**My Experience with the Delta 3D Printer Kit: A Comprehensive Guide**
As I embarked on building my Delta 3D printer kit, I was excited to see how it would turn out. The process began with gathering all the necessary parts and plugging them in, which included using a USB stick containing the assembly manual in my laptop. The build process was available as a commented picture slideshow or as a definitive video series, which I preferred. With its help, I was able to complete the build within 4-5 hours, a relatively fast pace compared to my previous 3D printer kit builds.
The mechanical instructions were clear and easy to understand, making it simple to get the aluminum tubes into place, mount the motors, or attach the extruder assembly to the Zed axis. Precision measuring was only necessary once, ensuring that the top plate had an even distance to the print pad. The wiring instructions were also straightforward, at least until a certain point, as it wasn't mentioned how to hook up the fan of the extruder. Thankfully, though, the electronic system was built around an Arduino Mega with RAM Shields, which is open-source, making it easy to find wiring diagrams or necessary firmware changes to customize my Delta printer.
As I finished the assembly by tidying up the wiring, I noticed two significant improvements. Firstly, due to the three Z-axis, the electronics and filament could stick very well on top of the printer, making it a reliable machine. In comparison to my old printer, the measurements in the X and Y axes were around 10 cm smaller. Secondly, due to the hidden wiring, the printer itself looked more pleasant to the eye, without the chaos of wires on the side that might even get in the way of working.
After uploading the given firmware to the Arduino, I started the RapidHor software and configured the printer and slicer settings according to the manufacturer's recommendations. The almost last remaining step before my first test print was the so-called M666 calibration, which is necessary because the height of all the end switches is never completely the same. By manually adding an offset for each individual axis with the M666 command, I ensured that the distance between the nozzle and the bed would be even for all X and Y positions at the end.
Next was the auto-level feature, which gets activated by placing the G29 command in the start gcode section. For this, the inductive sensor needs to be positioned 1 mm away from the end of the nozzle. It wasn't easy to find the sweet spots during the first try, but with a couple of adjustments, it should work out just fine.
During my first test prints, I noticed that the quality was already better than everything I printed with my old 3D printer. However, a small problem occurred with larger prints - the so-called warping, which lifts off the edges. This can be solved with different approaches, and I simply went with a heated bed.
A problem arose when trying to connect the 12V wiring for this particular bed, as it drew easily above 8 amps, which my power supply couldn't offer. Luckily, though, the 24V wiring only drew around 2.1 amps at 12 volts and also reached a temperature of almost 50°C, good enough for PLA.
To solve this issue, I marked the outline of my old bed's sensor out on my new one in this outline, drilled necessary holes, soldered out wires to the heated beds, secured this wire and the temperature sensor with Kevlar tape, screwed the bed in place, used zip ties to secure the wires to a tube, and finally connected them to the RAM Shields by adjusting the firmware to turn on the necessary digital pin and uploading it once again.
I was finally capable of using the heated beds to print on, and I have to say that all the test prints I did after this modification came out flawlessly. In conclusion, I can recommend this kit to everyone who likes to tinker and wants to have a decent printer with a success rate of around one out of two prints.
