[Emc-users] Parallel ports
Hi, I have just installed a new twin parallel port card in one of my linux boxes to start playing with servos. Can someone please remind me where I can look in Ubuntu 8.04 to check that the ports are working and what their addresses are? Thanks. -- Best wishes, Ian Ian W.

[Emc-users] ER Capable spindle replacement for Kress.
Does anyone know which ER capable spindle/motor is the best cost effective replacement for the Kress as shipped with Isel CNC? I want to move away from the restrictions the custom Kress collets creates and nee to replace it with an ER capable spindle/motor. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
[Emc-users] touch probing for tool length calibration
Hi, I've got access to a 3-axis-mill that uses replacable milling motors. On disadvantage of them is that the used cutters are hand-placed thus vary in length. Now I was wondering - is there any chance of using the gcode for probing and dynamic tool length compensation to enter a calibration-routine after the tool has been switched? We would of course need a inverted touch probe thingy - e.g. capacitive sensor plate, or something like that - to move the cutter to get feedback over the tool length. This most probably would also involve using two coordinate systems, on for the piece and one for the length probing. Any suggestions?

Re: [Emc-users] Tune up- HAL Oscilloscope.
Hi I have another pic http://www.conceptmachinery.com/Sh11.jpg On the graph X pos-cmd commanded position. Xpos-fb Xpos-cmd commanded position and it parallel to Xpos-fb. That what is should be? X output begins ok but ends wrong. Think X output should looks like trapeze. What need to change to make second part of X output looks like first? My current P 230, I 1.8, D0. Also pid.0.error should be similar graph to X output, is this right. When X output become flat so should be pid.0.error become flat. But in my case it is not. What should I change here?

Re: [Emc-users] Tune up- HAL Oscilloscope.
Xoutput is again saturating at +1. Did you check that the +1 level is OK, and it shouldn't go to +10 ? If +1 is the correct limit then you are simply asking for too much speed during the cruise-phase. Lower MAXVEL until Xouptut stays below +1 during the cruise-phase (maybe at 0.7 - 0.8 or so...)

[Emc-users] Success driving Panasonic Minas S (MUMS) brushless motors
Please excuse a short commercial plug Dave Engvall gave me a Panasonic brushless motor at the CNC Workshop to see if I could figure out how to run it. It took me a LONG time to get around to figure it out, but I have finally got it! It has a serial output that contains the commutation signals, so I have to add a little decoder for that signal. Otherwise, i have gotten it to work with my Universal PWM Controller and brushless PWM Servo amp. It works quite smoothly, better than a number of other brushless motors I've tried. The motor I have is a Panasonic MUMS042A1A, but I would assume all the motors in that Minas S series would work as well.

Otherwise, i have gotten it to work with my Universal PWM Controller and brushless PWM Servo amp. It works quite smoothly, better than a number of other brushless motors I've tried. The motor I have is a Panasonic MUMS042A1A, but I would assume all the motors in that Minas S series would work as well.

Use only P ( on the drive) and lower P to the point where the drive needs between 9 10 volts to go max velocity. Set other parameters to zero and then start tuning the P and FF1 in emc, then go on from there. If that doesn't work then have a conversation with Servo Dynamics; I've always found them to be very helpful.

It is SD-94 8 amp constant from servo dynamic http://www.servodynamics.com/sd94p_servodrive.html It may be a setting in the .ini file, limiting EMC to an output of 1.0 output units, which may or may not scale to 100% output to your drive. Default velocity is 1.0 user units/second.. That could be 60 mm/min or 60 Inch/min, depending on the setting of LINEAR_UNITS in your [TRAJ] section. Also, settings in the Servo Dynamics drive could limit the maximum velocity.

tomp wrote: you mention a 'dumb' driver anything you know of for AC drives? i've done this with lots of copley's but those were dc brushed amps I have my $150 PWM brushless servo amps, which can be driven by my universal PWM controller. The amp just delivers supply voltage x the PWM duty cycle to the motor, unless current reaches the limit value. So, it is a REALLY dumb amp, no torque control loop, no sinusoidal drive, no encoder input. it does need commutation signals. I've driven Giddings Lewis, Pittman, Servo Dynamics and Panasonic motors with excellent results. I've tried a few others with mixed results, mostly a lot of motor vibration, due to the six-step drive. See http://pico-systems.com/acservo.html for more info.

So, that was quite easy to decipher and design a simple gizmo to convert back to the standard UVW commutation signals. These motors have traditional ABZ position encoders. On the proprietary Yaskawa motors made for their own drives, the encoder only has 3 channels, and encodes position AND commutation all in those. A and B are normal, but the C channel flips the phase relationship between it and the other two to give commutation and index pulse encoding. I got the general idea, but I can't say I understand how it works.
