Printer crashing to the right  

Printer crashing to the right

This began happening after i wiped my computer, and started printing with a newer version of the slicer, not sure if this is related.

What happens

The printer goes through bed leveling and will "get stuck"  it also becomes less rapid as it goes along with the leveling moving up and down more slowly in some spots.  sometimes on the 4th spot it tries to level then just goes straight into printing. sometimes it does not.  What it has been doing continuously is loosing its position in i believe in X, and trying to run x off the bed.  It jumps immediately from spot 4 to trying to print the dump line off that position.  I do nto ahve the latest firmware installed, this could be related.  

I have another prusa with different firmware it has a bondus extruder and a mosquito magnum hot end but does not do this.  I can upgrade the firmware, but is there something else that is doing this?
