So in marlin my extruder won't move but in repetier it moves perfectly. It isn't a temp issue, i have it at 200C while trying to move it. If i move it in marlin by 1mm it moves but if i move it by any more it won't move. Also i can't move my extruder through any software like pronterface or mattercontrol. I can upload my marlin and repetier firmware if necessary.
The best way to get your extruder motor actually turning again is by identifying whether you have a mis-wired motor, have a current too low, or have a faulty stepper motor altogether. Once you know the cause, the fix is to rewire your motor, get a higher voltage going through or get a replacement extruder stepper motor.
Turn on the power and set parameters such as pressure, temperature of each temperature zone, holding time, and automatic feeding setting through the PLC system. Add the prepared pre-sintered powder to the hopper or barrel (manually or automatically). Start the machine. Cut the extruded PTFE tube to the required length.
In most of the extruder, the screw speed is changed by adjusting the motor speed. The motor rotates at full speed of about 1750rpm, but it's too fast for an extruder screw. If the rotation at such a rapid speed, it will produce too much friction heat and plastic retention time is too short to prepare a uniform, very good mixing of the melt.
Dec 16, 2017 · I tried a clean build of 1.1.3 - it built, but did not fix the issue. I tried going back to 1.1.1, but still the extruder did not work. The driver is good, the motor is good. So that leaves A) software or B) the RAMPS board itself. I've ordered another board ($7 on amazon!) and we'll see if that fixes the issue.
turn the knob to raise the extruder so that it is at least an inch above the print bed. 22. Select Quick Settings > Preheat PLA. Note that the screen will not change immediately, but will return to the home screen and display Preheat PLA at the bottom after about 30 seconds. 23. Monitor the temperatures of the extruder and plate on the LCD display.
After a while the extruder stopped extruding properly, it was hardly outputting any filament at all. At this point I stopped the print, as it was failing badly. I then had a look at the extruder, to try and nail down this problem. It puzzled me for a little while until I realised that the small gear was turning freely on the motor shaft.
Aug 17, 2013 · First, the stepper motor for this extruder can be extremely small and mounted directly above the extruder. This opens up the doors to easily creating multi-extrusion printers that can handle more ...
