Have you got your printer working with "off-the-shelf" 3D printer software? If not, may I suggest that as a first step (forgive the pun).Īnd if you think you can improve on the printer software to make it more economical why not modify the "off-the-shelf" program and give your modification back to the community where it is likely to be welcomed. In other words I think the motion of all the motors has to be part of the same program. To the best of my knowledge the motion of the extruded material has to be matched with the motion of the table on which the object is being created. How could the motor be running if the tempearture is not high enough to melt the plastic - assuming, of course, that the motor you mention is the extruder motor - which you omitted to say. Post a link to the datasheet for the motor. If anyone can give me some help as to what do with the programming that would be awesome as i have not much of a clue.Īmong many "first" thoughts I wonder if a RAMPS board with A4988 drivers can provide enough current for a Nema23 stepper. Those are the basic requirements i want to achieve. Pretty much my goal is to make the extruder work like this:ģ.heater cartridges power and and begin to heat upĤ.thermistor determines the temperature to which the cartridges heat up to.ĥ.extruder tip now at set temperature by heater cartridges.Ħ.While steps 3-5 are happening Nema 23 stepper motor is running at set speed and 12v fan is also running.ħ.pretty much keep steps 3-6 running until power supply is turned off. I am up to the stage of wiring up my ramps 1.4 board which is ontop of an ardunio mega 2560 and i have not much of a clue as to how to program the ardunio to do what i want.Īttached i have a wiring diagram of my ramps board (ramps 1.4 connectors diagram also attached). My design is somewhat along the lines of this. Im part way through a little school project of mine where i am creating a filament extruder to save a bit of $$ on 3d printer filament.
