I need some drawings/design idea of your turret .
Do you have any links or PDF of the machine or turret?

remember that the m6 calls for the start and stop macros for the tool change

one thing about the hellfire's turret i would like to know is that "does it has a worm and gear"? or just a stepper attached by some sort of reduction pulleys + timing belts?

Hi Jasminder,

You could still use a DC motor and only need one switch running on a cam or an optical switch with a slotted disk.

Dan

I am sorry to say but then how mach3 will get a datum point for let's say tool no. 1.?

hello dan13,
My god, you gave him a really good idea. (thanks for that because i am gonna copy that too)
I am making a similar turret but i was considering a dc motor and 8 switches to index the turret and that means a lot of wires and input/outputs to mach3. Now i will also use a stepper motor for the indexing and locking of the turret. (you are very right that using the incremental mode for the stepper will not care for the missed steps that are surely  going to be there when the ratchet and pawl will meet.
maybe i will need some help from you on the macro's part later.

thanks,
jasminder singh

I live in Florida and I can tell you without a doubt heat plays a big part of Machs (computer) stability. During the cooler months no problems. But as soon as it gets warm things can get a little funky. I now have an air conditioned shop (yea) and no longer see any glitches or hangs.

Derek

thanks for your input derek.
But i have a 900 sq/ft workshop that i cannot afford to AC completely. Even my own living room is not AC at home. This CNC lathe is going to be lucky to have his personal AC to chill it's hot a**.

Look at this guys:

http://www.ebay.com/itm/PID-Digital-Temperature-Control-Controller-Thermocouple-0-to-400-/250984126629?pt=LH_DefaultDomain_0&hash=item3a6fd1d8a5

This is a very cost effective PID temp controller (it is being sold from china but is made in japan and can turn on/off an SSR to switch on/off the fridge i am gonna use) what do you say?

Points i am going to implement:
1. Shield wires.
2. Good quality closed loop temp controller to keep the temp between 30-40 degrees.
3. Small fridge for the cabinet (today i made a phone call to a friend who repairs fridge and AC to look for a ~90L fridge for me and he laughed after i told him what i need it for)
Anything else i should care for?

yes Jeff and Hood, the dust is not really harmful for the PC if it is just dust. But we cut and grind a lot of casting iron in our workshop that produces a lot of "Conductive dust" that drives the Mach3 nuts. I am sure that 99% of my machine's stability issue is going to be solved after giving the electronics an air tight enclosure.

thanks,

Hmm,
I am glad to hear that the fridge idea can work. I am sure i can use a closed loop temp. controller to keep the temperature of the fridge a bit higher than the DEW point so i will surely give it a trial if i cannot get a panel air cooler for cheap price. For now i have 3 peltier plates (TEC) lying around and i want to try making a small AC with them but i am not sure if 3 of them are just enough to cool this cabinet (24X22X8 inches) :

http://s1186.photobucket.com/albums/z379/jasomkakad/?action=view&current=wiringenclosure.jpg

I have made this cabinet just and have not tried Mach3 after that. (does anybody see a wiring failure in the cabinet? Is the VFD going to effect the Mboard sitting a foot away from it?

But if i go for a commercial panel cooler/AC how much cooling capacity i need in the cooler?
Can anybody make a guess in BTU? from the picture (there is a 2HP 3ph VFD, 2 computer PSU, 1 Switching supply DC 20V 8A, Two stepper motors drivers)
please somebody make an estimate of the heat being produced in watts or BTU etc so that i can get an idea of the cooler type i need.
