Video of CNC machining a double sided part.

Nice part...
I noticed in the video you've got the plunge rate for the cutter set really low compared to the horizontal feedrate, so when the machine is ramping down it takes forever and doesn't do the cutter much good as the chipload is tiny. For this job, in the whole scheme of things it's not a big deal, but if you're cutting a harder material it could even cause the tool to break, so get into the habit of setting the plunge rate about the same as the feedrate (maybe a little less) so it doesn't slow down. So long as you don't forget to tell the software to do ramping it will work well.

Another vote to see a video of the alignment method please Ant!

Here's the video on 2 sided parts. Its pretty lacking and that's probably because I didn't plan anything before picking up my phone and recording. Hopefully its enough to give you the general gist of things though. If your still struggling PM me and I'll give you my number. Its easier to chat about this than it is record or type about it.

i used to do a lot of 2 sided machining get a look at meshcam its cheap and its great for this,and gives you the option to generate the code so it starts from the centre edge instead of the corners so two dowls down the centre instead of the 4,
nice work.

Cheers Ant, makes sense now. Going over what you wrote in post 14, it's a perfect description of what you've done in the video.

Have to say your router looks fantastic, well done on improving it. Also the process of machining a curved surface is so mesmerising. Trust me when my router's made, I'll probably be eating my dinner in front of it, watching parts getting machined.
