@ marqcnc, You've bought a IEKH machine?
One of my friends had the same problem. Are you sure you've set the right settings (like enc steps) etc. With the machine of my friend they didn't. I had o figure it all out for him. If you have the IEKH machine, I attached some info which could be helpfull.
Also, make sure the cable of the PC to the machine is well attached, I found some problems with it before. But ofcourse, if all of the limits are red...?
Last: in the (I think) third menu all to the bottom is something like "overide limits" when you click it it will open a window. As long as you keep this window opened, it ignores the limit switches.
Good luck with it! I hope you get better Chinese support then we did
