I suspect that you are right. For the sake of time running out I
just slaved the X stepgen in the bit file. I am using a simple
trivkins with no slave axis defined. The only issue now is that
the DIR signal on the slave has to be inverted somehow. Is there
a way to NOT the pin in the bit definition?
setp hm2_7i92.0.stepgen.xx.direction.invert_output true
I know that one but I am brutalizing the bit file by putting the
stepgen 0 on two allocations. I would like to invert the
StepGenDirPin in the bit file before I compile. If possible.
That seem;a a bit crazy to me and prevents proper gantry homing for
example
why not just fix the hal file?
Agreed but I am now desperate to get things working. I have no
control over that section of the hal file. The slave axis looks
identical to the master axis. I cannot see anything that I can do to
fix it.
I have a thought about the issue. I set kinstype from BOTH to 1 in
order to combine the jog buttons and the machine is not forced to
home before jogging. The machine only has one home switch on every
axis. SO maybe the rules are not met. I don't know.
This is a drop in upgrade so I am not allowed to change any of the
wiring. The machine ran on Mach3 previously.
I would check if the joint for X2 axis is actually connected
I suspect the kinmatics it not correct
Note if you want to duplicate the x axis joint on another stepgen
you just run both stepgens/PIDs from the same joint commanded position
position command, basically only 2 hal lines need to be changed,
the X2 joint PIDs commanded and feedback positions
It is definitely not connected if the kinstype =1 is set. No position
command received. I just checked. So your suggestion will solve the
problem I am sure. Then inverting the slave is also no problem
I will reprogram the 7i92 with 5A_BOBx2D tomorrow and redo the config
with your suggestion.
Thank you very much for all your help. I am sure you must get frustrated
with clever dicks like me. I somehow always manage to get the most
impossible damn jobs.
