thunder laser controller DF211 goes haywire

Hi
yesterday I turn on my converted K40 and the thunder controller DF211 goes haywire.
the day before it worked perfect and then it does everythings like there own mind. the home position is overshooting to the lower right even if it should be upper left, nothing could change this not reset or new load of manufacturer settings. turn off and on did not help ether. then I set the manufacturer settings to the lower right and then it goes to the upper left. checked the limit switches all OK . format the controller memory . reload the manufacturer settings and finally it worked again but what a surprice I load the first job what I did a few days ago and I did not trust my eyes it engraved mirrored .
I reloaded the file but still mirrored the I took another file load them and it did give the same result .
now I am out of Ideas how to fix this.
maybe some one has a solution
thanks
and happy easter

There are a few ways to change the direction:
- swap two wires (A+ - A- or B+ and B-) of the stepper.
- change the dir wires to the stepperdriver
- change the polarity in the manufacturer setting in PHCad.

You just have to see for yourself which one works out for you.
Sometimes you have to do two of these..

Think also of swapping the wiring of you limit sensors when you change the direction of your motor.

ofcourse this is only for the mirrored axis.
