Great! I was following your blog entry [miscsolutions.wordpress.com] and entered "M558 P1" when setting IR probe... causing a crash on the next homing. Now it's safe.Quote

Seeing this error, version 1.09j :
Error: SetPositions called when DDA ring not empty

Thanks, Rick. I figured out what change I made in 1.09j that is causing that message, and I'll fix it in 1.09i.
The object height is showing as 200mm because of the G1 Z200 command in your end gcode. Try changing it to G0 Z200, or remove it altogether as you already have a G28 to move the head away from the print.

Appreciate the hard work. Moving from Arduino/RAMPS and using your IR sensor has simplified printing sooo much !!!

If you are getting different X and Y sizes, yet the auto calibration is giving you the correct heights all over the bed, then I think there is something significant is wrong with your build. I suspect that you may find that your X:Y size ratio may depend on the size of the print you do and/or the position of the print on the bed. You could try printing calibration cubes of different sizes, and at different places on the bed. Any adjustment you make to the tower positions to correct the X:Y size ratio is going to have an adverse effect on the flatness of the printing plane.

I suspect the problem you are having with XY ratio not being correct is due to backlash in your joints, or one pair of diagonal rods having unequal spacings at the upper and lower ends, or diagonal rods being not quite the same lengths, or something similar.

Any correction you make to tower positions to compensate so as to get equal XY sizes will have an adverse effect on bed flatness.

Did you ever try printing calibration spirals when you were using Marlin?

Did you try printing calibration cubes of different sizes and at different places on the bed, to make sure that the XY ratio was correct everywhere?

I agree with David here. Angular positions + delta radius + origin shift is identical to tower offsets + delta radius.
But nevertheless you don't get the result. I would try another set of calibration points, different number of points etc.

I have considered adding M665 parameters to allow the origin to be translated, in order to support delta printers with deliberately usual geometries. However, placing the origin at the centre fo the circle that the towers lies on work for both both standard and 'square' deltas, so I haven't done this yet.
Quote
Doesn't angular offsets just move the towers along the same perimeter of a perfect circle?
what happens to the math if you put one of the towers slightly inside or outside of that perimeter?

I mean changing the points in bed.g file. Put them in a square vertices instead of a triangle/hexagon etc. That might improve the calibration. Or not. Still worth trying.

Any chance I can ask if the 1.09j Raw Firmware files are available for download.

In response to more than one post above:
1. If you want to achieve the effect of moving the X tower a little closer to the centre, you can achieve that as follows. Your towers form an isosceles triangle instead of an equilateral one, with the base longer than the sides. So apply a negative correction angle to the Y tower, and a positive angle correction of equal magnitude to the Z tower. [Alternatively, leave the Z tower alone, apply a negative correction to the X tower, and a negative correction of twice the amount to the Y tower.] Then reduce the delta radius slightly. You can use school trigonometry to work out the size of the corrections you need. You will also get an origin shift of somewhat less than the amount you have moved the X tower inwards.

2. I didn't call anyone stupid. Even clever people occasionally do stupid things, especially when haven't worked out what the problem they are trying to solve really is.
