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 : Limit1 pin on X axis connector or W_RTD1 (sys30) 2 : Limit2 pin on X axis connector or W_RTD2 (sys30) 3 : Fault pin on X axis connector 4 : Home pin on X axis connector 5 : unused 6,7,8,9 : Limit1,Limit2,Fault,Home pin on Y axis connector 10 : unused 11,12,13,14 : Limit1,Limit2,Fault,Home pin on Z axis connector 15 : unused 16,17,18,19 : Limit1,Limit2,Fault,Home pin on A axis connector 20 : unused 21,22,23,24 : Limit1,Limit2,Fault,Home pin on B axis connector 25 : unused 26,27,28,29 : Limit1,Limit2,Fault,Home pin on C axis connector

 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)
