General Mach Discussion / Re: Drives falut out

As I see it and correct me if I am wrong in my thinking, if the drives fault then the original point of origin is lost and if this point has been machined away then there is no way to recover to that point again with out doing what i have been doing in the past or make a fixture to locate point of origin and start over from there.
 In the past when the above has occurred and i reset and tell Mach to run from there since it has no reference to point of origin mach runs the code as if it were homed at this point and does some nasty stuff to the part.
 As to the drives i use the recommended oils and went through the machine very thoroughly making sure it's up to snuff before trying to operate it, i can get the drives to fault by jogging if i do a short jog input by just briefly touching the key.

Hood and Terry
 I am currently using what Terry is saying, if the drives fault then point of origin for the part is lost in some part cases i have to put the point of origin in the center of the material so i hope this makes my point clear as to how much of a pin it is to reset the point of origin gets machined away. As to Why my drives fault out it's a funny thing if i use the machine every day there seams to be no problem but if i work on another machine for a time and not the mach machine it fault's until it gets warmed up or something to this not sure i have checked and replaced still the same condition i am using gecko servo drives the machine has 120 volt motors so i am running them at half power they were at 100 volt's and i am running them because of the gecko drives @ 50 volts don't know if that would effect this or not.

what you mentioned above is what's happening, but with a twist my drives fault and mach keeps feeding the g-code i see it and stop mach then i have reset the drives and rewind the code then try and find my exact home position which is not all way's exact. What i do is run the machine until it gets to a point where i can gauge how far it's off and then home it back to zero and jog the machine i do this on both the X and Y axis this is what i am trying to get away from.

if i do the above on pin one it would stop Mach and the G-code feed at the time the drives fault correct ? that's what i wish to accomplish when and if the drives fault out mach stops the code from going any further it all comes to a stop at the same time.

Thanks guy's for the help
so then all i have to do is take one of the input line's in the Lpt port wiring and tie it into the fault wire is my thinking correct?

Thanks for the reply, i have all my drives linked together so if one drive faults they all go didn't want any thing moving and cutting in only one axis i have break out board in between my computer and the drives so i am not sure how this effects what you have pictured above or how it's done.

Thanks again for the help

Hi Guy's
 I have a question for you mach guru's is there a way to stop mach feeding g-code when the drives fault out i hope i am getting my point across what happens is if the drives on my machine fault out mach keeps running the code and the part and now code won't match is i do a reset and run i have to try and set the start point and run the code until i get it to a point where i can check it's location then return to 0 make an adjustment and try it again it's a real pain thanks.

I know Mach is a control software and that's what i use it for now, but when i purchased my Lic it was promised that LC would come about to use for turn and mill there have been attempts by Art to address this and i am thank full for his work but it's not finished i do have Cad Cam software to use and like promech find problems with Mach in turn i found that i can only get 2.43 V to work well for turn.

Nope i think 5yrs is long enough to wait LT was supposed to be in LC which is now dead LT is not finished and dose not work well beyond rouging i am just using Mach for mill mostly now.
 Brain was the one who gave me the promise on lathe.

Join the crowd i have been waiting for turn for over 5 yrs now LT was supposed to come out and fix turn but now that's not coming when i bought my Mach LIC i bought it with the intention of using it for turning and was tolled then turn would be out in 3 month's LOL.
