Hey Andy, just doing some research on the reprap controllers here and I stumbled on your min644p page – excellent stuff.
I’m going to get the Dremel out and get started tonight.
Yeah thats the board, chip and xtal I gave you last week. Most excellent. I have spent the last couple of days collecting the .STL file together for a mini-mendel and sending them off for printing. So in a week or so hopefully I can be following you. Nophead is doing the printing.
I’m thinking this board would be great for ArtBot version 3. Gotta make another.
BTW the pads are for 0.8mm holes, right? Just bought some new ones – mine were all snapped from the last time I tried this malarky.
If you are making another download and print the layouts from my blog/docs on line as I increased the pad sizes.
I drilled my boards with .6 for the component leads and .8 for the pin strips. May need to go a little larger than .8 depends on how well the holes line up.
Yeah I go through board drills at a fast rate. Having a mini drill press thingy makes them last a little longer. Drilling by hand you are too likely to change the angle during the drilling and snap the bit.
