Strange problem

[regpye]

Is the direction that they now only move in the same direction as they move when homing?

It may just be that the settings are all screwed until it completes a homing cycle correctly. e.g the machine thinks its in some stupid position, and will only move towards it's expected correct range. Maybe X thinks its at -1000 and knows its only allowed to be -500 to +500, so will only move +ve until it thinks it reaches -500.

First thing to try is disabling soft limits. That should prevent the system babysitting your positioning.

I am able to travel positive and negative until I do a homing. The homing is travelling in the negative direction. After homing I can travel only in positive directions, regardless of which direction I choose.
I checked the wiring this morning and found that the Y axis limit was badly connected. This caused the homing fail. I fixed that and was able to home successfully after that, but the X and Y will still only travel in the positive direction, even if I select negative travel.
I disabled homing and soft limits, and tried again after resetting the computer and the machine.
After manually positioning the tool in the home position and setting zero X and Y, I am able to move in both directions no problem. But setting the travel lengths to the numbers shown on the screen, I am able to travel and stop in the correct positions and using the home button, return to the zero X Y that I set.
Once I turn on homing the problem starts again, so it must be something to do with the homing setup I think. I checked the limit switches and they are all OK now.
The homing direction is correct for my machine, but maybe it isn't?? I am homing to the front lefthand corner.
