At first, i apologize for my poor English.
I use Smoothieboard to print 3D model. Just now, i meet a problem that the extruder reversed suddenly while ptinting a file in the SD card. i think it one of the "G92 E0" code does not work well. It seem that the value of E didn‘t turn into 0. When meet the next code like "G01 X10 Y10 Z10 E10", the extruder thought itself should go back to 10 from a some large value. What should i do？
Hey. It could just be a reading error on your SD card or a communication error when you sent it, maybe try formatting the card and trying again.
I tried by this method, but it didn't work.
This is the part where causes the problem

the extruder reversed when ran into line 32741.
I tried to generate the slice file by another engine in repetierhost, and works property, the Code “G92 E0” apper in every interval like this

also, i tried by Cura to generate the file, the file has no "G92 E0", and works well too.
did i miss something?
One thing i forgot to note that online printing by repetierhost is OK
What generated the gcode that causes a problem ?
The gcode looks clean … does it do it on every file you slice or is it just one file ?
Two files . It is the first time i had printed such a big file. It seems that the extruder can not be set to 0 by "G92" when larger than 10000 or some value.
These faulty files were generated by repetier host with CuraEngine. But using Slice3c could sovle the problem
Is the problem related to my configurations?
Hi, I am very grateful for your help. And feel sorry for that I caught the mismatched bug.
The problem does not exist in handling "G92", but the gibberish in the gcode.
Here is the erroneous gcode :
G0 f6000 ر9.844 Y-36.864
G1 F3600 X20.479 Y-36.v29 Ÿ761.11155
G0 F6000 Z33.386 Y-36.865
G1 F3600 X34.021 Y-3v.229 E876!.13391
I am still looking for the causes, If I solve the problem, I will upload the details.
Your SD card got corrupted, you need to format it.
I don't think so, because the original file saved in my PC are same.
Here is another of the two wrong file:

Then your harddrive is corrupted, or something similar to that.
