Author Topic: Would like to add in a certain path for toolchange to run. Need Help  (Read 5469 times)

0 Members and 1 Guest are viewing this topic.

I would like for the machine, once the tool-change is initiated, to take a certain path ( z to 0.0 then x to 0.0 and y to 0.0) then move along y 0.0 to the tools x position, then proceed with the normal tool change. Once tool is released, the it would go back to z 0.0 and then move to y 0.0 and move along y 0 to the new tools position and proceed with tool change.

From what it looks like the tool change macro from the tutorial moves over other tools. I don't have the clearance necessary to do that so hence I need the machine to back off to y 0.0 and select the x for the new tool then move in directly so as not to hit another tool.

Any help would be appreciated.

Well So far I have figured out myself how to get x to go to zero and then y zero before making tool change. I now would like to place in a code for pulling up old x pos and going to it first then to y pos separately. Then same thing for going to the new tool. I want it to go this way because of tool clearances are non existent at the tool changer area. Any Ideas?

Would I need to make A sub for oldtool x and oldtool y in-order to separate them so the machine moves in the pattern I want. I guess same for the Newtool.

Define the positions like the sample macro does, and assign them to variables. Then just use G0 moves to move the machine where you want.
Code "G53 G0 Xold"
Code "G53 G0 Y"

Here is what I got so far Gerry the changes are in red. What you posted is exactly what I had in mind. I am new to scripting so where and how do I put the definition in. The attached picture is for a little better clarification.

The reason I want it to go a specific way is because if the operator knows the tool change routine is about to happen and it does not move in a specific way, he then knows there is something funky going on and needs to reboot. I am working on it but it is just added to a long list of things to do :).

We have really bad power fluctuations and it affects the computers every know and again.

When you do:

Call MovePos(OldTool)
While IsMoving()
Wend


It will move to the positions specified in this section:

Select Case ToolNumber
       Case Is = 1
         Xpos = 12.00
         YPos = 2.00
       Case Is = 2
         Xpos = 14.00
         YPos = 2.00
       Case Is = 3
         Xpos = 16.00
         YPos = 2.00
       Case Is = 4
         Xpos = 18.00
         YPos = 2.00
       Case Is = 5
         Xpos = 12.00
         YPos = 2.00
       Case Is = 6
         Xpos = 14.00
         YPos = 2.00
       Case Is = 7
         Xpos = 16.00
         YPos = 2.00
       Case Is = 8
         Xpos = 18.00
         YPos = 2.00
End Select





With this line:
Code "G53 X" & XPos & " Y" & YPos

You'll probably need to add some additional moves in there to get it to go exactly where you want it to.

So is this what you are saying,

Select Case ToolNumber

    Case Is = 1
      Xpos = 12.00
      Ypos = 2.00
      Code "G53 X" & XPos & " Y" & YPos

or would I take out the coordinates and place in xpos and ypos in the code you posted and just have a code for the Case Is = 1

I know how to get it to move separately, so I will just adjust the code accordingly. Knowing where to put it to get it to do what I want is the hard part.

If I need to remove the xpos and ypos then I think I need it to look like this

Case Is = 1
   Code "G53 X" & 12.00
   While IsMoving()
   Wend
   Code "G53 Y" & 2.00
   While IsMoving()
   Wend

Just change this:
Code "G53 X" & XPos & " Y" & YPos

To this:

Code "G53 X" & XPos
Code "G53 Y" & YPos
