the browser, the operating system, USB and the firmware.
- It cannot stop the machine if the browser tab closes, crashes, is discarded or sleeps, or if USB is lost. The controller keeps running its queued moves.
- It cannot turn off a spindle, laser or coolant if the controller does not obey or the link is lost. On TinyG a feedhold or a program stop (M0/M1) leaves the spindle running. At a tool change (M6) Run sends M5 and M9 itself before it shows the tool-change card, and the controller has to obey them.
- It cannot see your wiring, your switches, your workpiece or the people around the machine.
- Its preview and bounds checks use its own interpreter and can disagree with the firmware.
- It cannot detect mechanical faults: lost steps, loose couplers, broken switch wires.
- A completed bring-up journey records what you attested and what small tests showed. It does not mean the machine is safe.
- Your account stores files and settings. It does not make them correct or safe for a machine. Review every change before you use it.
- It is not certified to any safety standard.
- It cannot protect you if the code served at run.synthetos.com is itself replaced by an attacker. Keep your E-stop within reach.
The full safety contract is at run.synthetos.com/safety (opens in a new tab, so this workspace keeps its connection).
