Title: "Limit Switch Triggered"
Post by: BClemens on January 12, 2009, 07:50:55 AM
Original post copied here....

Debounce set to 1000  - done that! Did no good. Probably something that I'm totally missing but I cannot see this problem on the machine end.

This machine conversion has failed. I cannot get past the "limit switch activation" in Mach3 and after spending a week on that problem alone, there is nothing left. The "combo board" wiring has been checked time after time and the limit switches have been totally rewired a couple of times with shielded wire. The servo motors run fine, no noise and will fast feed, just not very long. I have been able to home the axis and begin to run the 'roadrunner' then - 'plunk '- reset. The spindle has not even been started - cannot get past the limit switch problem and set-up.

I have read here and there about this problem and have tried everything that has been suggested. The hours spent are beginning to seem like a total waste.

What fails? The Combo Board? The cable from LPT1? (actually tried another of those). Cannot see what else could possibly be done with the limit switches and wiring - they are just switches! I don't detect any noise on the limit switch leads with an oscilloscope although they are advertised as 'floating ground' - I do see that they in fact are. The switches are series wired on each axis with a common ground and are active high with a 470 ohm resistor from the 12V at each input to the signal input.

I have other components to get working like a pendant and a VFD spindle drive but cannot even begin to start on them!

BTW - hello everyone!   ..... and looks like goodbye at the same time. Can't get it to work after all the serious precision conversion with ball screws, servo motor mounting and set-up....

Thanks,
Bill Clemens

Change your limit switches AND e-stop to active low. Reconfigure Mach input signals accordingly. (You may need to use pull up resistors to +5V (not +12V) on each of the limit switch and e-stop inputs).

Set the debounce to 25,000 (or even higher) and see if it works. If it does, then it's noise on the switch lines. This seems to be the most common problem I see posted, and it's not easy to tell you how to fix it.

Post by: BClemens on January 12, 2009, 09:46:49 AM
25,000 X 40uS....long time....

Interesting to change the limit switches and e-stop to active low..... so there will be 12V present until a switch is opened?

Thanks

Bill,

Do you see your swiches activated on the diagnostics screen when you trigger them?
Title: Re: "Limit Switch Triggered"

Yes, I see the yellow 'leds' light when the switches are activated.

I'm not saying to run the machine like that, but see if it gets rid of the false triggers. If it does, then it's most likely your getting noise.

Also, you mention 12V, but aren't they really wired to 5V? If they are 12V, what are they connected to?
Title: Re: "Limit Switch Triggered"
Post by: BClemens on January 12, 2009, 11:27:36 AM
This interface board is the Bob Campbell Combo Board that has 12V available at the limit switch input terminals for use with Hall or other powered proximity sensors. Three terminals: 12V, Sig, and Ground.

I just went through a driver update for both LPT1 and 2, and seem to be having less problems with the limit resets but LPT2 seems to be acting sort-of dead. I attempted to shift Mach3 over to LPT2 and absolutely nothing would happen... StarTech PCIP_LP parallel card.

The basic circuit I have in mind would look something like this.

Tweakie.
Title: Re: "Limit Switch Triggered"
Post by: tbriggs on January 12, 2009, 11:54:49 AM
I am also using the Bob Campbell board.  Most of the parallel port cards that I have used have internal pull up resistors so what I have done is take the limit switch directly into the signal input on the Bob Campbell board.  When the switch is closed it pulls the input to ground providing the  "active low".  One end of the limit switch tied to "ground" terminal on the break out board and the other to the "signal" terminal on the break out board.

I have used the proximity sensors and just plain ole switches.  Both work fine.

Hang in there!

Title: Re: "Limit Switch Triggered"
Post by: BClemens on January 12, 2009, 12:11:57 PM
Yes, 'hang in there'! If I was really a quitter, it would have quietly occurred about a week ago.... That wiring description is what I have and the switches are in the NC position until the limit is reached. That's what makes this so strange - having trouble with my switches staying at ground potential?

Yes Tweakie, thanks for the rendering! I used NC grounded normally switch wiring so when they open - limit - the signal is high (12V) and to make sure that it goes high I installed 470 ohm resistoes to the signal input to the 12V output terminals.

I have raised the 'debounce' to 3000 to see what happens. This machine can just sit idle and reset on its own!
Title: Re: "Limit Switch Triggered"
Post by: Tweakie.CNC on January 12, 2009, 12:20:38 PM
To follow my circuit recommendation you will need to use the n.o. switch contacts (or replace the switches if they only have n.c. contacts available) - the switches only close when the limit is reached.

A problem with raising the debounce is that the switch needs to be energized for the debounce interval to be recognized by Mach as a stop and by then the machine may have traveled to the mechanical stop position (crunch).

Tweakie.
Title: Re: "Limit Switch Triggered"
Post by: BClemens on January 12, 2009, 01:09:27 PM
Tweakie, yes that makes very good sense. The set-up recommendation was to use active high for the limit switches because of the fact that if a wire came loose from a switch that there could not be a signal nor would there be an indication until there was a crunch. But, you make sense about the debounce.... I do need to reverse the logic for the pendant that I'm in the process of setting up - CNC4PC basic pendant.
Title: Re: "Limit Switch Triggered"
Post by: BClemens on January 12, 2009, 03:34:02 PM
Looks like this Combo Board may be the culprit. This thing is making so much of its own noise, I don't see how a signal could possibly not get screwed up getting through it. Speaking of getting screwed.... I noticed that the follow ups from Campbell aren't much - probably knows about these boards. Certainly explains why a basic on or off switch cannot work correctly and sends noise into a computer. Cannot blame Mach3....

So, who makes a good break-out board?

Title: Re: "Limit Switch Triggered"
Post by: BClemens on January 13, 2009, 06:44:33 AM
Yes, I don't like the thought of giving up on the Campbell Combo Board but if it doesn't work...The box fits that board which means going all the way back to coming up with another box for a different breakout board, but if it needs to be..

Maybe I've got a bad one. I wrote to Campbell a couple of times, maybe he will respond with some remedy - try another board...?

I put an oscilloscope on the limit switch inputs to watch for some sort of glitch - never saw one that would have triggered a reset. At the same time the outputs were watched with another channel - they seem to be all over the place with no apparent frequency or amplitude so when some of this noise varies far enough - reset. There has got to be a remedy for this....maybe a leaky capacitor or one of these chips with a bad gate or something.

These combo boards are assembled by flow soldering but I see puddles of flux on some traces. I'm not saying that this was repaired before I got it but why would there be additional soldered joints to a circuit board that had been flow soldered and then totally cleaned? The soldering flux appears to be around the voltage regulators and the main fusible link. Have I been the recipient of the tailings of a once thriving business? Bob Campbell seems OK, but money is money if things are not going well.

Off subject... But anyhow, we'll get to some other tasks while this is sorted out. The LPT2 port in the machine computer seems to be outing where it should be inning.

Thanks,
WAC

I'm sure you have thought about this but I don't see it talked about anywhere.
Are you using shielded cable?? Only one end tied to ground. Common grounding point.
Make sure that the power wires and the signal wires are kept seperate and as far apart as possible.

I moved my machine awhile back and did not pay much attention to the position of
the wiring after the move and had bogas limit and estops till I rearranged the
wires.
I use CNC4PC bob. My only problem was my own.
Just a thought.

Title: Re: "Limit Switch Triggered"
Post by: BClemens on January 13, 2009, 07:47:26 AM
You could be very correct. The wiring to each switch was replaced when this problem began with shielded wire and they tie to the main chassis. I have noticed a small change in the frequency of the limit resets by different wire routing even then. I'm seriously thinking about ripping it all off the machine once more and rewire the switches parallel and active high as Tweakie.CNC suggested. It makes sense to the debouncing feature of Mach3 but the only hesitation is that a broken connection on a specific switch or wire is not known until possibly too late with NO active high convention. I have some four conductor twin shielded pair wire that would do well.

Thanks,
WAC
Title: Re: "Limit Switch Triggered"
Post by: vmax549 on January 13, 2009, 09:35:25 AM
I think you need to check your machine for bad grounds, bad ground strategy, no sheilding,etc.

SOme spindle drive put out a ton of noise that if not accounted for create havok for the electronics side. Especially the 0-5v logic side of PC setup.

SOME motor drives are very noisey as well and IF you stack the noisey drive up next to an open 0-5v logic board (;-)

As to the solder joints SOme manf have the basic board built then ADD in there own local devices of choice at a later date.

Just a thought, (;-)TP

Post by: simpson36 on January 13, 2009, 09:44:23 AM
If you are having any trouble with the second Parallel port, that is a big red flag and you may have a conflict in the computer. Check to see if the two parallel ports are sharing and interrupt or have an address conflict. IBM defined these many moons ago, but add-in cards often come pre-configured as LPT3 (and LPT4 plus COM3 etc, if it is a multi card) or otherwise break the rules. It may be that you are chasing a problem in wiring that the PC itself is generating internally.

I can tell you from experience that bad, cheap or failing PC power supplied can make a horrific amount of noise. So much so in some cases that you can actually hear it in the motherboard speaker!

Use the task manager to check the CPU utilization. If it maxes out, it probably would not be a good thing with such a timing sensitve application as Mach. If another process is runing with a higher priority, it can suspend the lower programs. Also check to see if you have antivirus or a similar 'watcher' program running which could be intercepting the LPT1. Parrallel ports were often used for file transfer and networking at one time and it is possible that security software is monitoring it.

The only other though I had was based on my recent discovery that a wireless network adapter was making the whole CNC go nuts. False estops, false limits, and the steppers would suddenly stall for no reason. Unplugging the USB wireless adapter made ALL of the problems go away instantly.

Something else . . and this may be a stretch . . is if you are in an industrial area where some company has radio dispatched trucks. If you are getting slammed by a powerful transmitter, it would probably behave exactly like you are experiencing because it would all look fine until someone keyed the mike and it would just be an amazing coincidence if you happened to be looking at your scope at that moment.

I am still a newbee at this stuff, but still, I would put a spotlight on that PC as a possible suspect.



Title: Re: "Limit Switch Triggered"
Post by: BClemens on January 13, 2009, 10:14:27 AM
This machine has not had the spindle turned on yet! I have a VFD and a three phase motor for it but haven't made the exchange from the single phase motor. I'll check the machine grounds and see that the computer case and the machine axis drive cases are grounded as well - as - all one. This parallel port problem may be that it was named wrong  -  I'll have to check on that. Seems to me that I did rename it LPT2 for some reason but it was installed as LPT3 originally and in PCI slot 3. This book PC is brand new, bought specifically for this machine. But, there may be some issues. I installed the additional LPT port a year or so ago and then stored the PC until a few weeks ago.

I get the active high/low convention mixed. I now have active high and you (Tweakie) suggested active low... The actual process is there and correct, I just keep calling it backwards. Someone said a few posts ago that his only problem is his own. Well, I must agree and I'm betting the same here. I have done something stupid that is causing these problems and it's also probably right in my face and I don't see it. 

Thanks for the help!

Just for your information, it does not matter what the port is called in device manager as far as Mach is concerned, you just need the address. You can put the address of what windows is calling LPT1 in port two in Mach and it will work as long as you set your port number in all of your setup as port 2.

THe active high senario is also a safety feature. IF you had a wire break in you r limit scheme the machine would trigger an error BEFORE you found out by slamming into a hard stop and the limit did not work.

I'll make up a 'false harness' in the connector for the limit switches and see - good idea. Yes, one of the tutorial videos from Artsoft explains the active high scenario as a built in safety. Mine are real safe - the machine won't run at all - but not for much longer I hope. I've got plans! A next project is back shopped right now waiting patiently for this machine - some redundant parts.

Alright!


 I believe I have found the problem (with the help of my daughter). I had loaned this machine (loose at the time) computer to her during her senior year, two years ago. She reminded me that she had configured a printer on it for some HS work. SO, During looking through "control panel" and "printers --etc." I noticed that the the printer was active with TWO documents waiting to be printed. No doubt, this LPT1 was being buzzed at some interval to activate the printer. I had forgotten about even loaning the computer......

Right in front of my face.  The printer was un-installed (needed to delete the documents first!) and this computer/machine has been functioning since 1:30 EST this afternoon without the first reset. The darned thing got a total going over (rub down) for my need - must be a hot female little mill. Good grief!

Now to continue on....

Thank you all very much indeed!

Makes me wonder about all these similar problems that I have spent much time reading. I don't remember reading this remedy. Maybe some of us don't want to the face the fact that it was our own fault for not thinking, remembering, or doing something at beginning in preparation for what we are about to do with the computer.

Anyhow; Thanks very much all  ( cause I'm sure to be back to you thinkers and do-ers with a question ot two) and great to be a part,

P.S. I'll most definitely give a sincere appology to Bob Campbell for blaming his Combo Board. BTW: Bob Campbell did get back to me with very positive and informative information about this Combo Board. He sold me! Works Great! Sorry for the doubt....needles to say.

Yes, my daughter had to remind me that she had used it a couple of years ago...something about a 'getting old' memory or something like that - can't remember that either. Old timers disease.

Tis unbelievable how nice it is to walk away from this machine for an hour or so and it is actually still in the ready when you get back! The good thing is that the remedy is known. It wasn't a group of fixes or a swift kick that made it right not knowing which it was that corrected it - I know what was wrong. I feel sure that Art or Brian have either spoken about this or written about it but I don't remember seeing or hearing about it - it's sort-of a common sense thing to check in a computer as well.

What!!? I thought you were serious too, so I've hired a lift to mount my mill on the ceiling....

Question: Is the location of HOME a matter of necessity or choice? On this conventional vertical mill, both X and Y are homed negative so the table homes away and to the right - it that correct? I've run CNC machines and presently run a Sciaki Electron Beam Welder that is CNC and I still have this question mark over my head regarding this. I rarely home the welder, only the work positioner but the gun is not - could be, but not.

Thanks,

Title: Re: "Limit Switch Triggered"
Post by: Hood on January 15, 2009, 01:19:17 PM
You can basically home any direction you want or even halfway on an axis if you wish. The thing that is proper is that your machine coordinates Zero position is fully X and Y minus. If you had an axis homing the opposite way then all you would do is put a Home Off distance in the Homing and Limits page for the amount of axis travel.
 Example,  if you had 800mm travel then if your home switch was in the positive direction the machine coords for that axis would be set to zero and any move would then be a negative number in machine coords. If however you have a home off set when you home the machine coords DRO would be set to 800 which would be correct in that Mach would now know you are 800mm positive from true machine zero.
 The same would be true if you had a home switch midway on an axis, you would just enter a home off distance equal to the distance from the switch and true machine zero.

 Hope that makes sense as its quite hard to explain.

It helps me to think in terms of the tool moving and not the table, or to imagine I am tiny and standing on the table so that I am 'still' and the tool is moving around.


My suggestion in this particular case is to split the difference and mount the mill on the wall instead of the ceiling. This way when you look at the table,  zero zero is the lower left corner . .  just like in a geometry text book.  :P

OK, I was writing while you guys were adding more tid-bits for great information. I'll let it go as it was written below....

 Simpson 36, The wall mounting leads to some peculiar problems - In actuality, I cannot think of any reason that the machine couldn't be mounted on the wall. Eye height would be good. So, steel toed shoes and a face shield would be a must. There's a benefit! The smoke would linger longer behind the shield - more effect - better machining visualization. YEA!


Thanks Hood, that makes very good sense. Very well explained. The ability to 'zero' at some distance from actual home would require another switch but may be a real time saver at boot-up time. A Mazak CNC at Jefferson Lab does a 'backward' home for Y (I believe) and that machine refuses to run a program at all unless it has been homed. It goes positive Y to 'home', then zeros negative to actual home. The Mazak is the machine that has led to my confusion about this homing business in the first place. X homes as you would expect; negative - table moves left. Y homes with the spindle to the far side of the table or positive......Have I misinterpreted what the machine is doing or is this description correct?

Appreciate it !

Post by: Hood on January 15, 2009, 04:34:01 PM
Machine zero should be like simpson says, if your table was a piece of graph paper the X0 and Y0 would be lower left corner so that is where your tool should be. So in terms of a mill, if yo are in front of it the table moved fully right and fully towards the column is X0Y0 in machine coords. If you have it the opposite way for any axis then you should enter a Home Off value equal to the distance you are away from that position. I have done a quick sketch below which shows the table position for X and Y zero.

Roof - ceiling and inhaling determines use and sex is determined by - ah - not doing what? .... I'm a US citizen, I know what's the right way!

All seriousness aside; This NC machine is going to be a joy! Just out in the shop primping at the wiring a bit. Placement is all important, I understand.

 Do these Gecko drives 'burn in' or 'learn' because the servo motors are totally quiet but will run like mad when an 'arrow + shift' is hit, and then quiet again when still?

I'm like a friggin' kid with a new toy! B Clinton knows nothing here.

 I use KeyCreator (CadKey) at work and have been working with them (Kubotek) on a post processor for the Sciaki welder (with visual basic!) so have picked up enough that I have made a post for Mach3. I'll proof it and pass it on here. Seems KeyCreator is not so popular as other CAD/CAM software but it works very well. The CAD portion is one of the best.

I'm an old guy but Jefferson Lab has provided me with a Dell laptop and bought a license for KeyCreator to work with. Kid with a new toy there too!

Thanks, maybe reciprocation? Hope I can help....

Presumably this thread is concluded, so this is officially not a hijack.

Send cash . . large stacks of unmarked 20's to:

Worthy Charity
My house
Texass

We take only a modest 92% 'administrative fee' and the rest goes directly to help under privileged Wall Street CEO's


Hood,

I see you are from Scotland. Simpson is a branch of Clan Fraser from the Loch Ness region. I learned this at a genealogy booth at my first highland games. You know, extra large burly-man types wearing skirts and competing to throw ridiculously huge objects the furthest. That's a story in itself . . for another time.

Yes, the thread is winding down....and again; I appreciate the help and good cheer (except for the mercenary, smoked up Texans among us). I've heard it said: Texas is a wonderful place except for the Texans that occupy it. Seriously, I appreciate the help!

BTW: Did you want those 20's printed on both sides? (not too funny - some government agent Internet monitor just perked up from his donut)

I think that we all deserve to see a routed or engraved 'Road Runner' after all this. Come on WAC make something real good.
