General Mach Discussion / Re: mold making Mach3mill scaling
« on: April 20, 2012, 02:43:51 PM »
First NOONE creates molds that would not account for part shrinkage IF it mattered. (;-)

Scaling will work BUT you have to be aware of WHERE the reference point of the scaling takes place IF you are going to repeat the process at a different scale.  You really would need to be at teh exact center of the part for the scaling origin and that may be almost impossible to do in 3d space.

A one shot scale is fairly easy IF the resulting final part position does not need to be exact. BUT if you are needing to repeat it at a different scale at teh exact same position THAT is a toughy

It is NOT an easy process to master(;-)

Just a thought, (;-)

General Mach Discussion / Re: code to set home programmatically
« on: April 20, 2012, 12:03:24 PM »
Fred IF you have home switches then you have what yoou need to setup HOME.  It does not have to be at the switch positions. The Home/limits setup page you can apply an offset to the switch position to move the actual HOME to be anywhere on your machine.

That would be G30 home

You can also Specific where you want G28 home to be in setup.


NOW if you are talking USER Coordinates HOME then Move to that location and do a

G52 X0Y0Z0    OR
G92 X0Y0Z0    OR
G10 L2 P1 X0Y0Z0

and you have just set the USER home to 0,0,0

There IS one more option and that would be to create a Mcode that will set the Machine HOME at the position you are at. But you can ONLY set it to zero that way. AND I am not sure how any HOME offsets woul dbe applied.

Hope that helps IF not I will try again, (;-) TP

THe really strange part is it seems to flip flop as to IF it works or not WHEN I restart MACH3.  Some times it works some times it does NOT work.

Beats me, (;-) TP

As a test I am in the .062 version AND the single line pass thru worked just fine, (;-)

I give up, (;-) TP

SOunds like it is working RIGHT this time and passing through the MOD values.  Try setting the comparitor to  > rather than < to see IF it returns a Zero .

OR try taking out the second tier of values and see IF it runs with just the top layer thisw time.

Macropumps are not a problem I have already been brainwashed in that area(;-) I did build the same thing there to test it hoping to find some BRAINS logic stashed away in CB.

Hopefully I learn something new every day.

OK got it now.

Dro --> IF<100 = 0/1
Dro --> A * B =  *********   -->  output --> A/10000 -->  New DRO

I was close at one point last night BUT Iwould have never got the connection. SEEMS a long way around the block to cross the street  BUT I guess it is what it is (;-)

Thanks Ian, I owe you another pint(;-)

I am not getting anywhere My brain is locked in the logic loop and is NOT coming out. I just repeat everthing I did last night over and over again.

HIYA Ian, I went at it for a long time last night.  I agree IF we were tlaking about CB but Brains are suppose to be a ladder type logic and ladder does have pass through values as the comparitor is a gate so to speak.

I understand what you are saying about a comparitor output being boolean.  

Yes IF the gate was open you would get the pass through value, IF the gate was closed you would get NIL or zero.

I can get the value to be correct but not with using the comparitor

OR I could be wrong all together, (;-) I will work on it some more.

(;-) TP
