If I understand you correctly, It is a combination of the sensor and the geometry. If I change one of those the problem is solved.
The geometry is difficult to adjust.
That leaves us to work on the sensor.

The inductive sensor is a contactless sensor, a contact sensor is better. If I don't swap the sensor how often do I have to measure the probe trigger height? I did read the instructions, but it isn't looking easy to me. And the next time I want to calibrate, can I use a full auto calibration or not? And the IR sensor is no better replacement.

If I use the piezo sensor I have to modify the effector. But calibration would be much easier.

I did see the Smart Effector, but I don't like the idea of changing to that because of the rod swap - carriage swap. My printer is a good mechanical printer, it's the calibration and the board that isn't satisfying me.

I did setup octopi but I have to reset the usb port now and then on the Rumba board. But right now that isn't working.

It not so much a contact sensor vs. a non-contact sensor, it's a sensor whose position coincides with the nozzle vs. a sensor that is offset to one side. The more the offset, the more sensitive it is to effector tilt. That's why nozzle-contact sensors are good for deltas, and also why I designed the mini IR sensor to be small enough to fit below the heatsink of the R3Dv6 hot end so that it can be close to the nozzle (i.e a small offset).

Hello

Everything recieved. I looked at the wiki, but that's more for a "home build" 3d printer. And I lost track on the things I have to do (configuration).
I don't know the parameters I need or the value. How can I determine all those values?

Can you point me to the pages / help me with the transition from a Rumba board not functional commercial 3D printer to a working duet3d "frankenstein" printer.

Thanks

To transition the wiring, start with https://duet3d.com/wiki/Wiring_and_hardware_differences_from_RAMPS_etc. (I think connections on RUMBA are quite similar to RAMPS). Then look at the Hardware and Wiring section of the wiki main page.

Regarding configuration, you can use https://configurator.reprapfirmware.org/ to generate the config.g and homing files for you, and look at https://duet3d.com/wiki/Configuring_RepRapFirmware_for_a_Delta_printer to get a better understanding of what the commands in those files do.

Thanks for the links, but I can't use https://configurator.reprapfirmware.org/
My dimensions are too big
These are my dimensions Printerdimensions :42 cm x 53 cm x 101 cm, print area Ø 30 cm x 42 cm

If the problem is that you can't enter 150mm as the bed radius, enter the delta radius and diagonal rod length first, at least approximately.

RKS7204

ok, so I take the max allowed values if my values are too big. Afterwards I have to adjust the generated files.
Can you give me a list of the files that needs adjustment and the commands inside them that needs adjustment?
How can I determine the steps/mm for the extruder and x/y/z motor?

dc42

No, your values are not too big, however you need to enter your diagonal rod length first because the delta radius and bed radius will be limited to plausible values based on the diagonal rod length.

RKS7204

ok, sorry I didn't understood it at once.

Maybe swapping the left and right column on the webpage is advised?

RKS7204

Probably a dumb question.

Is there a possibility to have 2 options for autocalibration? I have doors on my printer and when the doors are closed I have a printable diameter of 20 cm. When the doors are opened I have a printable diameter of 30 cm.

Is it easy to swap between 2 different sizes for autocalibration?

Everything arrived I'll be changing everything on Sunday (I hope).

dc42

Yes, just create a copy of bed.g with the dimensions changed, put it in your /macros folder, and run it to auto calibrate with those dimensions.

Next question, I can't find an answer for.

I have the following on my printer
-3 ledstrips connected to 1 connector (always on fans)
-1 fan at the board connected to always on fans
-1 fan for the hotend connected to fan0
-3 fans for cooling the print connected to 1 connector connected to fan1

I'd like to have the following
Leds always on, Board Fan always on, hotend fan on when printing, print fans controlled by slicer off when printer is powered on

How do I do this?

Thanks

I suggest you swap the Fan0 and Fan1 connectors. Fan0 defaults to being the slicer-controlled print cooling fan, and Fan1 defaults to being a thermostatic hot end fan.

I powered up my ethernet board.

First thing, no network connection.
Because the Ip adres is hard coded to 192.168.1.14, and my subnet is 47.
So I had to change the IP adres to 192.16..47.80

I tried to calibrate.
My Z-probe sensor isn't installed yet.
I tried the manual calibration(Pressed Delta Calibration on the Machine Control), but that gives me only the possibility to change the X value, not the Z value.
Then I tried this http://www.escher3d.com/pages/wizards/wizarddelta.php and used the G-console. After calibrating things are even worse.

Is there a way to do manual calibration?

Which versions of the main firmware and Duet Web Control are you using? You need to use more recent main firmware or an older version of Duet Web Control.

RKS7204

I'm using
Firmware Electronics: Duet Ethernet 1.0
Firmware Version: 1.19 (2017-08-14)
Web Interface Version: 1.19

Hello,

Great board, first print came out and was excellent.
No elephant feet, and the only noise is from the fans.
