Home does not work/motors are not moving. Only a quiet high sound you can hear.

baud=57600, drop down=”new line”.
message from robot says “hello world!”
type D11 and hit enter: messages appear.
type G28: robot goes NOT home.

[raphmann]

Here you can see the sound, when homing with the new board. Motors are not moving:

Yes, sending D8 is L1011 R1011.

1. Problem new board: robot does not home or move. Micro servo does not work.

2. Problem “Old” Board: Robot does home, but micro servo does not work (That´s why I bought
a new one.) Why does the servo not work? What could I do?

[raphmann]

When I tpye G28 the robot goes not home. I only hear a sound, but the motors
do not move.

With the old board I do not have this problem. The Steppers are moving/working.
Only the little micro servo does not work. With the new board the micro servo
does alos not work.

What could be the reason for it?

[raphmann]

One more question:

I´ve plugged in the “old” (=Originalboard) again. But the new micro servos do not work anymore.
Do you know any reasons, why they give up work? I thought the Board has a failure (perhaps got to hot).
Thats why I replaced it.

But if you could have a short guide (EEPROM, D11, D7-D9) I will try it.

[raphmann]

How can I do this? I don´t know, what EEPROM or what D11 or D7-D9 is.

Do you have a short guide for me, what steps I have to do? (I´m not a coder…)

Thanks

I´ve changed the board and installed the firmware. The display shows:

X 0.00 Z 90.00
Y 0.00 F 100%

But the motors are not moving when I type “Find Home”. I only hear a high sound. It´s not loud.
When I press “Stop” on the control board (display), the sound stops.

What can I do?
Also the little servo does not move 🙁

Hi Dan,

is this the right board?

… the voltage of the board for the servo is 4,48 V. I think this should be normal?

[raphmann]

Dan, I need your help.

I´ve bought new Tower Pro servos. They are identical. But when I connect the new one,
the numbers on the display disappear! And the servo gets very hot and it smells a little
like electric fringing.

I suppose the old one gets damaged cause there´s something wrong with the rumba board?!

I urgently need the drawings from the robot, please could you give me a hint?

Raphael

[raphmann]

All those tests failed. I ordered a new servo.

If it´s not the servo, but the arduino – where can I buy one in Germany?
Which one is the right model?

When I open a svg-file in Makelangelo, I would like to save it as dxf. When I
open this dxf-file in Makelangelo again (I would like to use “DXFOptimizeOnLoad”), no
image or drawing appears. In the lower field of the Software there is written:

FielTypeDXF2…
Converting temp 1258299040791194320.ngc
Done!
3 line segments.
28.300001cm
Estimated draw time 0s
Completed

[raphmann]

dxf-export has a bug.

A script to sort ngc-code would be perfect.

Would it be possible to get such a function via firmware update?

[raphmann]

It´s not possible to click the LCD panel when drawing from SD-Card. There´s no
menu option for “Pause / Unpause”. This is only available when drawing per USB, but
that was not my question. Or do I overlooked something?

You mentioned M226. You mean this one? https://www.evike.com/products/34647/
That´s not possible in Germany… 😉

[raphmann]

Yes, it´s controlled by the software. I have tried to change the order in Adobe Illustrator,
but it did not work…

[raphmann]

Here you can see, what I mean:

[raphmann]

YEAH! That´s it. Now the menu works.

[raphmann]

Ok, as you answered me per mail, it is actually the right board yet.

You asked me: “Why is one of the ribbon cables (grey with red stripe) turned around? they should both have the red stripe on the same side.”

I did not turn it around. Which one do I have to turn, left or right?

[raphmann]

I have looked at your link. The BIQU Rumba for 3D printer motherboard is the one I have!
The only difference: the jumpers are at another place and the Mini-Circiut-Boards are red
instead of blue and they are less.

Obviously you have send me a Makelangelo 5 with this wrong board.

[raphmann]

So, I have sent the photos to your mail: [email protected]

[raphmann]

Well, I haven´t changed the board! How can I send you the images – per Mail?

[raphmann]

These lines ar printed on the backside of the board:

Make: BIQU
Bord Model: RUMBA
OPEN SOURCE
3D Printer Electronics

MADE IN CHINA

[raphmann]

First to say: I got it from you! You sent me that machine, after the Makelangelo 3.2
did not work. We had an exchange – I hope, you remember? 🙂

Now I try to find out make and model – but where can I find it?!

[raphmann]

Control board: What information do you need?

This morning I was at our electronic store and I bought a new supply, but the
behaviour is still the same: Rotating the knob leads to blinking on the control board.
