I'm trying to set up an autocalibration routine for my CNC that runs on startup and was thinking it would be possible to drive a tool into an axes probe in a known location and save that as a tool offset then drive it into a second probe of a known distance to probe X and calculate the sterps/mm from that. does anyone believe this to be possible

@markz thanks that solved it

Has anyone been able to get a traditional tool length setter (one that sits at a known X Y position and sits above the bed) to work with programs that require semi-auto tool changes eg that use multiple tools? I've been struggling to set it up in a way that is consistent between changes.

@chrishamm I've tried this before but could never quite wrap my head around it do you have an example of something that works with this?

@fcwilt because I run an open-source project for a 3d printed CNC and creep issues can be a problem causing different steps/mm a few weeks after first building. it also helps new builders at the end of the day set it up as it can be done with the click of a button rather than by themselves.

I'm trying to set up a Tool setter to probe z height between operations I'm trying to use M585 to do this but keep getting a constant "error no tool selected" ive defined the tool and spindle with M563 and have even got T0 at the end of the config file. i'm at my wits end with this firmware at the moment and could use the help.
