    Re: My Chinese CNC Router Purchase 1325B

    They do list on their Ebay pages that you can contact them for TYD shipping prices. I think if I bought one I'd go that way. I'd really live to have a 5x10 sheet goods router, but I don't "need"...

    Re: Stuff made with CamBam

    Its a pretty simple project, but sometimes you gotta do what you gotta do.

    Replacing the plastic insert with one that won't break on a band saw table.

    No this isn't for my new saw. Its for...

    Ah, I see my LBS Shad Cutting Video Link got messed up. Here it is again.

    Re: Swapping Work Offsets On One Job

    Yep, so far looks good. Only issue is I forgot to set a style and tool for one operation in CAM. It wanted to drill the next set of holes with a tap. LOL. Fortunately I was standing there.

    Swapping Work Offsets On One Job

    Anybody do something like setup two parts in two vices on the mill and zero G54 to one and G55 to the other? Any issues with this with PathPilot. I can't imagine there should be, but...

    Poll: Re: How fast is your homemade CNC?

    P.S. My Hurco KMB1 while not home made was home retrofit by me. At one time I tested that 1000lb saddle and table at upto 450 IPM. LOL. I have it set at 150 now as its more than fast enough for...

    Poll: Re: How fast is your homemade CNC?

    Its a good idea to always have some safety margin in both voltage and current. Many drivers can handle their rated power for a short time, but continuously may damage them.

    Re: Linuxcnc to Mach3

    I am am sure you have to setup the spindle in the Smoothstepper plugin configuration.

    However, you said you were just changing over from LinuxCNC to Mach 3. Last time I checked Smooth Stepper...
  13. Re: tormach limitation, or am I doing something wrong?

    Did you put a collar on it so you could use it for height offset as well?
  14. Re: tormach limitation, or am I doing something wrong?

    You know in my previous comments I forgot to mention two things that may or may not be relevant.

    My comments don't take into account any inaccuracy in the clockwork mechanism. I would assume...
  15. Re: tormach limitation, or am I doing something wrong?

    That's 4 tenths off center. Whichever way you measure its off 4 tenths. Not 8 tenths. Unless I grossly misunderstood what you just wrote.

    Just like in a 4 jaw chuck in a lathe. Its exactly...
  16. Re: tormach limitation, or am I doing something wrong?

    Sure seems to indicate 4 tenths is the spec for the unit.

  17. Re: tormach limitation, or am I doing something wrong?

    Wait a minute. That's less than 4 tenths. Isn't that far better than the machine itself? Isn't anything less than 5 tenths considered pretty good for general machining?

    If the Haimer isn't...
  18. Re: Need help with g-codes for my CNC mill, I'm new and bad at it any help is appreci

    Active. No. Still accurately showing its relative position when you switch back to it. Yes. What's the point in having multiple work offsets if they do not remain accurate when you are using a...
  19. Re: tormach limitation, or am I doing something wrong?

    Would it be better to put the taster in a collet chuck tool holder instead of a set screw tool holder?
  20. Re: Need help with g-codes for my CNC mill, I'm new and bad at it any help is appreci

    You've got to be tweaking. Nobody is that pathological naturally.

    G53 does not trash the work offset. It has no negative affect. As you can see in this video the displayed work offset...
  21. Re: Need help with g-codes for my CNC mill, I'm new and bad at it any help is appreci

    Well there are certainly some machines that do not fully implement a Fanuc G-Code instruction set or that interpret it differently.

    However, you said "You are mistaken G53 does not change work...
  22. Re: tormach limitation, or am I doing something wrong?

    That's a great tip. Worthy of some reputation points.


    I've played with the idea of getting 3D taster, but I'm still using a tool height setter and an edge finder. For me its about price. I...
  23. Re: Need help with g-codes for my CNC mill, I'm new and bad at it any help is appreci

    P.S. Even if I am wrong about feedrate that doesn't change the fact that a G53 Z0 should always be safer than a G00 Z3.
  24. Re: Need help with g-codes for my CNC mill, I'm new and bad at it any help is appreci

    You are officially full of ****. I NEVER SAID IT DID. In fact stating I did and quoting where I said it didn't is just deficient at best.

  25. Re: Need help with g-codes for my CNC mill, I'm new and bad at it any help is appreci

    To the OP. Moving to a work offset coordinate may work if you are sure its within the machine work envelope. Moving to a machine coordinates will always work, unless you hit a vise. LOL When I do...
