I have built prusa before and now i would like to do CNC mill. But what electronics i need? Is there some lowcost sangunololu style boards for cnc stuff? Can i choose what ever steppermotors that have enought torque. And what about stepper drivers? Which software i recomended? This is low cost project so its also possible that i do electronics board by myself. Edit: Also this should be able tby eniq1on - CNC Routers, Mills, and Hybrid RepRapping
No i tried again after... 5weeks. Somehow now prints succes 80% of time. Dunno what was the problem. I think humidity wasnt my problem cause its pretty wet here now. ^^by eniq1on - Printing
Everything else works still ok but PLA wont stick into glass or kapton or anything. I'll get best result with kapton, first layer bed 75c and extruder 195, other layers 55-65 and 185. After few layers some corner gets little up and then extruder takes it fully off. OR if part dont have any sharp edges it may stick until layer 10 or something. I'v tried to use hair spray to get better grip but iby eniq1on - Printing
Picture Probably you have to replace this black big one (atmega 644P). I dont know maybe you may have some different problem but in my case that was the reason. Remember to fix the problem that caused this temperature stuck problem. You also have to burn bootloader to new chip when you get it and then upload firmware and so on... In reprap wiki there is instructions to all of these.by eniq1on - Sanguino(lolu)
Some updates. I bought kapton tape and tried to print onto it. It sticked ok but after some layers it started wrapping from corners. So i think problem can only be in pla.by eniq1on - Printing
Ok now i have made new bolt for extruder that helped a little about that incomplete prob. Also cheating slic3r about nozzle diameter helped. Now problem is that my orange PLA from Supply3DPLA.com just wont stick into glass. I have tried bed temp 30-90 with 5 celsius steps but it wont just stick. Now i have to use just plexi without heat.by eniq1on - Printing
Joo on PLA:ta ja oon vaihtanu paperin plexiin koska lasiin ei vaan saa tarttumaan millään ilveellä. Nyt ongelmana on se ettei viimosissa layereissä o otarpeeks muovii. Se näyttää kun se vika kerros ois tehty fill density 25% Tuossa on kaikenlaisia kuvia. Problems kansiossa on ne ongelmat. (ylläri)by eniq1on - Finnish RepRap User Group

ok now i can print parts pretty good with slow speed. Now problem is that last layer is incomplete. It prints it but it looks like its printed with fill density 25% or something.by eniq1on - Printing
Ok now i printed on plexiglass or some and it sticked pretty well. Now problem is that extrusion width is too small. How do i set it right? In slic3r there is extrusion width but how do i set it? If i want 0.5mm width is it 0.5 (wanted width) / 0.3mm(layer height) =1.667?by eniq1on - Printing
Its not going to stick... loosing my mind with this. tried all temps. Maybe my glass sucks then. btw my PLA is bought from Supply3DPLA.com if that helpsby eniq1on - Printing
Noniin tänään sain omani vihdoin toimimaan oikein ja tulostettua ensimmäisen kappaleen. Tuolla on kuvia ja nyt kehtaan sanoa rakentaneeni toimivan Prusan. Joten jos joku tarvitsee apua niin voin koittaa jotain suomenkielellä neuvoa. Kuvia wadesmall kansiossa on kuvat onnistuneesta kappaleesta.by eniq1on - Finnish RepRap User Group
WHOAA i did it. First printed part done. Pic will be released later Problem was that my springs in extruderbody wasnt tight enough. Now my only problem is to get PLA to stick into glass. Pics Springs was pretty tight but apparently not tight enough now there is bolt which i use to tighten it, lets hope that it wont break.by eniq1on - Printing
OK updates, now i took more pics about spitting problem. Temperature stays between +-1 when i print. I did new hobbed bolt but i cant say does it slip when spitting happens cause my printing speed is so slow. When i print bottom layer i can do it only with 10mm/s, dont know is this normal so you tell me. Pics hereby eniq1on - Printing
Today i tried with j-head and it worked pretty fine. Plastic didnt stick to glass but it worked well with printing paper. But i got still problem with spitting. When it has printed a while it starts to do morse code. Ill add pics later if i cant fix it.by eniq1on - Printing
Now i havent had time to try printing but ill get j-head hot end, then ill try again. And ill clean glass by some window cleaner.by eniq1on - Printing
Can humidity have so big affect that it wont stick at all? Well here where i'm using printer now is pretty big humidity level.by eniq1on - Printing
Prusa+ pronterface+ slic3r+ sprinter+ orange PLA+ heated bed+ glass+ diy hotend I have tried to print 0.5mm-thin-wall calibration part but i cant get it to stick into glass. Glass is clean and i have tried to use all different heights between nozzle and glass and also in layer height. Also temps different temps, bed 50-70 and extruder 170-190.

Now everything works fine with new chip. I have seen some posts with similar problems and thay have caused when thermistor leg touched heater leg. So thats maybe happened to mee also. My insulation in wires had broken.by eniq1on - Sanguino(lolu)
Itse sain jotenkin posautettua mikropiirini käytössä joten tuli takapakkia vähän. Tilasin mikropiirien kanssa samalla heatbedin. Itse kun rakentelin tuon hot endin niin sen kanssa on myös ollut vähän ongelmia. Tiedä vaikka ensiviikolla pääsisi ajamaan jotain osia.by eniq1on - Finnish RepRap User Group
I asked about my problem in #reprap. And they sayd that ADC (analog digital converter) is maybe broken. So i ordered 2 new chips.by eniq1on - Sanguino(lolu)
I got Prusa with Sanguinololu 1.3a and spiritner firmware. I'm using proterface as host software. Problem is that pronterface shows that temp is 59 even if i unplug temp connector. It also shows that bed has 130 temp and i dont have bed. It worked before today but after i tried my DIY hot ends it suddenly stoped working during heating. My computer crashed once but i'm not sure did it work afteby eniq1on - Sanguino(lolu)
Suuntaa antavat hinnat POSTEINEEN, eli jos oikeen dyykkaa ja ettii ja ei laske omalle työlle hintaa niin kai siihen ~300€ pääsee. Pultit, mutterit, tangot, ja rikat yms rautakauppa tai ~10-20€ Muoviosat emakers tai ~60-80€ (Kysele jos joku suomessa tekis halvalla "kaverille") Pursottimen teen itse kikkailemalla.

Nyt on muoviosat, hihnat ja laakerit tilattu. Huomenna rautakauppaan ja miettimään mistä löytys pursottimeen suutin.by eniq1on - Finnish RepRap User Group
Jeps, oon nyt tehny taulukon jossa on kaikki osat joita tartten ja lasken vähän hintaa. Suurin mysteri vielä on nuo muoviosat, pitäs saaha ne halvalla jostain mutta kun maksavat niin pirusti. Jos joku tuntee piston sydämmessään ja tahtoo auttaa köyhää opiskelijaa niin kertokaa, maksan matskut jne jne.by eniq1on - Finnish RepRap User Group
Eli tilanne on tämä, olen opiskelija wich means mulla ei oo rahaa tuhlata ja aattelin hankkia prusa mendelin. Joten onko järkevintä tilata valmis paketti jostain vai ostaa osat erikseen ja toivoa et on muistanu hommata kaiken tarpeellisen. täältä löytyy muoviosia näköjään kohtuu hintaan. Alan kääntyä siihen tulokseen että ostan osat erikseen ja kasaan pikkuhiljaa. Säästyy rahaa toivottavasti.by eniq1on - Finnish RepRap User Group
