    Re: Lofting the Fuselage

    If the image I am trying to post actually appears,you will see the transverse sections and you will need to create the equivalent for your project.Where there is a definite change of character,each...

    Re: Epoxy resin machining

    I think it will be very difficult to get a good outcome with epoxy if the deep draw process involves forming metal.If it involves forming ABS or similar plastics over a machined form there are...

    Re: CNC 6040 - issue with working

    A picture of the machine might have been useful.One way of learning more is to run the same sequences in the opposite direction and to compare the results.I would be surprised if it is the controller...

    Re: CNC Profile Cutting Topo Model

    You will almost certainly need to find a long enough tool and it will need to either be waisted or to have a shank diameter that is less than the cutting diameter or the friction will do nasty things...

    Re: The Best Software for 6040 CNC Machine

    Rhino is excellent and not that hard to learn.Gcode can be generated by all sorts of software and there are free programs out there that will create useable code from a dxf file and inputs regarding...

    Re: The Best Software for 6040 CNC Machine

    I'm not a Mastercam distributor and it would be more than capable of running a 6040 machine,but for the same cash outlay,or less, you could buy an 8'X4' machine with more up to date control software...

    Re: The Best Software for 6040 CNC Machine

    I think you need to study the topic a bit more deeply.Mastercam can be used to produce the code but the machine will need Mach 3 or something similar to convert that code into motion.I do find it a...

    Re: CNC Machining Electric Guitar Body (UK)

    I'm not in that kind of business but would offer a couple of comments.First of all,have you seen the very realistic metallic finishes that can be applied to wood?Second,are there safety aspects to...

    Re: 5 axis trunnion issues

    I thought this thread had faded away.I would suggest that one fix might be to look for the retract sequences in the program that accompany the unwinding of the C axis and use Wordpad or similar to...

    Re: 5x10 Chinese Router with Issues

    I think you need to go all round the machine to identify the source of the flexing as it may have it's origins in a place that you might not suspect.To my eyes,the spindle mounting bracket is less...

    I'd be interested in seeing a model of the proposed machine,with notes to explain how it all works.
  20. Re: How long does it take to learn to feed G-code through a machine?

    It is a good thing to have an understanding of the most used expressions but even so,few people sit at a controller typing in Gcode these days.Conversational controllers or CAM software have just...
