Stop 4th axis from going home, EC400

[34ford]

I need to get the tombstone to turn 90' and then stay there till I can drill, countersink, and tap with it in that position.

I managed to get the tombstone to turn with a A90, and drill. But when it gets through with that drill and goes to get the next tool the G28 makes it go back to 0.

There has to be a way to get it to stay till I tell it A0.?

Eliminate the A0. from the G28 line.

Is it the tool change program that makes the G28 ?
When you program M6 ?

[34ford]

Oh I forgot to mention, there is no A0 or any A codes in my post at all.

I have to place the A codes in manually. This old Teksoft dont do it for me.

So what I did was put the A90 in the line with the G57 and that was all.
I assumed it would stay at that position till I put A0 and the end of my program.

Do not use G28. There are other methods to position clearance in Z.

Time to break out the manual; G28 sends all axis to the home position.

When you use G28 as below, it only sends the listed axis's home.

G00 G91 G28 Z0.;

Per this example, only Z would return to home as in a tool change.

I agree 100% but I suspect that he is using just G28 by itself. My intent was to encourage him to look up how to use G28 properly.

Perhaps maybe he could post part of his code?

Dang, messed you up, want me to edit it?

Thats the way Teksoft does just before each tool change, which works, just not now that I wanna keep this axis to stay put.
I will take the G28's out tomorrow and see how it works.

Teksoft may be trying to clear everything out of the way for a tool change, so just make sure nothing is in the way for a tool change.

Yea, I will definitely make sure the tombstone is back first.

Oh something I just thought of too. Teksoft always puts a Z0 at the end of each op and boy that is a disaster on a EC400.

Feeds the tombstone into the spindle!

Sounds like you should ask for a different post processor.
