I'm a JA3 user, and I can only use that with my machine. unfortunately there's still a bad bug on limits, as long as joints limits rules over machine limits.

[Emc-users] goes into joint-mode after MDI.
I, i have a very annoying problem. say i'm into world mode and jogging.. (f3, manual mode) ok. then i write a movement into MDI. (f5, mdi mode) ok. then i press again f3 and go back to the manual mode, but... it become joint mode, instead of world mode! i find this very annoying, because if you have a weird kinematics, when you go to f3 and think you're again into world mode if you move something then the kinematics maths become wrong, and you have to set everything into home position again (and in my case it's a pain..sometime. Is there a way to say to axis, that after MDI if i press f3 it should give me again world mode? thanks, Davide. -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

I could speed-up the base thread to 1ns having just a little slowing of the system (i'll go to 12000ns..) and the charge pump is still working ok. it means a signal clock of 50kHz.. the solution of the freq gen is good and easy, i think.

[Emc-users] Add New Thread
Hi, finally i'm trying to get my new Keling motors and drivers work, together with a C35 BoB from cnc4pc. I wanted to use the charge-pump function (that, if i understood, act as a watchdog), so i need a signal coming from LinuxCNC every 12,5 kHz, as written in the manual. On our wiki i've found this: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?About_Charge_Pumps well, i made it work adding the function to the base-thread, and setting that to 4ns , which means 12,5kHz as requested. (read the link for that value to come out) In the same link is written also that one can add a new thread, if the base thread period is different from what needed (mine was 49k and something..). So do you think is better to add a new thread dedicated to the SCHP (charge-pump), or to lower the base-thread period and work with that? If a new thread is the option, how can i add a new one? i've tried with the real component 'threads', but it doesn't work (maybe my fault). if it helps, my Tested Base Period doesn't go over 4000ns.

Allora, conta che cmq io non sono un esperto, ma se adesso il file di cinematica lo cerca li penso che hai lanciato emc2 normale. Può essere?

Note that the same setup works on my machine. Here it is under Virtualbox, and
i want to know why it doesn't run.
Tried the same setup, but without gladevcp and hidcomp and it runs.
if i try to run my setup with hidcomp, but without gladevcp i have two cases:
-it's ok if it's the first thing i do after turning on the machine.
-it doesn't run if i try first the normal setup(complete) giving error, then i
try hidcomp, without gladevcp but it doesn't work

OK. then i tryed to compile my kins module, and copied the file .ko in the rtlib directory, but when i run my config it asks for a .so kin module. i don't know how to create that, can you help me? i've read 'man comp', and it says to use --compile, but i can't. any suggestion? thanks, Davide. -- Write once.

Another thing that comes to my mind is that as i run the setup, the spinbutton is set to 0, and maybe it causes some 'division by zero' error. i want to try to setup the spinbutton to start with a value, but I can't. it seems that the Value field, inside Adjustment Properties in the glade wysiwyg doesn't affect the starting value. any help?

[Emc-users] or4 ?
Hi all, i need to compare 4 inputs into hal (a limit value on each of 4 motors) and if one of them is true the output will be true. (it is a tetrapod, so only one motor-limit at a time can be true, fisically.) The fastest way in my mind is to use 3 or2 components, so i compare two or2 outputs as the third or2 inputs, and i know that will work, but is there some way i can solve the same logic with less components? p.s.

[Emc-users] Hal question
Hi. What i need to do is to enable joystick jog only when button1 is pressed,to avoid accidental movements. I think to do it with an if statement, but don't know how to implement into hal commands. I think i cannot use and2, because button is a bit, while value from the stick is a float. The only way that comes to my mind is to use mult2, using as inputs the float value from the stick, multiplied by 0 or 1 if the button is pressed or not. Can you tell me what's the right way to do it? Thanks, Davide. -- Learn Windows Azure Live! Tuesday, Dec 13, 2011 Microsoft is holding a special Learn Windows Azure training event for developers.

One thing that i really find usefull can be, when programming g-codes, to have a letter (i know they are all used..) to control acceleration ratio. so that for every single movement i could set acceleration. and is at the programmer's knowledge to decide where it can be useful a rapid acceleration ratio, or a slow one. for example a pick and place flexible machine, if it picks heavy things, maybe will be good to slow down the accelerations. Personally i use EMC2 for 'artistic' purpose, i'll find very useful this possibility! again, you can imagine an exapod used for something similar to a car simulation, and you'll need variable accelerations. i think it will simply make EMC2 'more comlete'. thanks, dab. -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

[Emc-users] more powerful nema23 need.
Ciao a tutti. i've built steel structures for nema23 stepper motor reelers (don't know if the word is exact, intended a drum to roll a wire on..). i've 4 of these motors, to setup an inverted tetrapod. (for those who followed me, i used this to make a volleyball fly in the air...just artistic purpose.) Now i would like to improve a little this system power, so i'm going to ask you an help, for i know your knowledge is huge. so, the nema23 i'm using are (on paper):rated current 2,8A , 4 wire and have a holding torque of 12,6 kgf/cm (175 oz/in). the calculated holding torque after the gear demult. and the drum diameter is 5,4 kg. in fact each motor has a gear set which doubles the power, and the drum is 5 cm radius. so 12,6 * 2 / 5. in the real world (with friction ect..) i've proven that when moving the max weight i can apply on each motor is around 1,3 kg. i would like to know if you know about nema23 motors (either stepper or servo) with more (kind of double..) torque. I'm asking about nema23, because in this way i don't need to change the structure, just need to exchange motors.. any idea? By the way, we did another show with this motors, in which we made a magic ball and a microphone fly! as soon as possible i'll post videos. ciao!! -- Beautiful is writing same markup.

(since i need 10mt long cables to motors, i'm going to use a 4wires-0.5mm plus shield cable, with shield wired on ground of driver board, and 4-pins-XLR connectors.) then on mondey morning i'm going to setup the final show. it's the opening show of italian volleyball cup. i've 4 girls linked (hanged) at 15mt height, and they should 'play' volleyball with the EMC2-controlled ball!! all hanged on a GRU (i don't know the name,maybe mobile-crane..) that's my job.. so i can wish in the new version of emc2 to solve a better difference from JOINTS and WORLD AXES. for example i think (like is said in the docs) that naming joints XYZABCUVW is not correct. maybe the right way can be joints 1-9 and one can say wether they are parallel to XYZ or spin around XYZ, or if they have their own kinematics. thanks again. -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Want to thank everybody for interest. than, as Brian suggest is interesting, but i really cannot know the formulas of the arcs i'm drawing. also writing by hand the acceleration like g1 f100, g1 f150, g1 f220, g1 f400 you know, the show is like 5 minutes of a volleyball doing maybe 80 arcs in the air!! cannot write all by hand!! so, i think i'm going to work with the little segments way, increasing in lenght as i want the speed to accelerate..maybe is the fastest way of writing, cause 3dstudio will work for me! basically, there are two reasons why i need this now: 1) immagine the ball flyng at 30mt/min in one direction, and then suddenly the direction become opposite. the ball bounces for the 'impact' (sorry for my poor english..) and the stepper motors loose some step. 2) tryed to use in the .ini file a slow acceleration, but using that it return me error when i jog in world mode. i realized that the slower is acceleration, the slower is the jog speed that i can reach without errors in world mode. any other suggestions, especially for the point 2? thanks again, davide. -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

(maybe this night..) but i was thinking too, of using two batteries in series (24V) to power up the driver card directly, and to use only one inverter on one of the two batteries for the notebook. what do you think? is it going to work better for sure? thanks, davide. -- Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing http://p.sf.net/sfu/novell-sfdev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
