everything worked fine for day one. then day 2 the x axis is now backwards where I use move function with the left arrow and moves in the negatives coordinates but it moves to the laser to the right on my 3d printer. at startup sometimes it will say hard limit triggered other times it will not and say homing ok. I wrote an email for support and didnt really get an answer. (watch this video it should help) thats what ive been doing for the last couple of days was reading forums and watching whatever I can to see whats been messed up. I can’t even use with the memory card offline it wont preview or do anything offline either. when I set up the controller I used the automatic search and GRBL-M3 came up so I chose that one. The workspace is set correctly @ 300x300 start position is front left or 0,0 if you will. this is a screenshot of the $$ menu.

when I hit move function right it hits the limit switch because it moves left instead of right and it tells me to rehome the laser but I cannot find a way to do that anywhere. I assume the limit switched are supposed to do that but idk.

      I believe I figured it out at least for now. As I did more research onto the problem I looked closer at the edit machine settings. Even though I inverted the axis’s for movement I still had to invert them for homing as well. Basically I inverted X axis ($3) and it threw the Y direction axis and homing for x out of whack. Therefore I changed (inverted) x axis homing ($23). It homed to the right corner (front left) but unfortunately It still did nothing as the Y axis direction backwards now. Obviously the pattern is the same as with the x axis if you change one you need to change the homing as well. Therefore changed both Y direction and Y homing invert (also $3, and $23 respectively). The final numbers were for me $3=7 and $23=3. I did find it easier under the output setting under machine settings in the edit tab to change the settings. The other thing of note and I’m not sure why is any of the previous files I’ve saved and attempt to use will screw up like prior. Although the settings are still changed when I look at the settings on the controller. Also, Thank you for your help Wyked.
