Trying to Configure Dual Y Axis was created by Routerworks
I think I am close but an getting one error and can't figure it out. I attached a copy of the INI, HAL and error report file.
I ran all the timing and stepping scales on a single Y axis program and everything is calibrated and working fine. If I could simply add this additional motor to the Y axis that would be great. I can add parameters for homing later.
Would greatly appreciate any help.
Thanks in advance

All you need to do to set up a dual axis is to add HOME_SEQUENCE= to each of your joints in the ini file
This sets the order of homing. Joint axes are tied together with a negative value. Usually you will home the Z first to raise it out of the road. Note you have to consider homing and add home switches now as it's required for the joint axes.
Joint 0 HOME_SEQUENCE=1
Joint 1 HOME_SEQUENCE=-2
Joint 2 HOME_SEQUENCE=-2
Joint 3 HOME_SEQUENCE=0

Humm, No... Only INI and HAL are attached... no error report file...... I attached a copy of the INI, HAL and error report file...

Thanks a lot. This looks encouraging. I will make the changes and give it a try.
I didn't realize the homing was required
Many thanks

Had to change format.

Nope, no report.

Do you have it now?

From your hal file:
net ystep => parport.0.pin-04-out
then
net y0pos-cmd joint.1.motor-pos-cmd => stepgen.1.position-cmd
net y0pos-fb stepgen.1.position-fb => joint.1.motor-pos-fb
net y0step <= stepgen.1.step
net y0dir <= stepgen.1.dir
net y0enable joint.1.amp-enable-out => stepgen.1.enable
That will not work, ystep requires ypos, ystep, ydir, yenable, etc, not y0pos
this is all over the hal file, so to many things to fix.

Lets go back, you have a parallel port, so limited IO, do you want:
-to have limit switches on all axis/joints?
-do you need to square the gantry or is it stiff enough to stay trammed?
-do you want to have both motors/drives for Y axis run at the same time, even when jogging and before homing the machine?
net ystep => parport.0.pin-04-out
then
net y0pos-cmd joint.1.motor-pos-cmd => stepgen.1.position-cmd
net y0pos-fb stepgen.1.position-fb => joint.1.motor-pos-fb
net y0step <= stepgen.1.step
net y0dir <= stepgen.1.dir
net y0enable joint.1.amp-enable-out => stepgen.1.enable
That will not work, ystep requires ypos, ystep, ydir, yenable, etc, not y0pos

From the hal file:
setp parport.0.pin-01-out-invert 1
net estop-out => parport.0.pin-01-out
net xstep => parport.0.pin-02-out
setp parport.0.pin-02-out-reset 1
net xdir => parport.0.pin-03-out
net ystep => parport.0.pin-04-out
setp parport.0.pin-04-out-reset 1
net ydir => parport.0.pin-05-out
net zstep => parport.0.pin-06-out
setp parport.0.pin-06-out-reset 1
net zdir => parport.0.pin-07-out
net ystep => parport.0.pin-08-out
setp parport.0.pin-08-out-reset 1
net ydir => parport.0.pin-09-out
net spindle-cw => parport.0.pin-14-out
net spindle-pwm => parport.0.pin-16-out
net xenable => parport.0.pin-17-ou
So, ystep and ydir is repeated:
ystep goes to pins 04 and 08
ydir goes to pins 05 and 09
BUT no 'y0' or 'y1'
Then after that you started using y0step and y1step
net y0step <= stepgen.1.step
net y0dir <= stepgen.1.dirAND
net y1step <= stepgen.2.step
net y1dir <= stepgen.2.dir...
setp parport.0.pin-01-out-invert 1
net estop-out => parport.0.pin-01-out
net xstep => parport.0.pin-02-out
setp parport.0.pin-02-out-reset 1
net xdir => parport.0.pin-03-out
net ystep => parport.0.pin-04-out
setp parport.0.pin-04-out-reset 1
net ydir => parport.0.pin-05-out
net zstep => parport.0.pin-06-out
setp parport.0.pin-06-out-reset 1
net zdir => parport.0.pin-07-out
net ystep => parport.0.pin-08-out
setp parport.0.pin-08-out-reset 1
net ydir => parport.0.pin-09-out
net spindle-cw => parport.0.pin-14-out
net spindle-pwm => parport.0.pin-16-out
net xenable => parport.0.pin-17-ou

ystep goes to pins 04 and 08
ydir goes to pins 05 and 09

net y0step <= stepgen.1.step
net y0dir <= stepgen.1.dirAND
net y1step <= stepgen.2.step
net y1dir <= stepgen.2.dir...
