@dc42 thanks, that was the thing I was looking for

Hello everyone,

I think I have the same wish.

I would like to connect three 4 pin pwm fans to fan output 4.

It is an always running fan for my water cooling system.

That means it has to run when the nozzle is around 45C. This is already working. But the fans are too loud and too strong. I would therefore like to reduce the fan speed to 30%.

The fans are connected via a 3-way splitter and this is important for me to have some kind of redundancy if one is faling.

How can I achieve this? @dc42

Hello together,

I do not know why but the plugin for input shaping is not visible on the left side in dwc. I have activated it. for e.g. hight map it's working.

Any suggestiion?

Thank you.

Have this problem also with Software bundle 3.4.0 beta 3.

Any Ideas?

Hello together,

when I use 3.4.0beta2 my delta printer prints crooked in y-direction along the z-progress.

I do not have this problem with 3.3 stable.

Any suggestion for this problem?

here is my config:
c4d1f6bb-1c8a-49f5-b2a5-d04a6a8038fa-config.g

@mfs12
thanks alot for your work.

Unfortunatelly I'm getting this message:

how can I solve this?

Best Regards

@dc42 just want to let you know that I had good results by eleminating 30Hz. By using M593 P1 F30.

Is it possible to eleminate more than one frequenzy? E.g. M593 P1 F30 F60?

Best Regards.

@dc42 thank you very much for all this information.

I have some questions:

In the M956 command, to wich value should I set the F parameter. To the speed of the outer wall in the slicer settings?

Unfortunately I do not see any improvement by using M593.

How should I set this up?

Is it possible to eleminate more than one frequency?

Does it make sense to mount the acceleration sensor to one axis carrier?

Best Regards,
Cai

@dc42 sorry, not my day

I've done again in all directions because of some congfig changes I've made regarding acceleration and yerk. So here are the latest data:

x-direction:

G28
G1 Z100 F20000
G1 X-50 G4 S2 M956 P0 S2000 A0 G4 P10 G1 X50 F18000

y-direction:

G28
G1 Z100 F20000
G1 Y-50 G4 S2 M956 P0 S2000 A0 G4 P10 G1 Y50 F18000

xy-direction:

x_raw.csv
y_raw.csv
xy_raw.csv

Hope that now it's more usefull.

For me it looks like there is resonance at 67 Hz

BTW I'm using Adafruit LIS3DH with this config:

M955 P0 C"spi.cs3+spi.cs4" S4800 Q400 R10 I20

Thank you very much for your support,

Berst Regards,

@zapta Yes I guess youn are right. What do you mean with kind of configuration?

@dc42 How can I make the accelerometer trace visible, not shure what you mean.

Here are the results:

Y Move:

G28
G1 Z100 F20000
G1 Y-50 G4 S2 M956 P0 S1000 A0 G4 P10 G1 Y50 F20000

XY Move:

G28
G1 Z100 F20000
G1 X- 50 Y-50 G4 S2 M956 P0 S1000 A0 G4 P10 G1 X50 Y50 F20000

So I guess you are right with 28Hz.

Best Regards
