Problem with toolchange in Mazak Quickturn nexus II

[Legenden]

Hi! I´ve encounterd a problem with the toolchange when using tools with Y-axis offset. For example, we welded two toolholder together, one left and one right, then change the offset in the Y-axis to +25/-25mm and it works great... until the toolchange, the machine goes to overtravel due to the limit in the y-axis when the machine go to the zero return point. Is there a way to work around this???

cancel your offset first and move back to y0 before going to the tool change position.

thats exactly it, uperez!

Turret will not index if Y axis is not home. this requires a manual unit in program with the same tool that brings Y to home before calling the next tool.

matrix has a y axis out of position tolerance parameter for this, but it's not good to exceed maybe .005" or so if you do manage to find it!
