The box was pretty picky about connecting to printers and there were many other problems. In addition, the box integrates with a Thingiverse-like library and does cloud slicing, which is attractive when you have a very small computer connected to your printer. A Raspberry Pi with a similar case would be at least twice that price. You can buy the Creality box for about $20. You might wonder why you’d want this system when Octoprint exists? Mainly, the value proposition is the price. noticed that Creality now has an inexpensive WiFi interface that promises to replace Octoprint and decided to give it a quick review. Read 55664.530720: 'N155737 M105*21\nN155738 G1 X110.530 Y115.307 E0.A very common hack to a 3D printer is to connect a Raspberry Pi to your printer and then load Octoprint or a similar program and send your files to the printer via the network. Few times printing failed because Klipper doesn't support g-code line numbering and Repetier-Server shuffle the lines. And most desktop distros offer the header package. You will see "klippy is not ready" messages on each m105 request in the console log with 0c temp reporting. ![]() You can however still test it without any MCU connected in a VM or Linux desktop host (used lubuntu 17.10), thats how I discovered that it works first. Installing raspberrypi-kernel-headers works for tty0tty, but doing quick search, it seems new rpi debian images (w/ kernel 4.4 ) repos no longer offer that so back to crosscompiling. Not sure what I did there, but # should work and is I think already included in latest version. Next release will also detect non standard gcode and send it also 1:1 but maybe with line number and checksum. Das added this for smoothieware but should work here as well. That way you can use the special commands as well. You can force server to send commands 1:1 by pretending a # like So it really depends on just adding support for pseudoterminals. But I'm happy it works for you and it is good to know communication works fast and stable with klippy. No matching headers for kernel so it refuses to load the module. I would like to combine two great products May you suggest me what can I do to fix it. I tried manually change the Device / Port in connection tab to /tmp/printer but the Repetier Server didn't connect it. Needs to talk directly with the Klipper host software via Software talks directly with the micro-controller - Repetier Server ![]() ![]() Server software to connect to /tmp/printer. "In order to replace OctoPrint, you'll need to convince the Repetier I asked the developer of Klipper to integrate it with Repetier and he answered me next: And OctoPrint "talks" to the firmware through it. In OctoPrint I added specific serial port in "Additional serial ports" section - named /tmp/printer. I succesfully run it with OctoPrint but Repetier Server has much much better Touch UI and many other nice features. ![]() The same host computer can be used to run both Klipper and OctoPrint." The micro-controller then uncompresses the given schedule and executes it at the specified times. The host does all the work of determining how and when to move each stepper motor, it compresses that information, and sends it to the micro-controller. "Klipper is a new experimental firmware! It is designed to run on both a micro-controller and a low cost host computer such as a Raspberry Pi. Is it possible to connect the Repetier Server to a Klipper firmware?
