June 12, 2022 / Yohei Fukuma About Fraxinus Fraxinus is an attractive 3D printer for home use and space-saving workshops. Despite its compact size, it offers the high-speed operation of a CoreXY motion system, and as of 2022.06, it is available in two print sizes: ~170 mm³ and ~220 mm³ . The Fraxinus1k is conveniently upcycled from the Kingroon KP3S, utilizing the original toolhead, rails, bed, electronics, and fasteners. Similarly the Fraxinus3e is a larger model printer with CoreXY kinematics that upcycles the Ender3 V2 and cheap equivalent i3 printers alike. Note that the Fraxinus1k and Fraxinus3e lose about ~10 mm in each axes respective to their original volume (180 mm³ KP3S and 235mm³ E3V2) The cost of upcycling can be as low as 10,000 yen or $75 (provided you have the original printers with additions such as Klipper & 3D touch installed). In the process of building, you can learn various areas such as mechanics, electricity, and software. We also have a public repository for usermods that our community has developed for the Fraxinus printers. Fraxinus 1 and 3e share many common design components that may be interchangeable and updated. We expect to be possibly develop upgraded models and mods in the future, such as enclosures, or aiming to achieve higher speeds. (Fraxinus is currently being developed and published by our Discord community. If you are interested, we are looking forward to working with you to develop the design, review, share know-how, and most importantly, enjoy the company of like-minded people!

We want to create a compact yet practical printer. We referenced the VORON Zero and were inspired to create a design that is affordable using readily available and cheap printers. Use C-frame 2020 aluminum extrusions for our vertical frames. I simply thought this would be a cool building material that would differentiate our printer design. Reuse original KP3S materials as much as possible. In particular, I wanted to reuse the two MGN12 linear rails, motor, bed, board, and harnesses. Although this design merely repurposes a KP3S, I still want to make it attractive and visually appealing. Reversible design I wanted to consider the possibility that you may want to reverse or reconfigure your build back into a KP3S. It would be kind of cool to be able to put it back together. Fraxinus Design Goals/Priorities

The 1515 aluminum frame seems to have no roll-in nuts. Therefore, if a component is required to be fastened directly to the frame, it is imperative that you plan beforehand and include the appropriate nuts prior to assembly. (We painstakingly had to disassemble our original build 4 times and we advise you to work mindfully) The fragility of cheap Chinese screws is extraordinary. When reusing screws and fasteners from the KP3S/E3V2, please be careful not to over-tighten/torque the screws and work slowly. Fraxinus Assembly Notes/Warnings

First, I strongly recommend that you have an operable KP3S with Klipper and a 3D touch. Although not required, previous experience with Klipper and more importantly the KP3S itself, will help establish a baseline for your printer. We recommend that you have an environment where you can print with ABS. We recommend printing at home, at work, at school, or through acquaintances in order to have the parts ready for printing. We also recommend printing most parts in ABS because of its heat resistance and durability; PLA parts are said to melt when exposed to high temperatures, which can lead to fires, deformation, etc. We have personally experienced that PLA parts deteriorate over time and crack, so we do not recommend this. Please prepare tools as well. Many tools such as soldering irons, electric drills and screwdrivers, wrenches, tweezers, pliers, and M3 and M4 taps are required for assembly. You can perhaps borrow these tools or use this opportunity to get them. Fraxinus Pre-arrangement recommendations

01 Sourcing and printing parts

Fraxinus Sourcing Parts We will source the necessary parts based on the Bill of Materials (BOM) We recommend that you acquire/order the linear rails as soon as possible When we sourced our linear rails: MGN7H-200mm x3pcs, the delivery time was 3-4 weeks, which took the longe 2022.06.11 / Yohei Fukuma |14 Latest data can be retrieved from Google Drive (Currently open to beta users only for registrants)

Fraxinus Printing Parts Most if not all parts are to be printed in ABS. For slicer settings, we recommend an extrusion width of at least 0.45 mm, a wall count of at least 3, and an infill of at least 40%. 2022.11.7 / odaki, Yohei Fukuma |15 It is also recommended to adjust a slicer setting so that the gaps that will house nuts will have the correct size. A good value to set to compensate for expansion of said gaps is 0.1 mm. ideaMaker: "XY Size Compensation for Holes" Cura: "Hole Horizontal Expansion" Without proper adjustment/tuning, tolerances of the nut holes in the printed parts may become too small and the nuts may not fit. Methods such as heat inserting or freezing the nut may be required if you encounter issues throughout the build.

02 Machining of parts

Fraxinus 02 Parts Machining (Frame Machining Overview) 1. 1515 frames (1) Tap processing M3 tapping on both sides. At least 11 mm deep. Tap on both sides as well as on the face required for assembly. Needed to screw down the Jigu V2 for drilling. The 1515 frame, which is the X-axis, does not require a tap, but it is not necessary to determine whether a tap is needed or not It is also recommended that you tap into all 1515 frames, as this will allow you to sort out the ones with the best taps. (2) Drilling Drill the holes needed to pass a hexagonal wrench through (so-called wrench holes). A total of 10 holes will be drilled for 6 of the total 12. Note: Tapping must be completed first, as the Jigu V2 is screw-fastened to the side and used to guide the drilling. The size accuracy of the holes is not critical, but their position is. If the holes are not positioned correctly, the wrench will not b Conversely, if the size and position of the holes are accurate, assembly will be easier and more precise. 2. 2020C frame (1) Tap processing M4 tapping on both sides. At least 15 mm deep. Tap on both sides as well as on the face required for assembly. It is needed to screw the Jigu V2 for drilling. If short screws are available, the depth can be made shallower. (2) Drilling Drill the holes needed to pass a hexagonal wrench through (so-called wrench holes). Precautions are the same as for drilling 1515 frames. 3. 2040 frame (1) Tap processing Tap M4 on one side. Depth 9mm or more. only one side is sufficient as Jigu fixing is also not required. (2) Drilling Not required. 2022.11.07 / odaki |21

04 Dismantling KP3S

Fraxinus KP3S disassembly (preliminary check of printed parts) Before disassembling the KP3S, check the printed parts for excess or deficiency. Check to see if it assembles without problems in combination with the frame and screws. In particular, check in advance that Holder Idler R and Holder Idler L are output as designed. It is recommended that Holder Idler be temporarily assembled with bearings, screws, washers, and nuts and temporarily mounted on the frame. If there are problems, reprint the KP3S before disassembling it. Failure Cases and Remedies The same data was needed to print multiple pieces, but only one piece was printed and parts were insufficient. → Print additional copies I didn't realize there was an L and an R, and I printed multiple copies of one side. → Print the missing side additionally. External size was not as intended and did not fit in the frame. → Tune the print settings so that the size after cooling is about ±0.1 mm from the design value, and reprint. Or, modify the design data individually and adjust the parts to fit. The hole size was not as intended and the nut did not fit. → Tune and reprint. Or, heat the nut with a soldering iron and thermally insert it into the printed part I screwed it down and the part cracked. → Check that the print direction is correct (recommended direction) and that the infill rate is sufficient (guideline is 40% or mor Bearings and spacers did not fit in the space to be installed. → Check if the ceiling of the space is coming out as intended. If sagging, tune bridge and support settings. If necessary, replace the washer with a thin washer. It is also effective to print washers with appropriate thickness with ABS an 2023.02.11 / SummerOrange, odaki |45 Holder Idler L Holder Idler R

X EndSwitch cable I cut it in the middle and extended it by splicing. For the cable extension, I used Oyaide Electric's RSCB 0.2sq flexible silicone cord. Extruder motor cable The X motor cable was the longest, so it was replaced. 2022.07.04 / tiryoh , Yohei Fukuma |104

Power supply and cooling fan for Fraxinus RaspberryPi - The power supply for the RaspberryPi was supplied by a step-down voltage from a pair of vacant 24V terminals on the power supply unit. - For the step-down, there is a cheap step-down module on Amazon, so I adjusted the output to 5.2V output with this module and built it in. (5.2V is used because the RaspberryPi3B+ is prone to voltage drop alarms, so it is set a little higher.) https://www.amazon.co.jp/dp/B010RYGGJC - The power connection to the RaspberryPi was made directly to pins 4 (+5V) and 6 (GND) of the pin header. https://shop.lgs.jp/post-519/ - For connectors, we used Dupont connectors that we had on hand. https://www.amazon.co.jp/dp/B07DF9BJKH - Note that the screw holes on the RaspberryPi board are 2.6mm, so be careful which screws you use when mounting. - The cooling fan was supplied by a 24V fan that was left over, so it was supplied by a pair of 24V terminals on the power supply unit, which were vacant. This fan is a little noisy and vibrates a bit, perhaps due to individual differences. If you know of a better one, please let us know. https://www.amazon.co.jp/dp/B07DB7DLMM 2022.03.14 / Eitoku , Yohei Fukuma |105

Fraxinus back panel - The back panel is an acrylic panel? and very nicely processed. Remove the protective paper from both sides of the surface. - Installation of back panel - Insert nuts into the frame (it's hard if you don't put them in beforehand) - Two nuts on each of the two back vertical frames - 4 each above and below the back horizontal frame - Horizontal lower left frame: 4 pieces - The AB motor and the power switch module must be removed. - I used M3x6 cap bolts for the screws. However, in my environment, a total of three screws under the AB motor and under the power switch module had to be low head type screws or they interfered with each other. (I used the ones I had on hand.) 2022.03.14 / Eitoku , Yohei Fukuma |106

Fraxinus Bed Related - Cutting the bed - The protruding part for fixing cables on the bed needs to be cut as it interferes. - It might be easier to use a metal saw to cut it horizontally in a straight line. I cut it in an L-shape so that I could restore it, but it was quite troublesome. (I think it would be easier to use a metal saw if the bed can be firmly fixed. - Fixing of lead screw The lead screw itself was tapped with an M3 tap, so although different from CAD, we fixed it with a handheld M3x25mm screw from below instead of screw-tightening from above. - Hot bed cable route Since the cable is connected under the hotbed, it must be secured as immobile as possible or risk disconnection, so we created a simple fixing part and secured it with spacer 2020 M3.stl + M3 nuts + M3x6mm screws + ties. I used this gold saw. https://www.amazon.co.jp/dp/B0002YVI7S However, the blade is replaced by this one with a 32-mountain blade. https://www.amazon.co.jp/dp/B0026FBG14 It's pretty tough, so please hang in there! 2022.03.14 / Eitoku , Yohei Fukuma |107

Fraxinus Orange Pi Zero 2 use I think proko already did this, but I was able to get Klipper & Mainsail working on the Orange Pi Zero 2 without any problems. It took me a little while because I'm not familiar with Linux. Now I can return the RaspberryPi3B+ to the original Ender SW ^^^' Still, it is a good choice if the price is around ¥3,000 and it is so useful. I wrote a note on the installation of Mainsail Klipper on OrangePiZero2. Please let me know if there is anything wrong. We would like to correct it.

Fraxinus Printhead Lightweight I reduced the weight by integrating the L-shaped metal parts Y Moter holder and holder head-belt.stl. 40g -> 11g. 2022.03.29 / Eitoku , Yohei Fukuma |109

Fraxinus Printhead Lightweight As a result of the weight reduction, the ADXL345 measurements have improved considerably, and even with an acceleration of about 10000 mm/s2 , it seems to be OK. â I am not sure myself how to see the details, but the key point is the description of Recommended shaper written in the upper right box. If you look at the line of this value, you can see the approximate ACCEL (maximum acceleration) and SM (max_smoothing). Furthermore, if you set [input_shaper] in printer.cfg based on the value shown here, the ghost-like waves caused by resonance will be greatly reduced. https://www.klipper3d.org/Measuring_Resonances.html 2022.03.29 / Eitoku , Yohei Fukuma |110 Source : https://t.co/PUBNMqKkMz

Appendix 2 Remodelled Parts 2022.02.19 / Yohei Fukuma

Fraxinus Small diameter plastic washers We produced a small-diameter resin washer to improve the contact between the bearing and the washer. If friction loss can be reduced, speed and print quality can be improved. 2022.03.22 / Mazu-bunkai , Yohei Fukuma |112

Fraxinus 5015FAN fixing parts We are designing a fixing plate for the 5015 fan. In order to make it as lightweight as possible, the 5015 fan is fixed in place by fitting into the protrusions, eliminating the need for screws. The anti-drop ring is also designed for ease of maintenance. 😄😄😄😄 2022.04.30 / Mazu-bunkai , Yohei Fukuma |113

Fraxinus Printhead Cooling Improvement Two-way cooling Flow path division Exit Extension I remixed it for the purpose of First of all, we tried to carry on the design. 2022.04.15 / Maru. , Yohei Fukuma |114

Fraxinus Printhead Mounting Simplification I made this mounter inspired by Eitoku's design to improve belt tension adjustment. I tried to compensate for the lack of rigidity inherent in resin by using a thicker bottom surface, a bathtub structure, and integrating it with the stepping motor. The resin nut holder is slightly bent, but this does not seem to be a problem in terms of fixing. The belt tension could be easily adjusted and fixed from the front by tightening about 2 screws on the resin nut holder after the belt is threaded. 2022.05.24 / Mazu-bunkai , Yohei Fukuma |115

Fraxinus Large Diameter 120FAN Cooling Assuming a single 120 fan can cover the power supply, board, and raspi (not loaded yet). The main unit is now almost silent 🤗🤗. 2022.04.23 / Pen-hori , Yohei Fukuma |116

Fraxinus Underfloor Maintenance Made Easy I wanted to open up the floorboards to do maintenance and tinker with the boards, so I changed the design to install the boards in the opposite direction from the original design. Since removing the entire subfloor would be troublesome due to the many screws, and since we were told that the floorboards also served as frame reinforcement, we decided to open only the board section. 2022.06.01 / Proko , Yohei Fukuma |117

Fraxinus New Printhead My KP3S is 1.0, so the Fraxinus print head cannot be used as is, so I had to design an original one. The extruder has already been changed to Orbiter Extruder V1.5, so I will use V6 for the hot end, 5015 blower fan for filament cooling, and 4010 fan for heat sink cooling. 2022.06.05 / Proko , Yohei Fukuma |118

June 7, 2022 / Yohei Fukuma Fraxinus 1kc I am pleased to report that I have attached a c2 enclosure to Fraxinus (first generation). It seems to cover mainly large acrylic cost about 2500 yen without any problem. 30min printing seems to go to less than 50 degrees inside the chamber temperature. It seemed to be fine without any cover on the back corner.

Due to the characteristics of the KP3S substrate, even 3D touches that can be used with other 3D printers may not work, and I will list the results of my trial last summer. From right to left: Aibecy, Iycorish, Deanyoyo, F Fityle, SM SunniMix, and the roughly transparent cavity one did not work KP3S.
