    I finally had some more time to work on this. Today I finally had a bit of a test with an actual game (using Forza Horizon 4 and black box motion for cars). This seems to work-ish, but during some more violent moves I noticed that sometimes some of the actuators actually hit the end (at the bottom). Which means that it went beyond the endstops - by more than the length of the slider piece in fact. If I am moving the rig manually (as shown in the above video) the thing always stays in the normal range - far beyond even hitting the endstops. Any ideas on why this would be happening?

    Hello everyone,
    I would like to start the project and I am very impressed by what you have already achieved!
    Does anyone happen to have the design as a STEP file?
    That would help me a lot with the mechanical production...
    Many thanks and best regards from Hanau, Jörn.

    Instead of BLDC8015A i am using BLD300 driver Please guide me what changes need to be made in the code ?

    Last year I have build my first 2dof platform with brushed motors, wormgear using mega2560 with smc3. I was amazed, it worked and experience flying dcs in vr is just insane.
    Now I would like to build 3dof. I have bought 57BLF03 24v with BLDC-8015A driver and smc3 board. Before I build rig I want to test motor but I came to a small issue when I was trying to upload your code from page 1 to smc3. There is a problem with lines 185 and 186 compiling it. I goggled it and found that with new upgrade some APIs were removed and replaced with others.
    Removed APIs
    • ledcSetup
    • ledcAttachPin

    • I don’t know what to do and can’t proceed. Can you please help me with this. Thank you.

    Smc3? This project uses a diy board with esp32

    Oh I sorry for my mistake. Smc3 with mega2560 I used last year for my 2dof.
    Now I would like to build my new rig based on ESP32 board with your code. I Can’t upload your code because some APIs were removed/replaced with others. 2 lines having issue. Line 185 and 186.
    Please help.
    Thank you

    i ordered another board and I tried couple more times to compile your esp32 code but i had no luck. Its still the same problem, line 185 and 186. Like i said before i google it and found in Arduino forum that some APIs were removed or changed. UGHH.
    So after failure with above i bought Arduino UNO (came today) and for last couple hours Im trying to figure it out.
    Code compiled/uploaded with no issues, Great. I wired 57BLF03 motor to BLDC-8015A driver as per your diagram from page 1. Got 2 microswitches, 10 turn potentiometer.
    This is my driver connection:
    Blue - W, Green - V, Yellow - U
    Red - Ref+, Yellow - HU, Green - HV, Blue - HW, Black - Ref-
    F/R to ard to 2, AVI to ard 3, Grd to ard grd which is also connected to power supply ground.
    2 microswitches and pot also wired and checked.
    When i turn on power, motor spins all the time without uno connected and even with uno connected it only spins. I tried to move potentiometer and press limit switches and nothing, just keeps spinning. BTW both small switches on the driver are in position ON. When i push switch nr 2 to off motor stops but still pot and switches not doing anything.
    I already started building 3dof platform and i was so excited about it.
    Please, any i will appreciate any help.

    As @pmvcda ha alredy pointed out:
    If you post specific information regarding the esp32 difficulties then perhaps those following this thread may be able to offer some insight and ideas.

    But with respect to an Arduino, and some seemingly random related external forum information which may or may not be relevant to motion simulation, you need to start an independent thread specifically about that approach, linking in all relevant information.

    I wanted to give update on the issue I had trying to upload esp32 code. I read that in latest update to esp32 library by espressif (3.0.4) some API were removed or changed and that probably created issue with uploading this years old code.
    So I completely uninstalled Arduino and deleted all the files. Then I installed arduino again but I chose to install previous version of esp32 by espressif library and WOW it worked. Compile and upload was successful.
    Now I’m into wiring and testing 1 motor first. Will keep you posted.
