Initial Calibration
Mi problem is I can't get past first xyz calibration (4 points) it usually quits at third point.
Mi printer is a mk2.5 upgrading to a mk2.5s with mmu2s
To troubleshoot I went to autohome and it placed my pinda probe off by +3 to 5 mm in the x axis.
I was thinking of reprinting (after taking better measurments) the endstop block for the x axis but I decided to ask for help first.
I there might be a huge glaring detail I am missing and me and my hubris can learn something about this.
Some extra stuff.
I updated the firmware for mk2.5s to 3.7.0 and acordingly to the MMU2s unit.
I have built other of your machines I recived mk2s as a kit and I upgraded it to a mk2.5 with self solvable problems.
I'm attaching some pictures of the probe where it stops on autohome.
I can't calm down and take some Haribo cos I dont get haribo since im from Mexico. (I am calm tho)
I'm sorry for my grammar my english teacher kept telling me I should work on it but I haven't practice english correctly since 2005.

Hola, como esta. Yo tengo catarro, un donde esta los banos? Your English is much better than my Espanol.
I do not have experience with the Mk2.5 - but the initial cal of the four points is similar to the Mk3 procedure. Failures at that step are usually caused by the PINDA probe being too high off the bed. Lower the PINDA 0.5 millimeter and see if that helps.
Re: Initial Calibration
No experience with the 2.5(s) here, I have a Mk3(s). But such a difference between the old and the current firmware for the calibration is also there in the Mk3 - it is mentioned somewhere in the release notes, too. The reason is that Prusa wanted to get the PINDA probe better centered over the bed.
But quitting after the third point is unusual. Do you get any kind of error message on the display?
Re: Initial Calibration
First thanks both Markus and Tim for your time and expertice.
I ran a few tests, some promising, nevertheless futile in the end.
First as per Markus request I ran the machine the way I had it. The error message in display was "xyz calibration failed. Bed calibration point was not found."
Then as per Tims sugestion I lowered the PINDA probe a little, ran the test, got the same message but it quit at the fourth point (same message)
I lowered the pinda probe to slightly below the nozzle (I could say I went overboard), ran the test and it worked it told me the xyz worked and axis were perpendicular.
So with renewed happiness I tried to place it just barely before the nozzle (I used a spacing print marked 0.5mm. Ran the test... and it quit at 4th point (same message)
At this moment I decided to hope for the easter bunny to bring me some chocolate.
(didn't happen who knew when you grow old you are supose to buy the candy yourself).
Im open for new ideas, but I will keep trying hopefully with my spark gap spacers I can get the sweet spot.

First I like to mention that I'm also not good at forums :D.
