    Re: Computer Science Assignment Help

    So we have a thread about buying essays to claim as your own work so you can be given marks you didn't earn and basically cheat your way to a qualification?

    Re: Why did this happen?

    If it happens again with a new collet,you may have hit upon a combination of spindle speed and feed that is causing a destructive harmonic oscillation. There is almost certainly some sophisticated...

    Re: My first CNC build

    I suspect the biggest potential problem with the proposed design is the single lead screw in the centre of the gantry.There have been several instances on this forum of such gantries skewing under...

    Re: Help understanding stepper motor behavior

    From the images the 14mm pitch looks like quite a large multiple of the diameter.With such a coarse pitch in relation to the diameter it only needs a tiny discrepancy in the amount of rotation for a...

    Re: Help understanding stepper motor behavior

    May we have the chance to view the lead screws?I'm guessing that with Nema 17's involved they aren't large and may not be ballscrews.I would expect a stepper to complete one revolution when the code...
  6. Re: Please help.Cant figure out how to cut out a tile with shallow release angle on s

    I don't know Artcam at all,but I have machined a good number of moulds for GRP and carbon.If you are machining the mould with that number of sharp corners there will be a lot of hand finishing as you...

    Once you have taken off the head of the last bolts what might happen to the part that is freed?Consider very carefully the possibility that a large and heavy piece of machinery might land on your...
  8. Re: Feedrate and RPM for plywood 6mm compression bit

    I agree that an upcut will create splinters and that is why I suggested a straight tool,by which I mean one with no twist.If you are running a compression tool at very shallow dop it is acting as an...

    Re: Vetric Aspire nose dive on Z Axis

    I believe the entirely spurious challenge involved a 28 foot radius.The OP has a rather individual way of asking for advice and then acting on it.I have to wonder if there are other background issues...
  10. Re: Feedrate and RPM for plywood 6mm compression bit

    1.3mm pass depth with a compression bit seems to be a pointless use of the tool as it will be acting as an upcut only. It also looks like an ambitious feed rate for a fairly tiny spindle-the fact...

    Re: Looking for honest opinions

    I don't currently have a laser,but it might be something for the future.I do have a growing amount of experience with LinuxCNC.I would be interested in learning a bit more about the aspects of Mach4...

    Re: UCCNC and Linux

    Have you tried running your CAD/CAM program of choice under Wine?As I may have mentioned,I use Freecad on my machine control computer which uses LinuxCNC and as it isn't too easy to add Freecad to...
  14. Re: Lost drill hole size accuracy in drilling operations

    I suspect the original batch of drill bits were slightly oversize as I wouldn't expect to be able to insert a 6mm pin in a hole produced by a 6mm drill bit and to expect a number of them to match...

    Re: UCCNC and Linux

    I have to agree.I moved to Linux about 12 years ago but I still find it necessary to have an old Win 7 box to update the satnav for the car as Garmin only works with Windows.It is quite noticeably...

    Re: unrolling a circle

    You might need to visit a sheet metal forum for advice on where the neutral axis of a rolled cylinder is likely to be if the accuracy is really important. Its also going to take some fairly serious...

    Re: Vetric Aspire nose dive on Z Axis

    I am guessing that the Mastercam training provider was milking the system in a big way if it took five months to cover the system.I did the training for 5 axis machining in two bursts of two high...

    Re: Vetric Aspire nose dive on Z Axis

    If I had a choice of Mastercam or Aspire I wouldn't be using Aspire very often.Either is capable of doing the job and both can simulate well.In the settings options of Aspire there is a choice of...

    Re: UCCNC and Linux

    I tried a quick search and found nothing to suggest that here might be a Linux version.I would suggest,as others have,that you might try downloading LinuxCNC and giving it a trial as a live...

    Re: UCCNC and Linux

    Before doing anything it might be worth downloading a Linux distro that will run live.Once up and running you can try installing UCCNC under Wine.If it works-problem solved.If not you haven't lost...
  24. Re: Mach3 no longer works in Windows 10 as of version 1803

    I don't have AutoSketch and consequently wouldn't know the answer.If you have it and could download an iso image of a Linux distro that will run live,you may be in a position to tell us if it does...
  25. Re: Mach3 no longer works in Windows 10 as of version 1803

    I'm fairly sure you can run Linux in a virtual machine.Rather than doing so I would partition the hard drive and set up the system for dual booting to ease the load on resources.You don't need a huge...
