UMC750 using consecutive flow tool paths. C axis rotates excessivley between

Anonymous — Wed, 10 Jul 2019 19:13:19 GMT

Sorry if that description is miss leading.

I am practicing some simultaneous milling with our new UMC750. I have a few Flow tool paths in a row, and its creating this scenario where the table rewinds to 0 then rotates back to the last location it was in at the end of the previous Flow path. Why on earth is this happening. Why not just start somewhere within 359 degrees of 0 since its rewinding?

I assume there is something to be modded in the PP or perhaps the control. Any help will be great. The Code is attached.

What you are witnessing is a miscommunication between the post kernel and the post processor. The best way for you to resolve this issue is to inform the post kernel that the post processor will be resetting the C-axis to 0 at the end of a multi-axis operation, otherwise it always wants to start at the best angle closest to the previous multi-axis operation. You do this by adding the 'reset' parameter when creating the C-axis. This code is in the onOpen function.

var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], reset:1, cyclic:false, range:[-13320, 13320], preference:0});
