General Mach Discussion / Dell PC any good ?

« on: October 13, 2009, 05:33:36 PM »

Not to sure how to start this but.  I have been having a hell of a time trying to set up my machine iv looked at vids spent hrs reading and trying all sorts of things to get this machine going the way it should I'm not talking machining just homing ,limits , and spindle control and up till now with not much gain for my effort. 

So i am know putting my problems down to the PC I'm trying to use. Its a Dell one of them desk top ones you see in office's with the screen sat on top and as we know Dell can do cheap pc's because they miss bits out of them to keep the price done. So iv come round to the idea I'm having problems because the PC I'm trying to use has not got a full set of marbles as in the port has only got the bare min of bits to make it work say a printer and nothing more what with it being a office PC it would of been on a network and not need the full port. would any of you say this holds any water before i go down the route of a diffrent PC I'm not willing to try my home PC as it a top line game machine and i don't want it in the workshop wear any thing could go wrong i can build a fast PC but for sure don't know much else ??

I'm hoping some one can help me.

Iv just up dated my Denford triac to Mach the and all was going well up till i got to homing, limits and referencing a long with one other silly little problem.

I can jog my the machine around all day from the key bored with no probelm of sorts but ill come back to that so now i iv gone in to homing and limits to turn my homing switch's on check i have no LED's on and that they light up when i poke one with a finger witch they do next i click on referencing the Z will move say 25mm and zero the DRO (when not even close to the switch)same on the y and I'm Lucky if the X moves at all referencing once more Z Y might do it right second time round if at all and once more x is the same then 1 on 5 goes it will do it all right ? but it gets even better if i go and turn on limits i cant do any ting all i get is Estop's all the time I'm lucky if i get it to start of for 5 secondes turn of the limits and I'm back to how i was just turning on 1 limit will do this never mind all of them.

So what is going off here I'm using pins 11,12and 13 on my break or bored.  is it because I'm using a unlicensed copy of mach3 to set up was just going to wait till i was up and going before doing so is there a few things turned of in my download ?

my next small problem is in jogging the Z i can jog Z- all day but as soon as i try to go back up to the top i cant hold the key down for more than 2 second es before the Z stops moving and i get a very unwelcome sound from the motor i have my motor tuning right down ?


any help please I'm going total mad here
