[09:15:37] <BuildCNCMaster> Isent it posible to USE a G94.1 with a D as Diameter Specification
[09:15:56] <BuildCNCMaster> to Calculate the Rotary Stand alone feedrate in Deg/min
[09:16:14] <BuildCNCMaster> as a ABC Move only is made
[09:16:59] <BuildCNCMaster> so G1 C180 will move at F/ (D*Pi ) *360
[09:18:26] <BuildCNCMaster> most post processors in Cam dont Calculate Extra F in Deg/min
[09:20:58] <BuildCNCMaster> coudt be implemented in the next 2.8 version
[09:23:32] <BuildCNCMaster> so it changes from UU/min into Deg/min on a Rotation only move on given Diameter Calculation
[09:24:54] <BuildCNCMaster> Thanks

[14:58:19] <mozmck> PCW thanks for the sample configs
[15:00:20] <cradek> although I guess the postprocessor could easily calculate that feed, or write an expression that calculates it
[15:01:53] <mozmck> pcw: pcw_home: what does the PID do for steppers?
[15:02:59] <pcw_home> All linuxcnc stepgesn are closed loop in the sense that they are digital oscillators with count feedback
[15:03:49] <pcw_home> the stepgen has a built in loop in the driver (when run in position mode)
[15:03:53] -!- anth0ny_ has quit [Quit: anth0ny_]
[15:05:19] <mozmck> so how does the PID work? you don't move the motor back do you?
[15:05:56] <pcw_home> but... this built in loop is not very robust with respect to servo thread jitter,
[15:05:58] <pcw_home> so its better to use the PID component wheich hase more knobs to tweak
[15:06:34] <mozmck> oh, I think I see a little.
[15:06:52] <pcw_home> no the feedback is only from the stepgen position count
[15:06:59] <mozmck> ok
[15:07:32] <pcw_home> so effectively you are using the stepgen hardware as a velocity mode servo
[15:07:46] <mozmck> another thing I don't understand is what all needs changes in a bit file, and what can be done from the ini and hal files.
[15:07:59] <mozmck> I need to figure out how a velocity mode servo works.
[15:09:24] <mozmck> From what I have heard so far, stepgens are hardwired in the bit file (that's the FPGA firmware right?) to certain pins.
[15:09:45] <pcw_home> changing pinouts of anything other than GPIO (stepgens, encoders etc) require new bit files
[15:09:47] <pcw_home> changing numbers and types of modules requires a new bitfile
[15:10:06] <mozmck> modules?
[15:10:28] <pcw_home> stepgen,uart,SPI,encoder etc
[15:11:01] <pcw_home> all I/O can be GPIO on all bitfiles
[15:11:11] <mozmck> so what does the num_stepgens setting do?
[15:11:31] <mozmck> just tell how many of the predefined modules to use?
[15:11:49] <pcw_home> yes (and unused module pins revert to GPIO)
[15:12:10] <mozmck> Ok, so for GPIO, I presume you can change from output to input in HAL?
[15:12:28] <pcw_home> the hardware can do this on a pin by pin basis but the driver takes a simpler view
[15:13:13] <pcw_home> Yes GPIO defaults to input but can be chaned to output or open drain
[15:13:37] <mozmck> ok.
[15:13:47] <pcw_home> also output bits can be inverted
[15:14:18] <pcw_home> not much use for GPIO but useful for things like stegen/PWM etc
[15:14:51] <mozmck> So would it be hard to make the HAL driver be able to tell stepgens which pin to use for output?
[15:15:27] <pcw_home> the pins a stepgen uses are fixed by the bitfile
[15:16:19] <mozmck> yes, but I'm talking about a hypothetical change - thinking out loud :)

[15:17:39] <linuxcnc-build> build #765 forced
[15:17:40] <linuxcnc-build> I'll give a shout when the build finishes
[15:18:20] <seb_kuzminsky> ok, that should fix the "git auto-gc causes build failures" problem
[15:18:27] <mozmck> crossbar switch - another term for me to look up :)
[15:18:32] <pcw_home> Normally you would want a bitfile to match the I/O hardware
[15:19:44] <pcw_home> mesaflash can print out the current bitfiles pinout
[15:19:45] <mozmck> My thought was that if it could be made a little more generic, the hal configuration would match the I/O hardware, and hal files are much easier for mere mortals to edit.
[15:19:58] <mozmck> oh, I should try that!
[15:20:43] <pcw_home> There really are not that many parallel port stepgen pinouts
[15:20:54] <mozmck> I got linuxcnc talking to my 7i92 last night, but I don't know if the bitfile in it will work.
[15:21:55] <pcw_home> there are about 8 or so 7I92 bitfiles in the dist now
[15:21:57] <mozmck> hmm, that's probably right. Our hardwre wants the step signals in the same pins as the G540, so I think that bitfile will work for me.
[15:22:54] <pcw_home> mesaflash --device 7i92 --addr 192.168.1.121 --readhmid
[15:22:55] <pcw_home> will print the pinout
[15:23:11] <cradek> once you get above 4 axes it gets really nonstandard, but for 4 or fewer axes there are only really the two choices
[15:23:18] <cradek> really
[15:23:33] <mozmck> ok, except I'm using the 10.10.10.10 address
[15:23:48] <mozmck> I loaded the etherhm2.xise in webpack 14.7, and I got about 18 files missing, which I assume is not a problem?
[15:24:04] <pcw_home> OK (thats a better choice anyway)

[15:25:09] <mozmck> Looks like it is set up for the 7i80. What all do I need to change to play with 7i92 files? I presume I need to change the 7i80db.ucf to the 7i92.ucf
[15:25:32] <pcw_home> that and the chip type
[15:25:39] <mozmck> I saw it, but I'm not sure it tells me enough.
[15:26:04] <pcw_home> and select the pinout file and card type in the top level file
[15:27:12] <mozmck> in the file? I assumed you do that in the project manager on the left.
[15:28:26] <pcw_home> those are selected in the top level file
[15:29:36] <mozmck> I have never actually used an FPGA or the xilinx tools yet, so I may need to do some reading.
[15:29:40] <pcw_home> (I use a batch file that replaces the @CARD and @PIN tokens to build all)

[15:30:53] <mozmck> If I un-comment the line "use work.i92_x9card.all; will it automatically add the 7i92.ucf file to the project list in the hierarchy?
[15:31:13] <mozmck> batch file - that sounds like windows :)
[15:31:22] <pcw_home> No that part needs to be done in the gui
[15:31:54] <pcw_home> you can do all this from the command line
[15:32:14] <pcw_home> (which avoids all the mousing around)
[15:32:55] <mozmck> yes, but then I have to know the commands to type, which involves mousing around, or more typing.
[15:33:23] <pcw_home> or just mesaflash the 7i92_g540x2D config if it will do :-)
[15:34:06] <pcw_home> when you get it to compile, the gui leaves the command log
[15:34:17] <mozmck> that's too easy! but probably what I should do. I would like to learn FPGA, but should probably wait.

[15:45:22] <pcw_home> Hmm latest mesaflash?
[15:45:42] <mozmck> this is from the 7i92.zip file I downloaded yesterday - I used the command "mesaflash --device 7i92 --addr 10.10.10.10 --write 7i92_G540x2D.bit

[15:48:11] <mozmck> It's the one in linuxcnc master I guess.
[15:48:57] <mozmck> how?
[15:49:30] <pcw_home> maybe fetch from
https://github.com/micges/mesaflash and build
[15:49:56] <pcw_home> I think there was FPGA name error

[15:51:51] <pcw_home> maybe not reccommended if you dont have JTAG :-)
[15:51:55] <mozmck> Is there a version in linuxcnc master? I'm assuming that's how I got it.

[15:53:29] <mozmck> oh, I do have a xilinx parallel cable iv
[15:53:39] <pcw_home> well maybe if openOCD knows how to progran xilinx

[15:55:31] <pcw_home> yeah that may be
[15:57:03] <pcw_home> normally JTAG shoud not be needed, but is hasny for development where you may make bitfiles that dont work
[15:57:11] <pcw_home> handy

[15:58:07] <pcw_home> normal stuff like changing I/O pinouts is safe (cant make a config you cant access)
[15:58:27] <mozmck> yeah, I'm sure. For my ARM cortex stuff I wrote a bootloader that I generally just have to load once, then update after that through my usb->rs485 hub.

[16:02:15] <mozmck> from linuxcnc that is/
[16:02:23] <cradek> yeah it appears to be the latest
[16:02:33] <cradek> if it needs to be updated we should do it
[16:03:14] <mozmck> pcw_home: what is the mesaflash3 utility in the 7i92 zip file? it does not report a version, but the mesaflash in the same directory is 3.0.0
[16:03:27] <pcw_home> I think the latest changes (other than enhancements) only affect the 7I92

[16:18:13] <pcw_home> you can ues the reload option if you get tired of pulling the power plug

[16:18:51] <mozmck> no reset button?

[19:45:11] <mozmck> I see that pin 16 has a stepgen on it, and that is the charge pump pin on the G540, so do you normally use a stepgen for charge pump?

[20:09:56] <mozmck> What is exactly is velocity mode?
[20:10:08] <PCW> Yes in velocity mode and either set the pulse width to what you want or select quadrature mode
[20:10:21] <mozmck> If you are controlling velocity, how do you do positioning?
[20:10:21] <PCW> man hostmot2
[20:10:53] <PCW> like a velocity mode servo
[20:11:04] -!- swingley has quit [Remote host closed the connection]
[20:11:50] <mozmck> I'll have to look that up.
[20:12:24] <PCW> if you imagine that every 1 ms you set the velocity to the required velocity, other than timebase errors and quantization errors the position would be correct
[20:12:54] <mozmck> I see, that makes sense.
[20:12:57] <PCW> so that what you do, the PID loop takes care of the residual errors
[20:13:42] amnesic_away is now known as amnesic
[20:13:46] <mozmck> so is there a way to get a charge pump signal on pin 17 without making a new bit file?
[20:13:55] <PCW> (FPGA clock <> PC clock, frequency quantization etc)
[20:14:15] <mozmck> I guess I could load different bit files and see what they look like using mesaflash
[20:14:55] <PCW> yeah (Actually I should do that and make the xml file but have been too busy)
[20:15:30] <PCW> you can look at the corresponding 5i25 .pin files
[20:16:21] <PCW> and I can make a bitfile if you send me a desired pinout
[20:16:21] <mozmck> what is the xml file?
[20:16:29] <PCW> for pncconf
[20:17:03] <mozmck> Let me do some looking and see what I can figure out - thanks!
