Re: 77th Birthday Present

Thanks Ray,
I HAD done a bit of research into slicers, 3D CAD programs and the like.  At one time, I could work in Auto-Cad, but that was many years back and I've forgotten most of what little I did know about that.

However, this printer is a SnapMaker (Chinese) brand we got off B & H Photo with all sorts of warranties on it.  Took 45 minutes to unpack, assemble, fire it up and calibrate (level the plate).  First print project was a simple flat dipole center insulator designed to have an SO-239 in the middle and was 100 percent infill for strength.  That one took about an hour and a half to print and printed without any issues at all.  They included a 1 kg spool of white PLA as the starter filament but it will work with ABS as well as several others I can't remember right now.  I've ordered some quarter kg spools of various PLA colors and a 1.5 kg spool of black ABS jut to have on hand.  Thingiverse has a whole bunch of ham radio projects including a spinner knob for my KX2 and THAT is going to be the priority project as soon as the black ABS gets here.  I might even print it in the white PLA as a test run to see just how long that one will take.

The only drawback on this printer is it's 4.9 x 4.9 x 4.9 inch print area, but for now I can live with that (famous last words, I know!)

2nd project was a nice little dual lever paddle (also from Thingiverse) that only took a bit over an hour and a half to make all 4 parts.  I still have to work out the paddle contacts and wire it up, but I do have the fixed ground contact (5mm x 2cm brass hex standoff) and solder lug in place - old ball point pen spring and all I need now is to make a through hole nut for each paddle (I have a Harbor Freight milling machine) and set up some adjustable contacts on each arm plus wire it all up.  Like you said, it's just starting - LOL.

I'd like to wish you a belated Happy Birthday!

Similar story - my wife bought me a 3D printer for my 80th birthday.  I will warn you - it becomes addictive.  My first  print was a power-pole adapter for my FT-817,  next a case for the raspberry PI doing fldigi duty.

Mine is only a printer so I have just had to learn solid design/ 3d cad stuff and the slicers to make the printer go.  You will probably be looking at several varieties of software for design and control of the engraver and CNC as well.

Then, if you are like me, you start lusting after bigger, faster, multi extruder, multi-color etc.  You have just started an interesting journey - enjoy!

Some of you that attended OzarkCon this year and spoke with me may have heard the story of my wonderful wife getting me a 3D printer for my birthday which was a day before OzarkCon started (April 4th).  It was supposed to be delivered today, but thanks to FedEx disregarding the specific delivery date, it was delivered Saturday while we were away.  Thanks to my neighbor who intercepted the FedEx driver and picked up the package for me, it was all safe and sound when we got home yesterday (Sunday) afternoon.

I got it all unpacked, assembled and running about 2:15 this afternoon and it's been running on a project (antenna center insulator) since I got it calibrated.  It's 3:20 Central right now and the insulator is about 75% printed.  The attached picture was taken just after it got the base firmly laid down at about 25% .  

Once I got everything unpacked I discovered that it actually came with 3 separate print heads.  The 3D filament printer, a 200 mW Laser engraving head and a 19000 RPM CNC carving head that can do wood, plastic, PC board material and light, non-ferrous metals with the right bit (included).

Folks, a 77th birthday present (besides still being alive and kicking) don't get too much better than this!  (Her birthday isn't until August 4th so I have lots of time yet to come up with something to top this.  Will be hard though!)
