dual YY axis problem

Check out section 6.1 from here linuxcnc.org/docs/html/config/ini-homing.html#_homing_sequence

I have a dual y config example that I can send tomorrow if it is useful to look through

I have the same style machine with xyyz. I have edited your ini and hal to match what I have in regards to the joints / axis, and then the homing sequence that I use. I have all the homing parameters commented out because I use inches not mm, have a larger machine, probably different homing location, etc. You can use these as a reference just be sure to change the values to mm. Be sure to save copies of your original files before using any of the settings I have changed.

thanks this new ini and hall working little better, but not understand i start all axis show 0,1,2,3, if ewery number axis home axis change display XYZ
and machine-homing have joint0,joint1,joint2,joint3. but not homing all. not can use if bush homing joint1 no move joint2,=Y axis both motor together need move.
if homing all 4 joint manual then come display have XYZ and select Y and continue move motor both motor Y run, this is ok, but homing not can do if not Y motors can both homing together, now have all motor one only homing not both Y motors sametime.
or homing not need move motors only display numbers homing. i not know.
machine-homing not have selection homing all axis.
and all homing button not move motors.
select axis Xor Y or Z and bush homing not move motor, same all motor.     but zeroing display 00000 and come home 0/ mark front.
after all joint has manual homig, dispaly change not normal homing dot come H letter.

i test MDI site some g-code run X,Y but not Z one time try same code second time not move..
wery hard test and go back comment to forum, my internet pc have 2 floor at house, need go 1 floor out house run arund house to backyard were have workshop and cnc and test , and then run back to house and 2 floor to my pc. not have internet at workshop. hard.
upstairs use internet and usb memory move files to down backyard workshop pc and add files to linuxcnc.

ah, im not can make this working if use MDI add G0X50F100 etc, move ok but all axis same problem if use GoX-40F100 any axis not move minus to back .
i not understand this any now. or move manual continue, selected axis X or Y or Z move plus + side but NOT minus - side newer. if try minus come sometime errors lot. exceed joint 1 and 2 and somethink i not know what errors mean.
and last night has workshop i delete machine my name config conf file not know were file go i not found. maybe all need do again new at config wizard now. but i not understand have this right table size and limit system. why linuxcnc not have option can select XYZ or XYYZ or XXYZ not have but have only shit XY or XYZ foam or lathe or custom.
