Marlin Delta Firmware Issue

I have downloaded and put the new config_adv.h into the marlin folder.

When I get to the office tomorrow I will try again.

If this doesn't fix it I don't know what will!

Repetier firmware might work!

If that also does not work it is a hardware problem...

Hey,

I tried Repetier Firmware once and for the life of me I couldn't get it to work!

Just discovered something very odd!

[forums.reprap.org]

Could this be the reason why?

Thanks

What happens when you home twice?

I would expect that it goes through the same motions twice,
if the motors don't move the second time, it can be a short-circuit...

Can you attach a photo of your board that shows how the wires are connected?
Perhaps somebody who owns a Ramps board recognizes something strange..?

Here are the images of my Ramps 1.4.

Also I can do G28 as many times as I want and it still homes perfectly!

Your hardware config looks good (to me...)

I am going to try Repetier on my Kossel mini this weekend,
do you remember what your problems were with Repetier?

---

RS-Online Ormerod #263, Kossel mini with Minitronics, Prusa i3 MK2

Yea,

For some reason, I could not get it to home!

I kept on getting this message when i tried to home the machine:

Warning:Invalid delta coordinate

And nothing moved at all!

After you home your printer it does not want to move down,
have you tried to move it up? Just to see what happens?

Okay, So when I do G28 then G1 Z300 (Max should be 250)

The printer doesn't move but when I send M114, the Z is at 300. Which is shouldn't be!

I have attached a screenshot of this.

EDIT:

I have max_software_endstops set to false. Hence why it can happily go to 300

This is so strange...

Your printer moves repeatedly to X0, Y0, Z250 when instructed by G28,
but it refuses to move when the move is started by G1, but updates Z.

What are the differences between a G28 and a G1 move?

Perhaps it has something to do with the feedrate?

G28 homes with a feedrate set in Configuration.h
G1 uses a feedrate setting that can be changed...

Perhaps something overwrites the default feedrate used by G1?
You can try to specify a feedrate for the move: G1 Z200 F4000

Hmmm, that is a good idea!

I won't be able to gain access to the 3D Printer until Monday sadly!

I have a few Ideas to try and narrow down what it is.

I have a spare Ramps 1.4 shield which I can swap to see if it is the shield.

I also have an old Sanguinololu board somewhere, but the location of said item is proving to be tricky to locate!

With any luck I will have a few fixes to try on Monday.

I would like to know how you get on with Repetier Firmware this weekend!

Thanks

My printer is printing with Repetier firmware at the moment, looking good!

I have made a log of the things I did to get it running,
I will post it here when I am done editting and translating!

RS-Online Ormerod #263, Kossel mini with Minitronics, Prusa i3 MK2

Hey,

I am glad you got it working!

And I am extremely grateful that you are logging the issues and errors + fixes.

and Good News!

I have found my Sanguinololu Board!

I will have a play on Monday and it should work as it worked with my old cartesian printer.

If it doesn't work I know it is firmware.

If it does then it must be the Mega or the Ramps shield.

And I can test the shield with using my current shield from my current printer.

So, with any luck. I should know what is broken by the end of tomorrow!

Thanks

Well this has made my life a lot harder!

My Sanguinololu board doesn't work!

It has exactly the same issue as my Ramps 1.4.

What the hell is going on?!

If you have EEPROM enabled, it can contain corrupted settings.

M503 shows you the current settings in EEPROM
M502 resets the settings by loading firmware defaults
M500 stores the reloaded default values in EEPROM

Perhaps you can try giving it a reset after that, just to be sure...

GOD DAMMIT!!!

I had a number wrong in the Printer Set-up.

I had put 29mm rather than 92mm

29mm is an Impossible value, hence why it crashed when i tried to move it!

ARGH!!!

Here you have my first version of the Repetier log:

Printer type: Kossel mini without probe
Firmware version used: Repetier 0.91
Hardware version used: Minitronics 1.1

Used internet resources

This is the official Repetier installation manual
This is the archive I have installed on my printer
This is a youtube video that shows some steps
This is a blog of another Marlin-Repetier conversion

Edit Configuration.h and pins.h

I did not know which settings were stored in EEPROM,
so I made sure there were default values for everything.

This is the list of changes I made to make it work:

Configuration.h:643 The stepper connectors are not reversed

#define INVERT_X_DIR false

The compiler gave me the following error messages

Printer.cpp:651:2: error #error You have defined hardware x max endstop without pin assignment. Set pin number for X_MAX_PIN
Printer.cpp:661:2: error #error You have defined hardware y max endstop without pin assignment. Set pin number for Y_MAX_PIN
Printer.cpp:671:2: error #error You have defined hardware z max endstop without pin assignment. Set pin number for Z_MAX_PIN

It is time to edit pins.h!

I could not open pins.h in Arduino and used an external editor,
I had to restart Arduino to get rid of that compiler error...

In pins.h I searched for "MOTHERBOARD == 702" (Minitronics)

Pins.h:1717 Swap MIN and MAX pins, delta uses MAX endstops

#define ORIG_X_MIN_PIN -1
#define ORIG_X_MAX_PIN 5

#define ORIG_Y_MIN_PIN -1
#define ORIG_Y_MAX_PIN 2

#define ORIG_Z_MIN_PIN -1
#define ORIG_Z_MAX_PIN 6

After that I could compile Repetier firmware and upload it.

M500 - Store current settings in EEPROM

M502 - Reset settings to firmware defined values

Correcting endstop offsets (without a probe)

It is very difficult to position my endstops exactly,
I have chosen to correct the differences in software.

This step took some time, the usual way to do this is with a probe.
If you use a bed probe then you can probably skip this whole step.

It turned out to be very easy when I found out about G131 and G132

- Run G28 to home all axis
- Run G131 to set extruder offset position to 0
- Run G84 to disable steppers until next move
- Place a ruler under the carriage
- Move the carriage down to the ruler
- Repeat this with the other two axis
- All axis are now on an equal height
- Run G132 S1 to 'home' and count offset steps

Tower 1:0
Tower 2:0
Tower 3:6

These values are directly applied in memory,
With G132 S1 it is also stored in EEPROM.

For backup I also updated the value in the firmware.

Correcting Z_MAX_LENGTH (parameter 153)

I did this by measuring the Z distance after homing,
my Z refused to go below 0, so I 'faked' the height.

Set the maximum Z height to beyond the actual limit:

M206 T3 P153 X260

Move the nozzle down to the platform and do the paper test.
M114 tells the current Z value: Z = 4.7 -> 260 - 4.7 = 255.3

Store the adjusted value in memory and rehome to check again:

M206 T3 P153 X255.3

Correcting PRINTER_RADIUS

This removes mountain / valley error in XY moves.

If PRINTER_RADIUS is too low the nozzle moves 'over a mountain'.
If PRINTER_RADIUS is too high the nozzle moves 'through a valley'.

Tweak Configuration.h until the nozzle moves straight in XY direction,
use the paper test in the center, move in X and Y direction from there.

Hope you get this working, let me know if you have any questions!

Now you point your finger to that very specific spot, I see it too!
92 is still a low value, but perhaps your printer is smaller than mine...?

RS-Online Ormerod #263, Kossel mini with Minitronics, Prusa i3 MK2

Yes, my printer is very, very small!

And thanks for that log you did!

If I get any errors I think it will come very handy!

Thanks

Please help,
I self made a delta type printer, 3 endstops on top of each axes,window 7, ramp 1.4,arduino mega 2560,Reprap discount full graphic smart controller
Then I use marlin firmware (replace the configuration and configuration from the marlin "example_configurations" >Delta through the "Visual Studio Code" and copy the entire file to paste onto the marline firmware configuration.h and the configuration adv.h)
Compile Ok,upload Ok,but it move "autohome" at beginning ,many time trial later,it move but only one axes not all three axes move toward at the same and to hit the endstops,
When I move them manually to a random position and press print from the SD card it move looks normally,and after it run through to finish,then stop at where it is.
Anyone out there can instruct me to "PRINT"
Help! Please
