How to skip homing?
-
How do I skip the homing procedure? I would like to test some commands and setup before I hardwire my switches, but I keep getting errors.
Thanks!

either set your axes to a value with g92 or https://duet3d.dozuki.com/Wiki/Gcode#Section_M564_Limit_axes

Thanks! That worked!

How do I use an E axis without "selecting a tool"? I just want to use it to spin a spindle.
Thanks!

@tenaja create a tool, with just the driver, no heaters or fans. and then have T0 at the end of your config.g so its selected by default.

That let me select the tool, but then it is giving me a Temperature Reading Fault. (I have no heaters--how do I ensure that is not an issue?)
Thanks again!

@tenaja please post your config.g

@T3P3Tony, thanks, I posted it here:

You can set position as shown above.
-or-
Best practice for endstops is to wire each switch "Normally closed" and set the configuration M574 blah blah S1, where "S1" is "Active High". This allows the detection of a broken wire or connector (the endstop will appear triggered).
For setup, before you even have endstops wired, invert this. Set the M574 S0. This will cause the endstops to appear triggered all the time... this will cause a home (G28 or similar) to instantly complete with no errors. After the machine thinks it is homed, you can move, etc.
I use this trick a lot when setting up new machines.
Just don't forget to put M574 back to S1 when you do actually wire the switches. And always test them with your finger (observing the web interface, or M119) before you do the first home.
