G-Code, CAD, and CAM discussions / CV and exact stop
« on: August 24, 2020, 09:38:21 PM »
I read in your manual, much after I sent the request that G61 and G64 can be used. One turns CV on the other Turns exact move on. 

My problem that caused the inquiry is:  On a clock face that is about 11 inches in diameter, I inscribe two circles out at about 10.25 and 10.5 inches in diameter, between them I inscribe the minute and hour marks, 48-minute marks which are shorter and 12-hour marks which extend from the inner circle to the outer circle.  In the first quadrant +, between 1 and 4 the marks are almost parallel to the line between the center and the 3. In the last quadrant between 9 and 12 the form a crescent shape.

I am trying to determine why this is happening as I can't cut clock faces with funny looking minute and hour markers.  It does not appear that I am losing steps as the end of the cut ends exactly at the beginning.

As CV is the default, I cut my speed down from 80 in/sec to 25, thinking it was rounding the last of the cut. (didn't make a lot of sense as half of the cuts were fine.) but worth a try.

Any suggestions would be appreciated.

General Mach Discussion / Re: keyboard shortcuts

As we all know hitting the escape key stops motion, another function is that it re-enables Jog movements after an MDI movement of any of the axis's, which is a problem I am trying to resolve.  My keyboard is at one end of the machine and my pendant where I do a lot of setting up and work is at the other end of the screen.  I may enter in an MDI string to move the head, and then go to where I normally work, after the movement, I may want to jog the head to a different location, which I can't until I press the escape key at the other end of the machine.  I want to program one of the extra buttons on the pendant to emulate the pressing of the escape key on the keyboard.  Does anyone know the OEM code or how I may cause an event that looks and acts like pressing the escape key?

Use the row below the top row, which starts with FILE I think,  to open and save files, screen sets or create a new screen these all work as they should, until a solution resolves this problem.  I sometimes forget and hit one of those buttons and it locks, the solution is to use ALT+F4 one time and it will unlock shortly afterward

Will this plugin allow me to modify Mach3 2010 Screen set?

Make sure you include a ground between the pc and the VFD (DCM on terminal strip) otherwise the process may not work.

No, the LED would display the change if I had guessed the right pin, but as you can see there is not a correlation between what my BOB pin #s were and the actual pin #s that the input to MACH 3 was seeing.  So using the auto detect function, I was able to determine the correlation as displayed in the table above.  Start auto detect, ground let say pin 11 on my BOB and auto detect would tell me that is really pin 6 for the input.  Stepping through each input gave me the relationships.   ::)

One of the problems with not using auto detect is you can not tell which pin you are activating until you hit ok,  Auto Detect tells you immediately right on the input screen, and also changes the pin number for you, all you have to do is keep track of which pin on the BOB you activated and write it and the Auto Detect response down so you can then wire the dang thing. Thus the table.

I do not think this is normal and I should have been able to know that pin 11 on the BOB would activate pin 11 on the input. and if I put that in for INPUT #1, that LED should have lit.  I have a new PCI Printer port coming and a new BOB.  It will be interesting if this all straightens out to a one to one relationship or not.  Let you know next week after I get the parts.

I know I get wordy with my responses, but it is important that all details are available to anyone else having a problem as this may give them some insight. :-*

Here is what I found for port 2 for this particular PCI Card:
I will list the LS name, then the  BOB pin number (which is actually the DB25 pin #) and then the input pin number for the Mach3 for each input:
LS Name   Cable Pin    MACH 3 Input #
X ++,         15,                2;
X - -,          13,                3;
Y ++,         12,                4;
Y - -,          10,                5;
Z ++,          3,               13;
Z - -,           4,               12;
A ++,          5,               10;
A - -,           6,               11;
Input 1,     11,                 6.

I used the automatic switch setting to find out which was the true input # when I grounded a pin on the BOB.  I stopped caring about the LED's once I could determine which hardware input was related to which actual MACH 3 input.   :)

I have it set up as EPP, but I will recheck.  It seems that pins 2-9 can be either input or outputs but not both at the same time, so seeing an input from one of those pins seems that it may be working However Pin 2 does not change any LED levels, which I found strange.  I will check out other cards though just in case.

I need 9 inputs to accomplish my goals of having LS for each end of travel on 3 axis and one input for zeroing the Z axis via a macro.  All inputs are pulled high to 5 volts. All inputs are set for active low. I only use pin 13 as an example, each limit switch and each limit X++ Y++ Z++ A++ X-- Y-- Z-- A-- and z zero which is not a limit switch but a 1" steel block that the tip of the tool touches and sets 1" as it's z position. (using a macro of course)

Pin 13 on the BOB should be the pin 13 on port 2 for setting the inputs.  IT IS NOT.  In this case pin 3 on the input setting will react to pin 13 on the BOB being grounded.  See below

When I short pin 13 to ground, I have an indicator LED go grey on the second row on the diagnostics screen.  It is the 6th one in from the left,  however on the configure tab, input setup, I have to put in port 2 pin 3 as the source to show anything occurring on the group of LED's below the port so Pin 13 appears to be pin 3 to the signal.

Thus if I set X++ to pin 3 of port 2 I have to short pin 13 to ground to have that X++ led to illuminate.  Port 1 fine and has been for a year, just downgraded to Win XP pro 32 bit so I could use the second port which by the way is a PCI card.

Because you have to change the input pin setup and always hit ok, it is a pain as you can only test one pin at a time.  By knowing the port 2 LED's row pin numbers left to right, I could then know exactly which input pin on the BOB is impacting which input in MACH 3.  There is not a one to one correspondence as indicated in the above paragraph.  It should be, all I want is to get this port functioning.  Perhaps there is a driver problem or some other corruption.

Thanks for that information, unfortunately it does not relate to my problem.  I am not using any outputs at this time, just trying to get 9 inputs for now to work with a connection to pin 13 not activating the pin 3 input and vice a versa.  I have ordered a second parallel port card, one that is isolated and buffered.  Perhaps there is a problem electronically, but I don't think as the inputs do works, only they are not related to the corresponding pins.
