[ponte]

I have got a used Laser machine HY-690 ºêÔ¶¼¤¹â ¼¤¹â ¼¤¹âµñ¿Ì»ú ¼¤¹âÇиî»ú ¿ÌÕ»ú ÁijÇÊж«²ý¸®ÇøºêÔ¶¼¤¹âÉè± ¸ÓÐÏÞ¹«Ë¾-ÍøÕ¾Ê×Ò³
I have problems with installing driver/software (RDcam 3.0 no idea about Mainboard) I assumed a mainboard-USB communication problems.(which not detect driver)
I changed mainboard /control panel MPC6515 and installed lasercut 5.3 communicate Okay with PC can download config.

But we have got problem with Y axis that moving wrong direction control panel and lasercut either wrong.
I tried switching wires U,Vand W on Y axis stepper motor drive but no luck.
Do i need change software syscfg.ini that Im guessing stepper motor mounts opposite way?!

Thanks

No , you do not need .
Change the position of A+A- OR B+B- on y axis driver .I mean the wires position . Then power on and test you will see .
