[Emc-users] Encoders on 7i48
Hello, gentlemen! I would like to ask, if someone can suggest me, why I do not see encoders in HAL Config. I have pasted a screenshot here: http://www.cutting.lv/fileadmin/user_upload/emc2.png I have Mesa 7i48 card, attached to 7i43. The config line tells hm2 driver to load 6 pwm gens, 6 encoders and 3 stepgens. I am using this customized firmware, that was kindly provided by Peter Wallace: http://www.cutting.lv/fileadmin/user_upload/SVST6_6.BIT http://www.cutting.lv/fileadmin/user_upload/SVST6_6.PIN As the screenshot shows, there are 6 pwm gens, 3 stepgens, but no encoders on 7i43 card. What am I missing here? Can I ask other 7i48 card owners to share their experience? Note: that one encoder is HAL module for NHC (nozzle height control) purposes. Thanks!

Re: [Emc-users] hola gente si pueden necesito ayuda
hola cristian Aqui habitualmente se habla ingles. Para tu problema, tienes que conocer el nombre de pasos de tus motores (si utilizas motores paso a paso), y el nombre de division de paso de la electronica de los motores. Pour ejemplo, con motores de 200 pasos, y una electronica que hace 1/4 de paso, tienes emc tiene que enviar ordenes para hacer 800 pasos para que el motor hace una revolucion completa. para tu eje X, con el diametro de la polea situada sobre el eje del motor, puedes determinar la distancia que la cinta pasara para cada paso del motor, calculando la circunferancia de la polea / 800. por ejemplo si la polea tiene un diametro de 20mm, la circunferancia mide 20x3,14 = 62,8mm, es decir que para une torno completo del motor, la cinta va a viajar de 62,8mm. Y por solo un paso del motor, va a viajar de 62,8/800=0,0785mm. para los otros ejes Y y Z, con el mismo ejemplo de motores de 200 pasos y 1/4 paso para la electronica, si el tornillo tiene un paso de 1mm, es decir que para un torno completo del motor, el eje va a viajar de 1mm. Es facil determinar el viaje para un paso : 1mm/800 = 0,00125mm.

For type 2 I get -9.98V on X1 and X2 outputs right after enabling EMC, Y is 0V. Pressing F2 to disable returns outputs to 0V. Pressing it repeatedly will repeatedly turn motors on and off. I would like to ask, if someone can share sample HAL config for 7i48 card. Currently I cannot figure out, how to set up pwm generators. I am getting either + or - 9.99V on one channel, only -9.99V on second channel and nothing on third channel. Any ideas, where should I look?

[Emc-users] VIM syntax for comp source
Does anyone have VIM syntax highlighting for editing comp hal component source code. Obviously C-language syntax highlighting goes a long way for this, but VIM highlighting seems to get confused with some of the comp specifics, especially the man-page documentation features. Thanks.

[Emc-users] Need Latency Help w/IBM ThinkCentre PC
Gentlemen, I purchased a refurbished IBM ThinkCentre PC to use as a controller for a V90 Fireball CNC router. I'm currently trying to get the PC tuned up and ready for the arrival of the machine. Everything is going well with the Linux/EMC2 install. The problem is that the latency Max Jitter will start out right at 5000 to 6500-ish then jump to 120,000. If I reset the statistics, it will stay low for (usually) exactly 30 seconds then jump up again. I read the Wiki and it suggests an SMI problem. I've tried everything else to no avail. I've installed an ATI S9250 video card, turned off everything in the BIOS, and added additional RAM. The BIOS won't let me disable the on board video, only select which one is used at boot-up. I am also having a hard time finding the correct ATI driver, there seems to be alot of them listed in the Ubuntu repository. After reading the WIki, I'm thinking I'll need some guidance if I have to shut off the SMI. I don't understand if SMI is shut off with a hardware switch, or thru software. I couldn't find any reference in the BIOS. I've read the warnings and like Sir Robin, I am willing to face the danger. Here are the specs: IBM ThinkCentre - Intel i848/i865 Chipset Pentium 4, 2.7 GHz 1 GB RAM ATI S9250 Video Card (256M RAM) Wireless-G Network Card Thanks in advance for any assistance!!
