Hi Barrie

Your lessons have paid off big time😁😁😁😁test two 3.5 mm balsawood cut on my K40. Power 60 speed 70mm/s one pass cut straight through. Note the magnetic locking system works a treat. See youtube link for video, happy days and really no doubt that i have the laser cutter i need to do the job, keep an eye out for the next test🤣🤣🤣🤣

Not only is that fast cutting it is also very good quality, you have a nice finish on the wood not over burnt in any way.

Well done.

Regards

Barrie

I am so thrilled with the results, it helps when you pay attention to people in the know. When is the course i want to know more🤣🤣🤣🤣 the lack is probably down to the air assist pump you recommend, sorry for been a copy cat 👍👍👍👍

Just before the 'Wu Flu' crisis I was in some reasonably advanced discussions with Manny Williamson to do some courses at Buckminster National aeromodelling centre. There are some suitable classrooms there.

During the lock down I have thought a lot about the course project, I am thinking of 1 day on laser cutting and 1 day on 3D printing, probably over the same weekend and then people could have the choice of attending either or both courses.

There would be machines on hand for both days, I done something very simple on 3D printing there already so know the layout etc.

However at the moment the 'Wu Flu' has put the brakes on everything, my guess is that maybe something can happen later in the year pending lifting of restrictions.

How does this sound to you?

Regards

Barrie

I would be very interested in attending such a course Barrie, if you can get one going. I will keep an eye on the BMFA mag for an advert later in the year.

As far as cnc router kits for the 3D Printerless goes there are many offerings from the usual Chinese suppliers....but beware of going for the cheaper ones. When you start introducing a load on the gantry, like when you are routing as opposed to just lugging a laser head around, you will need bigger, more powerful stepper motors, only the biggest of the NEMA17's are powerful enough to be *sure* you are not going to lose steps, you really need to be looking at NEMA24's, which means bigger discrete stepper motor drivers too. All that starts to add up! If you are going to be happy with very low feed rates in very soft materials then Geoff's solution will work, I also have the same setup. Also beware of the small 'PCB routers' with a mabuchi 550 motor and a tiny working bed size, they are really only good for PCB making.

Much like buying a K40 over a eleksmaker LED 3.5W laser, you have to spend the cash to get something with sufficient capabilities to satisfy your needs - both now and in the future.
