An oscilloscope can show if the sinus is of an even period. A device can move the reader head colinear with the scale.

Hello, I am Tom Powderly from Elgin IL
I knew of PumpStationOne, but it wasn't close ( or free ;)
anyway, lets simplify a complex problem a bit
1) try to find an original yourkins.c or reconstruct it ( gotta be done
anyway)
rest of comments are interspersed inline
On 06/22/2013 07:19 PM, Bart Dring wrote: Hi,
I am working with a group of CNC builders at the Chicago HackerSpace
Pumping Station One. We are building a simple 2D drawing machine. The
machine uses 2 belt driven carriages on a single linear bearing. You can
see the details of the machine at this link.
interesting machine, Hr. (Dr?) Till Franitza built similar at a school
( i remember the scissors action and it being a plotter )
i can only find a newer version (X with a polar swing arm Y ) as a video
http://pumpingstationone.org/2013/06/cnc-gonzo-build-2-recap/
We are having trouble getting it to work in EMC. When we turn on the
machine in EMC, both carriages immediately race at full speed towards the
home switches. They trigger the switches, but keep trying to go. We
looked
at the switches in HalScope and they appear to be functioning
properly. If
we use F2 to quickly turn the machine on then off before the carriages
crash, we can turn it back on and the carriages do not move spontaneously
anymore.
heehee 'anymore' an american euphemism that is hard to understand
and impossible to translate
but i get it that it used to but not now..
ok
need a youkins.c still
then it can be debugged
Using the MDI tab with G code commands we are able to get X motion at the
pen. That is pretty simple because for X, both carriages always run
at the
i see how the 2 joint Y travels along X, and worried at the limitations
it has near X limits,(just to say i get the mechanical side of it )
same speed and direction as the pen. We can command the pen to move in Y,
but only at very low speeds.
ok, this infers the X is ok at higher speeds. true?
and does the motion seem correct?
(speed correct, expected size of motion correct?)
If we try to go fast EMC gives us all sorts of
joint speed and position errors.
ok, unexpected to you, i agree, but they indicate the problem
you HAVE TO record the errors, its trying to help you solve the problem.
There is a link to our kinemantics file at the link above. (We just
modified trivkins.c). At this point I think it has been hacked beyond our
initial successes, to completely broken.
yep, you need a new .c file, (AKAC always keep a copy)
1. For this type of machine, what do we return for kinematicsType()?
copied from include/kinematics.h
KINEMATICS_FORWARD_ONLY, /* forward but no inverse */
KINEMATICS_INVERSE_ONLY, /* inverse but no forward */
KINEMATICS_BOTH/* forward and inverse both */
if this is the Q, well you wrote , and have the answer
( country, western, or allkinds ;)
do you mean for the INI file entry?
if so its the name of your .c file without extant
eg: jumpylinekins ( compiled from jumpylinekins.c )
the name is set up in yourkins.c like this stanza in gantrykins.c
...
int rtapi_app_main(void) {
int result, i;
comp_id = hal_init(gantrykins);
...
2. What do I want to do in kinematicsHome(). When is this function called
and how often?
i'd say youd want to call it after you were AT home,
and in it, solve the known 'axis' positions into 'joint' positions
( this means something like, i know i'm at the home switches for each
joint, and i know this should be a specific XY position,
but i have to solve for where the Ya and Yb are now. (Inv Kins tells us)
reading other src files is often helpful in Linuxcnc
heres what is said in genhexkins.c
/*
kinematicsHome() is implemented by taking the desired world coordinates,
which are passed as an arg, and running the inverse kinematics to get
the resulting joints. The flags are set to zero.
*/
how often?
well at least do it before you want your work to be measured from a
known position.
once after the machine does not know where the reference ( home
position) is located ( after loss of power, on start up, after steps are
lost )
short answer:
use the name of the id you setup in your blahkins.c , tell THAT to the
.ini file
home once after power up
3. Why does the machine starting running immediately.?
i'd have to see the code and thinkabit
the machine shouldnt immediately move, period
it has to be told to move ( well a servo can run away, but i saw
steppers )
your physical ( copper ) and logical ( hal net ) wiring should not
allow this to happen
4. Can everything be done in the mykin.c file or do I need to modify
other
areas of the HAL.
everything is hard to imagine, you'd best begin simpler
and work thru intial problems
rather than do anything that uses 'everything' in the description
quick simplistic answer: yes, the kins is sortakinda isolated

Many filed attempts and loads of bad / outdated web info. The successful install went this way: I used notes from http://dreamrunner.org/blog/2012/09/12/install-xilinx-ise-on-the-ubuntu/ I used the Linux download, and for that the single file download. Dont use the multiple file download, and no special downloader was used. Just check the csum. This too about 6hrs with my internet provider in USA. You'll need a load of space, say 250% of the download size to download AND extract. You'll need another 150% of the download size where you want to install I used one partition with 34G free for the download and extract, and another with 26G free for the install target. During the install, you'll be asked for a license. A separate program runs to do this. I requested a WebPack license. This is important trick! Install FULL , but use WebPack license. A few libraries were needed, see the dreamrunner link During the install it will ask if you want to install the drivers. The web consensus is DONT DO IT YET! I have not gotten to the point of communication with a target yet, so cannot offer personal experience, but many say this is the correct approach. update: I did build the drivers, tho the script had a small change for the version number ( 12.x to 14.4). They built fine but I dont have Jtag header on my card yet and have not tested. So I cannot prove that mine works. The suite is invoked by running a script, so the script needs to be executable and have sufficient permissions ( settings32.sh for my ubuntu 12.04 shell ) to get a desktop icon, i followed http://followthegeeks.com/how-to-manually-create-application-launcher-in-ubuntu-12-04-unity/ the icon is in yourpath//Xilinx/14.4/ISE_DS/common/idata/usenglish/idata/isebillboards/logo.png I also downloaded the zip files for tutorials I ran the entire set of tutors for vhdl. There are tutors for vhdl verilog and schematic input styles. This exercises many features of the the suite The editor, Syntax Checker, Simulator, Bit file generator, schematic editor. These all worked. Again, I have not programmed a bit file to a card yet. but i know the program suite works. PS. It never crashed for the entire tutorial, seems very stabile, but is a bit slow on my system. Dont panic if the system is building and you see no feedback, just wait. Your last Q about how to modify .xml, .BIT. and .PIN files, well AndyPugh is right, you modify the .vhd files (if you use VHDL as your chosen language/definition style). I do not know which .vhd file you would need to modify for your project. You can get all the .vhd and .ucf files from the GIT repository. Examining them will show you more about the process. Following the Xilinx tutorials will explain the relations of the files in a project. I'm just learning all this myself. best of luck TomP

Erik, hello, Basically, yes :) The depth and diameter is governed by the joules expended per discharge, A fixed on time does not account for the pulse to pulse variation in ionization time ( how long it takes current flow to begin after voltage is applied). So I do not decrement the desired on time value until the current begins to flow. This makes the joules per discharge equal, and in turn, makes the craters equal.

Updating was painless and we looked at the port with a scope to double check that the step/dir pin locations had changed. I had found someones 5i25 config on the forum and set it up for Pete_G hardware. (he isn't using any daughter boards yet.) This is the email I got back from him after running all day sunday.. Hi Sam: I set up the Rutex based controller on by Bridgeport mill, edited the scale values in the .ini file and went zooming. It went in the right directions, and fast. I ran out of nerve at 3/4 inch per second/ 45 IPM. The machine never went as fast as 35 IPM before. The linuxcnc has a much nicer interface than the ancient version I was running. I like it a bunch. Thank you for working with me on this project. This is a great improvement over where I was. So that is a big YAY - he has a Dyna 4400 that he has starting converting. Thanks Peter(mesa) for your quick firmware mod and the overall coolness of your hardware :) He also talked a bit about his edm (couple emails). (his own software) You mentioned that my name came up on the list-serve about EDM work. Attached is a picture that shows a little embossing wheel that I made with coordinated X and C motion and a sample of wire EDM work I did. In both cases, the software executes the G-code forward and backward, whatever it takes to maintain the erosion gap voltage as needed. The sinker software will back out on a programmed basis, either along the pathway in or toward pre-programmed escape points. The wire program backs up a specified distance (regardless of the number of line segments traversed) and then follows a small X, trying to clear the crud and get sparking again. If that fails, the motion stops but controlling the wire travel speed or shutting off the wire was not included in the program. One day i'll do that and add other necessary features. I also have a picture (not attached) where I eroded with coordinated Z C motion and threaded a hole in a file. Attached is a picture that shows the roll-die and the threaded hole. For flushing, the threading electrode backed its way out of the hole. When making the roll-die, it was rolled across the face of a flat electrode with coordinated X C motion, with escape moves in the +Y direction for flushing/ gap contamination. You can post either of both of the pictures. I should have explained that the escape moves and backing out for flushing are NOT part of the g-code. The programmer couldn't possibly know at what points the electrode would need to be backed out. My software monitors that gap voltage and when it is too low it will create it's own destination_X, y, z, c values to move to in order to clear the problem. Once the erosion gap returns to normal, my software erodes its way back to the where it escaped from the program path and then continues on the programmed path. The key to EDM is to monitor erosion conditions (voltage) and to move forward and backward on the programmed path to maintain erosion conditions. Or escape off to the side if needed. Some people insist that there must be a feed rate in EDM. There is not. pete Thanks to all for all the hard work on the linuxcnc project!! sam -- Everyone hates slow websites. So do we.

So far, the tools seat well enough without using the keys. It is probably possible to carefully align the spindle for tool-change if there is a spindle encoder.

Unlike the more acute self holding tapers above, such tapers are not designed to transmit torque. This turning effort is carried by driving keys engaging slots on the flange. However I have trouble seeing how you can hold a CAT flange and still allow the dogs to engage. BT flanges have a gripper groove which is far enough below the keys for there to be no interference. ( http://www.bright-tools.com/news_show_79.html) There is rather less space on the SK flange.

Semi-circular ring with a spring driven pin to go in the groove. Rotate in, come up, clamp the tool holder, move down, rotate, come up, go down and to rest position.
