General Mach Discussion / Re: SAVING WORK LOCATION

« on: February 20, 2014, 02:02:57 PM »

unless you have home physical limit switches, you will have to continue your search for repeatable results.

I suppose you could drive your axis to the end stops (X- Y- Z+) and call that the machine (G54) 0,0,0 then;
Once you find where you want the 0,0,0 position to be for your vice or chuck use a dedicated work offset (say G55) zero the new location. Don't forget to save the work offsets.

Then everytime you Boot up, you move your drives to the end positions (X- Y- Z+) and call that 0,0,0 choose the saved the work offset (G55) and then it knows where the vise or chuck was from the last time. Not advisable, but why not try it. Cheaper than adding limit switches, lol, just not as repeatable. Would not rely on accuracy but it might be good enough for your needs.

Kind of why we use home switches.   everything is relative to a known location and we always home a machine on startup or after heaven forbid a crash.

My point was what I seen in the file provided looked fine. All lines looked connected.
I just reported what I found and provided a couple of alternatives to see if there was a difference for you.
Sorry I've never used LCam, just trying to help.

Tangent Corner / Re: How would you clamp this?

Predrill the two end outside holes and bolt it to a fixture subplate using close fitting bolts for location. Machine one side, flip the part over and bolt it down with the same holes and do the other side. Two separate programs but uses the same datums. Closer the fit the better.

Looks to me like some kind of formula is active in X direction. Because it comes back to the same location on the left side.

Not much in common with the pockets if they are all supposed to be the same program. Something is real odd looking, that's for sure.

Pi=4*Atn(1)
X = GetDro (0)
Y = GetDro (1)
V=X/Y
BaseAngle = Atn(V)*(180/Pi)
Angle = 90-BaseAngle 'G68 angle for Quadrant 1

I tried it, but the computer was made for win 8 64 bit and the network card driver was not available for any other Operating systems.
Biggest issue is drivers for hardware on the mother board

I wrote a plugin years ago, (among other things) I use for alignment calculation. Gives me lots of data.
Setting the first location to 0,0 and then going to the second location I can see the angle to set rotation axis G68 to.
I first did it with a macro pump then went on to make it a plugin to add all 6 axis.
So yes anything (for the most part) is possible with Mach. Its just what are you willing to live with.

Crude but might be effective for you;
You could use the camera find the first reg mark, take a small pin to pivot on that reg mark, set axis's to 0,0  and then rotate the whole image manually. Moving in only one axis use the camera to align the second reg mark. Would work good with Vacuum tables.
