Hi
im using arduino due with ramps fd 1.2. when i type gcode g28 is giving me a error of "home Z first". i enable Z_SAFE_HOME and i get that error. when Z_SAFE_HOME is disable the z axis is not centering and the servo endstop is not able touching the bed because my Y0 X0 is off the bed. can someone help me

Hi,
It's possible to make preview of print with more zoom?

I get this when i try to compile with thermal_protection (hotend and bed)

Ciao Mago
I have this error building the latest version of MKDUO.
What can be?
thanks

With new version, autolevel doesn't works

Mine burned DUE (dead mega16u2 + Rx uart_0) doesn't restart on connect"(may be just mine board, Ï'm not sure) then work not via UART_0.
I propose to add folowing:
//Defines so the device can do a self reset
//https://forum.arduino.cc/index.php?topic=345209.0
#define SYSRESETREQ (1<<2)
#define VECTKEY (0x05fa0000UL)
#define VECTKEY_MASK (0x0000ffffUL)
#define AIRCR ((uint32_t)0xe000ed0cUL) // fixed arch-defined address
#define REQUEST_EXTERNAL_RESET (AIRCR=(AIRCR&VECTKEY_MASK)|VECTKEY|SYSRESETREQ)

REQUEST_EXTERNAL_RESET can be for example call from MK_Main.cpp after FlushSerialRequestResend() in inline void gcode_M999().

I'm no sure that someone except me need this, but this feture gives apportunity to reset device by button (in pronterface, by M999 command). Never understand why stock button "Reset" in pronterface interface doesn't reset the board. Or does ?

According to http://reprap.org/wiki/G-code#M851:_Set_Z-Probe_Offset , MK4Duo supports M851, but that is not correct. M666 is used instead, which is actually used for delta endstop adjustment. The P parameter is not standard either.
Even though things work just fine the way they are, I suggest to use M851 for probe offset

I get errors when compiling . SMART Ramps still not supported....

WIth this new version of firmware when I open a gcode file in pronterface or repetier host printer doesn't heat extruders and doesn't start to print.
When sometimes works, when extruder temp is ok doesn't start to print.
The same gcode with another version of MK4Duo works without problems.
It's seems that data comunication between printer and computer not works well.
Printer returns Txxx / Txxx when before returns W: too, and other values.
Other version returns
ok T:18.8 /0.0 T0:18.8 /0.0 T1:18.8 /0.0 @:0 @0:0 @1:0

Error compilación en tarjeta Arduino/Genuino Mega or Mega 2560.

Compiled with Arduino IDE 1.6.8

Well, without errors compiling the code I've a new issue.
Both extruders moves together with tool 0 selected or tool 1 selected.
I Think that if I've a dual X carriage I've a independent extruder movement, but doesn't it.

I've tried all carriage modes but doesn't works.
With Marlin firmware, when I made X homming or movement, each extruder works independent.

change KILL_PIN not work while PID (M303) calibration in progress.
is dangerous.

Error compiling for board Arduino/Genuino Mega or Mega 2560.

In Configuration_Feature Nextion port it's defined:
#define NEXTION_PORT 1

This is incorrect.
Correct was:
#define NEXTION_SERIAL 1

Temperature readings on my RADDS Dual extruder setup work fine with both extruder temp sensors. Today, I uploaded the same codebase / different config to my Megatronics V2 board, also dual extruder setup, but I did not get any reading of the 2nd temp sensor. All wiring must be correct since original Marlin firmware works. Pins are correct (compared with Marlin).
Temperature of 2nd extruder DOES get reported in Pronterface if I switch to T1 but only one at the time. On RADDS, I can see T0 and T1 at the same time. Repetier-Server does not report T1 at all....

Hi,
Since I am a git beginner, I will inform you on issue.

Thank you.

If I made a auto bed leveling with G29 command, after leveling if I move Z axis to 0 , Z axis doesn't stop

If I made a singel auto bed leveling with G30 command, after leveling if I move Z axis to 0 , moves correct and stop bed ... EDIT, not always occurs.

I've homming endstop at ZMAX pin and ZPROBE on pin 32.

8156fcf

this commit breaks almost everything ;) The Printer is homing but dont give the right positions. if i use a Y Max Endstop it tells y=0. so the printer will not move in Y.

The missing EEPROM is a showstopper for me. I saw that you support it on Ramps-FD V2 (only exist as blueprint / DIY board as far as I know). Would it be feasible to add support for a cheap EEPROM Data Module - as described here http://www.instructables.com/id/Adding-an-24LC256-EEPROM-to-the-Arduino-Due/

If I knew how to code this myself, let alone have some hardware knowledge, I would do it myself. Instead I did some research to get you kickstarted:

http://www.hobbytronics.co.uk/arduino-external-eeprom
http://www.hobbytronics.co.uk/eeprom-page-write
http://www.jechavarria.com/2013/06/28/components-i-usually-use-ii-24lc256-i2c-eeprom-memory/
Lastly, a library that works for 24LC256:
https://github.com/JChristensen/extEEPROM

If you need any assistance in testing, I would be glad to help.

  G28 Z0 ;move Z to min endstops
  G29 ;auto level
  Resulting in console out:
  12:20:53.365: G29 Auto Bed Leveling
  12:20:53.369: ABL: Off (2)
  12:20:53.369: Reset Bed Level

• Issue 1:
  Why does it say ABL: Off? I have these settings:
  #define AUTO_BED_LEVELING_FEATURE
  #define AUTO_BED_LEVELING_BILINEAR

• • If I enable ABL with M320, I get
    12:33:55.471: ABL: On
    12:33:55.477: ABL Fade Height = 0.00
    Then another G28, I get
    12:34:30.060: ABL: Off

• Should a M320 be included in the Gcode before every print? Am I missing something?

• Issue 2:
  G29 returns NAN for Z:
  12:22:23.040: X:196.000000 Y:280.000000 Z:NAN E:0.000000 Count X:39200 Y:56000 Z:26235
  As a result, prints start somewhere above the bed.

Hello, there is probably a problem with the laser.
I use Arduino Mega 2560 with Ramps 1.4. I use the 1 pin (D5) configuration.
All other settings are unchanged. Although the laser is deactivated, it always returns after a few seconds.
Raster engraving also seems to have a bug. When engraving I get only lines. I use the Inkscape plugin. With another Marlinfirmware it goes without problems.
Sorry for the computer translation.

Hi Mago
I have a compile error in line.

C:\Users\io\Desktop\MK4duo\src\nextion\Nextion_lcd.cpp (1 hit)
Line 508: if (ptr == &Hotend3) {

C:\Users\io\AppData\Local\Temp\build8e7764853ccdabc298b7c2bc4c65a0b0.tmp\sketch\src\nextion\Nextion_lcd.cpp:508:19: error: 'Hotend3' was not declared in this scope

   if (ptr == &Hotend3) {

Another question. Why with the 4.3.X version I'm not able to communicate with pronterface?
When I click on connect button I see the log of the connection but I do not see temperatures and it is unresponsive at the gcode command.

Thanks

During a print job, motors will stop but heats will stay on.

Using Repetier Host over usb, G-Code still sending as though everything is fine because Arduino Mega is sending 'ok'

When compile last version of firmware raise this error:

/tmp/arduino_build_746019/sketch/src/eeprom/eeprom.cpp: In static member function 'static void EEPROM::ResetDefault()':

Hi,
is it possible to use a 1.3" oled screen with the radds over i2c?
I have no space for a classic display and need a small one to control my printer.

Hi,
An error occurred in ultralcd.cpp.
Please correct the following.

Thank you.

problem:
u8g lib not supported hardware SPI in st7920 on Arduino Due
olikraus/U8glib_Arduino#13

hardware:
ReprapWorld Graphical LCD screen v1.0 + Ultratronics Pro v1.0 (Arduino Due based)
Current release firmware work (in software SPI mode), but reaction on encoder clicks very slow: 1-2 sec when print in progress and SDCARD reading.

Any way to porting MK4Due from u8glib to u8g2lib ?

P.S.
I tried to do it yourself, but my knowledge is not enough :(
I know many people who have just such hardware

P.P.S.
sorry for the machine translation

Hi!

I would like to set my 3 extra extruders ofmy ultratronics to be Z axis so I can have 4 motors dealing with the massive weight of a bed I am building. How can I do it?
Would be awesome if you had in configurations.h a stepper to axis set up. It would open the doors to more exotic setups!

Hi,

i will build a printer with an auto tool changer like this:
https://www.youtube.com/watch?v=unsQ9i-nBNc
What is the best way do get the gcode in MK4duo to put a tool by side and get the other tool. I found in the nozzle a feature "park" but if i understand it right it is not what i need.

desc:
first print head get a tool (level switch) for auto bed leveling
then change this tool to print with e0
then park e0 (e0 and e1 on the left head side) and move to e1 to print....

BR Hexxter

you make a nice work!

I get this

Ciao Mago,
ho un errore di compilazione per l'MK4Duo 4.3.09_dev su una i3 con display RepRapDiscount Smart Controller.
Ho provato a usare due versioni dell'Arduino IDE, 1.6.9 e 1.6.13, ma il risultato è lo stesso.
Ecco l'errore:

sketch\src\lcd\ultralcd.cpp: In function 'void _lcd_level_bed_get_z()':

sketch\src\lcd\ultralcd.cpp:1213:12: error: crosses initialization of 'bool debounce_click'

   bool debounce_click = false;

Errore durante la compilazione per la scheda Arduino/Genuino Mega or Mega 2560.

Grazie per tutto il lavoro che fai.

With last version of firmware the direction of the second extruder motor isn't correct.
It's moves at the same direction that first extruder causing collision with the endstop.

For your info , in the previous version if the X or Y offset of second extruder was great than 0 or positive movement of second extruder was wrong too.

Otherwhise, Z offset of first extruder always is to be 0.0 , in previous version not:

in my case: #define HOTEND_OFFSET_Z {-0.2,-0.1, 0.0, 0.0}

I am not sure if my findings are specific to my setup. I use repetier server on a raspberry pi to connect to RADDS via native port (i.e. fast baud rate 460300, hardly any corrupted or lost data). I read elsewhere (https://forum.e3d-online.com/index.php?threads/new-linear-advance-extrusion-algorithm-significant-print-quality-increases.1893/#post-22135) that LIN_Advance might be restricted to printing from SDCard due to the read speed (!?)
From http://marlinfw.org/docs/features/lin_advance.html I read

Keep in mind that enabling this feature will add extra load to the processor and also your extruder hardware. I recommend to stay at 115200 baud communication speed, specially if you get error messages in your print host software or you get wired movements of your print head. Ensure your print host software is using line numbers and checksums, this is disabled by default in Simplify3D.

Now, when I activated LIN_Advance and set K to 75, my printer started to stutter. Interestingly, the amount of time the printhead paused moving was almost always the same:

To me, that does not look like a communication / bandwidth issue, but more as if the delay stems from the code itself. I will run another test with slower baud rate and see if the delay stays the same....

Maybe this is completely unrelated, but I noticed that in HAL.h, it says
define REFERENCE_F_CPU 16000000 // 16MHz MEGA2560[]
but I could not find REFERENCE_F_CPU for Arduino Due (84 MHz) or other boards.

Hello!
Thanks for you work.

I have H-bot/CoreXY on Arduino DUE + RADDS + RADDS LCD, with Z dual STEPPER Drivers and Z dual EndStop at MAX positions.

If I don't put the parameter Z dual EndStop, everything works fine, but of course, does not work Z2_ENDSTOP.
If I put the parameter Z dual EndStop, I can't choose on which PIN to connect it.

Which PIN is assigned Z2 MAX ENDSTOP by default?
I have it connected as X_MAX_PIN. How do I configure the firmware that it would work correctly?

Thank you.

M303 GCode for PID autotunning always works over the first extruder (E0)
