U axis configuration

Hi Rick I changed it in SCALE = in INI but now you ask I think I see a problem, I'm working back from measurement instead forward from drive?

I looked at Pico, couldn't find anything on the others, not that I looked real hard @ + - $250.00, certainly something to look at down the line. But I can run the machine on Mac3 at 48000 mm a min on a slaved XA axis which is not too shabby so I am obviously doing something wrong.

Just lost the lot again some how I get logged out when submitting something and other times I log out only to stay logged in with no log out button.

Sorry that was 22000 mm/min which is still pretty fast about 330mm/sec. But that was only jogging and with an 80mm run up to top velocity. I have never cut a full substantial program in Mac3, there is always some Windows application wanting attention hence EMC2. Well while drafting the last reply I stumbled on my foolishness I changed the Scale on the INI but not dirhold and dirsetup base periods in HAL so that makes th velocity even worse. If you need to kill an EMC2 machine I'm your man.

So thanks for that sometimes one just needs to talk to someone to clear your mind.

Thanks also for the link if once I have this sorted and I find I need a little more smoothing i shall certainly look into it in further detail.

Cheers Paul

No wrong again wrong assumption.

In Joint mode I can run any axis X Y Z A at 12000mm/min or 200mm/sec which is more than satisfactory. But as soon as I go into World mode I get immediate following errors.

Just discovered something else, when jogging X in joint no problem but A the linked in world axis moves much slower but I cant jog much more than 100 mm at a time in joint without straining the rig. I have X and A on same scale ( 6mm/rev) and Y and Z on a different scale (1.75mm/rev) and it seems A is picking up scale from Z in World mode rather than its own scale hence the following error. What do you think any ideas or am I way out again.

Those are my files Hal and INI I tried X2 in place of A in Hal and INI TRAJ coordinates and joint mode AXIS GUI lost joint 3 but jogging joint 0 still gave a joint 0 and 3 following error.

Thanks again for all the help Andy, I know I've been a pain.

cheers paul

Sorry I forgot I am using EMC2 version 2.4.6
