Enable both PIN27 and zmin for bltouch and PIN29 for filament sensor #9

Closed pappicio closed 3 years ago

pappicio commented 3 years ago

Hi, I tryed to enable both pin27 and pin29, firts for bltouch with zmin stop, and also pin29 for filament sensor, result: filament sensor on pin29 doesn't work. I know, is not implemented into your releases, but adding fs on one of choice to compile, visual studio code add all needed, and also menu in the printer screen shows rounout (on/off), there is a possibility to add them both working? wait.... Maybe it appen only becouse I didn't use timer "M75" before start the printing (I use octoprint) not sdcard. I'll try to print using also M75 Gcode before print, maybe in this way all works as expected.... EDIT: nothing to do, also with Gcode M75, during print, the sensor on PIN 29 doesn't work,

In anycubic-kad-bugfix-2.0.x branch, anycubic_mega_zero_melzi_bl_zmin_fs or anycubic_mega_zero2_melzi_bl_zmin_fs should cover that config. btw, sensor by default is not activated, check in configuration menu to enable it, that also could be reason. (or see https://marlinfw.org/docs/gcode/M412.html to enable that over terminal).

Hi, thanks, I have mega zero 1.0 and also heated bed, so the first choice, is bad for me, but, can I use instead some mega zero 2.0 build, like "anycubic_mega_zero2_melzi_bl_zmin_fs", cos it has iet actived heat bed? thanks.

@pappicio I've uploaded to http://orava.kad.name/3d/experimental/

amz_melzi_bed_bl_zmin_fs-bugfix-2.0.x-20210403-firmware.hex amz_melzi_bed_bl_zmin_sfs-bugfix-2.0.x-20210403-firmware.hex

please try (sfs for BTTs smart filament sensor, fs for simple/cheap ones). If those are ok for you, I'll add those to regularly generated set.

waw, finally I can compile with all upgrades I have, without suppress sdcard support. For now just compiled, If I have some minutes free tomorrow I'll try to use filament sensor (I use simple, with only 2 wires: first connected on PIN29, second on GND). I'll tell you if all works with it, asap! thanks. P.S.: seems (or I'm wrong...) amz_melzi_bed_bl_zmin_fs-bugfix-2.0.x-20210403 not enables advance_pause_features and nozzle_park_feature, but only after try, I can see, btw, disabling sdcard support (I use octoprint!), and enabling all (fs, avanced pause and nozzle paek by hands), and sensing filament on octoprint (raspberry) gpio, sending M600 command to the printer, I'm able to pause print, park nozzle, change filament and continue print with new filament, but, I'd lime to have it directly on marlin, without the support of octoprint.

pappicio commented 3 years ago

ok.tested amz_melzi_bed_bl_zmin_fs-bugfix-2.0.x-20210403-firmware.hex.all works except runout filament (I connected simple filament sensor on EXT - A2, 2 wire: pin 29 and GND). gcode M119, about tell me info, triggered or open, but nothing appen inserting o removing filament from sensor. On lcd I only can see enable filament sensor; connecting sensor on melzi board, nothing appen during printing; other runout filament connected on raspberry (octoprint): it only stops printing cos send pause print to octoprint, but nozzle stay there on printing area. If I enable also: avanced pause and nozzle park, if open filament sensor on raspberry, it pause print, nozzle goes safe area of printing area and wait for filament change, and on lcd I can follow instructions about; at filament changed, I can confirm, nozzle pre heat and then print resume (only after I pressed also button "resume" on octoptint interface), so: If I disable SDCARD SUPPORT and force to compile also avanced pause and nozzle park, having more free flash ROM, and only with support of octoprint (send M600 command to the printer after it senses print pause by its own filament sensor), I'm able to change filament in safety mode and can then resume print. I only hope that will be possible without octoprint after I've received new MINI MZ board for my Mega Zero Printer. btw, thanks a lot for your support and all your work on marlin firmware for Mega Zero!

On Melzi board, there is no really space for M600, that's why it's disabled. On Melzi only possibility is to do M25 (sd print pause), thus functionality is limited to SD printing only. For M119: if you don't see changes in state if you're inserting or removing filament - recheck wiring. pull-up resistor on that input is enabled, so if it correctly shortened to ground, it should be in low state.

pappicio commented 3 years ago

yes, thanks for confirmation, I tested with a multimeter, on the filament sensor, the 2 wires (PIN29 and GND) goes to ground when connected, (I can see 5v, if I remember well) but nothing appen if I open contact by switch (so, PIN 29 goes to pullup), print doesn' t pause. I think maybe something is wrong... but here, someone else who tryes filament sensor, could confirm or not.

pappicio commented 3 years ago

okok, something seems to move now: ok, I use Octoprint to remotely print, not need use builtin SDCARD, so: in "Configuration.h" I modified: this

if ENABLED(KAD_MELZI)

#define FILAMENT_RUNOUT_SCRIPT "M25"

to

if ENABLED(KAD_MELZI)

#define FILAMENT_RUNOUT_SCRIPT "M600"

this // #if ENABLED(KAD_MELZI) && ANY(KAD_SMART_FILAMENT_SENSOR, KAD_FILAMENT_SENSOR) && DISABLED(KAD_BLTOUCH) // #define NOZZLE_PARK_FEATURE to

if ENABLED(KAD_MELZI) && ANY(KAD_SMART_FILAMENT_SENSOR, KAD_FILAMENT_SENSOR) ///// && DISABLED(KAD_BLTOUCH)

define NOZZLE_PARK_FEATURE

this

define SDSUPPORT

to

if ENABLED(KAD_MELZI) && !ANY(KAD_SMART_FILAMENT_SENSOR, KAD_FILAMENT_SENSOR, KAD_BLTOUCH)

define SDSUPPORT

(so I disabled DS CARD SUPPORT to have many more flash ROM feee)

in "Confoguration_adv.h: this // #if ENABLED(KAD_MELZI) && ANY(KAD_SMART_FILAMENT_SENSOR, KAD_FILAMENT_SENSOR) && DISABLED(KAD_BLTOUCH) // #define ADVANCED_PAUSE_FEATURE to

if ENABLED(KAD_MELZI) && ANY(KAD_SMART_FILAMENT_SENSOR, KAD_FILAMENT_SENSOR) ///// && DISABLED(KAD_BLTOUCH)

define ADVANCED_PAUSE_FEATURE

in my way I have: Heated bed (with added mosfet); bltouch (on PIN27 and Z stop); Filament Sensor (ON EXT-A2, PIN29-GND)

I enabled ADVANCED_PAUSE_FEATURE and NOZZLE_PARK_FEATURE, disabled SDSUPPORT, and enabled M600 Instead of M25. Now, during print, if I remove filament from 2 wire Filament Sensor (installed on PIN29/GND), after 5mm of filament (I setted limit to 5mm...), print pause, nozzle goes to secure position and lcd tell me to change filament, anfer after I've followed instruction appeared on lcd, I can resume print, and without do anyting on octoptint interface, I'm happy (sure, I've lost SD CARD, but really not need it, I watch tv from my livingroom and choice the object to print by octoprint interface!) Thanks for your time, and in future, if you want make this modification to add full support for filament sensor joined to bed and bltouch, surelly someone else will be appy about, but losing the use of SDCARD, only for people who use octoprint.... see you!

kad commented 3 years ago

ok. I'll keep that issue then in that state, if someone wants to repeat it. I think loosing SD support might be ok for some, but that probably needs to be conscious decision :) Generally, it is anyway better to upgrade from stock Melzi board to something else (at least, for the sake of better motor drivers). Thx for trials.

pappicio commented 3 years ago

yes I know, is better change board, in fact I'm waiting for SKR mini mz (specific board for mega zero 1.0), but while wait, I like to have all upgrades ready and working, and now I have all them. yes, only disabling sdcard. btw, thanks for all! maybe I'll return here for new questions when I'll have under hands new board! :)
