    Hey! Haven't spoken in a while, printer kept failing on the first layer all the time and left it for a while, just came back to fix it and suddenly it's all working almost perfectly without me even touching it

    How's everything going?

    Can I use that wildwood cylinder on the brake version 5.2 cylinder holder ??

    What difference in touch is there from one cylinder to the other?

    Do you think I can gain brake pedal travel if I put a master cylinder with a larger diameter and a longer cylinder rod?

    https://www.gt2i.es/bomba-de-freno-...191mm-075-longitud-160mm-366176800118785.html

    The latter sets these specifications 19.1MM 0.75 LENGTH 160MM I see that it is longer, do you think I can gain more travel with one of these?

    Loving the look of that gearbox! I've been wanting a gearbox for a while and that looks amazing! How have you made it so it doesn't work properly without using the clutch pedal? How does it feel? Also can you use it without the clutch pedal, like a semi automatic?

    I just created a new thread for it : https://www.xsimulator.net/community/threads/wip-srt-gearbox-with-hydraulic-clutch.15033/
    Yeah I will add a system to disengage the clutch system so it can be a semi-automatic.

    No, you need the v5.3.
    No difference in touch.
    For more travel, try a smaller piston. The black MC is 0.7.

    The 0.7 serious the diameter, the thickness of the piston? Do you mean that with one less, for example, 0.6 can have more travel?

    0,7 is the piston diameter. the smaller the piston, the longer the travel.

    Going to build these, still waiting for some parts and figuring out why my printer seems to print y axis larger/longer then it should, just happened all of a sudden :(.

    @7HUND3R very nice !!!
    If you are looking for the electronic interface, I am working on this adapter, it is very handy to use because there is no code to flash, and there is a small software to calibrate the pedals !

    But how do you connect the USB to the pedals?

    This picture should help you :

    You plug the USB to the computer, and the VGA to your pedals.

    Please note that the Willwood and OBP rod aren't M8, they are 5/16-24 UNF threads, so they need this 3D printed rod.

    but for that I have to put another female VGA connector to the pedals, right?

    To connect my pedals to the leobodnar cable, can I connect the pedals to a male vga connector following this scheme?

    1) LOGITECH (G27, G29, G920…)
    You can connect the SRT pedal set to a G27 or G29 steering wheel. To do so, use a VGA male connector with the following pins:

    1 – VCC (+5v)

    2 – Accélérateur

    3 – Frein

    4 – Embrayage

    5 –

    6 – Masse (0v)

    7 –

    8 –

    9 – Masse (0v)

    Anyway I prefer to connect the pedals to the base of the g27 that I have. Right now I'm using the pedals on the g27. I want to remove these and put yours but using the g27 base coenctor where the g27 pedals are connected.

    I am doing the clutch pedal to itself.

    This is the best thing to do if you have a G27.

    Regarding the clutch, you can build the brake pedal, and plug it to the slave cylinder that is in your picture.

    A few pictures of how I am looking. I have to print the brake pedal, which will be the same as the clutch pedal. The accelerator is on the waiting list too.
