Re: [Emc-users] How to unlock a linear axis
Hi, Thankyou for your test, you have save me much time, but I'm a little disappointed becouse I think that I'm stupid becouse I can't find a way to do the job ... is it impossible that in all the time that linuxcnc exist no one had my same problem. Well, a way illustrated from Kirk Wallace seems good but I'm not sure on how implement the trik, I don't know how to force the commanded position from the motion part to be at a fixed point even if it have a jog or G command, I have made some test with the axis.N.motor-pos-fb but the tracking error remain. I hope in a miracleor someone much clever than me. 2012/8/15 sam sokolik sa...@empirescreen.com I just played with master. It looks like if you add LOCKING_INDEXER = 1 to a linear axis - it doesn't create the pins. (but does make it so you cannot jog it) So it 'sort of' works. :).

If I understand correctly, then if joint with LOCKING_INDEXER = 1 is being moved, then all the other joints have to stand still, so there is no interpolation between this particular joint and the other joints. In that case You can easily set that joint to be rotary joint. It does not matter that it actually is linear joint. If all the scale values, angular velocities and accelerations etc are set correctly, then it will move You to right position at right speed and acceleration. And with rotary joint You will have all the required pins created and You will not need to hack feedback position or ferror parameters. -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Emc-users] How to unlock a linear axis
Guys let's look at this a little bit You want to keep the slide from attempting to move while the brake is engaged. Is that the desired machine action? If you do not physically mount a switch to the brake how does the control know the brake is engaged or not? Even if you find a software solution to the control problem the control will still not 'KNOW' if the brake is engaged or not. With a switch mounted on the brake the speed of the engage/disengage cycle is not important to the machine/control loop. just my 2 cents thanks Stuart -- dos centavos -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

What do you think of the behavior of the locking-indexer? Is possible to reproduce something like this for linear axis to? Andrea I have no experience with this but, my thinking is that one should read the locked axis position and make that the commanded position, then when the the axis is unlocked, with a small delay for the brake to become fully unlocked, the axis will not move. Then the new position can be commanded without worrying about the brake being on. Thinking a little more, it seems the problem is in the sequence of g-code commands. When the axis stops, the commanded and actual position should match, or at least after a short time. The brake can be applied. Then when a new position is needed, release the brake, wait a short time, then command the new position. Or, I could be completely wrong. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Emc-users] How to unlock a linear axis
Hi, thanks to all, well I have made a test, I have add LOCKING_INDEXER = 1 in the linear axis and then I had run linuxcnc, no error at startup and when I have tried to jog the axis an error Can't jog a locking axis..sounds good...after this I have modified the hm2-servo.hal to add the line to controll the behavior but at startup linuxcnc give me an error Pin axis.0.is-unlocked doesn't exist 5990, I run the 2.6.0 pre0-3148 version of linuxcnc because I have read somewhere that only the new 2.6 will have this feature. Why I get this error? How you have made your code? Thanks. 2012/8/14 sam sokolik sa...@empirescreen.com To add - It doesn't seem like it cares if it is linear or not...

Re: [Emc-users] How to unlock a linear axis
I would first check to make sure that your pneumatics are working correctly. I have found on machines I worked on that the silencer, on the exhaust port was partially plugged up, and caused the cylinder to release slowly. A new silencer corrected the issue. But I do like the suggestions from the others on using direct feedback to notify the controller that the cylinder is in the released position before motion can start. --J.

Re: [Emc-users] How to unlock a linear axis
I just played with master. It looks like if you add LOCKING_INDEXER = 1 to a linear axis - it doesn't create the pins. (but does make it so you cannot jog it) So it 'sort of' works. :). It probably should do all or nothing. sam On 08/14/2012 03:46 PM, Andrea Buono wrote: Yes it is, 2012/8/14 sam sokolik sa...@empirescreen.com Was it axis 0 that you added the LOCKING_INDEXER = 1 to*? sam * On 8/14/2012 3:31 PM, Andrea Buono wrote: Hi, thanks to all, well I have made a test, I have add LOCKING_INDEXER = 1 in the linear axis and then I had run linuxcnc, no error at startup and when I have tried to jog the axis an error Can't jog a locking axis..sounds good...after this I have modified the hm2-servo.hal to add the line to controll the behavior but at startup linuxcnc give me an error Pin axis.0.is-unlocked doesn't exist 5990, I run the 2.6.0 pre0-3148 version of linuxcnc because I have read somewhere that only the new 2.6 will have this feature.
