Kywoo Tycoon EVA 3.0 Highspeed Mod

After buying a kywoo tycon on ebay for cheap I decided to get the printer working.
I testet the design for now 3 month and had no issues.

Main issues I had:

• Heatbed cable is unsafe
• Powersupply was not earthed
• Kywoo Mainboard has loud drivers on Z and Extruder
• Build Plate was not the best
• The plastic distance parts from the bed wer deformed
• X and Y Motors were pretty weak and I did not like the belts
• Extruder and Hotend was garbage
• Partcooling wasnt the best either
   

What can you expect with the changes?

• I run 5.000 accel, but 10.000 are also possible 
• I run 25mm³/s max, but testet it also with 30 mm³/s
• Because of the use of EVA3 many others extruders or hotends can be used
• I have good print quality and part cooling
• I use 10mm belts and stronger motors
• all the electronics are in the box from lh-stinger

Some tips and tricks:

• I use 257mm x 257mm pei sheets from bambulab
• I changed the bed distance spacers with 8 or 10mm metal spacers and 1mm silicone spacers. So I could achive a kinda flat bed. 
• BL-Touch worked much better for me than 8mm probe. (for high temperatures)
• You can use any other eva 3 compatible hotend or extruder. If it fits in the x-gantry.
• I use fysetc usb adxl
• I use manta mp5 mainboard -→ maybe I find the adapter for the electronic box and will post it here…
• My holes for the linear rails were not aligned correctly so I put them directly on the extrusion.
• I made z on 2 separete drivers to use z-tilt
• I changed the z-couplers to more flexible ones, because my leadscrews are not straight.
• My fans are 5015 from gdstimewith 8500rpm. 
• Because of the y-gantry most extruder/adapters wont fit, I tried many different versions.
  If you like bowden, than the hotend from the 3d printer “the 100” fits kinda well after some modifications. 
   

Noteable things:

• I tried klicky but had no space in me enclosure. Could work because bed can move quite far on y
• You loose 5mm on y
• Z-height is limited to 215mm max on my build.
• I trimmed the y-gantry where the yellow metal-enclosure was. This is not needed.

How to use the parts is all in the stepfile.
I wont write a full manual, but If you have questions just ask.
