Corrupted Prints

edited April 3 in Bug Reports
Every now and then my prints get corrupted, varies but usually I have to reinstall the Pi Deb install to resolve then ok till the next time. 
It’s not the GCODE because when I use the same GCODE after reinstall all is ok.
v0.94.3.
Prusa MK3S 

I can tell there will be a corruption as soon as the first layer starts printing, very fas 1st perimeter then prints a diagonal line from corner to corner, then.... see photo.

    Hi, I have got exactly the same problem. I have run Repetier for a while now and this problem begins last week for me. I have MK3S+ and have checked my belts, I have clean and re-greased all moving parts, I have run belt check on printers and of course was everything perfect. At last I was able to connected to my brain and tested a print from SD card and the print was perfect. So after that I was sure that the problem are not the printer and found this Bug reports and hopefully some more gifted than me can finding out the problem with Repetier-server and this bad prints

    I’ve had this problem randomly for a few months, last time this cropped up was a few weeks ago. Just a restart sorted that. Usually that’s all it needs. This time only thing that worked was a reinstall of the DEB.... initially I thought is was me not shutting down the Repetier properly before turning off my MK3s, or disconnecting the power accidentally. May these were issues but this last time I’m 99% sure I shut down Repetier properly last night. Not a massive problem for me as long as it doesn’t keep happening.

    You should upgrade to 1.0.4 for all the fixes being made. Not really sure what is going wrong here - looks a bit like under extrusion but for some moves it seems extrusion misses completely. Maybe not switched to relative extrusion while print is. Ever tried just deactivate and activate to reinit connection and start commands send to printer. At least one of the in between versions had the problem that sometimes a line at startup was not send in some connection combinations.

    Ok I’ll try updating again.... I haven’t tried deactivate and reactivate, I’ll try if I have problem after update. If I get it again I’ll video the print.

    Thanks

    Hi NickRno77
    Which FW version are you running on your MK3S? I am running version 3.10.0-RC1

    Hi NickRno77
    Which FW version are you running on your MK3S? I am running version 3.10.0-RC1

    //Patrick
    I’m running V3.9.3 latest, Not RC. Slightly tweaked for Prusa Mk3s Bear 
  • RepetierRepetier
    I'm running many prints lately on my prusa mk3s with original 3.9.3 without problems. I guess if it happens one special setting got wrong somehow, also I have no idea which could cause such prints.
  • PGe68PGe68
    I have two MK3S and one MK3S +, I run MK3S on FW 3.9.3 and I run MK3S + with FW 3.10.0-RC1 and all three printers have the same error. I tried last night to reInstall Repetier-Server with Image V25 (1.0.4) on a new RPi 4 4GB, new 32GB SD card and a brand new RPi USB-C Power supply and another USB cable (Not "factory" new) but the same error on the printout remains.
    I connected my OctoPrint to MK3s +, printed the same Gcode perfectly, also from SD card it is perfect, so I "dare" to say that the error is in the Repetier-Server direction .........

    Greetings, Patrick

    Could it be your Repetier Printer Prusa settings? 

    Is be interested to see a video of the problem.

    Try activating ping-pong. Than print order is same as in OctoPrint. Otherwise server will try command sin parallel and with bad input buffer size that can cause problems, but these normally get fixed. But would not be the only printer requiring ping pong.
  • PGe68PGe68
    Hi, I'm been following your advice on activating ping-pong and now it seems to be working fine again. I have tried to print the same Gcode that failed and it looks good
    I have no idea what ping-pong really is / does but it looks like it works for my MK3S printers with this enabled
    Thanks for the help, I really appreciate it because Repetier fits my way of using my printers, better than I think OctoPrint does. In fact, I do not think that you can really compare OctoPrint with Repetier-Server because they are good in different ways

    Good to hear that worked although mine is fine now? Where is this setting for activating Ping-Pong

  • RepetierRepetier
    In communication settings of printer in server.

    My ping pong is not set on, If I get problems again  I’ll switch it on.
