General Mach Discussion / limit switch help

Limit switch

--------------------------------------------------------------------------------

I have a limit switch that persistently trips during a program and requires me to stop the program, re-reference etc. I need some help in trouble shooting this thing. Following info might help:

Mach for the controller

Micro switches for the limits and home combined. A total of three dual purpose switches.

Mach does not indicate which switch is tripping.

Switch wires are shielded and grounded with the only bare area just before the screw terminals.

X and Y switchs are mounted upside down with the plunger hanging down.

Z switch is mounted with the plunger horziontal.

Wired for nc.

Due to Mach allowing it, Z and Y are using the same pins but when referencing the axis reference at different times.

Limit are set so any switch will Estop the machine.


Any help would be appreciated. I am at a loss and this is costing me precious time.

Mike

Switch is a Omron with a .016 pre-travel


General Purpose Snap Action Switch, Actuator Roller Plunger, Panel Mount, Maximum Operating Force 8.8 to 12.3 Ounces, Maximum Pre Travel 0.016 Inch

H Art/Brian,

How do you like that new name?

I tested the config and tuning on my home pc, which of course is not hooked to a machine. My machine steps are 3772.5 per inch. In my current xml setup of Mach 2 and 3 using 25k, my rapids are 348ipm. Before I moved over to Mach software, I was using a full or half step system and have seen this machine run at 1000ipm. The ramp up anddown was way long, but it did get there and was impressive to this country boy.

With that said, I have noticed that whatever kernal speed I use my home pc seems to work fine but I also noticed that the rapids are always real close to what the velocity is set at. Forgive my ignorance but is this what determines the rapid speeds within Mach? If so, will using a faster kernal speed actually translate to faster rapids or will I be limited to my 348 ipm now used in Mach2/3 ?

In other words, since my my machine is currently about tapped out at the 25k rapid of 348, when or if I change to a higher k say 60, will I be able to retune to a higher velocity without loosing steps, or will I still be limited to the 348 even in the higher kernal?  BTW I am using steppers.

Hi drut,

Do you have the wiring diag for your motors? You will need to know which wires correspond to the a/b configuration of the posted pdf file.

Thanks Wayne.

I'll place the link over on the zone so people can see what is possible with mach software.

Hi Wayne,

I think so but the site is DirectX and keeps locking my system. I have the latest DirectX downloaded but sometimes it just does this. Are you the guy who owns the site? If so thanks for answering. I was trying to show a fellow over on cnc zone what Mach3 was capable of and remembered seeing a site somewhere that showed a motorcycle engine that was in production that was machined with mach3.

Modified entry: I have noticed that in my scans of quarters and dimes that every other line is shifted a tiny amount along the x axis. This must be, I presume, due to end play of the x-axis leadscrew (what else could it be?). I am glad my machine is that tight!

Actually this is a function of the probe plugin for Mach3. I have probed several parts and I have the same thing.

, you can tie the string to your toe.

You mean you actually use 13 lines at one time or do you just use one of your toes


Tetra
 nice idea on the probe, i had a different way of doing this but so far have not had time to finish it, but yours looks easier. It would however need a redesign of my probe from the ground up to do it your way
Hood

Hood is your's the one that has all the electronics on the outside of the body of the probe? The one that looks like some sort of space gun or something? If that's your's, then I think the melding of the two designs would be a huge step forward. The one with the electronics stops the false triggers with the probe stuck in an open situation and crashes into something. I just read last night that another person on the zone had crashed their probe.......though I think it was due to another reason.

Hi Mark,

I have been following this thread for a while. I appreciate the work you are doing and the time you are taking to get this thing working correctly and accurtately. One thing that has intrigued me about all this is the software you are using to manipulate your point cloud. I did a search and found it but would like to ask a couple of questions. I feel this is pertinent to this thread since it does us no good to get a point cloud and have to way to use it. I have imported into Rhino and have one product we modeled from those points but the time involved was too long.

Can, or would you be willing to do a quick overview of the map software that you use as well as the steps taken and the type of file you end up with? For instance, the portion of the coin that you captured. Is that a machinable surface that you created?
