You can attach your firmware you use on your RampsFD
So I check that my problem is a FW or nature HW
My problem is that I can not read the temperature read and hotheaded

The sensor is OK because if I try on Ramps 1.4 reads well

Ok Thanks indeed there tava an arrow pointing to Enable and I have noticed

Now unfortunately shot two DRV 8225 were burned but otherwise everything OK

Now I have another problem on temperature probes They read semrpe always up 140 ° C

You can attach what you are using now?
so I check if loaded on my card works all
and especially the temperature sensor

I have a card-FD Ramps v1a with ArduinoDUE

Printer type Cartesian type Prusa I3

FW Used Marlin4Due portring Kimba http://marlinkimbra.it/

I also tried RepiterFirmware
but I prefer to Marlin

I include photos of my current installation

Thank you

Also I'm having a lot of problems with this card

For switches I solved it seems that the word min max is reversed
It must be enabled by FW resistance PollUP

I have a big problem I go thermistors are 100k
Ramps on 1.4 work on ramps FD-1a I always read 140 ° C

Good Evening

I have no movement of motors and read the wrong temperature

Use Ramps FD V1a Arduino TWO and Drivers 8825
I verificarer if the Jumpers and the drivers are installed correctly
Place two photos.

Thank You

Sorry for mistranslation
The Ramps FD V1 Rev A is very old
I wondered why you do not produce and sell the new model Ramps FD 2 Rev A
Ramps FD 2 Rev A https://github.com/bobc/bobc_hardware/tree/master/RAMPS-FD

Well problem solved we can feel the discussion is closed.
One last question because you do not produce and sell Ramps FD V2
And it continues to produce and vednere only Ramps FD V1 Rev A?

thanks

Bene problema risolto possiamo ritenere la discussione chiusa risulta.
Un ultima Domanda ...

Contacting the programmer MarlinKimba http://marlinkimbra.it/
And we are doing various tests we have solved
Probably 74hc4050D on the LCD module is too slow
Arduino DUE you should use a component faster
for now slowing the writing on the LCD and SD works
