In short I'm a new user to mach 3 I've bought the AJAX cnc kit got all the wires hooked up tuned my motors best I knew (Took a high end set of calipers and asked it to move 5 inches then I put in the real values from the calipers) I can even slow jog the motors around quite nicely now.
My question is my Fast jog refuses to work I can slow jog all day but no love on the Fast, I've tried this now on two computers both are core duo's 2.0 or faster only thing in common is the graphics are built in plenty of ram in both (Formatted both and reinstalled everything to make sure there were no problems)
I even see on the jog flyout that the little yelllow light is turning on.
So here's what I'm doing: I press the directional keys on the keyboard and it slow jogs fine. I press the Shift key I see the light turn on and press the directional keys again expecting it to move FASTER (this is the way you do it right??)
-
SET the slow jog percentage to 50%.
jog with keys motion is 50% of full rapid
Hold downSHIFT and press keys motion is 100% rapid speed
release SHIFT key and it goes back to slow jog when you press the key again
(;-) TP
-
So I try that but here's the stick. When I Hold Shift down and depress the directional keys reguardless if I have it set to 50% or 100% it does Not move. I release the shift key slow jog is back Depress the shift key and try to move nothing at all. (The light for fast jog is on)
-
SOunds like that might be a problem in the AJAX plugin side as the feature works here OK and you see the FAST jog light come on.
Check with AJAX for support problems

thanks I'll go bug Ajax awhile and see if they say it's mach's problem lol
-
It may be they don't support that function in their plugin. ???

I have a similar problem. I set the auto-override button so that I would be able to jog off of the limit switches after homing, but when the auto-override is in on, the fast jog will not work; only slow jog. If I turn off the auto-override, then the fast jog works again, so I have to go through the whole process of homing, moving off the limit switches, then turning off the auto-override. How does the auto-override cause this problem?
-
First thing is you should not have to jog off the switches when homing as the switches should be closed after the homing has complete. If you are having issues with that then you need to sort that first.
Issue with slow jog is because when you have auto limit override set the jog speed is reduced when you jog off a switch, this is because the switches get overridden and it is in case you accidentally jog the wrong way. You can however just jog slightly then stop jogging then jog again and full speed will be restored.

Actually, I neglected to mention that I don't actually have to jog off the limit switches. I can enter a command to move the axes off, too, but even after they are off the switches, the fast jog will still not work. I can try several times, but nothing changes until I go back into the input settings and disable the auto-override. There is also another puzzling aspect of jogging. When I originally installed the system, the jog mode would only activate when I used the tab key to show the virtual pendant. Now, for some reason, jog works anytime, regardless of the pendant. I don't know what I did to cause that to change.

Can you attach your xml please and I will have a look.
Hood

Well, this is where I always come up short. Is there an obvious command for accessing this XML? I've yet to learn anything about it. I'll also have to get back home before I can do anything, too.
-
When you have Mach open you should see at the lower right of the main page a profile name. Look in your main Mach3 folder for a file with that name and a xml extension, copy it to your desktop, rename to dmwright.xml and then use the additional options on the reply page to attach it. The reason you need to rename is the forum will only accept a file name once so it is likely if you use a standard profile an xml with that name will already have been posted by someone else.

I will do that tonight, when I get home. Thanks in advance.
-
Here's the XML file. Thanks.
-
I am not seeing the problem here.
What I was doing here was homing, pressing shift and then right arrow and X jogged away at 200IPM
When you home is it homing correctly, ie do you get the Reset flashing or LEDs on Diagnostics for the limits lighting?
Hood
-
It does home correctly. The LEDs light and it resets the axes to zero, which is the way I have it setup in home/limits. When I jog off, it will not fast jog. I have to jog off, then switch off the autooverride, and then it will fast jog.
-
So the Reset LED doesnt flash when homing? No error messages?
I dont understand where your problem is then as I have tried many times with your xml and it works fine each time.
Because you have the slow jog to 20% I need to also press the shift key when jogging so I am wondering if you have maybe modified the screenset to have different Hotkeys than standard? Not really sure how a keyboard itself could affect things but maybe try a different keyboard.
Other than that I cant think of anything else to try as I can not replicate it with your xml.
Hood

No problem. I definitely appreciate the effort. Thanks again.
-
Can you take a vid of it happening and post on youtube for me to look at, might get a clue.
Hood

No point in you bothering with any more. I can't imagine how a video would help, anyway. I've actually had the same problem on two different systems, although I think it was something else that caused it on the other system. I'm wondering if the breakout board itself is the problem. This board is the C10 from Keling Inc, and the other one was from Probotix. I also have another irritating problem I need to figure out, which is more of a problem, anyway. Whenever I turn on the power to the board, the relay clicks on by itself (Mach 3 is already running). I turn it off and a couple seconds later it clicks on again. I have to go through the process of turning it on and off about 8 or 10 times, and then it finally stabilizes and stays off.

Do you have any brains running?
Hood
-
No brains. I don't even know how to use them yet.
-
oh well, let us know what it is if you find the problem, might help someone else.
