STEPPER ID QUESTION

[Imacman]

Hi All I posted this here in the Canadian club, as it is a product I just found at Princess Auto... Can someone tell me if this type motor is suitable for a Small CNC? below is the Link... it cam with a Belt Cog attached, a 6" belt, and another Cog to attach to it... it weighs about 1/2 lb is 115V ac 60 Hz, 250/300rpm I went to the company website... but can't seem to find any info on it.....the surprise is , the whole st up was $3.999 ( was $6.99) it's about twice the size of the steppers that come out of the older printers.... Can anyone tell me any thing about this?...

thanks In advance

No, it's totally unsuitable. It's 115 ac, constant speed, low torque. It's not usable with any controller on the market.

[Imacman]

Oh well... as they say..." If it sounds oo good to be true..."...lol... But for $3.99 It was worth it, for the 2 Cogs, and the belt that came with it!...lol... ( At least I'll keep telling myself that...lol.) Any Idea how powerful it is?... I may find a use for it...maybe for opening the blinds?

Cheers

The link in your post says 106 mNm. I believe that's about 15 oz in. It's in the same range as a floppy disk drive stepper. A typical stepper used for cnc is about 300 oz in.

What type of machine are you building?

I'll make a long story short... Ooopps...too late!...lol... Got bitten by the CNC bug about 8 months ago... started building / collecting parts then.... bought some great parts from George in Toronto ( Many threads on here from him )... so my design is an all aluminum & steel build similar to Georges machines... gantry style with a cutting area of about 28" X 40"... I'm using 5/8" 10 TPI ACME lead screws, 20MM Steel guide rails with an under Gantry full support homebrew set up, Single piece Aluminum Flex couplers. Thompson Bearings on the rails. and 8020 aluminum for the frame etc..... I'm purchasing the Gecko G540 4 Axis setup Kit from Ahren at cncrouterparts.com

At this point I have pretty much everything here except the electronics etc. I started the build... but in August, got to the point where 'Wifey" said...Ok... time for you to build a shed...Sooo.. Since mid Aug, My "Shed" has been under construction... it's 12 X 24, and is being built to be as 'Sound Proof" as possible.... drywall/ plastering etc, will be complete by end of this weekend... then I need to set up some work benches & get organized.... finally then I'm back to my build..Whew....lol... I've ordered a BF20lv mill to help me out in my build, that should arrive the end of November....when the shed / shop is completed, it will have a main work area, a computer station, and two small 5 X 5 rooms one for the CNC, the other for The mill. Plan is to finish the CNC first, then use it and the mill to make parts to CNC the mill and outfit it with the same setup from Ahren..... I'm told I don't need to buy two GeckoG4540 drives... I can install a switch/hub and run either machine from one computer & drive...but I'll have to research that a bit more...

Soo..it's been a bit of a long road... but as I'm sure you're aware....once you get bitten... there's no going back...lol.... it's costing me quite a bit more than I had first thought....as I watched my first Youtube Video of A CNC in action...having never heard of one 5 minutes before that!...lol... I've made all the same mistakes as everyone, and by the time the CNC is done...I will have enough parts & material to build two more...at least! ...lol....not by choice... just a fact of life in trying to run before learning to walk...lol ( still trying to master crawling at this point...truth be known .)...lol


Thanks

Sounds like an interesting project! But since you're buying a mill, why not cnc it first? It will be much more capable than the gantry machine when working with metal.

I'm in the middle of CNCing my SX3 mill. It's taking a very long time because I did not have time to work on it since moving to Toronto. But the basic ball screw and motor mechanisms for the mill are done. I will be designing my own stepper driver next.

Now that you mention it.... it may make more sense to CNC the mill first. I need to get my actual step by step plan thought through, ad organized... right now I'm trodding through the...ok...the electric service must be hooked to the shop by wednesday for the drywallers on thursday...lol.... I have my Construction engineer hat on...till the shop is complete... ( gonna be throwing that one at way at that point...lol... structural building construction...is not my cup of tea")... but it's one of the things that I;ve got to go through...to get to the next step. Buy you suggestion makes a lot of snese....I can do more for the CNC on the Mill, more accurately if It's CNC'd from the start, plus it will cut my learning time. Cool. Man... I Love this site :: )
