Re: [Emc-users] 7i76 and spindle control
Andy, Gene - I do have a spare 12v linear regulated supply and a nice small 5v switching sitting by my new mill, was going to prototype with the 5v first. (KBIC says 0-7v input in voltage follower mode - 0-5v will get me going) Interesting about the dc-dc converters; on reading, as Gene says, some are isolated, some are not. The local store does have lots of switching power supplies of varying voltages, and I do have a large metal box for all of this to go into, but I dislike clutter. So, I'll see if the local store has a 12v 12v dc isolated converter that is small and compact. I appreciate the isolation warnings; while I do realize that I'm playing with 110v, 15A here, but it is nice to have the reminder, and also, for others who may stumble across this thread. Thank you!

Very few switchers are capable of dealing with that and will go into over voltage protection shutdowns. So anytime I'm not pure steppers, I use a simple transformer and cap supply, it doesn't bither them a bot. :) The fact that it needs a 2 wheel hand cart to move it any great distance is beside the point. What I finally wound up with here, to run a 1 HP rated escapee from a treadmill, has a 2500va transformer and a need for a strong back to move it. Parts cabbaged from an old Phase Linear dual 750 rms watts a channel amplifier, and caps from an IBM printer that was about the same size as a 17 cu ft chest freezer when it was alive. The Phase Linears caps were only surge rated to about 125 volts. But I have 150 volts for a surge margin using 2 of the IBM caps with a 5k equalizer bleeder across each, wired in series. I think I can weld stuff with it. Evidence of that is a nice steel cookie socket in the side of a wrench that shorted them a day after it had been turned off before I added a 7 watt xmas tree lamp to the output for a bleedoff. Takes several minutes at that, big caps, 3 in diameter 7.5 tall. 19,000 uf IIRC. So, I'll see if the local store has a 12v 12v dc isolated converter that is small and compact.

The shape of the pulses control how the drops and satellites are formed and ejected from the nozzles. Piezo heads are more difficult to drive than thermal inkjet heads. Thank you everybody for the ideas. We decided to start at checking with oscilliscope, what is goint on in the signal lines on the printer head, when it is working.

You can use an isolated external supply of 5 to 12V It might be important to stress isolated there. The KBIC controller float the pot at +100 volts or so. I'll add even more emphasis to this warning. We tend to forget that which Just Works(TM) One solution is probably a small 12V - 12V isolated DC-DC converter connected to the normal 12V DC. That is another avenue, and a actually a good suggestion as those are generally less costly than a line transformer powered solution and considerably smaller physically. Since this circuit generally needs less than 20 milliamps, if no 12 volts is available but 5 volts is, there are 5 to 12 converters available too. But they MUST BE TRANSFORMER ISOLATED, the charge pump designs have way too much leakage coupling due to the use of capacitance for the power transfer method. Leakage that can destroy circuitry if accidentally grounded, and kill you if you are the grounding medium. :( Good advice Andy, thanks.

With the appropriate hal connections (and possibly support circuitry) one could use the dir line to control a DPDT relay. I actually have a little board with a couple of ULN2003 chips on it, controlled by the 7i43, and use those to set on and dir for the VFD. There is also a channel that swaps between the mill motor and lathe motor, as the same VFD drives both on the dual-purpose machine. (The board is actually plug-configurable to allow any GPIO pin to use the input and output buffers. I have no idea why I bothered, I have never changed the configuration.

Re: [Emc-users] using 7i43 as a stepper controller
Thanks, Andy, I wondered if my email had BO. It is interesting that they show up in the archives and in digests, but evidently get spam folder-ed for individual e-mails. I can’t find them now. I get the user and dev digests as well as I read some of the forum stuff. I suspect that I saw something in the middle of a thread where someone was setting up a closed system and I missed the part about closed loop. I don’t have encoders for my steppers (yet). So I will initially set up position mode.

Typically you would use velocity-mode when the steppers are part of a closed-loop system. It would work with encoders on the steppers, and possibly even better when combined with linear scales.

Heck, if that is how I'd have to do it, rather than less, which of course I did do at the time, I'd pipe it to | lp -dBROTHEHL2140 -, and get some exercise running to the basement to get it off that printer so I could go down the list putting a checkmark beside each process I restarted. With my bum knee, going up down those steps one at a time using the right knee for all the bending and climbing, I'll warrant I can reboot it quicker, and KNOW the job is done right. The point being and that you seem to be missing is that every process that used bash would have to be shut down AT THE SAME TIME in order to purge the one copy of bash thats in memory, sharing a different stack pointer for each process its associated with. So I'd doubt that just going down the list with a service xyz restart would ever pull a fresh copy of the just installed version into memory, not when there is what the system thinks is a perfectly good copy of bash already in memory, locked there by 40+ other processes using it. You aren't thinking like the os thinks when you assume a simple restart of each used process will reload a fresh copy of bash per process. Simply put, tain't gonna happen. I'd go so far as to say that no os on the planet loads a separate copy of bash on a per process basis. So reboot the sucker and KNOW its done. Multi-user, multitasking os's like Unix (1970's-?) or OS9 (1982-?), never did that simply because there was not enough very expensive memory in those ancient machines to even consider loading a private copy. I can recall paying $400 for an s100 board kit with 4k of static ram on it in 1980? OS9 was my teacher about how a Unix like system worked and one of the reasons the M$ system has not been allowed to survive on the premises more than a week or 2 after I had bought the machine. And that only once, when I needed a lappy for on the road use. But it had an early Mandrake on it buy the time it hit the road the first time. This BTW is not the Mac pre-bsd OS-9, but the Microware version that first ran on a 64k, floppy based TRS-80 Color Computer. I am very familiar with that os as I did major work in several pieces of it in converting it to run on a coco which had had its cpu replaced with the considerably more intelligent Hitachi HC6309, one of the best kept secrets in computers ever. I also patched the Random Block File manager so that up to 4Gb hard drive partitions can be used, on a system that was all tapped out at 128 megs for the whole drive in the original version. Sysadmin? Yes no. The devil is in the details, those I have to ask about, Mark, but the basic principles about how its done internally are not a puzzle, just the age creases in the faces (and blackhead locations) change according to the logo's on the box it came in. And linux has most certainly caused a population explosion with its varieties, each of which has its own preferences for wash soap face creams to make it look as good as it does on the outside, with, as we all know, wildly varying degrees of success in the pretty face dept. Some of them have been Coyote Ugly over the last 16 years I've been using it. ;-) Cheers, Gene Heskett -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
