Custom-made extruder
Hello everyone
For our custom printer, we want to work with a syringe pump that allows our liquid metal to flow through a custom nozzle. To control this flow, we would like to use the output of the extruder on our motherboard. This output is normally provided to drive a stepper motor. Our Syringe pump works with a different drive so we would like to somehow convert these signals using an Arduino, for example, to something that our syringe can understand. However, this is a fairly complex and perhaps not always accurate process.
Does anyone know if, in addition to the standard outputs on the board (for the stepper motor), there might be additional outputs (e.g. to the TMC2209 board) for reading out the correct printer speed and print command so that we can process it and pass it on to our extruder?
I look forward to your creative ideas
Thanks!
