I'll try myself..

You could always email them directly: [email protected].

Search my posts as I mentioned earlier.

You will need to change at least the following:

Configuratio_prusa.h:

#define DEFAULT_AXIS_STEPS_PER_UNIT {100,100,3200/0.8,174.2} // the 174.2 will need to be around 522.6

Configuration.h:

#define INVERT_X_DIR false // for Mendel set to false, for Orca set to true
#define INVERT_E0_DIR true // for direct drive extruder v9 set to true, for geared extruder set to false

The X_DIR value will need to be true; the E0_DIR may need to be false, but you will need to check this out. Won't do any harm if it's wrong, will just feed in the wrong direction.

You may need to change the following:

Configuratio_prusa.h:

#define DEFAULT_MAX_FEEDRATE {500, 500, 3, 25} // (mm/sec) - the E value (25) may need reducing to (say) 10

#define DEFAULT_PWM_MOTOR_CURRENT {270, 450, 450} // {XY,Z,E}
#define DEFAULT_PWM_MOTOR_CURRENT_LOUD {540, 450, 500} // {XY,Z,E}
In both the above lines the E value may need to be increased, depending on the feed quality; you could go to up to double the values (900 and 1000) if you have feed problems.

Hope this helps...

Re: Titan Extruder probelms

I try to compile the code on arduino ide
but i get this error

Re: Titan Extruder probelms

Did a quick search of my posts and found this:

I did a quick search of my posts for "repository" and found this:

1. Download the latest Arduino IDE from Arduino.cc
2. Open the IDE, open file/preferences and set additional boards manager to the RAMBo repository: https://raw.githubusercontent.com/ultim ... index.json
3. Open Tools/Boards/Boards Manager and install the RAMBo board.
4. Close the IDE.
5. Unzip the Prusa firmware source code and follow their instructions for your board.
6. Open Configuration_prusa.h in a text editor (Notepad++) and find the line:
#define Z_MIN_POS 0.23
7. Remove the ".23" from the end of the line
8. Save and close the file
9. Double-click the Firmware.ino file - this will open the Arduino IDE
10. Connect the printer, compile and upload.

Points 6 and 7 need to be amended for your particular requirements.

Point 5 requires the LCD libraries to be removed and the copying of the correct variant to the primary firmware folder.

Between points 9 and 10, you should select the RAMBo board (installed in point 3) and port.

Did you exactly follow the instructions above?

I have had a further read of the E3D web site:

Owners of Prusa i3 machines purchased directly from Josef Prusa himself please note:

Josef Prusa chose E3D as the new hotend of choice in late 2015 and ships Lite6 with the Original Prusa i3 kit. Full V6 is drop in compatible and can be purchased, precompiled firmware for Full V6 is available for download. Titan requires user modification of stock firmware settings.

My interpretation is that they are saying that the Titan is for i3 clones; for the "original" you only need to purchase the V6 upgrade (should you so desire).

So the question is this: Will you continue with the Titan or simply replace the extruder?

Re: Titan Extruder probelms

I had found a different post

but now i try to follow this
instructions

one questions i got an hex file..
this file don't open with text editor

i'll try to use the titan...

Re: Titan Extruder probelms

I don't understand why you have a hex (object) file. You need the source files.

Have you learned C++ programming yet? If not, then what you are about to attempt could cause serious damage to your printer.

Re: Titan Extruder probelms

Any reason not to just plug in the x-carriage motor connector in turned 180 degrees/backwards?

The RepRap wiki ( http://reprap.org/wiki/Stepper_wiring ) says this:

Plug it into the stepper driver
To get the stepper just moving, polarity of each coil doesn't matter, nor does it matter which coil is which. So make sure each pair of wires for a coil are together on one side of the plug (or the other side for the other coil), and plug it in.

And then:

Motor moving the wrong direction
To get the motor moving in the right direction, is actually does matter which coil is which and what the polarity of the coils are. However, if they're wrong, the motor just turns the wrong way, it's easy to fix that by swapping wires. Pick one of the following in order to reverse the stepper's direction:
[...]
4. Plugging the plug in backwards (in case your electronics' plugs allow that). This swaps the coils, and reverses both coil A and coil B. Thus the effect is to change the direction 3 times, which gives a net effect the same as changing the direction once. Only few electronics allow that, because you have to figure the right way not once, but each time you connect the stepper.

I just did that and it reverses the motor as expected.

So I take it that the connector just needs to be plugged in backwards (same for the extruder-motor, if it should turn the wrong direction). No need for firmware modification there.

After that the E-step value can be set by gcode.

If the extruder-motor current set in firmware is high enough, then theres no need to change the firmware at all!

My connectors are polarised, so it would require quite a bit of fiddling around to get the connectors correct (and without breaking anything...).

The Titan motor is rated at 1.7 Amps; the original extruder motor is rated at 1.0 amps. The extruder motor is already being driven at less than 0.5 Amps, so it may be necessary to increase the motor current in order for it to feed properly.

Sure, but everyone else who bought the kit won't have polarized connectors and should know that this particular step won't require firmware modification.

(Or maybe I'm wrong and there are different versions of connectors on the kit out there?)

The extruder motor is already being driven at less than 0.5 Amps, so it may be necessary to increase the motor current in order for it to feed properly.

Yes, that will need testing

Re: Titan Extruder probelms

i downloaded the firmware from prusa
when i unzip the file are all in .hex

Re: Titan Extruder probelms

i'm going to

https://github.com/prusa3d/Prusa-Firmware/blob/master/Firmware/variants/1_75mm-RAMBo13a-E3Dv6full.h

and paste on text editor

after that to trasfert to my printer i need the arduino ide?
right?

Re: Titan Extruder probelms

the e3d support :

Hi Amerigo,

Thanks for the email

I have spoken with our engineers and they have told me that the solution to this problem is to disconnect your motor from the board and re connect it the other way around.

If this doesn't work then please let me know.

Kind regards

Lawson

Re: Titan Extruder probelms

Hi amerigo.p,

did it work when you reversed the cable? plz advise

Yazeed

Re: Titan Extruder probelms

Yes the problem solved

And i have added by gcode the right STEP FOR MM

Re: Titan Extruder probelms

Sorry to revive an old thread, but how has your Titan extruder been? Have you felt it was worth the upgrade?
