Warm-up program

[chuy]

There was a pretty cool warm-up program out there using macros...would do a figure eight shape moving the z up and down all syncrnized, also would elevate the speeds every few minutes. I thought I had it but I can't find it anymore.

Here is my example of a warm up progarm, however it dose not use macro's.

I home the machine out using G28, the use incrental moves to move the axis. If you us a feedrate of 60 IPM then it well take you 1 min to move 60 inches. The machine I wrote this for is a 30x20x24 and machine home is the top right corner to table.
