    Re: emco pc mill 50 & similar

    Nevermind, I figured it out. The release lever is left-hand threaded and unscrews. I knew it was something simple. :rolleyes:

    Re: emco pc mill 50 & similar

    Hey all,

    Looking for a clue about how to remove the spindle motor from the headstock on an Emco PC Mill 50. I have the head off the mill and the back cover removed. It looks like I need to...
  3. Re: HSMWorks CAM and ProtoTrak Tool Offset Problems

    Yes that setting definitely matters. From what you describe it sounds like you want "wear" compensation, but I don't know if the post supports that (or really anything about the Prototrak at all). ...

    Re: Haas monitor

    This sort of thing annoys me to no end! It is ridiculously easy (and cheap) these days to setup a simple e-commerce site where you can show off and sell your stuff. People are so much more likely...

    Re: Center of circle location

    That's helpful if you've already placed your sketch entity, but not before then, which is what the OP is looking for.

    Re: Center of circle location

    Ahh, now this is interesting. You're making the assumption that you know exactly what the design should be (including dimensions and constraints) before you start drawing. If that's the case then...

    Re: Center of circle location

    But would it really? You would still have to go back and dimension everything after it's drawn.

    Fusion is slow at sketching but I don't think this is why. It's slow because the right click menu...
  8. Re: Turning A Model Into A Negative For Mold Applications

    What level of accuracy do you need (in numbers)? +/-0.005" is pretty doable with a caliper, and on geometric parts you can many times do even better. If you need more accuracy than that it will...
  9. Re: Turning A Model Into A Negative For Mold Applications

    You say this part is a piston seal? Does it look something like this?

    If so I don't think scanning is needed or even appropriate. Anyone that's good with a caliper should be able...

    Re: tool engagement angle

    Good question. There are lots of machinist calculators but I don't know if any of them calculate engagement angle. I know GWizard and HSMAdvisor for PC do.

    Re: tool engagement angle

    In Autodesk CAM there is no parameter for "tool engagement angle" specifically. Instead the adaptive tool paths use the "step over" value, which is then converted internally to an engagement angle. ...

    Re: More 2D toolpath selection issues

    Yeah it would definitely help to see the actual part, or at least a dummied up version. Fusion is supposed to be able to auto-select chains but it doesn't always work depending on the specific...
  13. Re: Setting tool length offsets without the wireless probe system

    Yes. The Haas control stores tool/work offsets and compensation parameters indefinitely (as long as the internal battery lasts anyway).

    Some of the more modern tool coatings are designed to be run at higher SFM and can actually wear faster if they are run too slow. But this is highly dependent on the situation so without more...

    Re: HSMExpress - simple task

    It is possible by using the trace tool path and a manually created line that puts the ball mill tangent to the face to cut. Something like this:

    Re: UCCNC Post Processor Issues

    With 3D surfacing tool paths you won't get arc fitting unless the paths are in one of the major planes (XY, XZ, YZ). It's not a Fusion problem, it's a gcode/machine control problem. Higher end...
  17. Re: Fusion 360 "Cutting" option using MACH3 mill generic post wont post!!!!

    It looks like your post processor is not setup for plasma/laser cutting. I've never tried it myself so I can't really be of much help. If you don't get any answers here try posting over on the...
  18. Re: HSMEXPRESS / Fusion 360 2D adaptive clearing struggles

    I get caught by the minimum ramp diameter sometimes too, even after years of using this software.

  19. Re: HSMEXPRESS / Fusion 360 2D adaptive clearing struggles

    Oh I see what the problem is. It's the minimum ramp diameter under the linking tab. It needs needs to be smaller to be able to enter into the slot.

  20. Re: HSMEXPRESS / Fusion 360 2D adaptive clearing struggles

    If you're having selection problems it could be model specific, so we would need to see the actual file. I just tried something similar to what you described and it worked. That doesn't mean there...

    The open/closed chain selection thing is a little funky until you figure it out. Maybe 95% of the time it works great but for really complicated selections it bogs down. Fortunately there is almost...

    That would be odd because it pretty much has to be larger to work. Can you post a screen shot of the error? I've never seen that one before.

    Re: Problems with Fusion 360 toolpaths

    Oh that's why, because the resulting arcs wouldn't be planar or helical. That's a limitation of the controller. (and possibly even G-code?) It's not the post.

    If you have smoothing turned (in Fusion) on then something is not right because that code has no arcs in it. My guess is that your post is ignoring it for some reason. What post are you using? It...

    Re: Pre HSM cutting speed

    With cutters that small you're going to run out of spindle speed long before axis speed is a problem, at least with the standard 7500RPM spindle.

    And I'm not convinced that running high feeds with...

    If you always reload every tool every time, then yes, the separate work offset method will add an extra step. But if you reuse just one tool, it's a wash. If you reuse two or more tools, it will...
