Just installed everything and adjusted gcode, all that went fine, but when we print the Purge Fast gcode to extrude the material, nothing happens. The machine seems to vibrate a bit, but nothing is moving and the file seems to take forever, it already says it is over an hour and it is not moving.
Can you tell me more about the material you are trying to print? There are some materials that simply don’t have the right characteristics for extrusion.
actually we are using it without any material.
The point is, that the lift is not running. The motor seems to work but there is no action on the threaded rod.
Do you have the allen key inserted? If the allen key is not inserted, the lead screw will not move at all. (The lead screw itself will not rotate…the gearbox in our product pushes the lead screw up/down – but only if the allen key is inserted.)
yes, the key is inserted but nothing happens.
Is there any other setting we have to note?
Can you send me a photo of how you have the Discov3ry set up? The movement rate of the lead screw is about 10 mL per hour (so the full 60 cc is about 6 hours of printing). It will be really slow if you are trying to watch it. But you can place a piece of tape on one of the four guide screws, perhaps 1 cm above the syringe grip (white 3d printed part where the allen key is inserted), then double check the distance after running it for 20 minutes or so.
I have also a similar case. I am using nutella as a material. Does it really purge very slow even if i set it to purge fast? Is my set up in my photo attached correct? Thank you!
For some reason, I don’t see your photo. The Discov3ry is designed for power (torque) over speed, though, so this can be confusing when people are used to the fast speed of filament loading and printing.
It typically will take is about 6 hours to print the full volume of a 60 cc syringe, so that is 10 cc/hour. As the material moves through the tubing, it will advance at a rate of about 1-2 cm/minute.
If you still have questions, please let me know.
