Although is not good looking , at last I spend half month to assemble it as attached picture . At the beginning , no help from manual , because the designer is lazy or busy to create the manual for us , he just give us the guide to reference Kossel Mini !!! So all the customer form a group to discuss and solve problem by themselves . So when install the frame , in fact I assemble wrong, have to disassemble 2 – 3 times again during install electrical part . At last , about 1 – 2 weeks I finished installation of frame and electrical parts , helped by our Kossel 800 seller group . But when setup software and calibrate the machine , we meet trouble again . Our talent team found a special way to calibrate by manual instead of unused G29 auto calibration . We can print now . Here is the calibrate test picture . Do you notice the tiny wire drawing , yes , it is not the perfect , but after create models , it is easy to remove by knife . If try to remove it during printing , we have to adjust slice software parameters at computer side . Anyway , I have not much time waste on it , I just hope to start printing lots of models , skip it now . In order to backup the plastic accessory ( designer’s plastic’s quality is not good and some start to crack .) , I print some spare parts . Then I hope to print bigger toys for my daughter , I start to meet big headache . ( A common issue for FDM printer ) ， Model edge cock ! Above pictures means I lost some model because of edge cocking . When printed Inverted triangle models , plastic material is easy to deform , the edge is probably raise then kick off the printer head . My score is : Lost three big model in one day . It says that ABS is more headache on edge cock than PLA too ! Our strong Victims team create a method to lighten this issue , add a D9 pc fan near the printer head as below picture . Just hope when material comes out , D9 fan can cool it down faster to reduce edge cock ! Printed a special model to install the fan . Now I am printing big model again , hope that it works ! Finally I have to say , custom Kossel 800 is not easy to play , but it is interesting , it attract me to waste time and money on it now !
