Axis windup

[PeterM]

Ok, here's a post question, when transforming - rotating a toolpath. typically drilling holes around a part I get axis windup, a0 becomes a360, a720 etc. This windup carries thru subsequent tools, although the positions are technically correct, this is confusing to the operators. Is there a way to force a reset for each toolchange.

 

Using 9.1 mr0105, X sp1 update3

Look for this switch in your post and set it to 1

=================================================

one_rev : 1 #Limit rotary indexing between 0 and 360? (0 = No, 1 = Yes)

==================================================

This is where I fixed it in our post

--------------------------------------------

ctol : 180 #Tolerance in deg. before rev flag changes

---------------------------------------------

Hope this helps.

ctol: 180 had limited sucess, worked on a horizontal post, but not the vartical v9, nada on X

So do you have the switch in your post? Did it work for you?

[PeterM]

Latest update, jmparis I do not have your switch in my posts so no can use, I had edited my hass post using ctol : 180 #Tolerance in deg. before rev flag changes. did not work, I then edited my mpmaster post and that worked!

The switch is taken right out of the MPMaster.

 

Why not update that HAAS post to the MPMaster? I think you'd find it a lot more nimble in getting things done.

I like most things about the mpmaster post, however there are a couple of annoying things that I haven't taken the time to sort out. One when posting miltiple toolpaths with the same tool, starting values are repeated over and over in the program, also quotes are too skimpy. so for quick and dirty, simple little programs I like the haas post, for now anyway.

Your X installation should have included a Generic Haas 4X Mill machine def, control def and post. If you open the post in an editor and set force_index to yes$, the resulting output will stay between 0-360 degrees for drilling and toolplan positioning work:

 

force_index : yes$ #Force rotary output to index mode when tool plane positioning with a full rotary

 

In addition, the post resets the windup by default as frc_cinit is set to yes$ by default:

 

frc_cinit : yes$ #Force C axis reset at toolchange

 

BTW, I added a seperate rigid tapping cycle to the post for MR1/SP2 as requested.
