Invented by Robert LADANYI, Individual
The Individual invention works as followsThe 3D printer includes: a printhead with an extruder driver positioned for feeding filament into the heater, a printhead positioning system that moves the printhead relative to a printing surface, a motordriver that is connected to extruder and can control the extruder’s operation, a sensor that has a feed-rate sensor that detects the rate of feed, and a controller that is programmed to receive signals that indicate the feed rate of filament from the sensor.

Referring to FIGS. “Reference is made to FIGS.
It would be useful to have a 3D Printer that can at least eliminate or reduce some printing mistakes.
The 3D printer includes: a printhead with an extruder (that is, stepper) motor positioned to feed filament into a heating element, a printhead positioning system configured for moving the printhead relative to a printing surface, a driver stepper that is connected to extruder and can be used to control operation of extruder, a sensor that includes a feed-rate sensor positioned in order to detect the rate of feeding of filament, and a controller system programmed to receive signals from sensor module, which are indicative of the sensor module, and operate the extruder, a a a a a a a a a a a a a a feed rate a feed rate a feed rate a feed rate, a feed rate a feed rate a sensor module a feed rate a sensor module, the sensor module, that are indicative the sensor module, that are indicative the a sensor module, that indicate the feed rate sensor module,

receive signals that indicate the feed rate for the filament from the sensor module
The sensor module can be used to control the stepper motor.
The 3D printer also includes an X-encoder to detect rotation of X-positioning motor and a Z encoder to sense the rotation of Y-positioning motor. A control system is included that includes an intercept controller, which is programmed for receiving a high level control from a command feeding device. This high level control indicates a target printhead position and is programmed with low level commands that move the head to that target position.
The retrofit system comprises an X encoder positioned to sense rotation of the X positioning driver, and an Y encoder positioned to sense rotation of the Y position motor. The retrofit system comprises an X-encoder to detect rotation of a Y-positioning motor and an X-encoder to sense the rotation of an X-positioning motor. It also includes an intercept controller programmed to receive a high level command from a command feed device, wherein the high level commands indicate e target position for the printhead and that is then programmed to send low level commands to the X and Y positioning drivers to move the printhead to the target location.
