Greets all; I am still in the process of 'calibrating' this thing, having whipped the motor speeds into shape with a lincurve between the pid.out and the pwmge.value in pins. Works nicely now.
And it only took another iteration to get the Z home position set about a thou off the face of the new chucks jaws. But X axis home_position is being a cast iron bitch, possibly because any HOME_OFFSET found in the .ini file would appear to be effecting the radius as opposed to the diameter, so if I'm off 5 thou, and put another 5 thou in the ini files value, I then have almost exactly the same error, but with a - sign. But to measure this is about a 20-30 minute job because to use my gauge, I must dismount the piece of .500" drill rod I am chucking up and adjusting to within 2 or 3 10,000ths true in order to find where I am at each time I edit the ini to add or subtract 2 or 3 thou. Looking at the hal-config, there is no place in its snooping ability to look at the effective offset in place, or to setp a different value there so the correct value can be found, and moved to the ini file with an editor in real time. So my feature request is to have this added to the hal configuration utility. In the meantime, I have another block of alu supergluing to the back of my gauge, that I will drill & tap for an adjustment screw that will allow me to adjust the tilt, and therefore the X offset of the gauge until the whole thing is at zero offset. This will have the added advantage of converting the gauge to a 3 point contact by having the rear contact the bed only at the screws rounded head. As it is, its so sensitive from the large flat area of that contact that I can see a film of Vactra squirted on the bed & wiped off. Or a bit of invisible fiber from the Scott towel I used to wipe it clean. I'll also know, from the error sign, which way to adjust the screw, something I can't seem to figure out when its within .010" of correct when using the stop LCNC, un-chuck the drill rod to get it out of the way of the gauge, adjust the ini file, restart LCNC, re-home it, then mount the drill rod and center it again, then run x in until it is gently holding a .0015 feeler blade, and hoping the display will tell me I am at .503" diameter when that occurs. Being able to tweak this with a setp in real time would be worth it in bottled deer or sliced bread at setup/calibrate time. Humm, could I use the touch off to set that contact point at .503" in the display, then find the difference that I need to move to the ini file in one of the vars at #5000+ ??? That would likely help considerably. Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
