While is printing, the Extruder unload the material!?!??!!? #3368

Closed fbarcenas closed 6 years ago

fbarcenas commented 8 years ago

This is very rare... After work some hours and all is very well, the Extruder 0 move around -100 aprox and the filament go out and continue working.... Of course continue working in the air, because the filament is totally unload...

Also before of this, the X axis moves to search the Sensor home X-, move to X- and after return to work...

Some idea?

Second test with simplify3D, everything fine. Problem solved?

I do not understand, it was fixed but now you have the error again ?

fbarcenas commented 8 years ago

When i am thinking than all is solved, the printer fail again! Is very desperate. My actual test is with all wires separate, i am thinking than maybe i have problem of interference in the wires PULSE/DIR and interference in 24V wire of input. Can be this?

Perhaps not is a problem of firmware?

I had this happen with a filament change from the LCD menu in RC6. It worked fine and went back to the proper place and then ejected the filament again. I'm trying to see if I can reproduce it.

fbarcenas commented 8 years ago

I not use LCD, i remove LCD and SD for remove possible problems. Thanks for help

Thank you for your interest making Marlin better and reporting this issue but this topic has been open for a long period of time without any further development. Marlin has been under heavy development for the past couple of months and moving to it's last mile to finish the RC cycle and release Marlin v1.1.0. We suggest you to try out the latest RCBugfix branch and reopening this issue if required.

I am having the same problem with RC8. Printing from the SD, about a hour in the printer stops, makes a few random moves and then ejects the filament. A few times it continued and a few it just stopped, I have formatted the card (not sure how that will help),

Printing from USB at a lower baud rate helped, but about 2 hours in the print just stopped. This was including ping pong mode.

From time to time the LCD shows garbage in the screen till you click the encoder wheel.

I used RC6 but it just reset the printer once you click to print from SD. RC8 prints from SD, but i have not been able to finish anything bigger than a small print yet.

Please see if RCBugFix fixes the problem. Several of these strange behaviors have been fixed. You can download it here.

You'll need to transfer your machine specific items over to the new configuration files.

Do you have a filament sensor on your printer? I'm wondering if there's noise on that signal.

xspitfire commented 7 years ago

I will try the RCBugFix you suggested, Thank you

I do not have a filament sensor on the printer. With SD card printing the printer started moving to random positions (not on the print area) and back a few times before ejecting the filament.

@xspitfire

when you test make sure the sd card is formatted with https://www.sdcard.org/downloads/formatter_4/ first

pick format full overwrite and say yes to adjust format

strange things can happen to sd cards even thou you think they are ok

fbarcenas commented 7 years ago

All problems with the last RCBUgFix is fixed now, i think than we must close this.
