Gcodes Not For Everyone

Advanced diagnostics and reporting. Not really secret, but intended for internal use.

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

       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)



M619 Map Aux Port

M619 sets the behavior (function and output timing) of a user-controllable switch (including aux ports and arm lights).

Normally we expect users to keep the defaults - but some people will want to remap logical functions to other physical pins. Here are the details.

This can be used to remap outputs associated with inputs, or to control frequency/duty cycle of outputs - or both.

So I can associate the Laser X-hair button (logical function) with my X-arm "danger" LEDs (physical pins), or I can associate my M7 button on the CNC tab (logical function) with my Y-arm light (physical pins).

Usage

 M619 Ln In Sn Hn On Fn Pn

Parameters

Ln

Ln is the logical function (or button push) that we want to affect.

Sn

Sn dictates the power level, 0-100.

Hn

Hn specifies the polarity of the sensor: 0 or 1 (H0 = active low, H1 = active high). HSS default to H1, Drains default to H0.

On

On can limit each execution to a single iteration with an O1. Other values default to no limit.

Fn

Fn stipulates the frequency in Hz for the signal. If Fn and Pn are both specified, only Fn is used.

Pn

Pn stipulates the period in seconds for the signal. If Fn and Pn are both specified, only Fn is used.

Example

Hey Davo, I want my Ultimus head to work on Aux2 (M8 port) instead of the standard Aux1 (M7 port).

Well, the easy way is that you can update the mapping by going to Settings > Printer on the I/O tab and click Apply.

The gcode way is to bypass the GUI and enter this command:

 M619 F12 I2

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

  • M619 (remap function)
    • F12 (external head function)
    • I2 (to Aux2 port)



M670 Toggle Y-Arm Light Now

Turn on Y-arm light immediately. S 0 - 100 for duty.



M671 Toggle X-Arm Lights

Toggle X-arm Lights S 0 - 100 for duty.



M672 Toggle Y-Arm with Sensor

See main Gcode page.



M673 Toggle Y-Arm Light Next

Toggle Y-arm light after all previous commands are finished. S 0 - 100 for duty.



M772 Reset All Metrics

In addition to info on the Gcode 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)



M773 Generate Basic Report

M773 generates a basic report of printing statistics (including average speed, number of primes, etc.)

Note: this report will be more meaningful if you use M772 to reset these counters at the start of a job.

M795 Set Jog Amount

M795 generates a sensor status report:

Usage

 M795 Sn

Parameters

 S is the amount in MICRONS for the Jog Increment

Example 1

 M795 S50

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

  • M795 (set Jog increment)
    • S50 (to 50 microns)



M797 Report Sensors

M797 generates a sensor status report:

Usage

 M797 In

Parameters

 I can be 1 (logical states) or 2 (physical values)

Example 1

 M797 I1

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

  • M797 (generate sensor report)
    • I1 (show logical states)

Sample Output 1 (30M/ESR)

 >GB: Logical States  (M797 I1)
 >GB: AX ST DR  HM L1 L2 FT
 >GB: == == ==  == == == ==
 >GB: X  -  F   H  .  .  .   <= in this example, X is currently homed
 >GB: Y  -  F   -  .  .  .   <= in this example, Y is not currently homed
 >GB: Z  -  F   .  .  .  . 
 >GB: A  not installed
 >GB: B  not installed
 >GB: <end>

Column definitions: AX - Axis ST - Step DR - Direction HM - Home L1 - Limit 1 L2 - Limit 2 FT - Fault

Example 2

 M797 I2

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

  • M797 (generate sensor report)
    • I2 (show physical values)

Sample Output 2 (30M/ESR)
