Variable Z feed

[CADin & CAMin]

I have two machines that have different z feed speed requirements, when I do not ramp. The controlers will do math and can use variables. If I have a linear move that is only a Z move, I want to include a multiplication to the feed. This is the code I have tried. It does not work when there is only a Z move.

 

Can anyone help me fix this code or give me a better way to do this?

 

Thanks in advance.

if (xabs<>prv_xabs) | (yabs<>prv_yabs),

[

pcan1, pbld, `sgcode, sgabsinc,

pxout, pyout, pzout,

pcout, feed, strcantext, e

]

else,

if zabs<>prv_zabs,

[

pcan1, pbld, `sgcode, sgabsinc,

pzout, pcout, *feed, "*V23",

strcantext, e

prv_feed = -9999

]

I'd set this for starters - prv_feed=c9k

 

I'm a bit confused by the "*V23". Is this what you want to come out in the code? or are you trying to perform a calculation based on that value?

 

Have you ocntacted your reseller? I'm sure they'd be more than happy to assist you.

Thanks for your reply James.

 

In the opening of my g-code I have two intialization sections, one for each of the two machines we have. Part of this section sets variables specific to the machine. The V23 is a variable factor to calculate the different z speeds.

 

My reseller in Huntington Beach is very knowledgeable and has been helpful when I have ocntacted them. My problem is that I almost never have time to work on my post processor during the day.

 

Thanks, Bert

Hey Bert.

 

Use the motst variable:

 

motst = 4 if Z only motion.

 

if motst <> 4,

[

pcan1, pbld, `sgcode, sgabsinc,

pxout, pyout, pzout,

pcout, feed, strcantext, e

]

else,

[

pcan1, pbld, `sgcode, sgabsinc,

pzout, pcout, *feed, "*V23",

strcantext, e

prv_feed = -9999

]

 

Your code looks OK except that you have:

 

else,

if...

[

.

.

]

 

the nested if has to be inside [ ]'s

 

Have fun!
