Did some one use this hotend ? i try to find bracket for this but i didnt find something who is correct for the Pro B i3 Geeeetech printer.....

For Rev A+ boards what it needs in firmware to change ?
I ask because i have this borad GT2560 A
Thanx alot

If i remeber well wen they send me the sensor there it was a couple of ressistor is any there extra connection for this ??

i do all from the start i use the frimware for acrilyc prob2 and the same problem i desolder evrithing and resolder from the start!

It start to do the measurments and wen in go to the center the sensor go down to the middle and stucks to the bed really i dont unsterstand what happens did some one ...

The same i did manually i get the preUpdatet version but nothing happent i can get any message or to see any error command g28-g29 its works the rest not and the led is not blicking my board is gt2560 a
check it all im pretty sure the firmware is buggy to make also some axis to work i revert it ...

i follow this http://www.geeetech.com/Documents/3DTouch%20auto%20leveling%20sensor%20%20User%20Manual.pdf
And its looks ok i measure it with multymetere and i dont find something wrong
Im pretty sure the problem is from Firmware .....

Here is my connections on board

Zmin

black

Zmax
red ...

If i give G28 or G29 command its starts but the sensor it seems not working it goes to the middle and wen the Y axis goes down to calculate the center path it goes down till extruder touch the bed!

so i have to check again the connections?
If inst connected properly.. wen i open the printer it make ...

I did everything twice time i check it alot of times
Something is going wrong but i dont understand what
My problem is i open the printer its starts makes 2 time up down up down no error no blinking led
I try with command G28 and is not stooping wen touch the bed i make emergency stop i try to use ...

It works now thanx
