General Mach Discussion / Shuttle Pro V2 Keystroke mapping
« on: April 12, 2010, 02:29:40 PM »
I am a new user of both Mach3 and machine tools -- in my case a Sherline lathe and Taig Mill. I bought the Shuttle Pro to make it easier to run my tools in "manual" mode since the system I bought from Soigeneris is not configured for manual milling. Mach3 has a configuration screen which is nicely done but I am such a novice I am not sure which keys to configure for what behavior. Does anybody have recommended configurations that I could use until I get more experience and can customize for my own preferences? In particular I am interested in how to set up keys for changing jog modes, and toggling jog speeds. Whatever can be offered will be appreciated. Frank

Fine, I'm 57. Not a problem beiing well known. I can handle it and I can dish it out as well.

Ok, I am going to let this rest and just go over what guys have said with my machine in front of me.

Rich you said start "LT". Not sure what that means. Also, ever since I walked into the CNC machining thicket I keep seeing the acronym "LOL" . What is that supposed to mean?

Phil, you mentioned MachScreen. Is that a screen set or a tool for creating screen sets?  I don't have time right now, but as soon as I can I am going to dig into the NewScreen.zip that I was pointed to. Is that where I find the MachScreen you are referring to?

Thanks again, you have put a lot of time into trying to straighten me out and I am appreciative. Frank

Phil,

Thanks. That sounds fascinating and exactly what I would like to be able to do. I will dig into it over the next few days and hopefully not make to much of hash out of it What kind of MPG do you use?  Frank

I guess when a thread becomes a Hot Thread you know you have annoyed a few people.  Well at least it provoked some sarcastic humor which has me laughing. I probably would have found it funnier if understood more of the references. Maybe when I find that mentor...

Thanks for pointers on screen sets. Frank

Rich and Hood,

I really feel bad because I am making you waste time. I have read the manual, all three of them, extensively, repeatedly over the last month or so. I have avoided getting on the forum until I felt I was asking questions that I could not find the answers to in the manuals. (I am not saying the answers were not there, but that I either could not find them or could not understand them).

Almost everything you wrote in the last three posts I understand pretty well. In addition to your manuals I have read Briney on Machining, both Hayden and Hess on CNC Machining and Programming and I am a good way through Smid's Handbook on CNC Programming. I think I just am not good at expressing my question precisely.

I was referring to homing without homing switches. Your manual says, I believe, that you can enter data in all DRO's and hit Enter. So when I was trying to set up machine zero, I thought I should be able to do it relative to where the tool tip currently sits. So I tried and the system appeared to refuse to accept a value (which appeared to contradict what your manual says). So that is the reason for the question.

I think I understand offsets. I understand radius vs diameter. But what if you don't want to use an offset? What if you are running a simple program and you simply want machine zero to be program zero. I understand that that is not recommended practice, but I see no logical reason why you should not be able to do it.

I my specific issue I have little delrin rod that I am trying to turn and then cutoff. I want to do this repeatedly. Program zero is -.1" from the stock face so that I can face the piece before turning and cutting. I wanted to make machine zero - program zero and I wanted to do it without having to jog around the stock to y=0, I just wanted to leave it at x=0 and tell it where y=0 was (-.1 from the stock face).  This would make my repeated operation a lot faster.

So, I guess, from reading what you wrote the answer to the question is that no, you cannot set Home be defiining a location. You have to be at the location you are setting and the only value Mach3 will accept is zero.

If I haven't completely exhausted your patience I would still like to understand two other things: 1) what is a work coord. (from the Manual Screen)? Is the same as a program coord.? 2) when you are in the two Auto screens how can you tell if the Axis DRO is showing you macihine coords. or offset coords.?

Thanks. Frank

Hood and Rich,

Thanks for those helpful comments. I have so much to get on top of right now that I am not going to try doing my own screens. I think cycling up and down is useful and when I figure out how to do that will implement it. I love the idea that users can dig in and make modifications and look forward to giving that a try.  Frank

Hood,

Yes, in my item 3 of my request, I was trying to set the machine coordinates at a value different from zero. Are you confirming that you can only enter a value of zero?

Any comments on my question about how you know which coordinates the Axis DRO screen is displaying when in the Auto screens? Or the first one about what the Work Coords. button is for?

I appreciate you help. Frank

Ok, thanks for all that advice, but I don't know what it means to download a screenset. Of courses, I know what downloading is and I can guess that a screenset is some sort of template that dictates how screens are laid out, but what are the mechanics of screensets? I have looked in my iindex, no such word. 

Phil has pointed out to me the benefit of using the Find command in Adobe. I do that and find one reference. It is typical of the ambiguity that I find so frustrating about this manual.  It says, in passing, talking about the DriverTest utility that:

"Other programs such as a screen designer and a manipulator for screenset files are available as a separate download."

Nowhere, as best I can tell, does it tell you what a screenset file is or how it is used. Can somebody point me to some instructions?  I hope these aren't unreasonable questions. Frank
