smarteffector v2 sensitivity not stored

[dc42]

@apak it sounds to me that the firmware on the effector needs to be flashed again. Which country are you in? Do you have any equipment that can program an Atmel 8-bit microcontroller?

Is the reason for reducing the sensitivity because there is vibration that causes it to trigger unexpectedly, or is it triggering at the start of the probing move? If the latter then you may be able to suppress that triggering by reducing the M201.1 acceleration of the Z axis.

@dc42 I live in spain. The reason to change sensibility it´s because It triggers with any slight touch or movement so it does not trigger as it should. It´s my only smarteffector that ever has this behaviour, but I just got it from a old abandon printer that I am rebuilding.

It also triggers with a fan turn on.

In this case I have two diferent smarteffector, one with volcano and this one with a V6, and this is the only one with problems.

The predator and a v2 also with volcano and no troubles .

Already have low Z acc wih M201.1

M201.1 X500 Y500 Z500 E500 ; Set accelerations for special moves (mm/s^2)

Also I am going to buy this and try to update fw on board

@dc42 can you confirm me, what version of fw from https://github.com/Duet3D/SmartEffectorFirmware/releases should I flash to this board.

thanks in advance

[dc42]

@apak use 2.13. Choose the binary for the version2 hardware.

@apak and what app and board should I configure asuming I have a arduino UNO

also have this little fellow

[dc42]

@apak there are several videos about this, search for "Arduino as isp". For example, https://www.youtube.com/watch?v=TtC6crf_EP4 (this is not a recommendation, I haven't watched all of it).

@dc42
I didn´t wait for the popo pins to arrive, so I soldered some pins and used a Arduino UNO as Arduino ISP Programer, with avrdudes and upload he .hex file you mentioned.

At detect (before uploading) it had a checksum mismatch, but I forced the upload and had that log below.

Is it there and way to know what version of fw it uploaded on a smarteffecto?

How could I know it was flashed ok? Maybe with a new M command such as M672 S99:99 that was included in fw 2.13?

I was only able this morning to plug the 8 pin plug and the smarteffector flashed 2 times, but couldnt test any more, had to leave to work

@apak Update, It did not flash ok. I set a sensitibity other that stock, power cicle and only 2 led flashing

[apak]

Succesfully updated to 2.13 and solder pad restored

thanks

@apak Well done! What did you change to get it to flash? And does it now store the sensitivity?

@droftarts i didn’t use the arduino uno.
Now once changed sensitibity, if power cicle led blinks 3 times

Will upload tomorrow destiled instructions

@droftarts

Recap: Old smarteffector v2 that does not remember sensitivity custom settings.

Solution: Flash new firmware V2.13 via PROG pin pads on top board side.

Procedure: Solver pin strip to exposed pads and use a direct pin to pin cable from the ISP port on programer

Programed with a FT232r programer with AVRDUDES app
