MKS base v1.3 stopping mid print

Hi Guys,
I have a Prusa I3 with MKS base v1.3 and I have a problem that it stopped 3 times mid print on my last print for no reason.
The temp stays at 190 so the board is still active but the job just sits there and melts into the stationary hot end.
The last 3 times it stopped it was in exactly the same spot on the print so I was wondering if it could be the STL file.
Strange thing is that the same file printed fine on my spare printer which uses a ramps setup.
I am using a 5:1 geared extruder on the I3 so the extruder stepper motor has to spin 5 times what a normal motor would so I was also thinking that it might be overheating the extruder stepper driver chip causing a shutdown (although the fact it stopped 3 times in exactly the same spot is odd).
Does anyone know if this is a feature that the MKS base v1.3 has?
If it does have an overheat / shutdown feature then should I heatsink the stepper driver chip?
Could it just be the STL file which looks fine to me?
Any help would be great.
Thanks
Mike

3 time in the same spot, most likely some gcode instruction that you firmware do not like.

I think when an stepper overheat it will stop only is motor and not all board.

You can check the z position where the print fails and check if there are some strange or diferent gcode in the file.

HI,
Thanks, i will take a look. I had a quick look at the code already but couldn't see a problem. I will report back if anything suspicious shows up.
Regards
Mike

What firmware are you running?

Hi All,

I think I resolved the issue, I think it was the SD card. I think it must have had a bad sector or something, I used a new card and the print completed.

Hi DC42, the firmware is Marlin.

Thanks guys for the help.
