General Mach Discussion / Re: How to zero "machine coordinates" of cnc with no switches of any kind using Mach
« on: February 16, 2013, 07:01:48 AM »
Thank you for your quick reply Tweakie.
I've tried what you suggested but unfortunately Mach still tries to cut beyond the physical dimensions of the device.
Let me try to explain what I want to achieve and tell me if is wrong...
I want to dig a hole with size of 400x600x-5mms into MDF that I am going to place on top of the aluminium working surface that has size of 800x480mms in order to be able always to place other pieces of MDF with measures of 400x600x18mms to the same position always which will let me optimize the process of cutting my models. However this seems to be impossible due to the missing end switches on my cnc.
How I can set up limits in mach3 for the axis and stop them of moving beyond certain coordinates so they don't hit always the machine when reach the end of their way? Is there such a set up for users that do not have end stopping switches?
