Whoever sent cookies via mail didn’t think this through. That’s why cookies are usually wrapped in a plastic form to hold them in place and separated from each other or in a tight stack.

I really want a X1-C. A colleague has one and loves it. But I can’t deal with closed source and mandatory network.

First change. Install Klipper and run it of a Raspberry Pi.

Everyone recommend HomeAssistant and it’s great. An alternative that’s easier to implement if you’re using Apple HomeKit (on HomePod or Apple TV) is HomeBridge. It’s super easy to setup and becomes a bridge to make anything compatible HomeKit.

In cura switch to the preview mode to see the paths your printers will lay plastic at. It will tell you a better idea of what your final product will look like.

It’s at the top of a mountain.

That was the best pun. It’s all downhill from here

Every time I see those letters I think about the fact that I spent years not realizing that the movie Welcome to GATACA is a gene sequence.

NSFW!

You can but it doesn’t mean you should. The way Octoprint manages interacting with the printer is it spoon feeds g-code lines one by one. So it can stop sending them to pause a print, change the values to change Z height for instance etc… however, Klipper is usually able to print faster than Octoprint an send gcode via serial. The crutch is to use VirtualSD mode in Klipper but then Octoprint has very limited interaction with the gcode other than start stop, no gcode modification possible. Enters Moonraker. Moonraker is an API that allows to interface with Klipper in a standardized way to send complex commands to the printer. Mainsail UI is using it, so is Fluidd, KlipperScreen, Telegram bot etc…. The benefit is that Moonraker commands Klipper to do the changes natively instead of adding a layer to the chain. So yeah you can use it, but there is no real incentive to do so now that Moonraker is here. 5 years ago Octoprint was the only way to control Klipper and it was just painful, but we had no alternative.

You could use multi material with color change on the hour. You don’t even need to flush the nozzle you could have the color gradually change throughout the layer, or print a handful of perimeters only between each hour.
You could have the first sector to be filled with a hole in the shape of the hour number. Then on the hour change print a couple of top layers covering the hole and print the next layer with the next number as a hole. It’s a really cool idea, as long as you don’t use a heated bed and manage your nozzle heating properly to keep your electric bill manageable. Also you definitely want low print speed and some TMC drivers hehe.

You’re welcome. There is a lot more than that even. When you start digging through, Klipper allows you so much control. You can even have your printer run shell commands (deactivated by default because it so powerful, it can be dangerous if you don’t know what you’re doing)

You can control RGB LEDs and more. You can also connect many arduino isntesad of just one

So both Klipper and Marlin+Octoprint use a Pi and an arduino (in simplified versions, the SBC and the MCU can be any boards but I’ll use those brand names to make it easy).

Marlin uses the Pi to display the web interface, then sends the gcode to the arduino. Then the arduino does the math to convert the gcode to motor commands. Gcode.

Klipper uses the pi to display the web interface, but it also takes the gcode and converts it to motor commands in the pi and only sends those simplified motor commands to the arduino.

So with Klipper the arduino doesn’t need to convert gcode which is a pretty intense computation. Also, gcode is actually pretty heavy to send vu serial over usb in Marlin and often the printer can print faster than the gcode can be sent. Which results in hang ups in the print, the printer pauses, especially in a print with a lot of curves and printing fast. Klipper can use the full power of the pi to make intricate motor commands, fine tuning acceleration and all to avoid vibrations (input shaper, it even uses an accelerometer sensor to refuse vibrations making cleaner prints and quieter printing)

Other benefits of Klipper, settings don’t need to be flashed to the arduino, they are saved in a text file on the pi. Changing Config is a simple text edit, then reboot to apply the changes. You can edit the settings right in the web interface.

One of the down sides of Klipper was that you had more functions in Octoprint with plugins, that’s not true anymore. You have many plugins compatible with Klipper with Timelapse exclude area, remote access, Obico (the spaghetti detective), and so on.

The web interface is much lighter and responsive than the bulky Octoprint. Octoprint was an afterthought while Mainsail was purpose designed for Klipper.

I used to run Marlin and Octo and hated the experience. Since I tried Klipper I can’t go back.

I’d be curious to see numbers Vs Fusion360.
