You will need to calibrate it to get the correct value.

The configuration looks OK, except the 158 for the E axis seems high. That shouldn't effect the X axis though. Maybe the belt is too loose, or there is a problem with the stepper driver? There is a way to test the voltage, it's on the forum here somewhere. You can also swap out the stepper driver wi...

Is the X belt slipping? Problem with the servo? Settings issue with the travel speed? That's a strange problem.

Can you attach the GCode file so I can try it?

Check your thermistor. It sounds like it has slipped out of the block a little bit. I had the same issue.

Not normal behavior. My default is 60mm/sec and I have no problems.

No. Those are for an auto-leveling sensor like the 3D Touch.

Try this. You will need to change your sensor offsets and probably a few other things since I'm using a Pro C instead. I also included the pins configuration file for the 3D Touch. The configuration.h files will not work with the current official, stable release of Marlin or with RC8. I believe it w...

The touch sensor Z stop is polarity sensitive. Make sure it's wired correctly. You can also check the file here for exact instructions on fixing Pins.h

Is the Pins.h file set up correctly?
