Communication timeout - reset send buffer block

[TVarius]

I have had this i3 X printer for over a year now and all of a sudden when I print, itll stop midway and show a communication timeout error in rep host log and says "card removed" on LCD, suggestions? I have already tried reflashing firmware, trying different cables and printing directly from the SD card and when I print from SD card it just stops what its doing and says "card removed"

Hi
I had a similar case, but the problem was that I tried a different type of connection.
When I restored communication via COM port not all settings were returned as before.

Currently having the same issue, causes the whole printer to disconnect anywhere from 5 minutes in to an hour in and unable to resume a print. Really confused on what could be causing the problem

I get a similar error.

I have a 3-in-1 controller box with the GT2560 control board in it. I've been using the printer (Repetier and Slic3r) )with no problems for over 2 years. All of a sudden, as of 3 days ago, I get the problem: printer just stops in the middle of a print. Sometimes it happens on the 1st or 2nd layer, sometimes 100+layers into the print.

If I'm printing from Repetier Host, I get "Communication timeout - reset send buffer block"

When I go to check on the print, everything is stopped, heaters are off, extruder is stuck to the part.

I've tried printing directly from SD card, and still get the same stoppage. This tells me it it's not a PC, Windows driver, Repetier or Slic3er issue. Looks like the communication timeout originates on the control board itself.

Not sure what to do about it. It's really annoying. Everything has been working flawlessly for 2+years, and I have parts I need to print.

I finally just said screw it and replaced the controller board with a new upgraded board and its still occuring

from what I have found, mismatched baud rates can cause this, in case that helps any of you above. I am currently retesting with matched baud rates since I changed my controller board its gone to COM4 instead of COM3 so im not sure if it was mismatched before or not.
