Greetings;
I just took a few minutes to play with it, using the same configs from the
2.3.6? install I had before, and two things are glaringly obvious.
1, I either need to throw about 10 times the cpu at 2.4.3 than 2.3.6
needed, or something is pretty badly miss-configured.
Having it run the logo code, cutting air, the backplot only gets updated
about once a second, ditto for the code display in the bottom of the
screen, skipping from having line 317 highlighted, to 328 on the next
screen update. Hitting the stop button takes about 2 seconds to recognize
the mouse click, and after the machine is stopped, I hit F5 and entered
g0z0y0x0. It moved back alright, but took about a second after I hit enter
to start the move. The backplot showed two more snapshots of the motion
after the motors had stopped at 0,0,0, finally arriving at 0,0,0 on the
third screen update after the motors stopped..
This is an XP1400 athlon running at 1.6 ghz, half a gig of ram, using the
radeon (spit) driver on an ATI 9200SE card.
The BASE_PERIOD etc:
[EMCMOT]
EMCMOT = motmod
COMM_TIMEOUT = 1.0
COMM_WAIT = 0.010
BASE_PERIOD = 58000
SERVO_PERIOD = 1000000
This is quite conservative IMO as 2.3.6 could, with less lag than I'm
seeing now, run down to the 28000 range, but 58000 still allows more steps
than my motors can handle.
Is there that much diff in the expected abilities between these two
versions?
If its going to take more iron to run this, how about a suggestion for a
newer motherboard, video card etc that can do all this in real time?
Thanks guys.
