i am 99% shure that all arduino boards and arduino derivates are made in china. also originals. it says on it made in italy. so on my chinese board says made in italy, but i am shure it will not see italy in lifetime... today everything is about money, so dont fool ourselves. i pesonally dont care where is made, most important is that board works...and its cheap.by woo - RAMPS Electronics
i have Z axis on my cnc milling machine approx 20 kg, 4-5 years on machine, no problems, just a lot of pure grapihte grease on it(M12 threaded rod),,,,by woo - Reprappers
why? why do you need step resolution of 0.00025 mm?? by so much steps on Z you just messing up with machine, firmware and have bigger chance that somethings goes wrong. @ full step you have resolution of 0.004 mm, when considered that normal layer height is 0.2-0.3 mm thats enough. there is a simple test. home your z axis, and put some mark on both Z couplers, on same place. after feby woo - General
you are doing it wrong... why 4000 steps? if you will good setup do the full step, thats 250 steps per mm. you ask why? on z axis you have 2 stepper motors. if they are running on full step they are sync. on microstep, everything is ok when first setup. then you ran print, no problem, you shut printer off. when you turn printer next time on, motors are still on some microstep position, anby woo - General
put any fan on motor and its ok. really no science here..by woo - Reprappers
too complicated, just put probe on hotend... dont get me wong, i didnt say its bad idea, just it cost too much. a lot of people drive heated bed on one axis, thats a lot of additional weightby woo - Developers
repetier fw+host, no need to increase pulse width, everything works out of the box ...with 24V powersupply and corect setupped driver.. to yvan: these eckstruder looks very cool, so why not try i printed it in pla because i didnt managed to print abs without warping...yet... but thats ok, because E3D hotend is icecoldby woo - Reprappers
i am new to 3d printing like you, just one advice. read wiki about calibration, maybe start with higher temperature, like 200, then lower it step by step.... it worked for me, if everything is calibrate as it should be with default slicer software settings print will be fine..by woo - Reprappers
well...machine is printing, and its printing good ...but still having problem with abs...cant get it stick to glass.. heated bed to 110 celsius, hairsprayed, abs juice, but still having problems with warping...this weekend i am planning replace all parts with upgraded , y corners for 10 mm threadscrews, stabilizers/adjusters for Z axis once again adjusting whole machine and finally printingby woo - Reprappers
just read comments on g code after you slice part, there is answer to all your questions...by woo - Reprappers
very nice design! can you please tell me how much plastic is needed to print one? im currently on job, dont have any sliciung software, and curiosity is a bitchby woo - Delta Machines
im using wood glue+water, sticks awensome! this glue and water, 1:10. only one coat on bed heated to 55 degrees celsius, and it can take a lot of prints. before applying i have cleaned bed with acetone to remove dirt or grease....by woo - General
so, let me say a few words. i have v 4.1 and i am very satisfied with it. i have printed 10-15 prints till now... i have printer for about one week, prusa i3 with full modified electronic. so i suggest to everyone, buy good stuff, it wil pay itself(hot end, printer is crap..). i think the best side of this hotend is, it cant be broken il buy another one soon for second printer one weirdby woo - General
i am pretty satisfied with warm up time. for pla cca one minute.for abs(110 degrees) about five -10 minutes. i turn on preheat, when i set up parts on board, slice them few minutes and it start to run.. i have few sheets of paper under heated, warmup time alot faster with some isolation under bedby woo - Reprappers
cheapest on ebay,they are all from same factory.. new couplers printedby woo - Reprappers
like on jo prusa i3 imges, but 5 mm id, now are 4 mm id nd its fine,,,by woo - Reprappers
so, i setted everything up to work, and started to do first print, useful print. stabilizer for yz, downloaded from thingiverse and another test cube....by woo - Reprappers
nice idea with magnets! hm....by woo - Developers
so be smarter. go to shop, ask for samples, tell them if they are good you will order large quantity, and they will be for free....simpleby woo - General
Hello! i am new to 3d printing, and have decided to try with repetier combo. so i have everything setted up, have some issues, also some good first prints.. can someone who has good working printer post here configuration file? Just for comparision, i am courious about some basic parameters like extruder acceleration etc, to see if i am going in good direction. thank youby woo - Repetier
if parts are printed good why not. just one detail. in this system motor is often spring loaded to avoid backlash between rack&pinion, because they will wear out. so i suggest to do the same thing.. when i searched for image, found another interesting conceptby woo - Delta Machines
got strange problem, i dont have solution for that yet... my prints are too low while x and y axis work perfectly @2 amps each and 8 microsteps(i tried also dry run @2.5A but motors were very hot after couple of hours), my prints are too low in Z axis. for example 30 mm cube is 28 mm high, i run Z motors @ ful step, 3 A for both motors. any solution? i run repetier combo, for M5 threaded rby woo - Reprappers
simple fact, i set my heated bed tolerances inside 0.03mm with meassuring gauge.. then i just EASLY lean hand on bed and it goes down by 0.2 mm.... that bothers me alot...but ok, we all learn on mistakes... i have @ home 10 mm smooth rods and linear bearings from another project , so right now adapting whole i3 for all 10 mm rods so that i dont spend not much money for this project.. i know,by woo - Reprappers
i have buyed regular 3 mm glass, heating it at 110 celsius, nothing happened for now. payed below 1 usd... i tried, and its all ok, important is to warm it equal, so no problem with pcb heated bed...by woo - Reprappers
these drivers need 24V, on 12 V they have missed steps...and they are working excellent. ebay, they cost 12-13 usd/pcs bad things , they are big, and there will be a lot of wires....good things, POWER!by woo - Reprappers
well. I can write to you a Bible about everything what is wrong with today 3d printers. but lets go in some order. put machine on straight, leveled table, on place where this machine will be whole time, if you carry machine from one place to another then steps below must be done each time you move machine... about aligning Y axis... well you need to fix (hm, whats word in english...)that stby woo - Reprappers
