General Mach Discussion / Re: parabolic equasion in axis formulas to correct deflection?

« on: July 15, 2012, 12:19:54 AM »

 1-(y/{maximum y travel}))^2*0
+2*(1-(y/{maximum y travel}))*(y/100)*{maximum deflection*2}+
y/{maximum y travel})^2*0

breaking this formula down and putting it in excel shows to me it has issues.

x =   0
y =   1
maxy =   36
maxdef =   0.1

x+ (1-(y/maxy))^2*0+2*(1-(y/maxy))*(y/100)*maxdef*2+(y/maxy)^2*0   
results=   0.003888889

1-(y/maxy)^2*0     =   1
2*(1-(y/maxy))*(y/100)*maxdef*2   =   0.003888889
(y/maxy)^2*0 =   0

Found you fixed it before I could post what I found, looks like the new formula works but I thought the sag was in Z axis. This looks like a straightness issue.

I would think first you have to base your calculations on machine home not on part home and then always program all part positions from there. Would be possible but a PITA but I suppose worth a shot. Damn confusing when you look at the Z dro and it is somewhere other than what you programmed because of the formula. Have fun, but Id take Tweaks advice.

Still learning to love the Dynomotion Kflop + Kanalog system and the +/- DC brushless servos, Lot to learn but it is quick, accurate & powerful.

General Mach Discussion / Re: IF you could add new Gcode functions to Mach3 what would you want?

« on: June 14, 2012, 06:19:48 PM »

I don't need G codes I need M codes 

Sync codes M70 M71 M72 for the Lathe

Presently a second computer running Mach3 would also be looking and using these.

Unless the "powers to be" can add gantry Y and B axis's to the mix and they could do concurrent but separate TP routines.
I love gantry loaders, conveyors and palletizers, just cant seem to figure a way to get mach to work with them all efficiently.

Thanks; this turned out to be the first part on my new Stainless Steel tubing and Aluminum plate built base, using brushless DC Servo's 
stout, fast, accurate machine, loving it already
Dynomotion Kflop / Kanalog system +/- 10volt

Did change the feed rates to all 30 ipm (could have went much higher) took 22 minutes to complete
0,0,0 is the center of the block, top face
I used the back of another test block (Plyboo) testing the CO2 laser.
Linseed oil finish.

Thanks again for the interesting design
Love those challenges

That's an new way to create the 3D shadow effect.
