FAQs / laser crosshair setup?

« on: January 26, 2014, 01:15:10 AM »

I've seen a number of chrosshair lasers mounted on the CNC and seen them jog to the edge of there work piece. But what I'm looking for is the code and the button that once jogged to target I press and I get a GO X <some offset> Y <some offset> ADD tool Radius and auto zero the DRO's.

FAQs / Re: Homing/Limits

Thanks for the reply that makes perfect sense. Now a follow on question: I can only assume that the soft limiits are in relation to the now zero / zero position and not the home position. So now do I need to have my work coordinate inside the soft limits area before toggling in on on the run screen? Soft limits set as .5 = min and 97.5 max for X axis and .5 = min and 51.5 max for Y axis. I'm also assuming I'd need to toggle soft limits off before REF home.

FAQs / Homing/Limits

« on: January 15, 2014, 02:52:48 PM »

Is there a way to home REF a CNC router table at X+ Y+ rather then the std. X- Y- location limit switch locations. I understand that machine coordinates would be in neg values. Trying this I get a homing/ limit min>max error when a try to ref. the machine.  The odd thing to is that the Y jog direction flips direction after REF axis. I'd assume I would set my limits a neg numbers as well. My table has a 98 inch X axis travel and a 52 inch Y axis. I'd like to park the gantry at the X+ Y+ location as it is out of the way in that corner of the shop. You can see the DIY router table on youtube just seach for "ShadeTreeCNC"   or a link http://www.youtube.com/user/ShadeTreeCNC any help would great!
