[BUG] Need support for configure the Mag mounted probe for working properly

[AnandRaj-R]

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

Yes, and the problem still exists.

Bug Description

First thanks to all for giving the best firmware also you are the best support team and i need your support,
i am facing some trouble while configuring the mag mounted probe,
First problem is no more detailed description about the probe configuration block and also the probe location coordinates are relative or absolute?
The second problem is while homing, toolhead going to the middle of the bed without attaching the probe and crashed on the bed. Even though configured correctly i think.

Bug Timeline

None

Expected behavior

When homing, Toolhead should go to the probe location and attach probe and then go to the middle of the bed or defined homing location and complete the homing procedure then return back to probe location and release the probe.

Actual behavior

While homing, toolhead going to the middle of the bed then return to probe location and attach the probe and again going back to the middle of the bed then complete the homing then return back to probe location and release the probe with PROBE ERROR, some time toolhead going middle of the bed without attaching the probe and crashed.

I don't know much about this, but here some general tips.

1. After making configuration changes execute a M502 (factory reset), write down you Z-offset values before you do this (M851). Then set your z-offset back and execute a M500 to store the settings, and reset the printer.
   Now try again.

2. Put something on you bed while testing to protect your bed and nozzle.

3. Use a M401 to see if it picks up the probe, and a M402 to put it back.

Hi, thank you for your tips, i tried all the above but same result. Also, i have a question why the toolhead going middle of the bed without attaching the probe also why marlin do not raise any error?

How do you know it doesn't?

Because of the printer homing behaviour and the toolhead going to perform the homing procedure with out probe even if the probe enabled and probe locations also defined .
