Move Machine to inside soft limits when Probe Basic on

Setting middle of table as home isn't advised in my opinion. This tends to be the desire of new cnc users for some reason but will present some complications down the road once you've started actually machining. It's always best to use 0 home at full movement of an axis, especially if you plan on taking advantage of mdi use. When you use g90 for motion in mdi with a transition it's will require an extra bit of head math. Just a suggestion, but no industrial machines use that centered method.

Last i worked with such machine was over 15 years ago, and that machine was very old, so i wonder the same thing when i read such requests.
Using any CAM from last 15-20 years will make the use of such machine impossible, pretty much, from the get go.

Ok, so at the moment I have it homing right hand side of X (i.e. moves table to left cutting to right to home), Front of Y (Y- table comes towards front, cutting to rear, to home), and Z (Z+ moves up to home).

The reason for the front homing is I was not comfortable reaching end of travel at the base of the Z upright. But happy to be dissuaded.

Home switches are located X right hand side, Y front, Z top.

So if this was to change, could you please document out the placement for the homing switches, and the values that should be applied? I believe that it needs to progress to rear and right for cutting purposes. Z I believe is correct orientation, but settings on the home, offset etc... I must admit, I have been confused.

For Z for example, is this 0 at the top and homing at the top??

Could you please provide some direction and numbers that would adjust and orientate effectively?

Thanks and appreciated.

Ok, so it should be 0 to max travel correct? And that means homing switch is on the left, table moving to the right. Allows for cutting moving from 0 to max travel. Y is confusing for me as I could not work this one out and have correct orientation on the screen. Z, homing was recommended for the top, correct? So how is this configured normally. Does anyone have an example config? Standard xyz mill.

Does not matter at all, it can be set in LinuxCNC however you have it and need it.

Yes, that is correct.

It depends on the machine. Most vmc's home table full front and right so tool changes occur with work/setups/rotary 4th axis etc clear of any ATC motion.
