Title: G28.1 with very long axis
Post by: RedBlob on June 25, 2015, 12:13:05 PM

Hello,

I have a very long axis and I need to use a G28.1 command to find the zero ( a precision mechanical switch ) .

If I use a low speed return to zero the cycle is very long but the precision is very goog.

If I use an high speed return to zero I have a very low precision in zero procedure.

I need to find the zero with an high speed in the first step of cycle and after to find the zero with a low speed procedure.

Have you an idea to switch the speed on the fly with a G28.1 command ?

Thank you for Help.
