"k2scope"

I've acquired 2 or 3 K2 IND systems and have mixed/matched parts to combine them into a working system.

Basically what happened was I tried really hard to get one at local auction but kept getting outbid. I found one at reasonable price on eBay (after some negotiation) and acquired it. However, it didn't come with any objectives. Somehow after this I managed to win a very nice system at industrial auction for pretty low price (lower than the objectives would have cost on eBay). I ultimately had to mix/match parts from the two systems to get good optical quality.

Nikon clamps are 8-32 (revolving nosepiece and such)

BOM

Given the quality of this system and how much I bid to get other systems, this system has been surprisingly low cost to build.

Combining parts into a working high quality system composed of:

Encoder details

Cover removed:

Glass rotary encoder with open drain outputs.

I opened this up because I was having trouble getting signal (2014-09-29) and thought it might have been broken. Now I know it was just an open drain vs actively driven issue.

When I asked Gecko about my linear encoders they didn't seem that familiar with them (which seems a bit odd but w/e). In any case, they recommended the follow qudrature encoders:

• • CUI AMT102-V
  • US Digital quadrature encoder

Driver box

Had a driver box but it got lost in the move.

Trying to troubleshoot why not moving. Notes from a while back

20 mA drive required "TTL level" 100 ohm resistor + diode (3.3 V - 0.7V) / 100 = 0.026

Currently using 5V. Is that somehow too much?

Driver boxes are on: motors are locked in place. Any chance the shutdown input got triggered?

Double checked pinout vs above and it sounds like its wired correctly with step/direction

Maybe try switching them if its backwards somehow?

Can't find the k2 stepper config. How many steps per mm?

M-Drive manual has note: TTL Inputs: 3.5 to 6.0 V pulse height 500 ns pulse width minimum 20 mA minimum current 1 MHz maximum pulse rate
