Smart Effector issue

[tecno]

Still sporadic trigging, need some rest to clear my head.

I noticed following. when homed and issuing G29 I can observe several triggs with LED flickering.
This even with 55:200.

Also I can see push-down of bed position from 12 to 4 in outer positions.

Something is fishy for sure.

@tecno please answer the first question in my previous post. Also tell us what M558 command you are using.

M558 P8 R0.4 C"probe+servo0" H15 F800 T1500

G29 and tiggers on point where it should go down. Idle = NO

@tecno What do you have in the probe G31 line?

[tecno]

@rjenkinsgb

G31 P180 X0 Y0 Z-0.72

M672 S131:131
1/16th µstep Back to 'normal'

[rjenkinsgb]

@tecno OK; the Z-0.72 reminds me of the smart effector I got that was faulty...

The other one is incredibly sensitive, I initially set it at -0.1 but to get a correct first layer it seems better at Z0.0 !
That's with all default settings.

DC42 is the authority on that, though; I'm just another Duet user.

Try reducing the probing Z acceleration, using M201.1 if you are running 3.4.0RC firmware, or M201 if not. High Z acceleration combined with a high mass hot end create the same strain in the effector at the start of the probing move as nozzle contact does.

@dc42
M201 X1000.00 Y1000.00 Z400.00 E1000.00

Slightly worse = more jump over points

[dc42]

@tecno try even lower, e.g. 100.

Also, if the green LED flashes at the end of the XY travel move rather than at the start of the probing move, increase the M558 R parameter.

@dc42

R1 or R2 Still same problem

[tecno]

No problems with fan shroud taken off.

[Phaedrux]

What does the fan shroud look like when on?

Ah, so quite large then.

[tecno]

@phaedrux

Jay has been using this model without problems, so go figure.

[Phaedrux]

Interesting. I wonder if it's a sensitivity problem then.

I assume it's been disassembled and reassembled already?

[tecno]

@phaedrux

Still as in latest picture = no duct.
Total weight is 84grams with 3 fans, printed in PETG.

[jay_s_uk]

@phaedrux that duct design (which is mine) works fine for me on my smart effector v3 so i doubt thats the issue. I still think its a mechanical issue with effector tilt

[tecno]

Have found my main issue = the printed effector adapter is way too small = too short rods.

Back to the drawing board!
