Thanks Hood
I dont know how you would use a single switch in the centre but anyway, so you could wire up 8 switches, 4 for x, 2 for y and 2? for Z (<---Linked) and then how would you the use those same switches for home?
Thanks

General Mach Discussion / How many limit switches

HI
I am just a little confused as to how many limit switches?
Do you put 4 on the X axis? either side and at each end?
plus 2 on the Y
And 1 one the Z?
And do you add home switches on top of that?
Or do you just have 3 limit switches and they act as home switches aswell?

Thanks
Chris

General Mach Discussion / Re: Machine Limits without limit switches? to stop me crashing

Thanks guys, i will look into limit switches.

Another silly question i have is,

I have everything set and homed, now if i move the gantry up to the material and zero it out and run the gcode, when its finished and i hit return to zero it returns to where i zero'd it out not to the home back in its corner, the only way i can get it to do it is to close the program and open it again and the hit return to zero and it goes back to its corner?

i am sure its something simple i am missing
Thanks
Chris

Hi Guys
I am new to this, I have watched the video on homing and limits but its talking about the use of limit switches and i dont have limit switches, i am sorry if this question has been asked a thousand times, i have been searching for a while and playing round in Mach 3, i just want to understand how to set up limits without limit swithces so it doesnt crash into the ends?
Thanks
Chris
