Yesterday we had a problem about our 840d machine. We were working with this post file. Then machine error occurred. I send eror picture and post file. May someone write their ideas ? The problem was in post or machine? Have you ever see this erors? I think its about machine. Because in post file, there is no Z-14.502 code but machine tried to go this positon. The operation Z level for finish with stagger ramp on part. Thanks for your answers.
