Joysticks are a bit too easy to knock for my liking. Seb wrote a component that uses the Linux HIDRAW driver to get the button clicks as HAL Booleans; the Ring is encoded as -7 to 7 for the 14 speeds and stop; the inner wheel gives a signed count updated on each click. This is in the current LinuxCNC releases and so Machinekit. man shuttlexpress gets its doc. I have a very simple COMP that translates the ring position number to an arbitrary range of speeds defined by 7 input pins, latches the buttons for axis selection and supports different step sizes. It can be done in HAL but IMO the C is much more transparent. Thus device does not need a Tormach machine tool to be useful. The Tormach version has silk screened labels but is internally the same as the stock unit sold by Contour. Best wishes John Prentice -- CenturyLink Cloud: The Leader in Enterprise Cloud Services.

I like the fact I can move an exact amount without looking at the screen. When cleaning up a surface or edge, I can move, say, .010" by turning the encoder ten clicks, without looking at the dial or the screen, just keeping my eye on the workpiece.

You have to enable the USB networking emulation, which IMHO is kind of an abomination*. If you really want to do this, follow the guide of your choice for configuring Debian networking, and you can use the shipping BeagleBone setup as an example. Or if you're really ambitious, feel free to get the networking setup code from RCN's upstream omap-image-builder scripts working with MachineKit image builds.

(*) It's not that Ethernet over USB is all that bad, but the way this is setup by default on the BeagleBone, the 'Bone will not have working DNS, can't see the internet (unless you are _very_ crafty at setting up networking on the device you connect to the 'Bone), and generally almost nothing running on the 'Bone will work with networking in any sort of way that you would expect.

thank you for the help. I was just wanting to demonstrate the setup at a place where I wouldn't be able to get on a network for the demonstration. I guess I could always just bring my own router to go between my laptop (which wouldn't be connected to internet at the time) and the beaglebone. thanks.

Re: [Emc-users] beaglebone machinekit usb ssh
I'll admit the USB network setup can be handy at times (especially if you don't have a USB serial cable), but I haven't tried to get it setup. It shouldn't be too hard, since I believe RCN is enabling it in the Debian builds intended to replace the Angstrom disto loaded into the eMMC at the factory, but I have approximately zero need or desire to make USB networking function, and a lot of other issues to fix. If you do get something working, share the results and I'll try to get it folded into the image build scripts.

[Emc-users] Reading high count encoders at high speed.
Ok - another crazy idea from the popcorn gallery. To use an analogy, Gecko Stepper drives work some math-o-magic in the internal FPGA to transition from 1/10 step mode to full step mode without loosing position. An idea I had was to do something like that when trying to read high count encoders at higher speeds. Once the velocity has passed a given threshold it is known which direction an axis is moving so at that point is Quad still really needed? Could you just continue to count the leading edge for A and use that for velocity tracking? I know adding mode switching check code bloats up the basic system, and maybe for parallel ports the timing may be such that you can't just pick up the leading edge. I just thought this might be a viable option for low CPU power machines such as a Raspberry Pi or BB or even an old paraports only PC.

[Emc-users] MPG ilowpass vs limit2/3
We have MPG 'banging' on two machines that are tuned fast and I just found the 'ilowpass' example fix online: http://linuxcnc.org/docs/html/examples/mpg.html Looks to be a FIR filter. I had actually found the 'limit2' and 'limit3' functions first to use as rate limiters when searching. There is also the regular 'lowpass' function. Any reason to use them over ilowpass? Im just wondering if there is some backstory like ilowpass was developed before the other functions were or somesuch.

ilowpass is a low pass filter with integer inputs and output so matches the
integer counts from the encoder component and the integer count inputs
of motions jog pins without having to add a conversion function.

I think I was the first person to complain about this, and Jeff Epler whipped up ilowpass while I was talking to somebody for a couple minutes! Literally, just in a couple minutes. He needed to whip up an integer version of the float lowpass as the jog input to axis is an integer. This was probably at the 2007 CNC Workshop in Galesburg, IL. I'm still using this scheme as it seems to work very well. Jon -- WatchGuard Dimension instantly turns raw network data into actionable security intelligence.
