3D Printer has stopped running the desired G-Code

Nexus

Just recently, my 3D Printer has oddly stopped executing the desired G-Code, despite, according to the Repetier-Host, is printing.
On the Host, it surprisingly goes through the print, except a lot faster than how you normally would print.
While on the printer, nothing is happening.
Details:

OS: macOS Sierra
Baud Rate: 234000
Stop Bits: 1
Parity: None
Transfer Protocol: Autodetect
Receive Cache Size: 63s
Timeout: 40s

Thanks, and I appreciate your help.

Sounds like firmware had detected a severe error and starts to ignore following commands You should see that in the log if enabled.

How do I fix an error of this magnitude?

Where do I start?

I tried re-installing repeater host on my Mac and also re-installed the fo=Irmware on my da Vinci 1.0a - made no difference at all.

Thanks so much in advanced.

Start with logging enabled and see what firmware tells you why it stops. Then fix the problem mentioned.

This is what the error log says...

< 2:06:19 PM: Unknown command:N85 M107 

< 2:06:19 PM: TargetExtr 0:200

< 2:06:19 PM: SelectExtruder:0

< 2:06:25 PM: x3

< 2:06:25 PM: TargetExtr 0:200

it then shows x3 quite a lot

then this appears:

< 2:07:35 PM: Unknown command:N933 M106  S249

a bunch of x3 again then ends with:

< 2:08:00 PM: Unknown command:N5927 M107 

< 2:08:00 PM: TargetExtr 0: 0

< 2:08:00 PM: SelectExtruder:0

< 2:08:00 PM: TargetExtr 0: 0

< 2:08:00 PM: x3

I still can't decipher what the error is.

I really appreciate your help.

Thanks.

Because these are no errors M106/M107 are fan control commands. If you have no fan support these commands are unknown. So that is a harmless issue to use unknown command.

x3 is nothing that should be shown. What version are you using? You could search "x3" and delete the line most probably. I guess it is a forgotten debug message somewhere.

What you search is a line starting with Error: at the time printing stops and commands run faster through.

This is all it says at the start of "print"... problem is nothing happens in the printer itself. The commands just start running.

I cannot see any obvious error on any line.

Your thoughts are greatly appreciated.

Thanks.

I've noticed something in the Command Outputs that may lead to the solution of this problem;
The X, Y, and Z values aren't changing. Only the "E" value.

Repetier

In deed i see positions stay so i wonder what the gcode looks like. Should be identical to commands send so this gcode would not plan to print and since no xy moves are there it will be very fast. So next step would be checking the gcode - should display in host and get printed simila6r to visualzation.

Nexus

Codes generated by Slic3r looks good. However, once executed executed and displayed on the log, the xyz values look as above.
I tried printing from SD card with same results.

I have successfully fixed the problem by reinstalling Repetier Firmware.
Thanks for your thoughts and help!
