Re: some panels
Warren I am having some trouble to with mine. I have found for cutting out shapes that a feed rate of about 10mm/sec works well with a 2 or 3mm bit. The 3mm is better as it gets rid of the waste better. I broke mine last week and had to go back to 2mm until i could get a replacement. My router is a single speed unit and at 10mm/sec, there is no chattering on the edges. I also set the plunge rate at 10. It takes a little longer with the actual cutting but the results are pretty good. A quick sanding with 400 wet and dry and off the paint area.
My main concern is getting the panel flat so that the engraving is the same depth across the panel. On some of the ones todate, it starts off at 1mm on one side of the panel and then is not even touching the other side. Very frustrating at the moment. So i cam cutting the panels and painting them and while they are drying I am trying to sort out this uneven depth problem.
I am happy with the actual cut out shapes and sizes. Just gotta get it working for the engraving.Cheers

Re: some panels
Thanks for the tips... It would appear I need to either slow my feed rate or speed up my cut. My level is fairly good, but does taper on one corner. I just cut a few sacrifical table tops today while I was working on my MIP stand. I should be able to shim/adjust those to be fairly close.

Re: some panels
I can/will post all of my A320 cut files tonight. As was stated by flatland, you have to keep in mind that these are sort of like art in a way... each person's panels may be/are different. For instance, my panels are engraved and cut at the same time (so far), and the size of my panels is taken directly from the A320_paneles CAD file, so they will fit a sim with those dimensions best. That being said, it will be great to have a set of cut files for eveyone to draw from, and adjust as needed... probaby even better if we post the DXF drawing files as well.

Re: some panels
(original) (dxf) files, with a known scale, would be great.

Re: some panels
All I have are the seperated DXF and g-code files I made from the A320_Paneles.zip file. I originally was making test panels using hand-drawn files made from looking at pictures on cockpitsonic and othersites. My glare panels are made in one piece, with engraving and cutting done at the same time. I will post the EFIS and FCU files after I submit this post. I know they will not be what everyone wants, but they may be useful to someone.

Re: some panels
Hey Dave, I have a piece of MDF fixed to my table as a cutting block. I then get a large (20-25mm) flat router bit & shave the top of the block so it is perfectly the same distance from the router to the block if that makes sense. I first tried to fix my work to the block with fixings around the edges, but I wouldnt get a consistant level of engraving as sometimes the middle of the work might be slightly raised. I now stick my work down with double sided tape , find a tape that is not too sticky as ita a pain in the *** to get off. I also found that spraying a thin layer of polyurathane floor varnish, makes it come away from the block a bit eaiser. I use a 30° "V" point, PreciseBIT 2-flute Scoring / Engraving bit, 0.005in tip for my engraving, just scratching the paint off the surface with 2 passes..
Hope this helps you out a bit..

Re: some panels
Thanks for the tip guys... I will do exactly that. I also need to check the table etc and make sure everything is level as well.
I will let you know how i go.
As for dbl side tape. the plastic i buy has the sticky paper on each side. I cut the panels and then remove the paper. So i could remove the engraving side and paint. Then use the paperside to apply the dbl side tape which would come off with the paper.Cheers
Dave
