Multi-user computer-numerically-controlled machine

A computer-implemented method comprising:

• modifying a set of instructions for a computer-numerically-controlled machine in response to receiving, at a server and from a first computing device, a first modification to the set of instructions, the first computing device previously associated with a user account stored at the server;
• in response to an abandonment signal received at the server and from the first computing device, removing an ability of the first computing device to modify the set of instructions, the abandonment signal indicating that the first computing device is no longer modifying the set of instructions;
• enabling an ability of a second computing device to modify the set of instructions, the enabling based at least on a connection signal received at the server from the second computing device, the second computing device previously associated with the user account stored at the server;
• and
• modifying the set of instructions for the computer-numerically-controlled machine in response to receiving, at the server from the second computing device, a second modification to the set of instructions.

A system comprising:

• at least one data processor;
• and
• at least one memory including instructions, which when executed by the at least one data processor, cause operations comprising:
• receiving, at a computer-numerically-controlled machine comprising a laser configured to deliver electromagnetic energy to effect a change in a material within an interior space of the computer-numerically-controlled machine, a command to be executed by the computer-numerically-controlled machine;
• determining a hardware state of a component in the computer-numerically-controlled machine at least by receiving, from the component, data indicative of the hardware state;
• identifying an origin of the command, the origin of the command comprising a user identification of a user who sent the command and/or a machine identification of a device that sent the command;
• determining, based at least on the hardware state of the component and/or the origin of the command, that the command is allowed to be executed by the computer-numerically-controlled machine, the determining comprising applying a set of rules defining when the computer-numerically controlled machine is allowed to execute the command;
• and
• in response to determining that the computer-numerically-controlled machine is allowed to execute the command, executing the command at the computer-numerically-controlled machine.

• enabling an ability of a second computing device to modify the set of instructions, the enabling based at least on a connection signal received at the server from the second computing device, the second computing device previously associated with the user account stored at the server;
• and
• modifying the set of instructions for the computer-numerically-controlled machine in response to receiving, at the server from the second computing device, a second modification to the set of instructions.

A non-transitory computer medium including program code, which when executed by at least one data processor, cause the operations comprising:

• receiving, at a computer-numerically-controlled machine comprising a laser configured to deliver electromagnetic energy to effect a change in a material within an interior space of the computer-numerically-controlled machine, a command to be executed by the computer-numerically-controlled machine;
• determining a hardware state of a component in the computer-numerically-controlled machine by at least receiving, from the component, data indicative of the hardware state;
• identifying an origin of the command, the origin of the command comprising a user identification of a user who sent the command and/or a machine identification of a device that sent the command;
• determining, based at least on the hardware state of the component and/or the origin of the command, that the command is allowed to be executed by the computer-numerically-controlled machine, the determining comprising applying a set of rules defining when the computer-numerically controlled machine is allowed to execute the command;
• and
• in response to determining that the computer-numerically-controlled machine is allowed to execute the command, executing the command at the computer-numerically-controlled machine.
