SO I NOW HAVE ALL THE PARTS NECESSARY TO COMPLETE MY RE-DESIGN OF THIS KIT!!! I AM WORKING ON THE NEW DESIGN AND WILL BE UPLOADING THE NEW DESIGN SOON - I HAVEN'T DECIDED YET WHETHER TO REPLACE EVERYTHING HERE, OR TO JUST CREATE A NEW 'THING'... EITHER WAY, YOU'LL BE ABLE TO FIND THE NEW 'KIT' FROM THIS LINK... ;-) <br>\r\nTHAT'S ALL FOR MY UPDATE RIGHT NOW, LOL!</font>_ <hr color="green" size="3"> <br> _<font color="red">BACK TO THE EXISTING COMMENTS FOR THE 'CURRENT' PROJECT...</font>_<br> THESE ARE THE OBJECTS I'M CREATING TO UPGRADE MY FOLGERTech KOSSEL TO MAGNETIC ATTACHMENT. <br> <font color=red>**_*UNFORTUNATELY*_ THIS PROJECT ISN'T TURNING INTO MUCH OF AN 'UPGRADE' AS THE MAGNETS JUST DON'T HOLD AS WELL AS THEY SHOULD. (AND THESE ARE *SUPPOSED* TO BE "N52" GRADE NEODYMIUM MAGNETS.) IT MAY JUST BE THAT THE GAP IS TOO MUCH BETWEEN THE MAGNET AND THE BALL BEARING. I TRIED TO MINIMIZE IT TO JUST .1MM, BUT FOR SOME REASON, BOTH CURA AND SLIC3R INSISTED ON PUTTING 3 OR 4 .1MM LAYERS IN THERE... AND .I HAVEN'T FOUND A WAY TO MAKE THAT SMALLER AS OF YET. SO FOR NOW, I EXTENDED MY ORIGINAL 'TRAXXAS' BALL-JOINT ARMS BY ~70MM (FOR ~300MM TOTAL NOW) AND RE-INSTALLED THE BALL-JOINT SETUP INTO MY PRINTER.</font>** \r\n **IF YOU HAVE ANY TIPS ON HOW TO GET THAT GAP DOWN TO A SINGLE .1MM LAYER, PLEASE LET ME KNOW** \r\n</font> \r\n **IN THE MEAN TIME, I'M PROBABLY GOING TO RE-THINK MY DESIGN AND PUT THE BALL BEARINGS ON THE RODS AND MOUNT 'DISH' MAGNETS ON THE EFFECTOR AND CARRIAGES. (V1.5?)** \r\n**ACUTALLY... <font size=+1>V2 POSTED HERE! <a href="http://www.thingiverse.com/thing:1064124">http://www.thingiverse.com/thing:1064124</a></font>** \r\n \r\n **ANYWAYS, BACK TO THE NOTES ABOUT THIS KIT...** OK, WELL THESE PARTS ARE WORKING, **BUT THE MAGNETS aren't holding as strong as I think they should.** I THINK THAT EITHER MY GAPS BETWEEN THE MAGNETS AND BALL BEARINGS ARE TOO BIG ***OR*** my magnets aren't quite strong enough (They're SUPPOSED to be N52 grade, but I doubt they are, as the 6MMx10MM ones seem stronger than the 10mmx10mm ones -- *stupid cheap Chinese magnets!!!*). \r\n SO IF THE PRINTER MOVES TOO FAST, OR THE PRINT HEAD GETS BUMPED, THEY COME UN-DONE RELATIVELY EASY. \r\n BUT, THEY ARE WORKING, AND I'M PRODUCING SOME NICE ACCURATE PRINTS, BUT I AM PRINTING A BIT SLOWER THAN I WAS BEFORE (I'm trying a 60mm/s print now, and surprisingly', it seems to be doing quite well. (But I was printing at close to 200mm/s with the stock Traxxas rod ends. - albeit a little lower quality, but it could handle it!) \r\n **UPDATE: THE 60MM/S PRINT FAILED AS ONE OF THE MAGNETS DISCONNECTED MID-PRINT. \r\nSO I THINK I'M GOING TO HAVE TO RE-DESIGN THIS UPGRADE, AS PRINTING *SLOWER* WAS CERTAINLY NOT MY OBJECTIVE...**
