Yep, I’ve popped my 24 hour cut cherry! In fact did it 8 hours ago! Currently on 3.3m lines of g code.
Who else has done a 24 hour+ cut and is a real cnc man?:joker:
In 16 hours I will have popped my 2 day cherry!

Oh, my poor little machine.!! . . . Did I mention the warranty was 12mths or 3.5million lines of code or whichever comes first..:hysterical:Quote:

Well, a show-off who upstages me anyway :hysterical:
Looking forward to seeing the result, whatever it may be.

Double man. 2 days and counting...... Hope this cut finishes today as I’m off to Devon for 4 days tomorrow. If I’d have selected an appropriate sized bit I’d be long done by now :beaten:

Today I've been playing with a new clock design in Gearotic and CamBam. By doing some redrawing of the DXF import from one to the other and making the arcs arcs instead of polylines I've managed to get the number of lines of code for one part down from over 500 to about 50. What kind of 'man' does that make me?

PS Enjoy Devon, the weather must be becoming just about bearable by now.
Less of a man...... A real man blunders straight in with little thought, goes about things in an overly complex way with the wrong tools, then refuses to alter the plan and ploughs on regardless through sheer bloody mindedness. Come on now and "man up" and turn that 500 lines of code into 5000 :black_eyed:Quote:

That's quite easily done - just use trochoidal machining. I did a small job on Friday that involved some deepish slots in aluminium and tried doing it that way and managed to generate over 450,000 lines of code for cutting 650mm length of slot - but at least the cutter didn't snag :triumphant:Quote:

I live in Devon. Don't know that we want any "real men" disturbing our peace and quiet! And bragging about their shiny new machines. Mine still hasn't even been painted. Still, in our perpetually warm, dry, micro-climate, paint is for wimps.
I delivered one of those shiny new machines to Devon only a few weeks ago(Newton abbot), if I'd realized you were so near I'd called in with my HobKnobs..:yahoo:Quote:

Well, if you happen to be coming down again on one of the many warranty call-outs, give me a shout! I jest - you supply the hobnobs and I'll put the coffee on. No Yorkshire tea in this part of the world.
Small world I sold and delivered my Warco WM18 to a guy in Totnes.Quote:

Biggest problem with machines in this part of the world is that you need lots of packing under one side as everything is built on the side of a hill.
I think you have the description about right!Quote:

Perhaps Devon won't be so good if they are not civilised enough to have Yorkshire Tea. We drink Yorkshire Tea here in Tasmania, though I haven't yet seen a packet of HobNobs.

So, 2 days and 17 hours.... 8.6m lines of code later.... I have something fairly presentable made from the sink cutout of my worktop. A bit of minor sanding remedy and some antique stain and I'll have a map off a pirate ship!
I've learned a few lessons.
Use the correct tool for the job. Not a 0.25mm tapered ball nose end mill for something massive when you could have atleast doubled the size and greatly reduced cut time.
Tools wear out. Especially tiny tools. Noticed a small step appearing in the cut. After a couple of hours pondering the cause, I activated feed hold to inspect the bit. Bloody tip had worn or snapped off. Just a tiny bit but noticeable.
Have more than one of each bit. Thankfully I did have 2 of the same bit. So I could just swap bits and carry on without to much bother.
Multiday cuts are a faff. Had me checking all the time, going to bed at midnight and setting my alarm for 6am to get it cutting again. This was mainly down to my time constraint of leaving for a holiday today. Still, being a novice, this did consume me.
A bucket of water gets hot. Now I initially was worried and stuck some ice packs in it. This cooled it down for about an hour which I then realised would become rather tedious doing constantly for 3 days. So I took a deep breath, got the kids IR thermometer and measured the spindle temp. Stayed pretty constant at 35-40C. Realised this was unlikely to be dangerous and relaxed.
Models can be a bit ropey when you make them big. There are some edges that have some marks/artifacts that can not be from tooling. Almost diagonal hatching type lines. I'm assuming this is in the model when scaled up. Not sure how models are made......
Bigger is better. A faff it was, but I can't wait to stain and age it up. Its going to look epic.

Wow that looks pretty tasty! Where did the model come from - did you make it yourself?
I'd love to say I made the model - But alas no. Purchased off Etsy for £2.38!
Actually, I have very few issues with machines so warranty call-out makes a nice change sometimes, esp if it's in Devon or Cornwall.Quote:
