Problem on a Union Gera CNC

Hola txote

Tenemos un problema muy similar en un CNC Union Gera. Hemos configurado una nueva regla y al mover el eje Z salta mucho, sin regla el eje se mueve perfectamente, ya hemos probado esta regla en el eje Y y funciona sin problema. nuestro problema suena muy similar a su problema por lo que apreciaremos si comparte la respuesta tan pronto como lo resuelva o si lo resolvemos primero, le enviaremos la respuesta. tenga en cuenta que los datos de la máquina son correctos porque en X, Y ya trabajamos con reglas idénticas y trabajan muy bien.

Hello txote

We have a very similar problem on a Union Gera CNC. We have configured a new rule and when moving the Z axis it jumps a lot, without a rule the axis moves perfectly, we have already tried this rule on the Y axis and it works without problem. Our problem sounds very similar to your problem so we will appreciate if you share the answer as soon as you solve it or if we solve it first, we will send you the answer. Note that the machine data is correct because in X, Y we already work with identical rules and they work very well.

Hello,

You have installed this external scale on Z axis, so please check Z axis external scale related machine data values & check scale interfacing cable connections. 

Hi, dear experts

As additional data we have made progress tests and we have a backlash = 0 our ballscrew it´s new.

Hello,

The settings which you have reduced has caused drive sluggish. Durig interpolation operation with other axes, these setting values affects the perfomance. You can conduct ball bar test & check/compare  the performance.

You need to find out root cause of axis vibration, e.g. please check scale output, axis transmission clearances/bearings, motor/ motor encoder etc.etc.
