I could not find my inline breakout board, could I unplug the cable and test the voltages directly from it?

Mr.Chips

Not really const vel should be quicker.
If your still up PM your Phone # I'll give you a call.
I'll PM my # if you want to Call.

Thanks for the chat.
I took your advise and downloaded the latest version of Mach 3 and installed it.  And my slow jog problem is gone!!!!!  Hurrrray

OK on to the next issue.

No matter if I jog Y+ or Y- it always moves Y+  any ideas on that issue.

Hi, Mr.Chips

On the Program Run screen is the Feedrate set to 6.0 now, That may be whats going on, Mach defaults to that speed unless you put a F### speed in Config, General Config settings Page.

Try a MDI line move G00 X2 on your MDI screen, Should move at your Velocity setting speed.

Hope this Helps, Chip

"On the Program Run screen is the Feedrate set to 6.0 now" ?  Yes it was.

"Mach defaults to that speed unless you put a F### speed in Config"  I added F75 to the Initializing string and restarted Mach3.

Now the Program Run screen displays a feedrate of 75.  But the jog speed is still slow, not changed.

"Try a MDI line move G00 X2 on your MDI screen"  I did that and the speed is back on that command, but Jog is unchanged and slow. 

On the General Logic Configuration I see you have the Motion Mode clicked on Exact Stop I have Constant Velocity.  Would that have anything to do with my problem, hey I'm grasping at straws here.

Thanks Chip

Press the tab key and in the flyout windo type 100 into the slow jog DRO and press enter, it should now be back to normal. If its already at 100% then what is this "utility" you are talking about?

Hood

I changed it from 10 to 100 and the Jog sped is still the same at both settings.
I could not find the limit home utility again, I think it is burried somewhere in Mach3. 
Have attached a shot of what I changed just in case I did not understand.  Hey it happens.

OK I must have touched something I should not have because it will only Jog very slowly.

Here is the history leading up to this problem the best that I remember.

I was setting my Motor Home and Soft Limits.  And everything was working fine.  I would tell it to go to 0,0 and it would rapid then slow and stop right on 0,0 the same for G28 (think that is the Home code)  Hey this is nice and I liked the sound of the steppers when thay slowed.

I then started working on my limit switches (with soft limits turned off, no green box around icon), I would jog  and it would stop when hitting the switches all at the normal jog speeds.  These were beyond the Motor Home and Soft Limits but since the soft limits turned off I didn't think it would effect anything, and at the time it didn't, jog speed normal.

I then found a utility within Mach3 that woud automatically set the X+ X-  and XHome  (and other axis also)  I would jog (speed normal) to the X+ switch then click the screen it then stepped through the other axis. to do the same for the other axis.

I think it was after this that the machine would only Jog very slowly.  But I'm not exactly sure.

I think it was after this that my Jog was always in the slow mode.

General Mach Discussion / Mach3 Videos

« on: March 19, 2008, 04:12:43 AM »

I have watched several videos on the Mach3 video list and quite often they mention videos such as "Work Offsets"  and I cannot find them in the list.  Where would this one be? 

They also often mention the "Next video" and name it and again it isn't in the list.
Hmmm are there different lists of videos, guess i'm looking in the wrong place?

I really like videos it's better than the guide for me.

Today I learned how to setup Motor Home/Soft Switches.  But it took a few goes at posting my question on the CncZone to finally arrive at how to do it. I have the Mach3 guide printed out and if I only had it I could not have done it, so far the guide has not been very helpful to the new user.

So by putting the  G51 Xnn Ynn in the GCode and no matter how large the piece to be cut is, Mach3 will automatically size it down to be the  Xnn Ynn size.  Thats good to know too. 

Finally getting the feel of the terms used in Mach3. 

Thanks for you very good explinations.

Thanks Graham,  I really like to see something change after doing something.  And in the future you would have to do the same thing again.

So, the Gcode numbers displayed on the Mach3 screen do not change.  But when it cuts it will cut to the smaller size.

Hmmmm I need to find a DXF test file that is smaller than my cut area then do the scale, regen then cut and see if it really changes.  That way if it didn't change the size there won't be a problem.

It seems funny that after scaling you just have to trust it because there isn't any visual indication that it did not really resize the object.
