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 ...

Symphony of Steppers 3

I wired up all three axes today, and also hooked up the super high quality 200V DMM module that I picked up on eBay direct from China. Here it is whirring away to the dulcet tones of Andrew Bird from my shop speakers.  It’s running the torus demo from the EMC2 live CD.

Signs of Life 3

Finally had some time this weekend to hook up a stepper drive, stepper motor, power supply, and a PC to see if EMC2 would move a motor.  I’m pleased to report success!  I just wired up a single axis for now, but it demonstrates that EMC2 is properly generating step and direction pulses out of ...

Gecko Infestation 2

The Gecko stepper motor drivers have arrived, along with my cheap and cheerful dual PCI parallel port card.  There should be enough stuff here to make some motors spin, though I’m not going to have any time to play with the new toys until next week.

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 ...
