First, the joint 0 following error is related to your ini settings, and the max speed or acceleration are set at too great a value for the axis generating the error.
At first sight, the code looks ok, but I would try making #<cnt> a global variable #<_cnt> G10 L20 P1 might work better, as co-ordinate system numbering starts at 1 for G54 Marcus On 18 Mar 2018, at 05:27, Ralph Stirling wrote: > Why oh why does my looping program zip > right through my moves even with G61.1 > exact stop, and an M0 at the end of the loop? > Not a single move gets completed: > > Here is my test program (testing my polar > coordinate machine, doing 90 degree rotations): > > (AXIS,stop) > (AXIS,hide) > #<cnt> = 0 > O100 while [#<cnt> LE 4] > > (print, start) > G61.1 > G1 X15.0 Y30.0 F1000.0 > > G1 X20.0 Y20.0 > > #<oldx> = #<_x> > #<oldy> = #<_y> > #<x2> = [#<_x> * #<_x>] > #<y2> = [#<_y> * #<_y>] > #<x2y2> = [#<x2> + #<y2>] > #<at> = [atan[#<_y>]/[#<_x>]] > #<theta> = [#<at> - 90.0] > #<rho> = [sqrt[#<x2y2>]] > #<ct> = [cos[#<theta>]] > #<st> = [sin[#<theta>]] > #<x> = [#<rho> * #<ct>] > #<y> = [#<rho> * #<st>] > > G1 X#<x> Y#<y> > G10 L20 P0 X#<oldx> Y#<oldy> > (print, var 5222=#5222) > (print, end) > M0 > > #<cnt> = [#<cnt> + 1] > (print,cnt=#<cnt>) > > O100 endwhile > M2 > % > > The output I get is: > > Emit interp-run > Emit interp-run > start > var 5222=-40.000000 > end > cnt=1.000000 > start > var 5222=-80.000000 > end > cnt=2.000000 > start > var 5222=-120.000000 > end > cnt=3.000000 > start > var 5222=-160.000000 > end > cnt=4.000000 > start > var 5222=-200.000000 > end > cnt=5.000000 > > joint 0 following error > > With nary a pause.
