Newbee my next step is to install limit switches on my shopbot . just finished building my controller have not hooked up for testing as yet.
i want to use micro switches as my limit switches. what i am thinking of doing is just mounting three switches on the y carriage
one for x y and z.
and use operating ramps to trigger switches at both ends or x and y.
have anyone used this system, without a problem?
also what brand of microswitches is recommended and where can they be bought.
a part number would help.
i notice there are some with a long lever and some with the lever in about the centre of the switch.
Is is possible to run mach3 in demo mode and assimilate the limit switches position?
or must the switches be physically struck.
eg can this be done in demo?
With the home switches wired and tested it’s time to home the machine. With the control out
of E-Stop mode, go to the Program Run screen and with one hand on the E-stop button press
the Ref All – Home button. The machine will now start to move Z up until it hits the switch
then it will reverse the axis until it clears it. Then it does the same with the Y-axis and finally
with the X-axis. When each axis is homed the DRO’s should read 0.00 or whatever value you
put in as the Home Off value. If any axis starts to move in the wrong direction press the EStop
button and go to the Home/Limits setup and change the Home Neg setting for that axis.
