1.1.x_bugfix Leveling issues

Hi-

I am having trouble with bilinear bed leveling with the 1.1.x bugfix release. I can not determine if its the sensor being flakey or if its the firmware.

Here is a video of Autohoming and G29 leveling. The bed does not properly retract/advance when its probing points 6, 7 & 8.
[photos.app.goo.gl]

Here is a copy of my logfile with debug turned on. At around line 2590 is where i am determining the probe trigger value. The Bilinear grid is reported at line 3130.
[drive.google.com]

2018-06-01 00:13:14,228 - Recv: Bilinear Leveling Grid:
2018-06-01 00:13:14,229 - Recv: 0 1 2
2018-06-01 00:13:14,231 - Recv: 0 +3.911 +3.733 +3.591
2018-06-01 00:13:14,233 - Recv: 1 +3.939 +3.877 +3.873
2018-06-01 00:13:14,234 - Recv: 2 +8.945 +8.948 +4.000
2018-06-01 00:13:14,236 - Recv:
2018-06-01 00:13:14,237 - Recv: G29 uncorrected Z:9.00
2018-06-01 00:13:14,238 - Recv: corrected Z:4.04

I leveled the bed corners as best I could before I autoleveled, so I really don't believe the mapping or corrected Z of 4.04mm.

Is the probe being flaky or is it Marlin?

Thanks

What are your steps/mm for the extruder in the configuration file?

Are you taking into consideration the changes in native usteps?

Double checked your electrical connections? What about wiring? Are you pairs rights? If it wall all working fine then it wouldn't apply but if you have a break in a wire somewhere, it could mimic bad wiring.

You mesh points are very large. This implies you do not have your Z_PROBE_OFFSET_FROM_EXTRUDER set correctly.

You mesh point values should be centered around 0.00 mm.

thanks for the reply. maybe i was not specific enough- yes, i understand that i should be somewhere around 0 for the mesh points. this is how things were looking when i first got the probe.

my Z probe trigger heights have been slowly but steadily creeping up. when i got the probe, it was triggering around 2.6mm. when things started going weird, i backed-up and calibrated. then i got like 2.8mm. things worked for a while, then got weird again. i recalibrated then i got a value of 3.2mm. then again after a few days, until i have gotten up to 3.8mm.

did you watch the video? what would cause the probing to go the other way? points 6, 7, & 8 dont retract/return like they should.

i am trying to figure out if this is a probe issue or marlin issue.

Connecting 2 E mottors

Hello! I have CTC dual with MIghtyboard electronics and changed firmware to Marlin (attached to post). I would like to control both E motors simultaneously, as one motor. I tried to use mixing extruder module but it didn't work because of thermocouples as termistors and thermal protection of marlin. Do you have an idea where I need to add a code line to connect both stepper motors? :)

Ps. I can't attached Marlin file so here is a link to soft [reprapy.pl]

Invert Logic of any Digital Pin used for Fans and Lights

Hi Folks,
I did some smaller mistake in my Hardware "design" as I soldered a small Board to switch Fans and Lights With D47 D45 D43 and D41
The Board Works as expected but Digital HIGH turns the light off and so on. in Most Cases this is not a Problem as i turn them on by Terminal anyway.
Just with the CONTROLLER_FAN. I thought is must be easy to invert this in Firmware but did not find any till now... could someone Help me here or lean me in the right direction?

Clear simple Question: I Want D45 "CONTROLLER_FAN" to be Off if the Steppers need cooling...

Thanks in advance..

Ah and this is Marlin 1.1-daily complety rearanged Pins on kinda like RAMPS 1.4

And Where is your part cooling Fan connected to? it looks like you have your Partcooling fan also on Pin 8.
this is not allowed, and would make no sense, because Partcooling would be always on With the Hotend..

There have been some changes to the probing code over the last 2 weeks in response to issues of probing on the edge of the bed.

It is very possible the lastest code addresses some of what you are seeing. Can you try the current code?

This WAS with the current code, bugfix from 5/26/2018.

What should I be using instead?

Hi kabelfrikkler,

I have attached a photo from rambo board.
I have my extruder's heater block connected to "heat 0".
The extruder's fan is connected to "fan 0" and this is pin 8.
The part cooling fans are connected to "fan 2" and this is pin 2, as per pins RAMBO in marlin

The problem is that when I try to upload:
#define E0_AUTO_FAN_PIN 8, it gives me the following:
SanityCheck.h:977: error: #error "You cannot set E0_AUTO_FAN_PIN equal to FAN_PIN."
#error "You cannot set E0_AUTO_FAN_PIN equal to FAN_PIN."
So it must be a bug somewhere.

For the part cooling fan, I have tried:
#define FANMUX0_PIN 2, but when I give the M106 the extruder's fan is starting. this is wrong.

That code is a week old. And changes have been made to it.

If the changes don't fix your issue, please start a thread at [github.com] and we will get the right people focused on it.

There are many articles of how to change the Marlin start up Screen or Custom Boot Screen for Marlin. try the two links below.

[community.robo3d.com]

[www.youtube.com]

Still need help post again

Thank you for your help but unfourtunetly every post about how to change boot screen is for full display graphic lcd but what i want to change is normal 6*12 lcd which is called i believe reprap discount lcd.

Do you know how can i do that on 6*12 lcd?

This RepRapDiscount Smart Controller contains a SD-Card reader, a rotary encoder and a 20 Character x 4 Line LCD display.

Boot Screen Message in RED

To remove it use "//"
//#define SHOW_BOOTSCREEN

To change it

ultralcd_impl_HD44780.h

#if ENABLED(SHOW_BOOTSCREEN)
******************************************************
}

static void logo_lines(const char* const extra) {
int16_t indent = (LCD_WIDTH - 8 - lcd_strlen_P(extra)) / 2;
lcd.setCursor(indent, 0); lcd.print('\x00'); lcd_printPGM(PSTR( "------" )); lcd.write('\x01');
lcd.setCursor(indent, 1); lcd_printPGM(PSTR("|Marlin|")); lcd_printPGM(extra);
lcd.setCursor(indent, 2); lcd.write('\x02'); lcd_printPGM(PSTR( "------" )); lcd.write('\x03');
}

This is not a logo it is plain Text. In green Number 8 is how many characters in printed string. This centers text on LCD.

Can be replaced with Marlin Font - Text up to 20 characters X 4 lines.
If these lines are not used

//#define STRING_SPLASH_LINE1 SHORT_BUILD_VERSION "" // will be shown during bootup in line 1
//#define STRING_SPLASH_LINE2 WEBSITE_URL "" // will be shown during bootup in line 2

This appears to be the character Set Used. DISPLAY_CHARSET_ISO10646_1 Could be wrong!!

The 20x4 LCD Displays allow 'custom characters' to be defined. The corners of the box are customer characters. Marlin also uses custom characters with the UBL Mesh Edit from the LCD Panel. It uses them to construct a grid of the mesh points and to show you which mesh point you are editing. lcd.write('\x00'); through lcd.write('\x03'); are the custom characters needed to make the corners of the box.

Just removing the lines within the logo_lines() function will get rid of the Marlin logo. But why would you want to hide the fact you are running Marlin firmware?

TEMP SENSOR CHAMBER

While running through a configuration.h file the other day on this 3D forum, spotted the following line of code.

#define TEMP_SENSOR_CHAMBER 0

It however it had no other supporting information with it. I have searched the Web for any information of where to find a version of Marlin that supports this for Ramps 1.4 if available.

Any Help would be Welcomed!

OK, found that Marlin 2.0.X has "#define TEMP_SENSOR_CHAMBER 0" included However do not know much about this Version "

Can this be upload this onto a Ramps 1.3/1.4 compatible controller, that was previously running Marlin 1.1.5.
