Does the motor make noise when you tilt it? Tuning the motor drivers is pretty easy: 1. Use pronterface to make the Z motor move in any direction 2.while the motor is "moving" Turn the "tuning-pot" anti-clockwise until the motor stops moving/make noise. 3. Press to move the Z motors again and turn up the current (clockwise) on the driver until the motor starts to move smoothly without noiby Sir.Fluffel - Reprappers
Hey! Could you tell me what problems you got with your printer? There are many videos on YouTube that shows how to assamble you printer! If you still have issues I would be happy help you via Skype. Hope you get your printer up and running!by Sir.Fluffel - Reprappers
Quotejamesdanielv the issue could be resolved by decreasing print speed for layer adhesion, and lowering the z height. lowering the z height would be ideal, but your back pressure will increase, so for first layer you will need either a higher temp, or to print slower so the feedstock does not skip. and if motor current is turned down so it skips instead of feed stock, then current may have beenby Sir.Fluffel - General
QuoteOhmarinus QuoteSir.Fluffel Everything is bought from kitprinter3d.com and I have compared it to others and it seems legit but I could be wrong... Could take some better pictures If you want! But I'm pretty sure the problem is in the bed adhesion and the bed level but I'm not really sure how you level the bed! Thanks! Ah, with bed leveling I have set it up with four screws in each cornby Sir.Fluffel - General
Hi! i will try printing with a print speed of 30mm/s to see if i get better adhesion. I will also try to clean the kapton tape with acetone, I have not adjusted the motor driver (drv8825) for the extruder motor could that be a problem? how high should the hotend (tip) be from the bed? I will print a fan holder for a j-head with mount for 3 fans. I use cura right now but im not able to controby Sir.Fluffel - General

Hi! Thanks for the answer but i dont think the fillament is the problem. Im buying my filamament from www.creedo.se wich is a swedish website with great filament! I think the problem is that my bed isnt level and the print doesnt stick.... Got any tips for bed leveling? Im using a heatbed with a 3mm mirror and kapton tape on top but it still wont stick I also tested glue stick on top of the kby Sir.Fluffel - General
Quotepushthatbolder Your nozzle seems too hot, I am printing my Chinese Filament at 190c without issue test your thermistor, is it reading correctly? it may be giving a lower reading. and extruder is actually much hotter than you think. Check the setting in your firmware regarding thermistor settings. or try this, Disable steppers bring temp down to 150 and try to hand feed the filament with tby Sir.Fluffel - General
Hi! I tested 185-190c and it works great! The termistor seems to work. the problem i have now is that the filament get "picked up" by the print head. I also get holes in printed objects in some places and "blobs" on other parts. pictures: Im now printing with: hotend: 190c bed: 70c It seems to be a adhesion problem but im not sure.... Thanks!by Sir.Fluffel - General
The feedrate is now calibrated. I've addded some more photos to the google drive link. I got some stringing and globs and other nasty stuff, i dont know whats wrong! I have tested diffrent tempratures but it dosent work.(175c, 185c, 200c, 210c) I got the best results with the temp over 200c. The the filament make small "globs" at 50% fill density. dont know what to do. Thankful for all the hby Sir.Fluffel - General
HI! thanks for the help. Im right now printing with the settings you recommended and its looking good! I have calibrated the extruder feedrate before but it seems to be wrong. The filament was 2cm of (30mm extruded of 50mm) but thats fixed now! The object is the makerbot gnome from thingiverse (http://www.thingiverse.com/thing:138642).

Hi! I dont get any nice prints from my prusa i3. The object got holes in it (see pictures) I also have weird lines on the "outside" if the object. semes to be a rertaction problem. the prints also take dubbel the time to complete (curas estimate is 30min the print takes 60min etc) please help Some info: 0.4mm hotend 200c on hotend 60 on bed marlin on ramps 1.4 printed with retraction in cuby Sir.Fluffel - General
Hi! what i ment was can i use a 250v 3A switch for the 16A the RAMPS require (turning the printer on/off) How did you learn to use sketchup did you use a guide or or just playing around? Thanksby Sir.Fluffel - General
Hi! I have ordered some switches and fans for my prusa i3 Can i use a 250v 3A for the RAMPS power and can i use both the 5A and the 11A "channel" on the same switch (12v psu)? I also want ot make a mount for the switches that could mount all 5 switches to the side of printer but i dont know how to make a 3d model ! The Switches: The Psu: The Fans (30mm) : thanks in advance!by Sir.Fluffel - General
