Problem with a post...

[JAMMAN]

I'm playing with a custom post for an anilam crusader M controller. Evidently the previous owner of the machine never had the ocasion to cut anything with an arc...

 

I can edit the prog manually and get it to work. Heres a snip of the output code:

N0170Y2.6324F20.0

N0172G2X-1.905Y1.6324I-2.905J1.6324

N0174G1Y0.6326

N0176G3X-1.405Y0.1326I-1.405J0.6326

N0178G1X-1.2285

N0180Y-1.3326

N0182G3X-0.4285Y-2.1326I-0.4285J-1.3326

N0184G1X0.8175

N0186G3Y0.0424I0.8175J-1.0451

N0188G1X0.5215

N0190Y1.5126

N0192G3X-0.0985Y2.1326I-0.0985J1.5126

N0194G1X-1.405

 

Everything is ok till line 186 then the controller gags and can't convert it to the anilam equiv. Here's what it's looking for-

 

N0184G1X0.8175

N0186G3X0.8175Y0.0424I0.8175J-1.0451

N0188G1X0.5215

 

The X start position has to be in the arc code for the controller to convert it properly. I've tested it and it does work.

 

How do I force the arc to output the start position (X and Y)all the time?

I just finished a 3D gramming job for a guy with one of those. What a pain no arcs allowed I used the CD defalt MPAN5300 pst and forced all arcs to linier in the filtering and everything worked out

Change this;

 

code:

---

pcirout1        #Output to NC of circular interpolation

pcan1, pbld, n, `sgfeed, sgplane, sgcode, sgabsinc, pccdia,

pxout, pyout, pzout, pcout, parc, feed, strcantext, scoolant, e

---

to this;

code:

---

pcirout1        #Output to NC of circular interpolation

pcan1, pbld, n, `sgfeed, sgplane, sgcode, sgabsinc, pccdia,

pfxout, pfyout, pfzout, pcout, parc, feed, strcantext, scoolant, e

Trying it now...thanks!

[JAMMAN]

OK No such code! Here is the closest to that I can find...

 

pcirm # Circular interpolation

pcan

n, sgplane, e

n, sccomp, e

pcan1, n, sgcode, x, y, z, pijk, pfr, strcantext, e

pcan2

n, e

Fixed it, sort of. Break arcs into quadrants. It only did it on 180 degree arcs where the x end was the same as x start. Or y start equals y end. Seems to be fine now!

Add the "*" (asterisks) to to varaibles you want "forced" out.

 

code:

---

pcirm # Circular interpolation 

pcan

n, sgplane, e

n, sccomp, e

pcan1, n, sgcode, *x, *y, z, pijk, pfr, strcantext, e

pcan2

n, e

Note that if this machine can do arcs in the XZ or YZ plane, you've got a problem with this PST code - since it will always force X & Y to output on every arc motion block.

Thank you again, Roger. You have helped me out many times throughout the last few years, especially in the Axsys days.
