Multipass

Eli · Sep 18th 2019

I'm new at abb programming and having some issues with saving the paths(seamnames) to reuse for multipass using ArcRepl I keep getting errors that path is not stored

Uploaded the Seam Tracking with Weldguide III & MultiPass RW6.07 Operating Manual to the ABB manual section. This should have the information you need. Start with page 49.

Make sure your seam names is unique to your seams.

Eli · Sep 19th 2019

this is part of my code and its not working as far as saving the seamnanmes and loading to reuse again

Eli · Sep 19th 2019

errors I get

path load error

fail to read in path

SAABoholic · Sep 19th 2019

Which command triggers the error, MpLoadPath or ArcRepL

JMF · Sep 20th 2019

Question. Is the seam names stored as arrays or is it a string instruction?

As far as I know it should be "your_seam_name" if it is not declared in your data and "Your_seam_name{array nr}" if it is stored as array. NOTE the Inverted commas.

JMF · Sep 20th 2019

Also is your parameter set to "True" in the Trackdata for Store Path?

This must be set active to store the path names.

Eli · Sep 23rd 2019

will double check everything today once we get the cell up and running came across some issues and maintenance is working on it

Eli · Sep 23rd 2019

the error comes on once it's going to the Arcrepl

Do the seamnames have to be inside quatetions (inverted commas?

Eli · Sep 24th 2019

got it to work

I didn't had a string file for the weld paths to be stored in

Thanks JMF

Eli · Sep 26th 2019

another question how can I clear the weld paths on the program after i modify points.

Robot keeps going to the previous recorded path

Thanks in advance

JMF · Sep 27th 2019

When you use Multipass, you use the first weld as your reference to your mulitpass offsets. If your weldpath/reference weld change, your offsets will change. If you change you multipass data, your weld will be still referenced to where your first weld was only your offsets will adjust. So in short. When you change your weld path/reference weld, you need to rerecord that seam for the offsets to be accurately referenced to the weld path.

JMF

How do I re-record the seam or clear the values I already have in the strings ?

I modified the starting point and end point(root pass), but when I block through the program the robot goes to it's old seam for 2nd and 3rd pass

JMF · Sep 27th 2019

I do not know of a shortcut other than switch of welding and rerun the root pass as it would have welded and then switch welding back on after the run for the 2nd and 3rd passes. But what I have noticed is that your tracking might differ a bit because multipass requires tracking to be 100% correct.

Lemster68 · Sep 27th 2019

Try to PPtoMain and then PP back into your weld routine.

Eli · Sep 27th 2019

I will do so.......

made a new routine and now I'm getting the same errors as before "path load error" I did exactly the same thing when I got it to work now I'm lost once more....

Eli · Sep 27th 2019

there a place where I can check to see if the paths (seamname)are being stored??

Lemster68 · Sep 30th 2019

IRC5? You can use RS if so and search system.

Eli · Oct 1st 2019

in the instructions for Mpsavepath is the createlogfile supposed to be blank?
