Re: Voltage controlled extruder signal - 9 years ago
Hey This sounds like a good idea! Thanks for your help. However, I'm a bit lost when it comes to the firmware. Where is the gcode parsing done in the code? I wonder if it wouln't be easier to somehow edit the gcode beforehand with an M42 command according to the Gcode's feed rate.by Pelzeb0b - Firmware - Marlin
Voltage controlled extruder signal - 9 years ago
Hi guys I'm trying to connect a syringe pump to my 3D printer (UM2+). The extrusion speed of the pump is controlled by an analog voltage (0-10V) signal . I will connect the pump to the digital pin 13 on the ultimainboard and use an analogWrite to get the voltage for the speed. This is still fine. However, now I want to link this signal to the extrusion signal of the printer. As I understand itby Pelzeb0b - Firmware - Marlin
