    Currently I have made a 2 dof platform, but my desire to make a 6dof calls me :)

    Seeing this project draws my attention.

    I have some doubts about the actuators.

    The profiles used are not designed to withstand the slippage of PET-G plastic. Is it cirerto?

    Does PET-G plastic support the friction of friction by the profiles?

    I attach a photo

    The printed parts. Are they 100% solid?

    Thanks in advance and congratulations on the project.

    Hi, sorry for the delay answering.

    Yes, they are solid PETG, and they slide well in the AL profiles.
    But make some printing tests if you want to follow my design.
    I had no problems with friction util now.

    I have a very important question:
    I would like to buy BLDC-8015A drivers, but I read from the official characteristics that the PWM duty cycle is 1Khz.

    I have a 15Khz PWM signal, can I use it anyway?

    hi @pmvcda!
    i'm amazed by your project and your software.
    I think i'll finally build my own simulator !
    But i have a question: with a similar system like the one in your project, in fact esp32 + BLDC motor, but with a Nema 34 440w BLDC motor ( 86BLF04 ) and a 8015-a driver, would it be possible to create a direct drive wheel?

    Hello FlyPT,

    We started building a 6DOF with your hardware. We've build 3 actuators and wired them on a testboard.
    They all calibrate correctly: Going to max pos (switch) back to min pos (switch) and stay there.

    When i connect the old FlyPT 6DOF software or the Mover software or SimTools whatever we setup the only thing the actuators are doing is going from min to max to min to max etc.... they are bounching away.

    Even when we look at the serial debug and the numbers are solid (not changing) still everything bounches. We are a bit clueless what is happening here. Do you recognise this and maybe you can help us or give us a hint how to solve this?

    Hi, sorry for the delay.

    I will look at this tomorrow.
    But for the latest ESP32 code you need to use the latest Mover version.

    There was an error on the schematics, but I think it's already corrected in the posts. Need to see it, I don't remember now.

    Depends on the motor ccontroller you have.
    What is done here, is for the BLDC8015A
