Yes, I have lot of oscillations problems with the screws. Now working on this. But on the video I'm close to the maximum speed of the steppers. They can't go over 3000rpm, because the torque is very low when I go faster, and I lost lots of steps. On the video the speed is approx. 80% of max speed.

I agree there would not be much to be gained by running the parports in ECP mode. Mesa is planning to use DMA not for the parport boards, but for the PCI and PCI-Express boards. PCI I/O latency is dominated by bus setup and negotiation, this is especially bad when several busses are chained, as they are with the 3x20.

Is that kind of how it works? No, not at all. Either using the Mesa board or the Pico Systems PWM controller board, the CPU sends a PWM width command once every millisecond, and the PWM generator sends the required pulse width (with much greater accuracy and resolution) to the drive. The later Pico Systems PWM controllers set pulse width in 25 ns increments, so at 50 KHz frequency you get 1 part in 800 resolution or 0.125 %. You could possibly get about 10 us resolution from the parallel port directly, at 50 KHz that would give you a resolution of 50% which would never work for a servo drive.

And, you pay for the necessary intelligence in the drive. Is it possible to run a brushed DC servo with just a simple H-Bridge controlled directly by the PWM output and a direction signal? Yes, but you have to be very careful about how you deal with overcurrent and current limit situations. Also, the motor inductance and the fast switching of the transistors can produce a LOT of electrical noise. That's why my drives (Pico Systems) have output filters, to save you the hassles of noise getting into your encoders.

I found some laptop assembly screws that just happened to be the right length. Mariss seems to love these encoders over the cheap us-digital ones for his step/dir servo drives I got one of these a few months ago and the holes were NOT tapped at all, just dimples, really in the casting. So, I don't know if these holes are supposed to be tapped or not.

If so yes. /usr/share/doc/emc2/examples/sample-configs/hm2-stepper/7i43-small.ini Have you tried running emc and selecting the hm2-stepper/7i43-big config from the list? I didnt see any of the hostmot2 output in the dmesg log you included. Like Seb said, if you go to a terminal window and run emc return, you should get a pop up screen which allows you to select a number of configurations. The 7i43 is there under hm2. Linux takes some getting used to for us old Dos/Winders users... Hang in there - it is worth the effort. :-) Dave -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] GUI for hole-probe.ngc
Ohh, I did know about it before. Thank you, I will see There is Gwiz, the wizard framework, http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?GWiz_-_A_Gcode_Wizard_Framework It's pretty easy to copy and paste an existing wizard to extend it. -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
