More Pictures

Here’s a better version of the CNC test, done with a small ball end mill so it looks right: Also, here’s the result of another one of the included G-Code files from EMC2.  Superficially it looks pretty neat, but it exposes some of the issues I’m currently contending with, like backlash and proper stepper configuration.  ...

It’s Alive! 2

Well, the part hasn’t yet arrived from Australia, despite the company shipping it out with all due speed.  Kudos to them for doing that, but the fact is it takes many days for something to get over here from Australia.  In the interim, I went at the suspect part with files and sandpaper and managed ...

Pictures of the Conversion (so far…)

Here are some photos of the conversion so far, mostly the tear-down and building up the Z axis. In other news, the kit manufacturers have supposedly shipped me a replacement part for the X ball nut holder… Hopefully it will arrive from Australia quickly.

Kit Installation Has Begun 1

Last night I finally was able to start the process of tearing down my milling machine and rebuilding it with the parts from the CNC kit.  I was able to complete the teardown and get all of the Z axis work done last night, with only one mishap.  In what is probably a very common ...

Kit Has Arrived!

The ProMiCA CNC kit has arrived!  Now just the significant task of putting it all together remains… Kit quality is quite high – part fit and finish looks good.  All of the aluminum parts are deburred and nicely media blasted.  The HDPE parts have a decent finish as well. I do need to track down ...

Three Cheers for Flat-Rate Postage Boxes

My linear power supply arrived today, and it’s big and heavy as I expected.  After poring over data sheets and doing more research and fretting and calculating, I decided to step down to a 48V supply for my stepper motor drives.  Based on the torque vs speed curves and the other specs of my motors, ...

Stepper Motors

The stepper motors have arrived! I went with the same brand that ProMiCA used in their kit, but the higher torque version. Still need to order my stepper drives – probably going with the bulletproof Gecko G203V.  I did briefly consider designing and building my own, but that wouldn’t be free either, and the point ...

Trigger Pulled 1

So I finally pulled the trigger on ordering the CNC conversion kit for my mill.  After a fair amount of internal debate trying to decide between the Deluxe kit from CNC Fusion and the MX3 kit from PROMiCA, I went with the nicer (and unfortunately pricier) PROMiCA kit.  For now I’ve just ordered the basic ...

DIY Steadicam Inspiration

There’s quite a bit of hobbyist activity making ripoffs of the Steadicam Merlin … This guy has a nice design and has done a lot of work perfecting his design.  I thought he had the state-of-the-art in DIY stabilisers, but then I ran across this video today… I’m blown away.  To be fair, the guy ...

Road Blogging Tech

On my adventuring blog, I’ve grown to enjoy posting GPS track logs and photos as well as text upon returning from a trip.  Since I was going to be on the road/water for a long period of time, I wanted a means of posting updates with the same rich content from the field – not ...
