Z homing speed is really slow
-
I have an printer that started life as an Ender 3. Now it is a custom printer running a Duet 2 WiFi, linear rails for X and Y, and a E3D Revo hot end with a Mandela Rose Bed and 110V heater. When I home it using G30 the speed on the X and Y axis are reasonable but the Z axis homes really slowly. I have tried modifying M201, M203 and M566 a number of ways but it does not change anything on the any of the homing axis. I suspect G30 is overriding all other speed settings. Is this true? if it is, are there attributes that can be add to G30 to get it to run faster? I included config.g if that helps.

Did you try changing the values of the F or T parameters in your M558 command?
They control the probing speed (F) and travel speed (T).

@KenW
Thanks for both suggestions . Here are the speed control commands from my config.g. Trying the suggestions you both made I did not see and significant speed change by changing M558 F value. Do you see anything in the speed values that might be overriding anything else to slow down the Z axis.
Thanks

A max speed for Z of 180 is going to appear slow. The max Z speed on all my printers is 1200.

Acceleration Z20 will also make it seem very slow. Try 120 there.
