CNC'd Loco Wheel & Earning Brownie Points
David Jupp:
I have no direct experience of either package that Phil used - I do know from my limited exposure to CAM (mainly Alibre CAM) that there may well be 'non-obvious' setting options that can make a big difference to the outcome.
It would be interesting to understand if the 'better' looking results with MeshCam are due to inherently better gcode generation, or just default settings (for something in the program) that suit this job better than those in Aspire. I.E. with 'equivalent settings' (not necessarily easy if the terminology doesn't match) would the results be similar in both packages?

Don't care what prog's been used. I left all that far behind, when I finished working for a living. :D
The first wheel's very nice. But, the second one's superb! :thumbup:
Well done Phil! :clap: :clap:

Hi David,
I don't have Aspire - the code was generated for me - so I can't really comment on why it didn't work out. I didn't mess about with the MeshCAM settings - I just installed it and it worked!
I'll experiment with the MeshCAM settings to see if I can speed everything up without cocking up the result too much.
I will probably end up buying Vectric Cut3d and then I can at least discuss the problems with Vectric. (I bought Cut2d and am very pleased with it.) Although MeshCAM seems such a bargain at the moment. Maybe I need both!
Alibre was recommended to me but it's cost rules it out.
Cheers.
Phil.
David Jupp:
Phil - I certainly wasn't recommending Alibre CAM (it's based on Mecsoft VisualMill). I don't have anything like enough experience to pass any kind of judgement on it. It may not be the most expensive, but certainly isn't bargain basement either.
Actually getting sufficient information to understand if a particular CAM package might be good for you or not seems to be quite tricky. The fact that your were easily able to get such a good result (apart from the minor bleb you highlighted) is a plus for MeshCam. Ease of use is probably more important than absolute capability for many hobbyists.
John Stevenson:
Phil,
send me the stl file and what tooling you wnat to use, speeds and feeds and I'll bung it thri Cut 3D and post you the code.
