The invention discloses a temperature control chip for a 3D printing nozzle, a temperature control system and a 3D printer. The temperature control chip comprises a temperature control circuit, a debugging circuit and an interface module used for being connected with an upper computer. Wherein the temperature control circuit is used for controlling the temperature of the nozzle, and the debuggingcircuit is used for debugging the temperature control circuit. The debugging circuit comprises a first debugging register, wherein one end of the debugging register is connected with the output end ofa target module in the temperature control circuit, and the other end is connected with the interface module; a data selector which comprises a first input end, a second input end, a gating end and an output end, wherein the output end of the data selector is connected with the input end of the target module, and the first input end is used for inputting an input signal of the target module in anormal working mode; a second debugging register, wherein one end of the second debugging register is connected with the gating end of the data selector, and the other end is connected with the interface module; and a third debugging register, wherein one end of the third debugging register is connected with the second input end, and the other end is connected with the interface module.
Description
technical field [0001] The invention relates to the technical field of 3D printing, in particular to a temperature control chip for a 3D printing nozzle, a debugging system and a 3D printer. Background technique [0002] In the composition structure of the nozzle of the 3D printer, the temperature control circuit used to control the temperature of the nozzle is an important part, and the effect of the temperature control circuit determines the printing quality of the final product. [0003] In the design and development process of the temperature control circuit, it is an essential debugging step to capture the internal signal of the circuit for observation and control. However, generally speaking, the interface of a circuit system to the outside is only its IO pins, and the internal signals are buried inside the circuit; for developers and debuggers, the internal signals of the circuit are neither visible nor conveniently directly Control, it is difficult to realize the de...
