First, I did not know that Carbide had a YouTube channel…so I guess my question is…instead of e-mailing Carbide 3D to ask for a video, why don’t they simply upload all the videos they have to YouTube? Short little videos like this one for installing and using the vice would be perfect. Again, having an unpacking video or how to use the flip jig would be perfect for new owners.
So to give you an update…using Winston Moy’s settings, I was able to easily cut out the square. But I have a few questions right off the top. I ran a second file to cut out a circle. I did not re-zero when I did the second file and it seems that there was no need to, since I had not moved the material. So my question is…I turned off the Nomad and I left the material in place…so when I turn the Nomad back on…will it “remember” where it last was or should I definitely re-zero it all over again?
Second, if my material is a square or a rectangle it’s easy to zero the XY at the bottom left corner…but what if my material is round? In other words…what if I want to cut a hole in an exact location on a real US quarter…do I need a jig of some sort?
Third, I secured my material to the table using the painters tape and super glue technique. I did cut slightly into the tape and some tape did get stuck on the bit. How important is it to remove ALL of the tape? Is there an easy way to “clean” bits?
Lastly, my third attempt was to do some text. However, the text appeared to be too small to be done with both the 1/8" bit (Carbides #102Z) and the 1/16" bit (Carbides 112Z). So it appears that I will need to use either a 1/32" or 1/64" bit. So two questions: Does anyone have any recommendations for the ZRN coated endmills in these sizes? A quick Google search only turned up ball end mills this size (not flat) and they were like $50 each (I think Carbide’s #112Z were like $30 for two, so that seems to be a big jump in price). And secondly, I have Winston’s speeds and feeds for both the #102Z and the #112Z (which obviously worked well)…if I try to use a 1/32 or 1/64" ZRN coated bit, is there a simple way to calculate feeds and speeds for these new sizes using his feeds and speeds for the larger bits?
Thanks for all your help so far!
