Which version did I get? How do I check?

in Support

I just got my ordered 3dC. I ordered the V4 the first day the website was updated. However it looks like the V4 firmware hasn't been released yet based on some of the posts on the forum. Is there an easy way to find out what version firmware I have (if it shipped with the V4 or V3)? I'd rather wait to put it on my Creality K1 until I have the V4 for the easier setup. Also is there somewhere that has the previous instructions to update firmware (V1 to V2, V2 to V3) since the hardware is apparently the same I'd like to familiarize myself with them for if I do need to update the firmware(or for when I have to update it down the line.)

I believe the upgrade instructions post Bill is referring to is this one: https://www.3dchameleon.com/forum/getting-started/mk3-firmware-upgrade-instructions

I thought in one of the videos I watched Bill said the new Mk4 hardware includes a USB-C port specifically to allow for easier firmware updates (aka not requiring a USBTiny adapter anymore), but I can't find that specific video now. I've ordered my own 3dC but haven't received it yet, when it arrives hopefully I can give you more information.

Replying to

You might be right. I attempted to locate a post I had read a few days ago, but I didn't see it. I did find one where Bill said the following though: "Beyond the add-ons, to support additional I/O, you'll need 3 additional components, an I2C bus, a I2C I/O Port expansion and a 5v to 3.3v converter." ... so apparently the I2C expansion board thing I was thinking about is only for I/O, which would pretty much only be the 4-way filament runout sensor thing. He also said "Mk2 and Mk3 users will need to add two connectors to the existing holes on their board" ... so I might have accidentally combined two different things in my head somewhere between watching videos/reading posts and then attempting to answer questions a few days later.
