Hi all, i recently getting errors while printing.
My settings havent unchanged since i started printing about 2 months ago, but on last week i started getting errors like "echo cold extrustion pevented".
AFter seeming to had fixed it rewelding cables, after a couple days i started getting checksum mismatch errors at printer connection and also while printing.

^ those are the lines i get at printer connection ( printer moves on manual commmands  and seem working okay beside it)

but at times those errors start happening in large rows that head te program to crash shile printing.


I have no idea what could be the cause

    Since it worked before, you must have changed something. It could be that your receive cache buffer is set too big. In that caseyiu get frequent errors like this just from buffer overflow. So reduce it to 127 which works in most casesas this in nowadays the defaukt cachefor arduinobased firmware. In some cases 63 is required,

    cache setted to 127 since first prints, now shile printing, here and there i get like

    what looks weird is that pritner keep working as it should while all errors

  • RepetierRepetier
    Sure it continues to send and correct data - this is required if you get errors but that amount is not ok. So please try 63 byte buffer. 

    Did you upload a new firmware version so zhat changed something?
  • MARRA92MARRA92
    everything is with same setting it had at very sirst print, what i notice it happen more no larger prints but i dont know how that happen, for a better comprension i would like to see the issues separately for example:-
    - what cause "cold extrusion rpevented"
    -what cause checksum mismatch line swap
    -what cause buffer timeour

    further infos: first problems started after last update, might there be some kind of conflicts.
    Anything bad could happen if i lower the Cache value? or it can only help?
  • RepetierRepetier
    Reducing cache to 64 has no bad influence except speed a bit lower, but if then errors are goneit is faster as it then matches the firmware.

    Whatdidyou update?

    cold extrusion is extruding with no heaters on, the other errors are resolut from communcation problems.
