Thank you for sharing an impressive video of Octopus with us. More Voron users can have our Octopus install in their next build. Regarding HV CAPS, we love hearing your ideas! We'll definitely pass your desire to our teams. We will keep delivering quality products to you! :)

@DetlevRackow 3 года назад

Hello BTT folks, some clarification on the probe issues would be most helpful. This is confusing, as the new port was meant to be better suited to this kind of probes.

@SergeiSugaroverdoseShuykov 3 года назад

it's a good idea to at least bore holes through board on caps connectors so enthusiasts can replace caps themselves placing them on back side of board: actually it's impossible to fit SMD caps with bigger voltage on face side of board while holes can be bored in newer revision w/o any issues(ofc if there's no traces under them)

@Kalvinjj 3 года назад

@@SergeiSugaroverdoseShuykov I think having through hole ones sideways like some Arduino CNC shields do could make that possible, but that would of course make them stick out further to either way and thus the jumpers go somewhere else, either jumps or caps have to move.

@rayramirez 3 года назад

One small observation. The header that you called out above the fan ports is an SPI header. For the Raspberry Pi connection, both serial and power come from the "UART" header directly to the right of "MOTOR7". There are 2x5v, 4xGND, and TX/RX in a non-pi standard orientation (unlike the spider header layout that matches the Pi's). If you are going to use this header, be mindful of the pin layout in your jumper as to not damage your Pi or your Octopus. If you plan on using UART instead of USB, you will need to setup the firmware to use "Communication interface (Serial (on USART2 PD6/PD5))".

@NorthAlabamaPC 3 года назад

Great review and information; one thing the wrong connector pointed to for Raspberry Pi, the correct connector is next to the I2C connector.

The spider actually supports 6 Fans, only 3 are "dedicated" fan headers, the other 3 are multiuse headers that can be fans or LEDS for example. And of course any unused hotend heater pins can be used for fans too.

@ZachSchimke 3 года назад

Would actually want larger than 50V caps for 48V motor power. Those bulk caps tend to loose a significant amount of capacitance (up to 50% in some cases) due to DC bias. I would argue that the 35V caps used are correctly sized for 24V.

@TheWhatnever 3 года назад

You are thinking of MLCCs. Aluminium electrolytic caps are almost not affected by dc bias.

@ZachSchimke 3 года назад

Yeah, I was thinking MLCCs. I rarely (if ever) use axial/radial caps in my designs. Still a good idea to have a cap rating higher than 5% of the input voltage since most power supplies' ratings will be about that. Better safe than sorry.

Really enjoyed the video and this will help me with getting my 2.4 unit operational. I would like to share a caution. When handling circuit boards with ESD (electrostatic discharge) sensitive components, please consider using an ESD wrist strap and mat that is connected to an earth ground. Watching you touch pins and connectors made me cringe as low voltage discharges, which you can't see or feel, can weaken the internal structures of IC's and other devices. This can shorten the lifetimes of those parts and cause failure a few months down the road. Anyway, just passing along a tip to help keep printers up and running.

They pack them in so tight that they're bumping edges by default.
