Re: again opto endstop dilema Felix 3.0

Post by Patrick »

The replacement control board came today including the missing springs and two replacement opto endstops just in case.
The control board is version 3.1 now. What should I say...
It didn't work. The same issue as on the other board. Even with the new endstops and all.
First I connected the printer Repetier Host get no proper connection and the printer didn't response on movement instructions.
I had so upload the las firmware to take care of that.
Now I'm really confused I double checked all of the wiring and the printer looks now like a mess with all the cables.
I would really apreciate any advice here.
Perhaps from a specialist from Felixprinters hopefully?

Hi,

This is very strange, it seems that everything is tested. On the older version boards some 2.1 boards, the opto sensor circuitry had a slightly different resistance value, which sometimes caused troubles. Are you sure that the opto wiring is correct?
So when you move the table into the opto-slot the light of the y-axis goes out? If this is not the issue, then the only thing we can do is to send you a control board with proven to work opto-sensors. Hopefully that will resolve the issue. We would also like to obtain your control board including opto-sensors to examine it further and provide feedback to the electronics factory.

Kind regards,

Guillaume

Hey Guillaume,
today I made a new discovery. I used the display instead the Repetier Host software to move the axises.
Now I'm sure the opto endstops are working. It ist clear to see in the display, but they are not doing anything (but the z-endstop) to the movement of each axis.
I could provide a video, but I'm not allowed to upload it to this forum.

Hi Patrick, can you in some other way send me the video, perhaps dropbox? This behavior is new to me...

Hello Guillaume,
here is the link to the video. You can hear the movement of the x and y axis in either direction regardless of whether the endstop is triggered or not. The z axis stops the movement in minus direction when the endstop is triggered.

Silly thought here - but have you made sure that all of the wire insulation is peeled back enough so as to not be pinched in the terminal blocks? I'm speaking from experience unfortunately. They are tricky and sensitive little suckers. It must be pure wire locked in place with no insulation for a good contact. I see in your pictures that solid metal wiring is not visible in some of your leads which makes me suspicious. Also be sure no single strand of any one wire is sticking out and making contact with the neighboring wire.

Hi,
every thought could be usefull.
I've double checked the wiring very carefully. If there would be any conection problem with the stepper motors, they would move strange or not at all. But all of them move smoothly.
For the other conections I can say, ervery thing works fine. The heater, the temperatur sensors the fans.
My last hope is the support from Felixprinters to get the printer to work. Otherwise the reseller made me the offer to return the whole printer.
This would be the last option :-(
regards
Patrick

I think it is pretty clear from the bug history and from the video that this is not a hardware problem. Obviously, the controller can read the optos and controls the motor. What happens if you run the home command? Perhaps you should try to download and reinstall the firmware once more an make sure to reset the EEPROM to the factory settings (safest way is to change EEPROM_MODE in Configuration.h to some higher value, e.g. 77, before compiling and uploading the firmware).

Hi,
I'm a little afraid about homing the x and y axises because of the risk of a mecanical damage.
But I'l give the firmware suggestion another shot and try with a EEPROM_MODE change.


That's it!

I reinstalled the firmware with a different eeprom position.
Than I had tried to home the X axis.... and it worked. Yeay!
Now I can home all axises. Tomorrow I will give the printer some more tests. Actually I haven't extrude a single bit of filament.

Thanks

Hi Patrick,

Good to hear you found the fix. Did you manage to do some printing?

@ Dreide: Thanks! This was a good tip.

Kind regards,

Guillaume
