Hi,I've started receiving these errors in my log on Repetier Host as soon as I click on print, which stop all communications, and don't let the printer proceed.Here are the errors I'm getting: 21:23:27.040 : Resend: 16

21:23:27.094 : Resend: 16 I'm using Marlin firmware on Repetier Host V2.0.5 (the latest). I tried it on the old one too, but I got the same results. The Marlin firmware is the latest, 1.1.I have tried different slicers, and all of them lead to these errors when I click on print.Can someone please tell me what could be going wrong? I don't know what the error means.Thanks a lot:)

Answer is most probably in line 15 or 16. Please show a full log with commands and answers from firmware.

Hi,
I tried printing the exact same thing, with the exact same G-code twice, and i got two different errors each time, concerning different lines. I don't know what's going on, because it's the same thing i tried to print. This is what i got when I clicked on print for the first time after slicing it with slic3r:

And this is what I got the second time:

And it stops all communications. I'm sorry, I'm a beginner at this, but this is what you asked for, if i understood correctly. Please tell me if it's not and how to get the full log.Do I need to show you the G-code?I get similar errors when I click on print after slicing it with Cura.

First M999 should be send after firmware stops for a severe error, So I wonder why it is there? any errors you did not mention?Then M110 resets line counter to 1 which is ignored by firmware and it wants to continue with line 33 so it did not see the N1 M110 line. So solution is fixing the reason M999 was send, then you can ignore why firmware does not accepts M110.

Hi,
Thanks a lot, I found that the error was being generated by the printer settings in the scripts tab. Somehow, a "M999" got registered in the start code. I erased that and everything worked fine.
Thanks again:)
