Printer no longer reading cura generated gcode


Recommended Posts

Posted (edited) · Printer no longer reading cura generated gcode

Hi,

 

This is a software question. I've been using Cura for my Anycubic I3 mega for about 2 weeks, and it had been working fine. Today, I was trying to print a new file that I generated from Cura, and it just wouldn't print. So, I re-rote the gcode, and tried it again. nothing. It doesn't even start warming the bed or the nozzle. I tested some old gcode and it printed just fine. So, I tried testing out a different model. I downloaded a Benchy from Thingiverse, put it in Cura, exported it into gcode. still nothing. I then uninstalled Cura, and installed an updated version. I put in new printer settings. Exported Benchy again, and still nothing. I tried a different SD card even, and that didn't work. I've also restarted my computer several times out of desperation. I'm at a loss at this point. Any suggestions? I've attached a screen capture of my setting for reference.

    Hi and welcome to the forums.

     

    Did you compare the old (and working) .gcode files and the newly generated one? Do the headers look different or are there any missing commands for heating up the nozzle?

    When you say "nothing happens" - does the printer not react at all when you start the print or does it skip right to the end of print routine and possibly homes the head? Admitedly I know nothing about your printer hardware but since you are familiar with it, you can judge if the printer can't read the .gcode file or if something simmilar happens.

     

    Have you tried to create an empty .gcode file and start to print it? Does the printer behave the same as with the newly generated (and not working) .gcode files?

    There are several gcode readers available. You could load the non working .gcode files and see if the print preview works. Personally I am using the IdeaMaker software as my default gcode viewer on the Mac (because it starts faster than Cura and doesn't mess with the Cura settings if I am currently working with it).

    Hi Nicolinux, thanks for the response. I just put the .gcode into a reader, and can't see a difference. I attached an image incase someone who know more about it than me can spot a problem. The code on the left doesn't work, and the one on the right works fine. 

     

    By "nothing happens" basically, I press print, and the printing screen comes on, however, nothing changes. It doesn't home or heat up. It just sits there. Then when I hit stop on the machine, it says stop command has failed. I have to manually turn of the printer in order to do anything. 

     

    I'm not sure how to generate an empty .gcode but I'm happy to try if I can figure out how to write one.

    Okay, so I don't think it's the gcode. I'm pretty convinced it's the SD card. Still not sure how to fix it though. I can't get any new files I put on the card to be read properly by the printer. It won't even read the original gcode test "owl pair.gcode" that came with the printer. The issue now is I can't get a new SD card to read either. I'm not sure if there is a formatting process for the card or what. Anyone have advice on this? Thanks!

    My issue turned out to be the formatting on the SD card. The first card was corrupted and the second one wasn't formatted correctly. Reformatting solved it, but it took a lot of trouble shooting to get there. Hope that helps!

    Same here. Files were shown, but once selected and started nothing happened. Bed temperature stayed at 0. Old gcode files worked fine. I backed up files form the SD card and formatted it using FAT with Mac Disk Utility, ran Cura again, saved to the newly formatted SD card and now it works again. Thanks for sharing. Saved a lot of time.

    This was my issue. I spent weeks trying to figure this out. I thought it had something to do with the latest version of Cura, since all the old files on the SD card were working. Nope. Just had to back it all up, and format the card. Thank you!!

    Ok so here's the deal. I don't think it's the SD card or the Printer. I was using Cura with Anycubic I3 Mega, it worked beautifully for nearly 6 months, then I upgraded my Cura software and bam! Every print I tried vis SDCard or USB Connection, the printer freezes every sing time the print starts. So for months I tried reverting to an older version of Cura, Nothing, replacing SD Card and the reader, I even swapped the mainboard. None of it worked. Then last week I tried installing Meshlab and low and behold with a USB cable the anycubic began printing again. Only problem being is that I had to install the anycubic manually so the bed doesn't line up with the program so the prints run off the bed. 

     

    The point? It's a problem with Cura not the Printer. I don't know how to fix my bed alignment issue yet but I thought I'd share what I've learned so far. If anyone has the answer for me I'd appreciate it.

     

    Thanks.

    Hi to all.

    I had the problem where the printer was not showing any files at all. I fixed it by using the program called " SD CARD FORMATER " from sd associations (free download from the internet).

    Just to mention that windows formatter did not fix the problem.

    I hope these informations would be usefull.
