I'm trying to get Marlin 1.1.0-RC8 working on my DeltaMaker delta printer to replace the much older Marlin firmware the printer came with. Have everything working except the z-probe. The way this probe works is to engage a solenoid (not a servo) and then detect when a microswitch closes. I'm trying to figure out how to activate that pin during Z-probing.
In Configuration.h my choices are:
// Allen Key Probes, Servo Probes, Z-Sled Probes, FIX_MOUNTED_PROBE, etc.
// You must activate one of these to use Auto Bed Leveling below.
The one that seems closest to what I want to do (change the state of an I/O pin during z-probing) is "Z-Sled Probe", but when I try that, SanityCheck says "You cannot use Z_PROBE_SLED with DELTA." So before I start defacing SanityCheck.h I thought I'd do my own sanity check and ask if that is the correct/best sensor type for what I want to do, which is:
- Begin z-probe
- Set a "probe enable" pin to engage solenoid
- Wait for Z_MIN_PROBE_PIN to change state
- Flip state of a "probe enable" pin
- Clear that "probe enable" pin to disengage solenoid
