Lathe post problem

[Mgrenier]

Hello all,

 

I downloaded mplmaster from here and started customizing for our needs. Everything works perfectly for us except the Pattern repeat canned cycle (G73) . I get a double post for my tool end section but I do not know why.

 

Anybody have an idea?

 

Here is what the program looks like:

Attached is a Z2G of the file.

Looks like you've been doing a little post editing in the ptoolend$ post block!

 

This is a function of the pattern repeat cycle that is passing through the ptoolend$ post block twice per operation with a null toolchange. The nci file gives the post this direction.

 

You need to add logic in the ptoolend$ post block to look after the repeat instances. I would suggest using op_id$ to try and limit the output in ptoolend$. A quick test has this get the correct output, though it may need to be a little more sophisticated to deal with the specific operation type rather than all operations.

 

       else, #Null toolchange
         [
         if op_id$ = prv_op_id$, 
           [
           #if n1_posttype <> posttype$, pcan1, pbld, n$, pnullstop, strcantext, e$
           pbld, n$, *sall_cool_off, e$
           pbld, n$, pnullstop, strcantext, e$
           coolant_on = zero
           toolno = t$ * 100
           if home_type = -1,
             [
             prv_gcode$ = c9k
             #pbld, n$, `sgcode, toolno, e$
             pbld, n$, "G00", "T0100", "U0.", "W0.", e$
             ]
           else, pbld, n$, "G00", *toolno, "U0.", "W0.", e$
           else, pbld, n$, "G00", "T0100", "U0.", "W0.", e$
           pbld, n$, "M01", e$
           ]
         !op_id$
         ]
