| Thats not the actual one. I found that on the web. But the one where I work is also a Bridgeport, very similar setup, except it only has numerical readout on the x and y axis. The one in the photo looks like it has z as well. |

Either way, that panel is beautiful!

Yep, I second that. Very nice layout photon!

Thanks guys
Yeah, I'm really looking forward to this one! I had to finish a few modules before I could justify jumping in to Kleedom. Now theres nothing holding me back (except work, wife and a few other minor obligations like sleeping)

I still didn't find the time to debug my Klee but I manage to become a father.
Andrija is the guy. Healthy and beautiful 
Pretty cool.

Infinitely more important than debugging a Klee. Congratulations!!!!!!!!

[Edit Blue Hell: shortened the link] |
It is not clear to me what rotary switch is. The link to the pdf is general information about it.
Could anyone tell me what rotary switch is needed for the Klee? |

The voltage scaler uses a rotary to choose what the max voltage will be. This is the voltage which will be the max value for each pot/slider. The board is set up to use an eight position rotary switch. If you use a binary encoded rotary, you can bypass the diodes and connect straight to the 3 address lines. (which I put extra pads on to help with this and other mods)

Right. Most rotary switches have a maximum number of positions, but allow you to set the number of actual positions you want on the switch. For example, the switch in the PDF mentions that it has an adjustable stopper plate that allows anywhere from 2 to 12 positions with the switch. With the Klee, you would set it to 8 positions.
Cheerios,
Scott

So, generally, you would need an 8 throw switch with a single pole.

Unless you went with Uncle K's BCD arrangement, of course

Very, very interesting... I didn't know what was a encoder... so... with three toggle switch I have a encoder also  only three diodes?
Anyway I see that the NKK rotary don't have a 6mm D shaft.? for put the same knob all.
I go ahead looking for encoder or rotary switch with 6mm D shaft... or... three toggles... |

got to my Klee this morning.
I did the 1K resistor over manual step switch and it is working like a charm.
Advancing one step how it should.
And when unplugged from PSU with man. step pressed resistance between +12 and ground is 1K26.
Did I do something wrong? Why is this? |

No, I don't think you did anything wrong. Back when you first reported the problem, I measured the resistance there, too, with the power off. My resistance was actually a bit lower - I owe that to the fact there's a lot of stuff between the switch and ground that is in the off state.
The step switch was the biggest PITA of the whole proto process - IIRC, the original design worked fine for me and fine for Tom - I think Andy's did too. Bill's proto would skip steps (IIRC). We did a lot of trouble-shooting and research into different methods of debouncing the switch. If you've got the time to check the original Model 2 schematics against the electro-music Klee, you'll see that portion was beefed up and rearranged a bit.
With the configuration we came up with, all four protos operated reliably and correctly, but it didn't quite explain why they didn't with the original values. And, you may recall, I experienced something similar in the early stages of breadboarding - I got around it, but I never understood it.
My theory is, what it boils down to is that the circuit relies on current going to a certain point within a certain amount of time, which is controlled by capacitance. In a circuit like that, I think a certain unknown is the inductance of the wiring that will occur from build to build, and inductance does play a part in such a circuit. Now, why that would have the effect on the power supply it has is beyond me (a brain of Ian's size would need to step in there), but that's my theory. In the case of the breadboard problem I experienced, I could put some more resistance in at that point (like you did), or I could just tap from ground further down the line -either method worked for me at the time.
Having all the protos work gave us the confidence to be able to get any step switch to work should anyone encounter any problem with it (assuming the momentary is a decent switch). I think generally, by and large, most of them will work right off the bat. Should there be any funkyness in anyone's build, we know pretty much what to do.
What ground point did you use, BTW, during the 1K tap test?
Oh, and please, if you find the time, post a pic of that bad boy with lights ablazing - I'd like to see that
Cheerio,
Scott

I just connected two pins of that switch together with 1K resistor.
One of the pins is connected to digital ground.
You want picture of manual step switch? |

There's your problem - the wiring is too neat.

... and you say when the unit is energized and you activate this pushbutton, the 12V supply gets loaded ?? and .... When you bridge these very same switch contacts, it does not load the supply and the unit advances correctly? Are my facts correct ???
Thanks

Now that's more like it
My Klee is still early contemporary rat's nest......

jep you got it.
unplugged resistance +12/ground is 1K26
plugged goes crazy and freez psu
bridged with 1K works ok |

Mouser Switch Recommendation? |
|
|
| I kinda went ape this weekend and drilled out two panels for my two forthcoming Klees. In preparation for stuffing parts onto the panels, I need to order switches. If anyone has has ordered theirs from Mouser, which part numbers did you order? |
