Hi have a look at the following post. youtube K9JoSJg7SIQ Regards Rod.

Hi A few more mods plus tidy up and weight reduction off moving parts. 1/ Manual feed wheel added to step motor. 2/Steel cross material feed shaft replaced with carbon fibre shaft. 3/Carbon fibre shaft and bearing added to support any pull on head by filliment that might effect print quality. Rod

Hi Just finished latest mod to Bowden tube feeder replacement to enable me to feed and print 1.75 Ninjaflex flexable filliment. Test prints turned out as good as PLA or better. Rod[/media][/media]

The bowden fan is an interesting idea. https://ultimaker.com/en/community/3435-new-fan-cooling-design#reply-19327 https://ultimaker.com/en/community/3435-new-fan-cooling-design#reply-19299 Hi replacing the fans with an airjet has worked out well for me as it givesme more control of temp when printing.Fans can produce to mutch air to the wrong place that can have an adverse efect on buildplate temp and nozzle temp resulting in bad prints and other problems plus they add extra weight to the moving printhead. I printed a Tourbillon watch by Christoph Laimer with the airjet with very few problems. Rod[/media]

Hi Thanks.

Hi just finished latest mod to enable me [/media]to remove printhead feeder assembly allowing me to change ptfe or to convert to use 1.7 filliment.By removing the single screw in the centre of the printhead an lifting up takes about 10 sec. Rod

Hi Feedhead weight now 49grms .I removed the material cooling fans scrouding ect a year ago and replaced with air from a pump witch fans out just below the hot end nozzle .The only fan i use is to cool my hotend setup whitch is not standard so should be a lot lighter than the original. Bevel gears are brass motor is the original ultimaker material feed motor.As to making feeder a kit all depends on the cost and feedback i get back.Now working on idears fo MK 2. Thanks all for your interest. Rod.

Hi print quality is very good. more consistant than with the bowden tube feeder. Rod[/media][/media][/media][/media][/media]

Hi all. Just uploaded my latest Ultimaker mod to youtube k9JoSJg7SIQ Rod

Hi. I got my Ultimaker 2 in December 2014 printed lots of items in PLA no real problems ecounted. Then switched to ABS main problem not adhearing to print bed tried various sugestions from forums ect slightly better results but not the complete answer parts were still lifting away from build plate. After many trials came up with a solution that gave me 100% improvement with my prints. A trial of 10 prints not one has failed so far due to the above problem. 1 / Remove and clean any material from the Ultimaker glass build plate. 2/ Onto the the area where the print is to be printed drop a few drops of High viscosity superglue(cyanoacrylate adhesive) With a razorblade spread this over the area to be printed on as thin as possible. 3/ Set the glass build plate temp to110C 4/ Load object to be printed and print as normal. 5/ Superglue residue can be removed from the glass bed with Acetone or if not required for further printing.
