Re: Pausing/stopping the router
Thank you for that tip, Joe.
Well, here is an example for you and I haven't even got the look I want as yet. Size is 550mmx375mm

I got the look I want but look at the the cutting time, I definitely need to use Joe's tips

Re: Pausing/stopping the router
For those reading this thread and wondering about Bill's point about only 3D carving what you need to - for example if the 3D component is in the middle of a flat pocket - give this post a look - http://www.cncsharktalk.com/viewtopic.p ... =382#p1944.
Related to this with regard to pockets - I got a tip early on about pockets - create 2 toolpaths. Be aggressive in your depth of cut on the first one, and take it to 0.05 or so of the total depth. Then run one that starts at the depth of the 1st one, and removes that last 0.05

That's how I managed to cut the time down quite a bit.jeb2cav wrote:For those reading this thread and wondering about Bill's point about only 3D carving what you need to - for example if the 3D component is in the middle of a flat pocket - give this post a look - http://www.cncsharktalk.com/viewtopic.p ... =382#p1944.

However, there is no way you can reduce the time for 3D cuts so it will be nice to be able to let the machine have a rest. I am sure the router will appreciate that as much as my neighbours

If anyone is interested, I havee just put the 2 G-Codee files side by side in a Word document and marked them so it is easy to see how it is done.

Re: Pausing/stopping the router
Hi Wolffie,
My guess is you have this picture that you imported into Aspire and used the command to directly convert it into a 3D carving. What size ball end mill did you choose and what is the stepover?
You have a few other options to lower the carving time. Here's your picture with some tracings on it. Instead of one long 3D carving file you could break this up to a few smaller ones by using the tracing method Joe described for the full shape, then adding some vectors to break it down like in A shown on he picture.
One of the reasons it is taking so long to carve is the pebbled surface finish like in the B labeled area. If that's what you are going for then it will take a long time with a lot of up and down movements. You could use the smoothing tool in the sculpting menu to take that to a smoother surface which will cut faster. The other option is to trace the whole section B and create a 3D component. Both will carve faster then the pebbled finish.

Re: Pausing/stopping the router
It got too late for me last night, there was still a couple of hours left, so I waited until the router lifted for the next cut, hit pause, stopped the router, noted the line number, just in case and went to bed.ohiococonut wrote:Joe,
With what you're proposing wouldn't it be just as simple to hit the pause button and just shut the router off?
I had a long cut last night, (+10hrs) and had contemplated doing this but already had several hours cutting so I just let it run. I also had concerns about the stepper motors being able to maintain their position for several hours.
Hmmmmmm...............would it be possible to pause the cut, note the position of the router and stop cutting. Then edit the g-code to remove the lines before the paused state, re-position the router to where you initially stopped and start cutting again? That is what I was prepared to do, just in case we had a power cut or something You could also just leave the router where you paused it. Just thinking out loud here.
This morning it was still sitting at the same spot waiting for me to resume cutting, router had cooled down and was happy too.
Interesting observation, whilst the machine was paused, the timer kept counting, so when I came back this morning, it told me the machine had been running for 25+ hours although 11 of those was pause time
I have just ordered a water cooled spindle, I do not believe a router appreciates running for such a length of time plus they are so much quieter

It has to look as close as possible to the original artefact, hence the pebbled surface, which is actually gemstones.BillK wrote:Hi Wolffie,

I did pocket out all the smooth parts of the project, the rest is 3D components.
The length of the file doesn't really worry me, I was only wondering whether it was possible to pause the machine overnight, it is a rather large project, as large as the HD can handle.
I do not like to leave the machine unattended.
I did learn a few good tips in the replies

ps Joe
60 seconds are the same whether Imperial or metric
What does F2540.0 mean?
ps.ps
Never mind,I found out it means feed rate

Wolffie,
Where did you get the water cooled spindle from? How are you going to attach it to the shark?

I am going to make a new bracket in aluminium. The water cooler will be sitting by the base of the Shark.
