[BUG] Deploy/Stow wrong behaviour with a magnetic mounted probe

[Arloag]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

First of all, thank you very much to all the developers for the great work!!!!

And now the problem:
I´ve added a magnetic mounted probe on my self-made delta 3D printer, but the behaviour of the deploy and stow movements are not working correctly (in my humble opinion).

After homing, the deploy funtion makes no movement (neither with M401 in repetier nor with the option in the printer menu).
The stow function makes the correct movements, but after them a Z probe error appears (err: ZPROBE)

Bug Timeline

I also had the same problem with the previous version of 2.1.2.2 (maybe the 2.1.1.?)

Expected behavior

• The deploy function should move the effector to Z100, then move it 2cm to the left (X-20) and then return to the center (X0).
• The stow function should do the same but in the oposite side: move the effector to Z100, then move it 2cm to the right (X20) and then return to the center (X0).

These movements are just for testing pouposes.

The configuration is:

#define MAG_MOUNTED_PROBE
#if ENABLED(MAG_MOUNTED_PROBE)
#define PROBE_DEPLOY_FEEDRATE (5060) // (mm/min) Probe deploy speed
#define PROBE_STOW_FEEDRATE (5060) // (mm/min) Probe stow speed

#define MAG_MOUNTED_DEPLOY_1 { PROBE_DEPLOY_FEEDRATE, { 0, 0, 100 } } // Move to side Dock & Attach probe
#define MAG_MOUNTED_DEPLOY_2 { PROBE_DEPLOY_FEEDRATE, { -20, 0, 100 } } // Move probe off dock
#define MAG_MOUNTED_DEPLOY_3 { PROBE_DEPLOY_FEEDRATE, { 0, 0, 100 } } // Extra move if needed
//#define MAG_MOUNTED_DEPLOY_4 { PROBE_DEPLOY_FEEDRATE, { 0, 0, 100 } } // Extra move if needed
//#define MAG_MOUNTED_DEPLOY_5 { PROBE_DEPLOY_FEEDRATE, { 0, 0, 100 } } // Extra move if needed

#define MAG_MOUNTED_STOW_1 { PROBE_STOW_FEEDRATE, { 0, 0, 100 } } // Move to dock
#define MAG_MOUNTED_STOW_2 { PROBE_STOW_FEEDRATE, { 20, 0, 100 } } // Place probe beside remover
#define MAG_MOUNTED_STOW_3 { PROBE_STOW_FEEDRATE, { 0, 0, 100 } } // Side move to remove probe
//#define MAG_MOUNTED_STOW_4 { PROBE_STOW_FEEDRATE, { 0, 0, 100 } } // Side move to remove probe
//#define MAG_MOUNTED_STOW_5 { PROBE_STOW_FEEDRATE, { 0, 0, 100 } } // Extra move if needed

Actual behavior

• The deploy function does any movement
• The stow function does the correct movements, but then a Z probe error appears.

In my opinion, since the deploy and stow functions should just pick up the probe from its support and return it back, the probe itself should perfom any action, therefore I don´t understand why the Z probe error appears (err: ZPROBE).

Steps to Reproduce

1. Connect the printer
2. Home the printer
3. Check the deploy and stow functions through the printer´s menu or through repetier (with M401 and M402)
