Wow. Looking at your pics I'm feeing like a bit of a hack. My enclosures are not nearly as finished as yours. I often wonder how my k and analog live in the enclosure of my first machine. Things...

Ok.

I do know my favorite aftermarket controller is the dynomotion kflop.

But I was wondering how many out there have multiple machines using the k

I presently have 3
1. Kflop / kanalog...

Would anyone happen to know the turns per inch (or turns per Centimeter) that Hermes / Gravograph used on their IS8000 XP engraving machines?

Thanks..

I have gotten a lg900. Now. Was new when I got it basically. Another guy imported it then sold it to me with pretty much 0 miles on it. Mine is a 100w equipped unit. And I to have noticed...

The bolt pattern on these are standard for the model. Pretty much all of this style use this same bolt pattern. (although one of the 2 I got had 4 extra holes off set from the normal) My earlier...

Hopefully ok to do so. but wanted to post contact info for the source of the spindles I got. This will make it more clear who the seller was and all.

Units looked great and work well so far. ...

Ok. Good to know. I didn't see the lower openings for air flow and couldn't see a top view to see fan

Either way newer to match dimensions more then anything else and not sure if the turkey ones...

Also, The hole in the one styrofome package was done by customs (was covered by green customs tape). So they looked at this box anyway ..

b.

One of my requirements was that they match in dimensions to my existing units (So my clamp on items and dust skirts and such fit) so from the looks of it the Hertz spindles would not do that. ...

Hello..

wanted to post about the spindles I imported today. ended up getting 2 18000rpm 2.2KW 220V 10A 300Hz ER25 Air-cooled Square Spindle Motor from vipwindows_168 on ebay ...

I've heard getting parts for the old techno machines should be no problem. But aside from armors post, I just got a pretty old techno machine, and other then the long ball screw being pretty badly...

Ok.. Been looking at the unit I have, and looks like interfacing to the existing driver board should be pretty easy. Mine has a MC74HCT244A chip as the logic input for the step and direction...

Does any one know what size resistors Aminear used in his connection setup? Knowing that would be of great help

thanks..

Did anyone ever end up having a breakout schematic for the 7000 machine? I ended up with one and figure I'd either interface it parallel to the existing stepper drivers my self or replace the...

I have gotten all 3 of my spindles (2 C73 and a C 78) and they have been great units for years. Fan cooled VFD spindles so you don't have to deal with water cooling like on the china ones. Perhaps...

Cool, Looks like I can get movement in the step/response screen with this servo. Nice and smooth (as expected, just takes a bit of me trying) Now just have to remember PID tuning, although this...

Ok. Will try that tomorrow

Thanks

Now I think that looks correct. Is it ok to use the opto intputs for this speed/reaction wise compaired to the ttl? from the schematic, it looks like there is a series resistor to the opto so they...

Success, I think..

Anyway connected the output of the I encoder wire to the one of the opto + signal inputs, and grounded the opto -. And then changed the !zmark and zmark commands in the...

The differentials toggle nicely on the meter between 3.3v and 3mv when rotating.

Sent some mail to teknic asking about their servo I output and what it could drive. See what they say. They had...

Ok..

Counts are for sure nice and smooth in the axis screen, I don't think it is having any issues seeing the differentials.

Best I can do for the moment is watch the I signal with my meter....

I didn't make any changes to the code far as the parts to find and react to index pulses. It does not rotate 2 forward most of the time. Uasually only rotates around 1/2 turn forward then 1 or more...

Here are my find report numbers with the ignore at 300.. Running it alone with out all the extra prints and the other thread running (blinking the LED)

I want to say it looks like it is doing...

Ok Connected I signal to pin 1 and 180ohm to Snap ground, changed the detection code in thread 2 to io bit 80 as well as the find code to 80

Still get the same results (random blink ish on...

Ok. was thinking about this before but thought perhaps the resistor to A- help the differential.

Will go play now and let ya know. I can get a different size resistor as well. Just don't have...

Lowered the phase to 10 and 8, just makes the rotation strength pretty weak and slower. But still blinkey blink on the I index detector..

So It is not a differential signal on the I (knew that)...

5v and ground is supplied from the 47 and 49 pins of the snap

Yes that is the servo type..
And have run amplitude 10 think that was the default. currently it might be higher but I was not rotating right before because my phases were not all connected right...

Ok.. Cap does not do anything,



once the program is finished and you can rotate the servo again, the residual mag or what ever does make it dificult to rotate, even with the power supply off...

As you suspected, blinks at random while rotating/energized... Also the servo gets pretty hot sitting there after a while, was going to ask you about that. The fet temp has not gone over 25c...
