dc 42 ir sensor problem?
-
@Veti give me 20m to get home and do that macro..
What I told until now is what happen since I bought the sensor...
Worked 1 or 2 times... Then repeat the same process and doesn't work... -

@Lc1975 said in dc 42 ir sensor problem?:
-0.376
is that at the position where you homed? it should be close to 0.
-
@Veti
Yes that's the Z0After change to a new black card sheet..
03/11/2019, 15:29:55 G29 36 points probed, min error -0.364, max error 0.352, mean -0.054, deviation 0.169 Height map saved to file heightmap.csvI think that this is the first time that i have made a G29 without problems....
-
My mistake.. Thinking that problem was solved......
Doing other Bed Leveling with G29 without touching in nothing...
Bam.. the nozzle hits the bed and no trigger from dc42 irI don't know is is normal...
When doing the bed leveling the sensor in DWC on the "sensor" rarelly appears numbers even when the light is trigered..
I saw maybe 3 times "1000" then almost always "0"Normal?

are you using 1000? as a trigger value? if not slow down the probing speed. if so use a lower value.

@Veti
No...
I have this:; Z-Probe
M558 X0 Y0 Z1 P8 H5 A2 S0.08 F200 T4000 ; enable Z probe but set dive height, probe speed and travel speed
G31 P500 X0 Y13 Z0.03 ; trigger the probe
M671 X50:250 Y60:250 S50 ; define mesh grid -
use P1
see
https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probeMini differential IR sensor by dc42
Connect the VCC, GND and OUT pins of the sensor to 3.3V, GND and IN respectively on the Z probe connector, and select mode 1
-
@Veti
tried P1
same result...
Just triyng to see if other results.. -
The first picture was the first probe G29
And here the sensor showed "0" in DWC
This one was after a 1h +/-
This one hit the bed... And the same here.. Showed "0"
And after reboot and move axis to the same place and manually Z0 the nozzle the sensor trigered...
And doing a G30...
Stays ok and the sensor shows "1000" -
have you tried the test without the glass?
-
Yes...
Same result...
Painted with mate black and no paint...
This moment has a black mate papper under the glass.. -
After a G30
I do this:
G30 S-1 stopped at height 0.064 mmThen i use the macro that you told me to use.. And the result....
Hit the bed! -
does the led blink on the first and not on the second attempt?
-
@Veti
wait a moment.. i made a little video with this order:
G28
G30
G30 S-1
Then the macro...
And when use the macro hits the bed...
Just uploading to ondriveHere is the link of video
printer sensor problemAs you can see the Z-Probe is always between 5 and 1000 in DWC
-
G30...
G30 S-1...
G28..Works well...
Doing G29 or a G32 or the macro
The sensor won't work..
Or it can work..
1 in 10 times
Using
Board: Duet Maestro 1.0
Firmware: RepRapFirmware for Duet 2 Maestro 2.04RC4 (2019-10-19b1)
Duet Web Control 2.0.4 -
hmm. other than a bad a crimp i have no idea.
-
Almost quit from using this...
Maybe reverse to marlin or quit for good this kind of hobby.... -
maybe the ir sensor is faulty. @dc42 what do you think?
-
I reduce the speed of Z to 1mm/s with cold bed and then other with 70ºC
have a reading of the Z-Probe 33 times was 469 and 3 times was 539
And until now.. No hiting the bed...
Maybe was the speed the problem...?
