Z-Probe dig into bed
-
Hi Guys,
I did a search on the forum but couldnt find anything similar to my problem
I got a fusion3 f410 printer with duet3d ethernet board and the automatic bed leveling stopped working suddently. The probing is done by electrical connection from the 3.3v of the board going to the hotend, slowly closing up distante to bed until it toutches aluminium foil tape wraped under the bed that toutches aluminium sheet and ground to the board
Nozzle is perfectly clean, tape is in perfect condition (changed it after the probe digged into it)
What I checked so far :
Electrical loop from the connector out of the board is fully closed when the nozzle toutches the bed. Got 0.5ohms
Thanks for your help!

What port are you using on the board?
Can you post the results of M122 and M98 P"config.g" as well as the contents of your config.g and homing macros just for a sanity check?
It would seem to me to be a wiring/continuity issue.
-
@phaedrux thank you I will check that on monday
Just so you know I also tested the following, continuity at the connector when unplugged fron the board and probe toutching the bed: all good
With power on, probe in the air grnd to nozzle a have 3.3v
There are resistor in the connector on the board, they read 4.7 and 10k if I remember right
I'll get result of what you asked early next week, thank you for your help!

Here is the config.g and output commands as file

Can you also send M115 to report the firmware version? It appears you're using a quite old version.
-
Here it is
M115 FIRMWARE_NAME: RepRapFirmware for Duet Ethernet FIRMWARE_VERSION: Fusionware 1.18.1 RC2 ELECTRONICS: Duet Ethernet 1.0 FIRMWARE_DATE: 2017-05-15 -
Yes that's quite ancient. However, I don't think that's the issue at hand.
There must be an electrical issue. Do you happen to have a normal endstop switch you could connect to the same port to test with?
As I'm not at all familiar with the Fusion printers am at a bit of a loss. Do they have support options as well?
-
There is no normal endstop, the bed stop about 1cm before the nozzle, slow down until it toutches to calculate z-height
I'm on support with them, they say its the wiring harness or the pull up resistor BUT the wiring harness loop got conductivity and the pullup resistors are giving me 10k and 2.2k so I doubt its the issue.. I feel its the board
-
Which connector on the board are you using?
-
The one labelled "probe"
-
Got a little of success here, if I bypass the whole loop with a jumper wire while probing, the board get the connection and is going to the next step
That means the issue is in the wiring between 3.3v out of the board "probe" port after the pullup resistor AND before board probe input
Must be something with heat or vibration as the loop was "good" with ohmeter
Thanks for your help, I'll keep you posted

Looks like the thermistor is the culprit even while its still working
Noticed I had 3.003v at the board but 3.297 at nozzle to bed, figured out I must have voltage leakout somewhere, unplugged heater didnt change, unplugged thermistor triggered heater fault but voltage dropped to 3.003v as the board output
Ran a bed leveling without thermistor and its working!
Need to find out what type of sensor they use to change it!
-
Done deal, swapped the thermistor and everything works flawlessly now!
