it fails to upload the firmware files

the results aren't much different

Number of points: 277
Probing radius: 185 mm
Probe area: 1075.2 cm²
Maximum deviations: -0.870 / 15.173 mm
Mean error: 7.258 mm
RMS error: 4.668 mm

bed.g is G32.

What order are you running things? There should be G28 to home the towers, G32 to do an auto calibration, and then G29 to map the bed surface.

@Lihyon Looking at the errors in your results, one point is measured 15mm above the z=0 datum!

In your bed.g, you need to uncomment the M561 to make sure you don't have mesh compensation enabled when ddoing the calibration. if you don't it will be calibrating a mesh-compensated bed and you'll only bake in the errors you're seeing in your heightmap.

@Phaedrux i found my biggest mistake so far, its silly

M665 R190 L440.35 B190 H415                           ; Set delta radius, diagonal rod length, printable radius and homed height

R is supposed to be R230.6.
and i was running M561 - g29 s2 - g29 - g32 but i guess im suppose to do g32 - g29 so i added g29 on the end of my bed.g for now

now im facing this issue that the probe doesn't trigger at some point and runs into the bed but not right away like halve way through probing

21.3.2021, 22:02:40	Error: Z probe was not triggered during probing move   while g29
21.3.2021, 21:58:29	Z probe trigger height set to 0.018 mm                  G30 S-3 included in bed.g
21.3.2021, 21:58:28	G32
Calibrated 8 factors using 16 points, (mean, deviation) before (-0.643, 0.353) after (-0.000, 0.037)
Auto calibration successful, deviation 0.037mm

@engikeneer but M561 disables any existing bed compensation or not?
EDIT: well i tried and didn't make a difference

Maybe a sensitivity issue?

Lihyon

setting the sensitivity just doesn't work its suppose to blink 3 times when changed but does not

example
M672 S105:25:255

i found the firmware for it but im struggling to find out how to use Atmel Studio 7 to compile it or upload it

https://github.com/Duet3D/SmartEffectorFirmware

Phaedrux

How old is the smart effector? Does it have a revision number on the PCB?

What does it respond with if you send M672 by itself?

Lihyon

its says pcb Revision 2.0 CERL OHL 1.2 on it
and M672 spits out

Error: M672: No program bytes provided

You don't need to build it, you can download the .elf or .hex file from the release at https://github.com/Duet3D/SmartEffectorFirmware/releases/tag/2.01.

I've noticed oddities with changing the sensitivity of the smart effector. At times, the smart effector seems to lose the sensitivity setting (often after a reset or power off/on) and it has to be set again.

When this happens, about 50% of the time sending either the "set" (M672 S105:aaa:bbb) or "revert" (M672 S131:131) commands does nothing whatsoever in regards to the smart effector LED and I have to power it off/on again.

My suggestion would be to power off the machine, wait 10 seconds, and power it back on again. Then set the sensitivity and see if the smart effector responds properly. (It should blink 4 times in response.)

example
M672 S105:25:255

That's not a valid combination. If the first number is 25, the second number should be
230 (255-25 = 230)

Thank you for everyone's help i really appreciate it !
After installing a new smart effector it seems to work !

@dc42 after uploading .hex to the printer it saves my sensitivity
@garyd9 that was the last puzzle piece i completely misunderstood the instructions given

To program the sensor, send command M672 S105:aaa:bbb replacing aaa by the desired sensitivity and bbb by 255 - aaa.

Umm.. I thought the only way to update the smart effector's firmware was using special hardware.

Is that ability built into the duet firmware now? (I'd love to get that fix on my smart effector, but didn't think it would be feasible for me.)

Lihyon

@garyd9 i got no clue how the firmware works, but when i remove the hex it only flashes 2 times when i turn on the printer and when i include it i get 3 flashes because of my config. its wierd and i wont question it

(Edit: due to the forum s/w change, I lost track of a reply)

In another thread, @dc42 suggested that the firmware can only updated via special hardware. Just sticking the .hex file on the duet isn't enough:

@garyd9 Yeah I'm curious what's actually going on with the hex file being present in the sys folder would actually do.
