Ca3PO4

exactly thank you very much.

Can anyone help me out , if someone has theis can you pass it on I cant find it .

Hi , iv got an Ultimaker original with self built heated bed upgrade, got glass ontop of the heated bed and I would like to add an auto bed level sensor the question is what kind of sensor to get , theres a shop in my town they got an optical and induction , which one is better? Does adding such a sensor guarantee that the bed will always remain level ? The second question is how do i connect the wiring to my ultimaker original main board, I mean would i just replace the z endtop connection with the new sensor or do I have to connect it else where ? are there any printable mounts for the sensor if so please please share Thanks for your time. Looking foreward to a reply.

Ok I have solved the problem . It was the print head screws too tight. After loosening those screws a little it works fine now .

Ok iv tried printing with the 2.8mm set under the filament diameter, there was significant improvment however I have also noticed something else, if i dont prime the nozzle before printing heavily there is almost no filament coming out from the nozzle. And when I look at the speed at which the feeder sprocket is turning its hardly moving at all. SO without priming manually before the print no Filament actually comes out the nozzle ! I checked the spring at back its 11mm , i even installed a new thermocouple. Still get this issue I am now beggining to think maybee its my firmware I flashed I have a self build heated bed kit so i downloaded a firmware that is not the original.

Aha I think you are right I just measured the filament and yes it is indeed 2.8 mm wow im shocked. Ok im going to see how it works with the 2.8 mm in setting and let you know. Thanks for the input .

I get the same thing happending when printing this in the New CURA. Bottom to middle half prints amazing but the trouble is with the top . Stops extruding at the stop ?

Hi thanks for replying sure ya here are some photos of the prints. Actually they come out nice but only for the bottom, the top as you can see has problems the printer stops extruding when printing the top. How can I fix this issue ? http://www.mediafire.com/view/qib88dbhhy9b98l/20161219_171908.jpg http://www.mediafire.com/view/31cqq5s2y3loxmq/DSCF1730.JPG http://www.mediafire.com/view/fdjdvrassfc7vc4/DSCF1729.JPG http://www.mediafire.com/view/ezdge7gdrd8hdyp/DSCF1728.JPG http://www.mediafire.com/view/dcrnf3wtb922vzm/20161219_171635.jpg http://www.mediafire.com/view/6om4pwcljpwvqak/20161219_171542.jpg http://www.mediafire.com/view/9hl076czhbyp2c3/settings.jpg

Hello I installed a 0.2mm nozzle and am trying to print a model which came out real nice with the stock 0.4mm nozzle however I thought that the 0.2mm would improve dimensional accuracy. Unfortunatly im having some trouble with the print I just cant seem to get good prints I mean I starts off alright but towards the end of the print I get problems it looks like under extrusion . Included is the model im printing with my settings in the gcode. Hopefully someone can recommend a solution to get the sharpest possible print. Thanks . Oh ya im printing 3.0mm Mouldlay wax.

I will try it with the aluminium thank for the advice.

Hi thanks for the reply , any suggestions for a fan duct which is best for printing small parts ?

O yeah i forgot to say the duct is printed out of PLA and i mainly print at low temps, 200-210C

Hi Im using the ultimaker original with a custom printed fan duct and its so annoying im on my 3rd one now because the thing keeps warping then eventually touches the heater block and melts, how can i fix this any suggestions please ?. I downloaded the fan duct from here its a pretty popular choice http://www.thingiverse.com/thing:17768 .

I just cleaned the nozzle , put it in a special burn out oven then blased it with a compressor. It was definatly clogged. Gonna try to print now with new colourfabb PLA i bought. Dont know if I should drop the flow rate from 100% to 70% to compensat efor the smaller 0.2mm nozzle ?

Sure i can do that , well i have printed 0.05mm and even 0.02 layer height and the prints come out great with the stock 0.4mm nozzle . Just trying to use the new 0.2mm. I was able to get a print done halfway through then i gues my retraction was too high and the platic was getting stuck in the white PTFE coupling , i cleared that jam and put back together but now i get no more plastic coming out of the nozzle end even though it is full of plastic inside so i guess it must be clogged. There could be some residue from other filaments i tried to print with before such as the mouldlay wax and or PLA .
