##### General Mach Discussion / Re: Z axis design and Mach3 control

Steps per is irrevelant.

I'm talking about the display in the DRO.  It vascillates around between 358.4 or so, and 0.9 degrees.  Around a circle or square it goes fro 0.00 degrees to 0.9 degrees or so.

It should do the full 360 degrees - NO?  How far the motor actually moves is a number setting.  Right now, it is set at 50 SPI or 18000/360.

I mean that instead of moving to 90 degrees, 180 degrees, 270 degrees and then back to 0 degrees as the machine traverses a square pattern - I'm getting 0.25 degrees, 0.5 degrees, 0.75 degrees and then back to zero.

I'm guessing this is either a setting, or a programming glitch.

Did you ever figure this out?

I have a tangential axis and it wants to move within 1 degree as it goes around a circle or square - shoud be 360 degrees.

Steve,

Did you ever get this to work?

##### General Mach Discussion / Re: Upgrades, what a pain in...

It really makes me go crazy that EVERY time I upgrade my Mach3, R2.48 now, the highlyght of the worked path in the toolpaths disappears and it is impossible to judge how far the tool has come.

Have you figured this one out yet?

On my machine, I can load one screen set and the graphic trace works, load another and it doesn't work at all, and then load another and it works for the current contour but clears at the end of each cut path so I can see the current item being but have no idea where it's been.

All of this without turning Mach3 off, or loading another part.

I'd love to figure out this mystery.

##### General Mach Discussion / Two problems
« on: October 12, 2007, 03:35:19 PM »
First:

I have finally figured out the tangential set-up - almost.  In tangential, my A-axis attempts to maintain perpendicular the the cut path.  Sort of, anyway.  My problem is that the entore A-axis motion is within 1 degree of motion so that it is at 0 degrees when moving X+, at 0.25 degrees when moving Y+, at 0.5 degrees when moving X-, and at 0.75 degrees when moving Y-.

So, it works, but I need to get it to increase from 1 degree to 360 degrees so that it is moving 90 degrees instead of 1/4 of a degree.  Anybody know where that setting is?

Second:

If I use screens that I have built using Screen4, when I run a part it will show what has been cut, but then the display resets at the end of each contour so that I can't tell where I have been.  That is, it only shows what has been cut while on a specific contour.  When finished, the display looks as if nothing has been cut.

However, if I go to "View" and pick the 1024 screens, then run the same part - now the display showing what has been cut does not reset.  So, what's been cut already stays posted and does not disappear when I go to the next contour.  When the part is completed, the entire display shows that it has been cut.

Anybody know what setting causes the cut path to reset or not?

I found the answer.

I also needed to go to the "Settings" screen and turn on "Tangential Control"

You might try changing the settings for the G1, G2, & G3 Color.

If these are set too light, the display for what's been cut might be there  - just not visible.

##### General Mach Discussion / Tangential Set-up
« on: October 10, 2007, 06:41:25 PM »
This is really a new/old topic.  I've read a bunch of entries, and here, I'm  following along with an entry that Chip made in October '06.

I think I have this set up correctly.  My display is in degrees that roll over from 360 back to 0.  I can jog the A-axis, and it responds to a "Go to 0,0" command.

My set-up is a test board so there is no load on the steppers.  I have 5 motors as follows:  X, Y, Z, A (rotational), & B (Slave to Y).  The slave axis works perfectly.  When I run a pattern, I would expect that the A-axis would orient to be tangential to the X-Y position.  However it never moves.  Trying to figure out what I've missed.

Below, I'm following what Chip posted last year:

I've done this

General Config - checked A-Axis is Angular,  checked - Rot 360 rollover, checked - Ang Short Rot an G0.

I've done this

ToolPath Configuration - checked - A Rotations,   Enable, use Diameter for Feedrate.  Also, I set the Axis of Rotation to Z-Axis (I've tried all three)

For the next one, I don't know what Chip means by "rotational set-up 360 deg., but my SPI for rotational is 50 and it is 1600 for all other axes.

Motor Tuning, My A  Rotational set-up 360 deg., set-up X,Y,Z, 40000 step's, 10.002 vel,  A 1 Deg.=, 400.2 step's,  2500 vel, 144072 = 360 1 turn   144072 dev by 360 = 400.2

Re-Start, Mach3  -  Did it!

I'm not sure what the rest here has to do with basic set-up, but I did this as well.

Loaded Tooth1.txt Gcode file, No Rotational View Shows in Tool Path Window's, just linear view..
Regen Tool Path, Still No Rotational View, Gcode Shows Run Through, Jog A axis shows Degree Mode in Display.

Setting's Page, set Rotation Diameters A axis to 1.0000, Re-Gen ToolPath, OK, Now it shows Rotational View.

Default Start-up and Create New Profile or Closing Mach3 with a value of 0.0000 in the Setting's Page, Rotation Diameters on re-start will Default back to Linear View as it is now.

Help would be greatly appreciated!
