I’ve been trying to get in contact with support only to get a response from insta it’s a joke honestly about my order that has had no updates in 18 days just got the Ali express rep to say do you want a refund they are actually a joke I’ve been trying to tell them there something wrong with my order for days and now they use their brains to offer a refund it’s a joke of a company if they can’t get there customer service in a good place

I reached the customer several days ago, explaining clearly that my brand new octopus max ez bough in January is no longer working. I provided pictures, videos.

3.3v is no longer working on the board and prior the failure fan stopped working as well.

I feel like I'm talking to a bot as they ask me to test the fans over and over. I can't connect my board to mainsail, board is no longer recognized by the pi (lsusb command shows only the eddy USB).

I'm about to give up and throw my board to the trash and never go back to btt

I have the Manta M8P V2 board installed on my printer and I want to add some RGB lighting to it. The plan is to use a standard 4-pin RGB LED strip (R, G, B, GND) and control each color channel separately with MOSFETs so I can mix colors properly instead of just having a single fixed color.

The problem I’m running into is that I only have two HE ports left on the board, and I’m not sure what the best option is to get a proper 3.3V–5V control signal for the MOSFETs. I’ve been looking at the fan ports since they are PWM capable, and also at the 40-pin GPIO header, but I don’t really understand how practical or easy it is to use the GPIO pins in Klipper.

Right now I’m basically trying to figure out if I can just use the fan outputs directly for controlling the MOSFETs, or if the GPIO pins would be a better and cleaner solution. I’m also wondering if there is maybe a simpler approach I’m missing that doesn’t require buying extra controllers or additional hardware, since I’d prefer to keep this as cheap and straightforward as possible.
If anyone has experience with the Manta M8P and RGB LED setups using MOSFETs in Klipper, I would really appreciate some advice or a short example of how you handled it.

Hello,

I am having trouble getting a dual part cooling setup to work on the EBB36 Gen2 toolhead board. The common solution that i have seen is the use of the multi_pin function but that seems to only work for every other type of fan in the klipper config and not for the part cooling fan [fan]

I had massive issues with the BIQU micro probe not working deploying and stowing reliabilly. Even got a second one but had the same issue.

I left a review stating as such and they deleted it from the website. They make good stuff in general but this is poor form.

I have a btt mini 12864 v2.0 that I’m trying to use on the btt octopus v1.1 (not the pro). I can get the board and screen to boot and everything but I can’t see what the screen says without shining a light on it. For some reason I don’t have rgb backlight control even tho rgb is defined, and using the lighting menus through the screen don’t do anything. as far as I can tell the rgb_din on the screen lines up with PE13 on the exp1 port on the board so that has been defined as the rgb path for all colors related to the screen. As far as know this screen is not neopixel (not shown as such on btt’s website) but I would love to be mistaken. Any help or advice would be great.

We truly appreciate your patience, support, and understanding during this time. Thanks for sticking with us — and we’ll keep everyone updated as things progress.

I just ordered it yesterday off of amazon and got it today and installed it. tried flashing to klipper firmware and the usb wont show up on my klipper host for some reason. doesnt look damaged or anything. any ideas would be helpful. I did message bigtreetech on amazon to see what can be done.

I've had this unit for 3 months now, it has yet to provide a decent result

Finding stretched nearly torn belts on the filament feed shaft, stripped grub screws on the filament gears and pinched wired in the case feeding the chamber heater. This unit is not worth your money. Inconsistent spool winding sometimes it works sometimes you end up with a ton of filament inside the machine not nearly spooled back on the roll.

Latest failure, to feed. The idlers tight the cam rotated the filament is snug in the tube but it does not feed.

This is the worst product btt has released it needed more time to figure out how to actually work.

Initial setup was impossible had to switch to happy hare as the btt automatic installer wouldn't complete with no clue as to why.

Just letting everyone know, as im really fed up with BTT customer support. They WILL NOT HONOR THE WARRANTY. I have a Manta E3EZ board that had suddenly stopped working (I personally think it is the UART multiplexer chip).

I first contacted them in January, and now they are telling me I'm out of warranty, just because they think I'm an idiot and its a config problem or something. It's not. I've bought a second board, and everything works on it. All the wiring and configs is the same. DO NOT BUY BTT! I can paste the whole email chain here if ppl want to see it.
