Re: [Emc-users] bldc hal file example?
2012/6/22 Ralph Stirling ralph.stirl...@wallawalla.edu I have my prototype linear motor assembled and ready to test tomorrow. I'm trying to figure out how to connect everything in hal, and seem to be missing some pieces of the puzzle. I want to use a 7I43 to generate the PWM signals with the bldc component. I'd like to run open loop for my initial testing, and add an Austria Microsystems magnet linear encoder later for closed loop. Andy or Peter (or anybody else), would you have an example ini and hal file for generating 3-phase waveforms open loop with a 7I43? Do I need a different firmware for 3-phase, or can the standard SVST4_12 in conjunction with the bldc component do the job? Hi Ralph, Later today l can share my config for 7i43+7i39 linear motors.

As Andy has already pointed out, you could setp the input pin of the OR gate: halcmd setp or2.0.in1 1; You could also retain the readability benefits of the named signal by using the sets command, which lets you set a signal instead of a pin: halcmd sets pause-console 1; -- John Kasunich jmkasun...@fastmail.fm Thanks both for your answers. I am quite sure I tried halcmd setp or2.0.in1 1; and it didn't work (it failed with a message pin already in use or something like this). Wasn't aware of the existence of the sets command, great! I will get a try again in a couple of hours and let you know. Xavier Oh, right - it won't let you set the pin because there is a signal connected to it. If you delete the line net pause-console or2.0.in1 then the pin would be free, and setp would work. But personally I would keep the signal and use sets. That way you have a nice readable signal name when you are studying the HAL file five years from now. You know what ? You are 100% right here ! I have tested the 2 solutions, and yes, both work. To sum-up the two solutions: 1) *** using setp *** - custom.hal contains: loadrt or2 count=1 addf or2.0 servo-thread net programPause = halui.program.pause net pause-joystick or2.0.in0 = input.0.btn-thumb net programPause = or2.0.out - and my emc_pause script is modified as follow (we address directly the second input of the OR gate): #!/bin/sh halcmd setp or2.0.in1 1; sleep 0.1 halcmd setp or2.0.in1 0; sleep 1 halcmd setp halui.spindle.stop 1; sleep 0.1 halcmd setp halui.spindle.stop 0; halcmd setp halui.flood.off 1; sleep 0.1 halcmd setp halui.flood.off 0; echo Machine paused. 2) *** better solution: use sets (set signal) *** - custom.hal contains: loadrt or2 count=1 addf or2.0 servo-thread net programPause = halui.program.pause net pause-joystick or2.0.in0 = input.0.btn-thumb net pause-console or2.0.in1 net programPause = or2.0.out - and the beginning of my emc_pause script is modified as follow (this time we address the signal that is connected to one of the input of the OR gate): #!/bin/sh halcmd sets pause-console 1; sleep 0.1 halcmd sets pause-console 0; sleep 1 ... Obviously, I did the same for the emc_resume script / button. The only difference is that we declare two OR gates (loadrt or2 count=2) and the second one is addressed with the name or2.1. Note for those who are looking for more info: the html documentation doesn't contain all the commands (eg I think that sets is missing), so take a look at the man page of halcmd (man halcmd).

(no linear bearings) That platform (video) looks really far along. One of the mechanisms IBM used in this arm to maintain constant direction on the front facing appendage is just link it with a belt to the theta 1 axis. it effectively removes the 'turn' on the front axis, so you don't necessarily have to have the extruder (or pen) in the video's case in the exact center of the front facing part. I can snag a picture later on to demo this, which might be useful for printed-out-scara-arms. @jeshua, thanks! The smiley-face was a reference to the movie 'moon'.

Re: [Emc-users] [FWD: RE: Live Config]
It seems that the calibration program will only check the first HAL file described in the INI file. which is ppmc_load.hal. while the values for substitution are in ppmc_motion.hal if you move the setp ppmc.0.encoder.00.scale [AXIS_0]INPUT_SCALE etc into the ppmc_load.hal -I bet it will work properly. I can't test that cause I don't have a ppmc product. Let me know if that works...sorry the answer took so long.

I must admit my question was extremely poorly written. Sorry for the poor grammar and bad descriptions. I checked the hal files as mentioned below and found no spaces before the setp commands. Let try this again. I have uploaded a Sceenshot. I am trying to get input_scale: on Tune 0. Can some one please show me how to ad this. This is hard to explain without looking at the screen. IF you choose to machine config in EMC 2.6 you are able to change and test the axis values while EMC is open. My Y axis is missing the input box to change the resolution. I would like to find out how to add and remove the input boxes for this area. Hi Doug I think you are talking of 'calibration' selected under the machine heading in AXIS? Calibration calls a program that scans the HAL file. If you add a space before the setp eg: setp hm2_5i20.0.stepgen.02.maxaccel 2.5 Calibration will ignore the line and it will not show the box. Next time a little more detail of how you got to the problem will help us help you. And I hope this was what you are talking of :) I hope this helps.
