if masking tape helped with adhesion, you do not have the bed close enough to the nozzle. Very common issue.

what kinds of temps are you running?
Have you properly calibrated your feed rate?
looks like you may need to adjust the vref as well..

I have finished to attach the board to the printer and started some testing.

To resume, what were the important points I went through :

0. I used the https://github.com/ozadr1an/Solidoodle- … in_v1_beta firmware. Not sure that was the best choice

1. Buy some XH-4P, XH-3P and HX-2P female connectors to be able to plug things correctly on the board

2. endstops are plugged differently on the sanguilolu (GND/5V/PIN) and the MKS gen 1.4 (5V/GND/PIN). It has to be plugged GND/PIN

3. X and Y endstops have to be on the max not on the min. Bypass the other endstops. They probably can be desactivated through the firmware but as I am not sure if there are not some side effect, at least it works like this.

4. On the firmware side :

4.a. on Configuration.h I changed :
#define MOTHERBOARD 33
#define SOLIDOODLE_VERSION 2
#define INVERT_E0_DIR true

The extruder stepper was going the wrong way as the X and Y stepper. I did not change the X and Y direction because it seems to create other problem with the rest of the firmaware behavior.

4.b. on the pins.h I changed line 601
#define HEATER_0_PIN       10   // EXTRUDER 1
There is a strange coding here on this version of the firmware between line 598 et 602 ...

5. on the cufiguration in reperter I have put X home at 155, Y home at 150

I did some testing with PLA slicing with Cura and printing with repeiter. It is far from being perfect I need to do some fine tuning. I probably will need some help with the basic configuration for PLA. I have tried different things for adherence, the only one that worked until now is the masking tape ...

The Invert X and Invert Y buttons do not change anything (at least anything I can see)

With this configuration, after hitting the Home button M114 gives :

X:205.00 Y:200.00 Z:0.00 E:0.00 Count X: 205.00 Y:200.00 Z:0.00

and M119 :

Reporting endstop status
x_min: open
x_max: TRIGGERED
y_min: open
y_max: TRIGGERED
z_min: TRIGGERED
z_max: open

I will continue to check the different functions and will come back to give some news and probably ask for more help wink

Thank you all!

this looks correct to me (the X:205 is set in the firmware, btw)

why things are inverted, I do not know, but, I am not a firmware guru by any means.
hopefully someone else with more knowledge of these things can step in and help out.

As for the wrong way X and Y moves I still have no clue (except that is maybe the right way)

Here is the configuration which for the moment makes sens :

The Invert X and Invert Y buttons do not change anything (at least anything I can see)

With this configuration, after hitting the Home button M114 gives :

X:205.00 Y:200.00 Z:0.00 E:0.00 Count X: 205.00 Y:200.00 Z:0.00

and M119 :

Reporting endstop status
x_min: open
x_max: TRIGGERED
y_min: open
y_max: TRIGGERED
z_min: TRIGGERED
z_max: open

I will continue to check the different functions and will come back to give some news and probably ask for more help

Thank you all!

After installing Repieter, i had to configure it.

Then I did some testings, with GCODES.

The first problem was the endstops wireing :
1. the wireing is different from the sanguinololu for endstops : sangui => GND/5V/pin, MKS => 5V/GND/PIN
2. I had to bypass the entries for the max values because without that they were said to be TRIGERED

Now I am facing a problem I can't solve :

The X and Y axis are inverted, and even when say it in the configuration they still go to the wrong way. I don't understand why. When I do  M114, i get : X:0.00 Y:0.00 Z:0.00 E:0.00 Count X: 0.00 Y:0.00 Z:0.00

Repetier does not care what board is attached, as long as things are set up correctly, it should work just fine.

Looking at your connections, you may need to move the endstops for X & Y - they are currently in the MIN positions... SD used MAX..

Things seems ok up to here :

The only thing : I did not find where to plug the LED strip.

Now a very stupid question : How do I test it ? With wich software ?

And before testing with a printing software, I'd liked to be able to send direct orders from the arduino serial monitor to test it. How could I ask the printer to go to a certain x,y,z coordinate for example ?

Thank you for your help !

The motherboard I baught is this one :

http://marlinfw.org/docs/basics/introduction.html

use the ones that came with it for now... you can always change them out later if needed.

Included with the motherboard, there were some A4988 stepper drivers.
Do you think I should re-use the Pololu that were on the sanguinololu board or use the A4988 ? The pins seems to be in the same order.

I think that would be a matter of preference. Either set of chips should work.

I have choosen 33 for the motherboard.

One questions about the hardware :

Included with the motherboard, there were some A4988 stepper drivers.
Do you think I should re-use the Pololu that were on the sanguinololu board or use the A4988 ? The pins seems to be in the same order.

also, make sure the endstops are correctly configured, and plugged in to the correct places on the board...
