Extruder unintentionally going at 500% speed


Recommended Posts

Posted · Extruder unintentionally going at 500% speed

I was looking through the forums for any similar issue, and this is exactly what is happening with our printer:

https://ultimaker.com/en/community/17646-what-the-heck-is-going-on-with-my-extruder

Unfortunately there seems to be no responses.

This just started happening today. I have made no hardware changes in the past 3 weeks and use this every day. I have manually inspected my gcode and there is nothing wrong with the script. This behaviour occurs usually somewhere between layers 0 and 5. I am printing small parts one at a time (one part in one gcode). I am able to print 0-5 parts successfully before all of a sudden this issue happens, and effectively grinds the filament due to the crazy fast extruder speed, necessitating a material swap. After changing out the material, if I turn off the system for a couple minutes, it seems to work again, printing with the same gcode file during which the issue occurred.

Not sure if this is hardware or software... Suggestions?

    Hi,

    Can you give us your Gcode ? We'll try it to test if it happens the same thing. Then we could know if it's a soft problem or not and continue until we solve the problem (:

    The PCB is probably getting too hot. I recommend removing the cover over the PCB (none of my machines have had the cover in a year) and then also adding a fan blowing under your printer a bit. You can tilt the printer by putting one side on a book or something to get better air flow. The printer will print fine upside down or sideways or any orientation so don't worry about that aspect. Just don't tip it so much it accidentally falls over with a bang.
