Re: [Emc-users] Some more Storebro260(FANUC/Sinumerik) docs...
Holmquist, Do find out when the last major mechanical overhaul was done when you encounter machines like this. You will get into untold misery if you think that a retrofit of the computer solves all ills. Customers have this weird belief that the mechanical side is still as new (because it did not break yet) because they _think_ they understand mechanical issues. j.

Re: [Emc-users] Trajectory planning and other topics from a EMC(LinuxCNC) newbie (TheNewbie)
Is the one-line lookahead statement also true blended paths? And how does it apply to splines? I find all this quite surprising, even grbl does lookahead over all the lines in the buffer (and hence has a latency while trying to pause or stop) Does somebody know if this diagram is whats linuxcnc does, or if its just a proposal: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Trapezoidal_Velocity_Profile_Trajectory_Planner Are there any good theoretical books about trajectory planning/step generation that somebody could recommend (non-popular, hardcore numerics preferred)? Arc fitting is not very easy it seems. Of all the reprap slicers, only slic3r can create arcs by looking for repetitive segments of same length and connecting at similar angles . The problem is that the 3d object itself is defined as stl files, and hence exists only as small patches of lines after slicing. And I know of no pcb isolation milling software that creates fitted arcs (while tracing lines in a 300dpi image). There are a couple of algorithms for finding the arc, if you know that some points are supposed to be on an arc. The problem starts when trying to decide, where arcs start and where they stop optimally. very nice greetings, Bernhard On 3/19/2012 4:30 AM, Youda He wrote: This is very interesting, we are planning to.start using linuxcnc some time in near future.

Re: [Emc-users] Some more Storebro260(FANUC/Sinumerik) docs...
Roger, the specifications of this machine just plainly state numbers of its size etc. The control system is Sinumerik 6T like it was mentioned earlier in this thread. It says, however, that the Z and X DC servo motors take 2000 pulses per revolution, so the built-in control electronics seems to take pulse and direction signals. The main spindle seems to be Y and is DC motor driven, 17 kW, and also generates 1024 pulses per rev. The mechanical dimensions and the weight appear to me to be very large considering the maximum size of work pieces it can take. Apparently, this machine is very sturdy built.

My guess is that - since it is a CNC machine now, than implementing LinuxCNC is mission totally possible.

The triangles are applied in the order specified in the file, so there could be a 'later' larger triangle enclosing or overlapping an earlier one. The algorithm currently is based on a brute-force test of all triangles until first match.

Re: [Emc-users] Tool change question
It is funny what people think should be a standard feature because it is what their machine needs. What you really need is an automatic tool changer. I can jog,ride a bike,have a cup of coffee,or do most anything during my tool changes.(I am sorry I could not resist.)

On a more general note, being able to touch off after a tool change seems to me to be a necessary function for any and every milling operation. Why doesn't EMC2 have this feature built-in? Or, to put it another way, how are users of EMC2 currently determining the new z offset after changing tools, assuming they don't use a probing feature? Just curious. See below. please see the example in http://git.linuxcnc.org/gitweb?p=emc2.git;a=tree;f=configs/sim/remap/m an ual-toolchange-with-tool-length-switch;h=8c716f10d20a9f0722de83dda3fb 393 087d94270;hb=10d8caf753ab0269f882d83b59a6c76e2e3ae28d this can easily be adapted to other forms of touchoff -m I am not aware to a method that doesn't at some point make use of the G38.2 function, which means there MUST be a probe of the tool. In my case, doing pcb work using eagle pcb2gcode, I wrote some routines that assume the probing pin is connected to the pcb itself. In my case, the use of the routines requires that calls to the probe function be manually edited into the pcb-gcode output to command a move to a location that clears the work space for the tool change, and after each tool change call the subroutine to establish the offset. As I tend to run with rather leasurely accelerations, my probes are done relatively slowly so the tool doesn't overshoot and mark up the workpiece, so each probe adds about a minute to the production time. I also added a bit of a fudge factor so the 'etching' depth can be controlled without having to rerun pcb-gcode and then reinstall this stuff by editing in everything all over again. At my web page in the sig, add /Genes-os9-stf/eagle to the path and you can download the 3 files I use. tedautoz.ngc (tOPeTCHdRILL.ngc) bedautoz.ngc (bOTTOMeTCHdRILL.ngc) tholefinder.ngc PCB-Pallat.JPG tholefnder.ngc is written to use a short piece of tubing let into the pallet that holds the pcb for etching, and the offsets it develops as it runs set the left-right offsets in G55 and G56 modes so the top etch, top drill, matches up with the bottom etch and bottom drill files. PCB- Pallat.JPG shows fuzzily, what my pallet for that first board looks like. The grayer area in the center has been relieved another 25 thou so any machining burrs left from the etching and drilling of the first side do not prop the board up and mess up the bottom side by etching too deeply. tholefinder.ngc will of course need editing so that what it discovers will work for the pcb carrying pallet you'll need to make. I made mine from some 1/2 micarta I bought a couple slabs of from Highland Hardware in Hotlanta, intending to make zero clearance inserts for my BT-3000 Ryobi table saw, something that saw is very badly in need of since the plastic casting they sell comes out of the box sitting 50 thou too low all over, and over .1 low at the top center of the blade. I made 2 zero clearance inserts, and haven't damaged the first one yet. Piece of crap factory plastic I won't every buy again. The micarta works great. Cheers, Gene I forgot to mention that the pix of the pcb pallet doesn't show the machined fin on the bottom that fits the T nut slots of my mills table in order to maintain x alignment when its removed remounted on the mills table.

Something else I'll need to learn about. This is not to say the the firmware in the FPGA module could not be taught to speak MODBUS Right now I'm interested in talking to VFD's and other userlandish devices. Most newer VFD's seem to have Modbus and could make more features available without adding more hardware or cabling.

Maybe more like if your are going to respond, you better do it within 3.5 character spaces. It also supports discovery which I dont think is possible with MODBUS but Im not sure of this Modbus has a Report Slave ID query which should return more than just an ID.

[Emc-users] SCSI to tape interface
This sounds OT, but has a tie-in to EMC, as we are trying to be able to read a tape that has the last work on APT/360 on it. I have a CDC Keystone 9-track tape drive that appears to be working fine. I have a salvaged SCSI to Pertec formatted interface converter that worked for a while, and I was able to dump a few blocks off some tapes with it, then it died! So, does anyone know where to get a SCSI to Pertec formatted interface converter board? Or, does anyone know where to get the SCSI interface board for a CDC 92185 tape drive? Or, does anyone know where a working 9-track 1600 and/or 6250 BPI tape drive is that we could read some tapes on?
