CNC Milling DIY ,gusto kong mag-assemble, kayo ba?

[j2sip]

napamahal pa nga kaunti kasi I opted for 3-5 days shipping... pero ok lang, ayaw ko naghihintay eh hehehe...

Nice:) Wood router din po ba yung cnc nu?

[kinsa]

Kung unipolar ang stepper mo, linistepper is a good choice. Halos walang ingay ang motor mo.

[j2sip]

Ok daw yung linistepper pero it works best sa low amp high voltage na stepper motors. Good for cnc pcb millers but afaik mejo kulang para sa mga cnc wood routers na medium sized na.

[kinsa]

Depende sa motor, applicable cya up to 2 amps w/o mods. Mas ok pag adjustable ang supply mo.

Para cyang linear mode na power supply instead of switchmode. Hindi cya efficient but better ang current control, so smoother ang operation ng motor.

[kinsa]

Nema 32, nasa 7 amps nga

[j2sip]

Pwedeng ganyan ang power supply para sa hobbyCNC driver pero for simplicity's sake yung 36v ay ok na. Newbie pa din kasi ako sa electronics:)

Strictly for pcb isolation routing ang ginawa ko sir...

[JojoD818]

I have considered other brands pero after asking those who are really into cnc hobby they all voted Gecko hands down. Even those owning Keling 6050 types are still dreaming of using Geckos. I've learned my lesson, hindi na ako magpapatumpik-tumpik pa ulit.

Hehe nice one sir. PAg nag upgrade ako definitely geckos. PAhabain ko yung isang axis ng machine ko para mejo mahaba naman ang tatakbuhin pag g540 na ang driver nya hehe.

[JojoD818]

naship na siya kayapon, $437 yun g540 at 3 nema 23 stepper motors. yun shipping ang nagpamahal pero ok lang express na para mabilis makarating. yun customs na lang dito ang ewan ko... hay...

[j2sip]

I used pobox.ph's service. Quite cheap and they ship to the provinces. What sized is your router? I think the geckos are way too much overkill for pcb routing:) 

[kinsa]

Eto yung nagawa ko na 3 axis driver na based sa linistepper:



Inside: (driver, brains, power supply)



Transistor array:

Ganda naman nyan sir kinsa. Baka pwedeng ishare yung circuit:)

Better overkill, I've learned my lesson already and I'm not looking back. My router is a Paul Jones Engineering spindle.

[JojoD818]

very nice build sir kinsa, are you running your motors on 12V?

[kinsa]

Salamat

Adjustable yung supply, 2-24. Pero 5v lang ang motor ko. Using 8v para minimal ang heat.

Combined ko lang ang 3 driver circuits but using 1 pic to drive all.

Di pa tapos ang code, tini-test ko pa yung experimental na interface to emc2. Pero working na cya using parallel port. Tsaka using subset lang ng features of linistepper kasi  limited ang io ng pic.

Yung board limited ako sa max size ng free version of eagle kaya separate yung pic. Hack lng yung layout para mapagkasya

ah ok mababa lang pala ang voltage rating ng motor mo, ok yun mas mataas ng kaunti for the loses to be factored.

baka makatulong lang sir, meron dito dati post about eagle ba walang size limit. paki search and download mo na lang yun link kasi nasubukan ko yun and it works and walang size limits.

[kinsa]

pinulot lang sa basura ang motors, hehe.

Kicad ang gamit ko ngayon, proof of concept lang talaga yung ginawa ko. Instead na perf board, quick na design ang ginawa ko. kaya nakakahiyang i-post ang board layout.

hahaha ako overkill na para yun mga luma motor pwede sa isa pa smaller cnc.

Kicad is also nice, nahumaling lang talaga ako sa linuxcnc kaya di na ako lumipat.

[j2sip]

I'm really lost when it comes to technical terms:)

EMC2 ba yung linuxcnc? ano mas maganda sa kanila ng mach3?

Better overkill, I've learned my lesson already and I'm not looking back. My router is a Paul Jones Engineering spindle.

GAnda nung spindle. Ano ang ginamIt na mOtor dun?
