High Speed Spindle Mount 1

I’ve been working for the last week or so on a mount to hold an auxiliary high speed spindle on my mill.  I chose a Proxxon Micromot 50/EF tool, which is a fairly slim 12V handheld rotary tool (think Dremel).  I wanted something powerful enough to do high speed engraving, but probably not a lot ...

Totally Screwed

I received a big assortment of 18-8 stainless steel hardware from eBay, with a lot of useful sizes/threads.  It was a decent deal, given how expensive good quality hardware tends to be.  I’m sure I’ve got way too much of several things, and still lack things I need.  If you happen to see something on ...

New Workbench

With the help of my dad, I built a new workbench for the machine shop on Saturday.  I attached the top and notched and installed the lower shelf last night, and also applied the first coat of polyurethane to the MDF.  The bench is quite large – about 11 feet long by 2 feet deep.  ...

Engraving Test

Did an engraving test tonight with some new engraving bits that I got from this eBay seller.  Decent results, though I am plagued by the X3′s slow spindle speeds.  I tried an experiment of painting the engraved text and then backspraying the entire piece with flat black, to see the text through the 1/4″ polycarbonate.  ...

Opto Interrupter 101

It occurred to me that not everyone may have any idea what an opto interrupter is and does. Opto interrupters are small sensors, used to detect the presence or an absence of an object.  The sensors are typically U shaped, and contain an infrared LED and a phototransistor responsive in the infrared band.  Phototransistors are ...

Groove Homes

After more work than I anticipated making the Y homing sensor mounting block and making a bracket and sensor setup for the Z axis, tearing down half of the machine, rewiring, adjusting/loc-titing/rebolting, circuit hacking, and other general tomfoolery, the machine has functional homing capability! I ended up using the second block I had made when ...

Home Is Where You Hang Your Hat

Unfortunately, back in October, I discovered that my level of conversion kit for my mill did not include the hardware for home sensors for each axis.  Everything was there, but for a few small brackets and mounting blocks, and the actual optical sensors themselves.  I asked whether the company would simply send me the CAD ...

Pendant Links

So I don’t lose these links, here are some fancy advanced pendants that someone has implemented for EMC2, along with the underlying software necessary. I have already experimented a bit with hidcomp, trying out a USB gamepad to drive my mill around. HIDComp GenericHID Fancy Lathe Pendant

It’s Like Christmas

Here’s the result of a lot of small ebay auctions last week… Our office manager gave me quite a look when she walked in with no fewer than seven flat rate US Postal Service boxes for me today.  My goal is to avoid buying more cheap Chinese tooling, and seek out good deals on high ...

Shop Reorganization, Part I of XXIV

This weekend, I started the major effort of cleaning and reorganizing my basement on the “clean” (i.e. non-wood shop) side.  I decided to move my electronics lab bench around, and move the mill into the room which used to serve as my storage/electronics area.  After two days of work, I’ve got the mill set back ...
