G-Code, CAD, and CAM discussions / Subroutine confusion.

« on: October 02, 2010, 06:43:10 PM »

So I have never really understood the term ( i thought I did but a few words seem very similar here). When using an M98 to call a subroutine like this
M98 P00001 L10 (doesnt this mean to call up a subroutine #1? And loop it 10 times?)

Is this subroutine a defined amount set up prior? If yes where are they stored? I am ass/u/me/ing they must be set up at an earlier time and stored numerically.  I notice that generally when they are called, lower in the code it will give a definiition of what that sub is doing, is that like a local control you can edit on the fly? I mean by editing say the depth in the description of the sub at the bottom?

General Mach Discussion / Re: Homing Issues..Assistance Appreciated

You have a DM2400? I havent seen you on the Dyna page or Yahoo group. How long ago did you convert it over to Mach? Did you do it or someone else? Do you have any of the original parts? Sorry to be so nosy but parts and information are hard to come by. Any help would be great. John

CVI MachStdMill (MSM) / Re: MSM Beta quality Satisfaction?

Though I have not been on here on a while (a couple of weeks). When I was using MSM last it was working very well. If I had any problems they were addressed in a very prompt fashion. I thought the work being done was great and really appreciate the invitation to participate.

CVI MachStdMill (MSM) / Re: Re: How to get started with MSM Probing

Well I went ahead and placed a .1uf cap between the probe pin and ground on the controller and reduced the debounce to 0 (was working ok at 50). So far so good. I still get a stop occasionally but it is operating much better. But I dont know if it was the cap or just a better understanding. I think the cap must be doing something as it was very hard to complete a sequence with the debounce on 0 before. I can repeat measurements after retracting the probe and placing it back and remeasuring it. The measurements come out the same. If they do vary it isnt til the 3rd digit and mostly only the 4th, way accurate for anything I am doing.

Dave, upon a little more testing today. I can get the debounce down to less than 250 and be relatively consistent with the various operations. I am understanding most of it better. I do have a question about noise. Presently I am not running any caps on the inputs from my probe. i have read that using a .01 -.1uf cap can help with the noise issue. Is this the same as using the debounce or does it quell the noise some other way? Would this be an advisable way to help the situation in your opinion? If so, which value cap would you use of those 2 mentioned?

You know I read that in your guide and was suspicious of that concept. During the testing with a 10ipm fr and a 0 for the slow speed. I rarely got an error. So maybe its right? It doesnt seem right. I am still tinkering actively in pursuit of me understanding it or it working correctly. Probably a little of both. I am getting closer and it seems to be more consistent though occasionally it triggers or stops with no apparent reason. I say that because I dont see it travel the xy distance before stopping. Also during some tinkering without connection to my controller, just running the MSM in general. I could watch the dro's keep going in search of a face and go well past the 1.5" (" not 'LOL) and sometimes not even fault/error. I will watch closer, try to use faster probe rates and see. I have not experienced any overrun that caused any problems or any touches that were disobeyed. Mostly it just stops short of the target which seems to be within the specified parameters. I did try a few different debounce settings with no real conclusion yet. 0 was not possible it seemed but 50 was getting there.

Excellent. That was the way I percieved the debounce to work. I didnt know the calculations in time versus distance. I was thinking of maybe going to a max of maybe 500 and of course I probe at much slower speeds as I am not in any production scenario, maybe 10 and down to 1 for the slow speed. Tune as I work thru the steps. All of my cabling is sheilded and the sheilds are connected at the controller only but I always am trying to clean up the operation and performance in preparations for understanding a future bigger machine 1 day.

Also I see you refer to "down & over" probing. It does even show the probe doing just that in the screen but the green oval select point wasnt obvious to me. In fact I cant wait to go out in the shop and try it. Eyes arent what they used to be. Dont laugh too hard when I couldnt figure out why it wasnt following that toolpath. By the time I finish asking you all of the questions I will need there wont be anything else to address for the rest of the users. LOL
