Tools required for Assembly and Testing the Mardus-Kreutz Drives


  • Soldering Iron 25 or 30W, (temperature control is desirable but not necessary)

  • Soldering wire (Rosin core, 37/63 or 40/60 0.032 diameter or equivalent) or PB free.

  • Desoldering pump (Soldapult or equivalent with anti-static tip). Desirable, will be handy if some rework is needed.

  • Small wire/cable cutter Tool.

  • Multimeter.

  • Oscilloscope (desirable but not necessary).

  • Lab power supply (desirable but not necessary).

  • Fine Long nose pliers or equivalent tool.

  • Small screwdrivers (flat and Phillips tips)

  • Insulated wrapping wire AWG 30 (solid copper twisted telephone wire or Cat5 solid twisted pair network wires could be used too) for prototype perforated-board wiring (not required if the translator PCB is ordered)

  • 10 Conductor ribbon cable and two 10 pin female IDC connectors (Translator to Power Stage interface cable) Lenght is user dependent (the shorter the better) maximum 12".
  • Anti-Static mat with ground cable (the link is only one example)
  • Anti-Static Velcro wrist-strap with ground cable (the link is only one example)

On the internet people are generally recommending Weller soldering stations.

How important is a 'good' soldering iron ?

What type of soldering tip is most useful for assembly ?

Kreutz said...

Weller brand is well known, mine is an adjustable temperature WESD51 with PES51 Iron, the tips I use more frequently are: a fine conical tip for some easy SMD rework, and the fine spade tip for through-hole and general soldering.

I also own a Master Ultratorch 100 Watt butane soldering Iron for thick wire soldering, soldering to ground planes, and heat-shrinking tubing.

In general, I recommend buying good tools if you plan to use them more than once.

Hi Kreutz,

some questions regarding the BOM:

This is the update from 12/05/2008:

Here is a shopping list assembled at www.octopart.com:

http://cnclayman.blogspot.com/2008/12/cnc-mardus-kreutz-components.html

As you can see, some parts are not found yet
- how does one order these capacitors
- are the resistors the ones with the color rings
- are any additional parts needed
- Jeff asked:
Hi I was using your BOM and noticed the newark part no. of 12J4018 is rated for 5 amp. Would Newark no. 46F1532 be a better part to use?

Thank you for your help.

People are always demanding a micro stepper motor driver. It important for us due to some reason.
