G38 Distance Probing

G38 will move the bed until a probe until contact is made, and report the position when contact is made, storing a list of coordinate points with depths. This is helpful for making the bed level (and potentially working on non-planar surfaces).

Usage

 G38 Xn Yn Zn An Bn T# Pn Dn In Hn On Fn

Parameters

 Xn relative move in this axis
 Yn relative move in this axis
 Zn relative move in this axis
 An relative move in this axis
 Bn relative move in this axis
 T# head where probe is loaded; if no T#, probe is not in a tool position; default: no T
 Pn probe connection
     If T is specified, P values can be:
       0  : PA3 pin on 10-pin connector
       1  : PA2 pin on 10-pin connector
       2  : LIMIT1 pin on 18-pin connector
       3  : LIMIT2 pin on 18-pin connector
       4  : RTD1 pin on 18-pin connector
       5  : RTD2 pin on 18-pin connector
     If T is not specified, P values can be:
       0  : No direct connect probe; canbus based probe one  *** must specify probeHead via T arg
       1  : X Limit1 or W_RTD1 (sys30)
       2  : X Limit2 or W_RTD2 (sys30)
       3  : X Fault
       4  : X Home
       5  : unused
       6  : Y Limit1
       7  : Y Limit2
       8  : Y Fault
       9  : Y Home
       10 : unused
       11 : Z Limit1
       12 : Z Limit2
       13 : Z Fault
       14 : Z Home
       15 : unused
       16 : A Limit1
       17 : A Limit2
       18 : A Fault
       19 : A Home
       20 : unused
       21 : B Limit1
       22 : B Limit2
       23 : B Fault
       24 : B Home
       25 : unused
       26 : C Limit1
       27 : C Limit2
       28 : C Fault
       29 : C Home
 D only 1 is presently supported; other options for future development
 I is probe polarity; 0 if contact makes a circuit, 1 if contact breaks the circuit
 H head offset register to use for tool dimension
 O additional offset
 F feedrate in mm/min (nonpersistent)

Example

 G38 Z-9 T# P3 D1 I1 F200 

This command is decoded and executed by the printer as follows:

• G38 (probe)
  • Z-9 (9 mm in Z toward 0)
  • T# (target head)
  • P3 (LIMIT2 pin on 18-pin connector)
  • D1 (only option)
  • I1 (contact breaks circuit)
  • F200 (at 200 mm/smin)

M772 Reset All Metrics

In addition to info on the Code page, these other reports are available:

 M772 - reset all internal data gathering to “0” state
 Sn - optional.  If Sn != 0, then Sn is a mask of which reports to auto send when M30 is processed.   S1 or S3 are typical user settings to get basic print info.
 Bit0 (0x01): enables M773 report (basic print stats)
 Bit1 (0x02): enables M774 report (system configuration)
 Bit2 (0x04): enables M774 report (queue metrics)
 Bit3 (0x08): enables M775 report (crashDataFromRam)
 Bit4 (0x10): enables M776 report (command and motionQ usage)
 Bit5 (0x20): enables M779 report (slice timing)
