OK no luck so far. ANY AB drive experts out there?

I have the spec sheets for both components BUT not enough brains to work it out.

You have a lose point in the original drawing. It is only doing what you told it to do. (;-)

Go back to the drawing and delete that point then recam.

OR just find and delete that piece of Gcode in the Gcode file.

Just a thought(;-) TP

OK if you are only cutting the part out and NOT the outline as well then what is the difference. Make a copy of the drawing then MOVE the 0,0 in the drawing to where you want it.  It would take about 60 seconds.  Then recam to have a gcode file like you want.

THen you still have the original drawing AND the as cut version as well.

Just a thought (;-)TP

Fiddle some more with it and seem to have the commutation correct and the encoder show zero offset. So maybe that part is right now.

Still no movement when using the control panel to test . something in the motor file is preventing it from accepting a vel number . I can load an odd file (not for that motor and the vel number show up in the test panel.

I hack at it some more tommorrow.

I am suely missing wsome just have not figured out what yet )(;-)

HUM still missing something here, No luck.   Th epahsing seems simple enought BUT the halls do not exactly line up so there is an offset but how much? That is the $100 question.

OH well maybe AB will have some insight, Yea right

OK found it it is at 3000 rpm which is the upper limit on the servo motor by spec.

I will study this some more. I am not positive the commutation error is total fixed.

I worked out the sequence from an example of both sequences  and do not get the error on start up. But still have not gotten it to move yet.

Thanks for the help, (;- )TP

General Mach Discussion / Re: RAPID TO STOP AT A WHOLE NUMBER (How To)

« on: September 22, 2012, 02:30:07 PM »

I don't think that can work with mach3.

You can jog a present distance with each touch(step mode)  BUT not  a random rounded up stop point.

That function would have to involve the planner to be able to deaccel to a known point.

Now you can use the MDI to GO to a point.

The normal buttons do not HAVE a 2 part sense they only work on the release of the button (;-) IF only it did.

Just a thought, (;-) TP

HIYA Hood yes I found your software trick with a web search. The  /A switch did the trick.

Worked out the commutation problem . Now I am trying to test with vel mode testing but I get a overspeed fault. The input field for setting the rpm will not take any values keeps sayin to enter a value between 0.0 and 0.0 .  I ener 100 but it rejects it.

Auto setup does not do anything yet(;-) Clip on start but nothing happens yet(;-)

Working on it. The AB software is strange compared to the old servo dynamics setup program (;-)
