What happens if you change your encoder scale from: ENCODER_SCALE = -5000 to: ENCODER_SCALE = 5000
If this makes it behave better (but maybe backwards) you may want to switch the wiring of your encoder feed back to switch direction. ----- Original Message ----- From: r...@superiorroll.com To: "Emc Users" <emc-users@lists.sourceforge.net> Sent: Tuesday, November 24, 2015 2:23:54 PM Subject: [Emc-users] Trouble with 4th axis Hello guys, working on my 4th axis, and I am starting to feel quite lost, I was figuring that this would be the easier of all the other work I have done with this stuff, due to working with a brand spanking new servo and drive, but has turned into a nightmare for me. I have the axis running, I can control it with my hand-wheel MPG, it homes ( if that's what you want to call it ) and and after tuning the servo to the drive, I don't think there would be any tuning involved on the linuxcnc side, if the Following Error was even understandable. For starters, when I start up linuxcnc, and I press the "home all" button, the rotary goes through the motions of the following homing sequence in the link using inserted values on the image http://postimg.org/image/yxzcdwldx/ And does set the "0" position, but then it takes off at max velocity, and stops at some random value ( 1255, 159, 1800 ) always in the positive direction, and not repeatable, and then says that it is homed ( No clue ). As for the following error, pretty much it is telling me that whatever the DRO is displaying, it is telling me that the following error is the inverse of the display, if it says that I am at 259.354 degrees, I will have a following error of -259.354. I tried to make a few G01 commands, and it does begin movement if I give it a position to go to, but it does not stop at the dimension programmed, and in the DTG column, it is just displaying whatever the "actual" position is not a distance to go. Here are my config details from my hal file and my ini, http://pastebin.com/WT8fMkvY Any thoughts of help will be greatly appreciated -- Thanks Rick Lair Superior Roll & Turning LLC 399 East Center Street Petersburg MI, 49270 PH: 734-279-1831 FAX: 734-279-1166 www.superiorroll.com ------------------------------------------------------------------------------ Go from Idea to Many App Stores Faster with Intel(R) XDK Give your users amazing mobile app experiences with Intel(R) XDK.
