Showroom My 6DOF with DIY Actuators

Thanks for asking, I got my replacement Sabertooths 2x60 back and installed and actually everything is ok. Only I have a new little problem. A stöhr noise.A video recording is still under construction

actually I have to sleep long ago

where do you monitor noise? @Vitalius

im thinking of shielding the hall sensors using USB wire (just discovered today testing a the hall sensor cause i was checking gear play and mistakenly reached the 10 turn limit for gear misalignment..STUPID ME ALMOST BROKE 30$ hall sensor)... USB cable has shielded 4 wires!!!

and using coax cable for the link between arduino and sabertooth...

Hello. thanks for the feedback!
So the noise comes from engine 2 in the photo with the arrow.
Two motors run with the hall sensors marked H in the photo.

Here is a video of Tonight or this morning.

Then I installed "Folding ferrite filter sheath current ferritic core suppression". Link
Marked in the photo with green dots.
And suddenly the 10-12K noise is gone!

I have to test a lot! Wait, I hope that is not a random. By the way, I only use a shielded cable everywhere. He is not grounded!

All I have ever used is Cat5 cable for my pots never ever had any issue with noise

I have to absolutely look at your electrical installation or your RIG. Maybe I did something wrong with my installation. Maybe you have done something better ;-), or have better engines .
Did you ground your shield?

Mines a right botched job it's not grounded and I use the same cable for the limit switches too.

And how is it with you? What's new with you?

nothing much. still building. workin on the pulley and hall sensor assembly.
im trying to keep my spirits up.
your posts keep me going.
its a long road, especially when using hand tools.

Last change to my Actuators.
I had to realize that my limit switches break out of each other.
I bought new ones that are bit more robust and had to match the holders for new switches.

Two out of four 360 degree Hall sensors have been installed for more than a month and run flawlessly.
I still have to block it. A lot of work!

And I will replace all sliders that are not so stable against new sliders printed with 100% feel

keep going brotha! i am also back at building my pot assemblies!

but my opinion is that i dont think having the tension on the pot is a good idea..

The toothed belt wheel is immersed in the housing so that the tension of the toothed belt wheel is absorbed by the housing. This creates a bad ball bearing with a lot of friction. I will show the 3d drawing later. The normal cheap potis have been held for almost 6 months.

The Pulleyslides or lies on the housing.

I still have so much work!
The here with gas spring is also in planning.
I am not sure yet how much pushing force should I take. And if that works

im hoping to finish my actuators by mid month if not but the end of month. i have tons to do as well...im not where looking at gas struts yet..
