Gcodes Not For Everyone
Advanced diagnostics and reporting, 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
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)
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.
Usage
M619 Ln In Sn Hn [ Pn | Fn ]
Parameters
Ln dictates the logical triggering function (ex: mist), with the following values:
0 : no function
1 : mist coolant
2 : flood coolant
3 : X-arm light (30M/ESR only)
4 : Y-arm light (gantry on 16A)
5 : light around "respond" button (16A)
6 : reserved
7 : chamber recirc fan
8 : CO2 laser crosshairs
9 : exhaust fan
10 : vacuum
11 : air compressor
12 : pneumatic head
13 : CO2 laser power supply
In dictates what physical connection or port will be affected
On ESR and 30M models:
1 : HSS1
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.
