I think its a cutter comp problem.. as in small moves and large comp value

how much cutter comp have you got on this toolpath..

control comp or wear

have you tried it with D2 = 0 ?

have you tried posting this with computer comp ??

 

I always use wear comp. My comp is only .0005

1. try using no cutter comp. even if your comp is set to 0.000 just having the G41/G42 throws in a whole extra set of calculations and I've seen it cause issues.

 

2. try linearizing the arcs so the chain is a bunch of very small line moves with no arcs (break many pieces). or you can disable arc output in the control def just to test it.

 

3. try disabling the high speed lookahead (G05P0) for this path. Depending on settings having the G05P10000 can cause issues if your code contains lines and arcs. try running it with the high speed lookahead off with arcs and running with high speed lookahead off without arcs to determine if this is the issue.

Roger,

The problem with taking out the cutter comp is that I can not control the size. I will have to try linearizing the arcs when I get some time in the machine again. The one problem with linearizing the arcs here would be program size, We already have an issue with space in the control as is. I looked into it and I don't even have the option to use G5P10000.

 

To me it looks like G-code problem.

 

I would think that if it was a problem with the code it would have still showed up on our A61. I find it hard to believe that I just cant use arc's in my program for an A66.

might be arc tolerance parameters

 

did you look into this at all

Not yet, this will be the next thing I look into.

i'm not saying that eliminating the arc's are the solution, not using HPCC is the sollution, or not using cutter comp is the solution. Mostly just trying to find the root cause of the issue so it can be addressed properly.

I did some testing on this and if I used a M252 and it looks good. We are now looking into the parameters to see if we need to change something there.

Thanks for all the help.

[Tony35]

i use M251 and M252 on most of our programs

[BenK]

I just learned about these codes, I think I will be using them from now on.

look in the makino programming manual for all the different codes and what they do

 

M250

M251

M252

M253

M254

M255

 

i know there is more on the Pro5 control
