This didn't make any difference. What does fix it is disabling BACKLASH.
And that led me to the STEPGEN_MAXACCEL set too low. Initial testing didn't
have backlash enabled so the 25% increase in STEPGEN_MAXACCEL was more than
adequate. But with backlash enabled it broke. Should really follow the
comments in there. Turns out on the actual machine with the parallel port I
did have STEPGEN_MAXACCEL set to just over 100% larger.
Ahh yes if you have backlash correction enabled you should set the stepgen
maxaxxel to say 2.5 the machine limit
originally created by pncconfig. Should not
setp hm2_7i92.0.stepgen.00.control-type 1
be control-type 0?
No, needs to be 1
So what does it need to be for the spindle then?
Also 1 since you are setting the steprate from the spindle speed
The tutorial suggests stepgen is type 0 for step/dir and "ctrl_type" type v
for velocity.
I haven't found the details on "control-type" in a document yet.
hm2_7i92.0.stepgen.05.control-type
Perhaps I overlooked it somewhere?
man hostmot2, stepgen section
loadrt stepgen step_type=0,0 ctrl_type=v,v
