Hi, i am on Step: Stage 09:Firmware - Step 12 Connect to Pronterface after Connect to the Printer:

1.

Connecting...

start

Printer is now online.

echo:Marlin 2.0.5.3

echo: Last Updated: 2020-03-31 | Author: (none, default config)

echo:Compiled: Aug 14 2020

echo: Free Memory: 3407 PlannerBufferBytes: 1232

echo:EEPROM version mismatch (EEPROM=? Marlin=V76)

echo:Hardcoded Default Settings Loaded

Testing X connection... Error: All LOW

Testing Y connection... Error: All LOW

echo:SD init fail



2.

i can´t write a new (invertet x and y) Configuration.h File to the Printer...


3.

It is normal that i hear a klick, klick, klick the hole time the printer is connectet with the usb Cabel?


Where is the fault?

thanks and Greets from Germany

Hallo! Wie ghet's?


1.) If you have the TMC2208 upgrade, you have to ensure that you made the change in the firmware to reflect that.

2.) If you have already made that change, then it's related to you not being able to write the firmware file to the printer. Does it give you a specific error when you try to upload the firmware?


No, the clicking noise is not normal. If you have the LCD display make sure that your LCD wires are correct. I had to modify mine by cutting off the little lock tab on one side. https://makertech-3d.dozuki.com/Guide/Stage+01:+Base/50?lang=en#s574

@Pritesh

thanks for you help.

The Display work after cutting the cabel like the link do you postet!


First a question about the TMC2208 Drives:

1 but 3 white boards on the 1. 3 Mainbords sockets (without Jumpers on the Mainboard. 3 Jumpers on the UART Pins.

(Stage 08 Stepping 18) is this correct?

What is whit the 2 last Sockets on the Mainboard? all Jumpers on the Mainborad? Emthy Sockets? 2 Red (A4988 Stepper Drivers) on it?


  1. i have changed the Firmware / Configuration.h file like in Stage 09 Steps 3 to10... is that are the "line numbers" are not the same in my file. (Exampel: TEMP_SENSOR_BED value to "1". on the web page Line 417. in my file line 420...)

  2. Step 4 i have the tmcstepper Version 0.7.0

  3. Step 5 i changed it so: (i have 3

#define X_DRIVER_TYPE TMC2208

#define Y_DRIVER_TYPE TMC2208

#define Z_DRIVER_TYPE TMC2208

//#define X2_DRIVER_TYPE A4988

//#define Y2_DRIVER_TYPE A4988

//#define Z2_DRIVER_TYPE A4988

//#define Z3_DRIVER_TYPE A4988

//#define Z4_DRIVER_TYPE A4988

#define E0_DRIVER_TYPE A4988

#define E1_DRIVER_TYPE A4988

//#define E2_DRIVER_TYPE A4988

//#define E3_DRIVER_TYPE A4988

//#define E4_DRIVER_TYPE A4988

//#define E5_DRIVER_TYPE A4988

//#define E6_DRIVER_TYPE A4988

//#define E7_DRIVER_TYPE A4988


if i upload the new "configuration.h file after 1 min. i get an long error message...

Wherever you don't have the TMC stepper drivers, you need to have the A4988 (red) drivers. Keep in mind that those are installed in a different orientation, as stated in the manual. Those red ones will keep all the jumpers in place on the mainboard (not UART).


It should be on line 417, not sure why yours is line 420. Maybe try re-downloading the file from Makertech. https://github.com/Makertech3D/AXIS/archive/master.zip


Step 4, that's ok, tmcstepper was updated since Makertech made the build manual. I actually have version 0.7.1.


Unfortunately I cannot diagnose why you're unable to write the firmware to the board. I would try again after making sure you have the correct one downloaded from Makertech. Maybe you can find more help here as well: https://marlinfw.org/docs/basics/install_arduino.html

You need to reset the EEPROM. You should be able to get to the menus to do this but if you cannot and can connect via Pronterface then you can issue a "M502", then "M500", and finally a "M501". This will do a factory reset, save that to EEPROM, and then load the settings.

@Pritesh


ok, thank you for your help. I going back an do the Steps new.

Now it works!!! Thank You !!!


Now on Step 21 Auto Levelling...


Can i ask you anoter question? please:


  1. Wenn i Press in Pronterface the Z+ --> the printer goes up! Right?

  2. Wenn i Send the G29 for Autoleveling the printer drives to the front!

and i have this:

SENDING:G29

echo:busy: processing

echo:busy: processing

Error:Probing Failed

[ERROR] Error:Probing Failed


any idears?

Pritesh
Aug 17, 2020

That is the correct behavior for the autoleveling. The probe moves all the way to the front corner and then will move across and probe a total of 20 points.


The Probing Failed is because your Y arm is not level or square with the bed. Get the arm as straight as you can and try it again. Keep adjusting until the probing works.

ok.

I have do the step 18: Homing x and y. Thats ok. it stops after 2 times klicking the "end-Stopper".

than i drive down the Z axis to the right corner. on the Display it ist X: 300; Y: 200 and Z -6.9


How can i Sve this Position for X Y and Z?


Step 19: I think that ok. The Red Light goes on and i can but an normal Paper between the Hot Nozzle and the Printer....

Pritesh
Aug 17, 2020

Even if the red light turns on, that just indicates your probe is functioning, does not indicate that your arm is level and square with the bed.

Saving the positions comes in at Step 23, after you've figured out what your Z offset is.

The Y Arm is in all Position in the Front and in the Back ("Z Arm") at the same High to the Hot Surface...


??? I have the TMC2208 (White Boards) on the x y and z MB... right?


When i send the G28 command the Z "Arm" moves up. The X andy Y moves in the middel.

When i send the G29 command the Z"Arm" moves uo aggain and then

processing

Error:Probing Failed

[ERROR] Error:Probing Failed


???


Pritesh
Aug 17, 2020

Ok, revisit Step 6 and verify the following:

  • When running the TMC2208 drivers you will also need to invert the motor directions for the axes that you have them installed on:

  • Scroll to line 1067 (File -> Preferences -> display line numbers) and set as shown if that axis has a TMC2208 driver:

  • INVERT_X_DIR true

  • INVERT_Y_DIR true

  • INVERT_Z_DIR false


The E1 and E2 should remain false since you do not have TMC2208 there.

ok. i have changed it!

But i have test it... the Y Axe is wrong. After klicking on the Y Home it comes to the "Front" of the Printer (the "Stopper" is on the other side).


So here it is now:


#define INVERT_X_DIR true

#define INVERT_Y_DIR false

#define INVERT_Z_DIR false

That appears correct to me... Unfortunately I am all out of ideas on what could be the cause... Maybe Makertech can help you further.


I will post a video later of what the correct behavior should be when you send the G28 and G29 commands.

One thing to try, and I'm not sure if it makes a difference, is to place one of your additional red stepper drivers in the E1 slot so that all the slots are occupied.

I have order an metal flexebel Shaft holder and i will change it on the Z motor... maybe than it works...


I think if there is a problem with the in vers y x z moves normaly ther shoud not be an error after sending the G29 command....


the order will be here on Friday...

Error:Probing Failed

after sending the g29 command.



I noticed that while testing M119 the stopper / trigger yes all should be open. But z_Min Triggered ... Maybe there is the mistake ... Where is the stopper at Z?


>>> m119

SENDING:M119

Reporting endstop status

x_max: open

It's your Y arm. Front of the printer, make sure it's not off in the left or right direction, but also the up and down direction. That is, the part connected to the Z screw needs to be exact same height as the front of the arm. Also, the part attached to the screw needs to be in a straight line all the way to the front of the arm, in relation to the bed.

So you send G28 and it homes to the center of X,Y. Is that correct? Then it should slowly move down until the light on the probe illuminates. It will move back up and then slowly down. Is this all happening as I described?


If that is happening then I'm confused why the G29 wouldn't work.


I would certainly suggest checking the connection for the probe. It didn't fit snug on my setup so I used some hot glue to keep it in place.

Pritesh
Aug 21, 2020

The Z end switch is your probe. Sorry, I didn't see that part of your message when I replied earlier.


Z triggered means your probe activated. Recheck wiring according to manual. Is the red light on top of the probe active when you receive the error?

@Pritesh


i don't quite understand. I think my english is too bad ... I checked all parts again and also realigned the Y arm. It is the same height at the front and back and does not "tip" to the right or left. But still I always get displayed. I do not get it. Is there a contact for the Z switch somewhere?


@Michael G


home X works home y works. then I move the hot needle all the way onto the hot surface. only 1 sheet of paper fits in between. As soon as the needle is in contact, the red lamp also comes on. Then I give the G28 command and x and y are about in the middle of the plate and the Z arm moves up a bit. nothing more happens. when I send G20, everything moves to the right (starting from the front of the printer) (i.e. exactly the opposite of Home x and Home y. z goes up and then Error ....

but alway if i send the M119 Command:


>>> m119

SENDING:M119

Reporting endstop status

x_max: open

y_max: open

z_min: TRIGGERED

oh ok ... i found the bug ... i'm so stupid ... sorry. I inserted the blue and black cables incorrectly. I plugged in pins 1 and 2. but not how correct 1 and 3 .... Now everything works fine. I'm on the last step now but the red lamp on the heating plate is not lit ... What could be the reason. I turn on 60 degrees and after a while there is a warning tone and the error in the display of the printer ... Any idea? Thank you!

And another QUestion: Where is to installt the PTFE tubing?

Pritesh
Aug 22, 2020

What is the error that is displayed? Ensure the separate heated bed power supply is properly connected (you should see a light on the MOSFET board you installed) then verify the thermistor (really thin wire) from bed is properly connected to the main board.


The PTFE tubing goes from end of extruder motor to top of hot end.

Questions...

The PTFE tubing has on one side a golden nut and nothing on the other side...

i can not finde a picture where i can see it...

Pritesh
Aug 22, 2020

Tubing can be removed from the nut by pressing down on the plastic ring on the nut and pulling the tubing. But there should be one nut on each end when you're done.

Also make sure to insert the little orange plastic tabs/spacers in those black compression fittings. They keep the tub from sliding out by always keeping pressure on the fitting.

Hello again, After I had a defective temperature meter and replaced it, I am stuck with the G29 command again. He makes the first 4 points flawlessly and then he always breaks off. no matter what I adjust or adjust ... Has been going like this for 2 days ... What could that be?

1
Michael G
Aug 31, 2020

Let me make sure I understand correctly the symptom:


  1. Send G28

  2. Printer homes

  3. Send G29

  4. Printer probes the first 4 points then stops


Does it attempt to probe the 5th?

Does it probe the 4th by moving down, then up, and stop without moving?

Does it probe the 4th by moving down and stop when it detects the bed?

At any point does the nozzle contact the bed?
