No longer lurking, stepper motor question.

[simonparkes]

Thanks very much for the replies gents, once I saw the motors running I sort of guessed the usability of the motors was going to be quite limited to 3d printing, or maybe laser cutting, being as am on a very tight budget and have the neccessary item for the route I will probably go down it and forget about the possibility of prototype PCB routing. So in a way the money isn't wasted, I should learn plenty on the way, especially for when I do get the funds to build something much better and able to handle loads.

But, being positive, I have already learned something :)


Being as am not expecting the table to move more than 150mm x 150 mm I am planning on keeping with the cheap/learning amd using drawer sliders, which yes I know are far from ideal, I will also using threaded bar with long nuts (freebies) which again, while not being highly accurate, should provide me with movement..

Originally I was hoping to build a RepRap of one sort or another, but due to illness, my daughter is taking a year out of Uni which is where I was going to get the parts done on their 3d printer for material cost only, for which I think the parts I have would use been quite servicable.. Was also going to be able to get use of their laser cutter which I could have made a nice frame etc.. but hey ho..

the learning experience isn't really relative to using a CNC machine or getting one running

Agreed, the learning experiance for me is around the electronics and coding required to getting things whirring and buzzing, whilst keeping the "magic smoke" inside the various components :)

Far easier and cheaper to just save up and buy the real thing.!!

If you can show me mhere I can get the bits I have bought or the correct parts I have bought for under £30 I would agree with the cheaper... I understand what you are saying, in that I could (ok, probably will) end up with a 3axis cnc machine that isn't acurate and doesn't have enough power/torque to actually do anything other than shuffle around in a limited manner..

Kind Regards

To get the pointless outcome your going to get then yes I could show you how to do it for £30.? . . . I'd just point you to the stuff you've bought.!

I'm not being negative here I'm being realistic and speaking from seeing countless others waste the same time and money. You have Wasted £30 in the usablity terms and learnt nothing other than electronic experience that isn't relative to building a Modern CNC machine.

You speak about draw runners and threaded Rod without even realising the impact those things have.? They make all the above and what's gone so far even more pointless because your just digging a bigger hole. They are so inefficient your motors and therefore weak home brew drives will need to be driven so Much harder and they won't stand that workload without even more money and time is invested. Very soon your at the same money as buying the real thing and still have piss poor drives and cronky frustrating machine.!!

Like I say I'm not not being Negative and I also see where your coming from with doing it for the learning experience which is great. . . . BUT CNC is bit like the "Lord of the Rings" it will soon become your "Precious" and your under it's control.! . . . All the time it's trying to draw you to it's Master while dragging you thru the wasted lands of Electronic Doom sapping your will and money.!! . . . . . . But you need to be a Strong Hobbit and resit the urge to wear the Ring and throw the Shite into Bin and buy decent bloody drives. .
