Re: G0678 CNC Conversion Build Log

BC, I'd love to tell ya'all that I've been busy making parts but it just aint so! :cry: Just about the time I got this machine running I discovered I had moisture in my finished basement. So I'm in overdrive trying to get to the cause and find a solution before it ruins some very nice custom built c...

Re: Hobbyist Hardness scale

From Earlgo: How about "harder than trying to get rid of the #$*@@! popup that claims to be MS support and your computer is infected, etc, etc". Does one of you computer gurus have a solution? Happily never happens on this forum. These happen to me when I am in my AT&T mail system. These are not vir...

Re: G0678 CNC Conversion Build Log

I gathered up all the courage I could find and I made my first actual part: This plate mounts over the left servo motor and will hold TTS tool holders. It came out just like I drew it. What a concept! :D 0326181132 (2).jpg I also made a couple of short videos of the run! https://youtu.be/6ag1OWwQmik...

Test Run:

Not much of a part but it shows how I set tools without having to have a lot of Z travel. This method is pretty much fool proof and I can use tools as long or short as I need.

Re: Threading without the end groove

I actually remember it by looking at the way it approaches the part to make the cut. From the right is a right handed tool. (even though you are moving left to make the cut) I wasn't asking about how to hand a tool, I was asking for clarity so other readers would not be confused. Harold did a great ...

Re: Threading without the end groove

I'm making reference to the side near the chuck, which, when held according to the method used to hand a cutter, is the right side. I probably should have made that clear. Thanks for posting the explanation so the newer members aren't confused. The tool hand thing is a bit confusing at first. Dave C.

Re: Threading without the end groove

Make sure there's enough clearance on the right hand side of the tool to achieve full depth without bumping the shoulder. I grind my threading tools offset, for that reason. Harold, did you mean right side? If I am threading toward the chuck I'd want my tool offset with the tip more toward the chuc...

Re: bandwidth

Actually Spro, Computers today do lots of things that have nothing to do with harmful data being downloaded to your computer. For example Win 10 will try to defrag your drive from time to time without you even being aware of it going on. This is supposed to be a "convenience" or a service for those ...

Re: G0678 CNC Conversion Build Log

Just some FYI stuff: I got the last of the parts in for the Z axis, tuned the servo, tested the stroke with a DTI and I'm pretty good for now. The encoder I bought from Automation Direct was throwing Quadrature errors so it has been sent back for a replacement. So I can't do any rigid tapping until ...

Re: G0678 CNC Conversion Build Log

Progress Report: I had to wait almost 30 days to get the timing pulleys for the Z axis and the Spindle Encoder but they came yesterday. So I've been busy toady fitting pulleys to shafts. I've got the Z axis all done except for the belt and it is on the way. Z Axis Cover is done, encoder pulley is at...

Re: Building a CNC router

It is a learning experience. I am retired so time is not too much of a factor. I'm right there with you Mr. Ron! I could have bought a Tormach PCNC100 for about the same money as I will have in this mill project I'm working on but it was never about just getting a CNC mill, it was about making some...
