Hi,
Does anyone have an up to date set-up procedure for bed levelling on the current Marlin.
I have been going around in circles for days now (insane )....
I have followed Thomas Sanderer's video on YouTube, but when I get to the final calibration part I cannot for the life of me get the probe to go below the sensor trigger point.

Sorry if this a simple question....

Was using Repetier Host works in Ponterface...

You need to have your Z_PROBE_OFFSET_FROM_EXTRUDER set accurately. And... It may help to turn off the software endstops:


#define min_software_endstops true // If true, axis won't move to coordinates less than HOME_POS.
#define max_software_endstops true // If true, axis won't move to coordinates greater than the defined lengths below.


It sounds like you are using Grid leveling. In all of the Mesh leveling schemes (including UBL at [github.com]), going below 0.000mm is assumed to be necessary.

If you bring up the UBL system, I'll spend the time to help get over any problems you run into.

Since the probe is stopping early and wont move right down then
mostly likely you need to issue a G92 Z10. That tricks the controller into
thinking the z-min endstop is 10mm lower, or at least below the bed.

Must admit I used the Sanderer videos myself. Very nice productions.
