Thanks! Now on the subject of controllers, motors and drivers, what brand/model would you suggest for this application? The machine will be approx 2'x3' Gantry style (would like to if possible be able to convert to a mill to mill aluminum molds, but that isn't top priority). I am planing on using stepper motors for the pumps and probably for the xy as well. My goal is to spend as little as possible without sacrificing too much quality...I guess that is everyones goal...
And yet another question regarding the plastic dispensing piece. I plan on using the stepper driven pumps, but would it be more accurate to build a screw injection pump (keeping in mind the small cavity size)? Does anyone have suggestions on a heater for the lines that will carry the material (length approx 5')?
Thanks again! |
