1/4" would be significantly better for such a job, but would recommend multiple passes. The deeper you go, the more issues you will have with tool heat and pulling the material out. The slot will...

I'm sure they could argue that a smaller local customer pool means that they have a higher overhead to support the product. But then again, if the prices wasn't so high then perhaps that wouldn't be...

I found the same issue with the pricing, which put me off it. The issue I discussed with them is that I'm a small company. I don't have an engineer that takes up the seat as a daily job. Rather...

Heya Humbug!!! Small world ;)

I use a Geckodrive G540

It has excellent performance for high speed stepper movement. I believe I have run a stepper up to 17 revolutions per second before with one.

Typically the higher the speed you run a stepper, the lower the torque. If run too high, it will stall. You can use a bigger stepper, higher voltage with current limiting or buy a good stepper...

I couldn't tell if the wobble was the bench, the camera or my screen playing back the video hahaa...

You can typically get around 4 to 5 revolutions per second with a stepper with a basic driver. To get faster, you need two things. The first... high voltage to overcome the inductance of the...

GREAT TO SEE!!!

Awesome work! What are you using for software at the moment?

I bought a Festool for extraction... extra cost, but definitely a fine addition. I wanted to get the dust deputy attachment from the US, but they cancelled my order (which they had quoted the day...

The amusing thing is... the masses want cheap, and the importers are always asking for cheap from China. So what does China produce? Cheap products. If we demanded quality and didn't buy cheap,...

I spent $7k all up, including delivery and spindle upgrade, on a CNC that does 900x600mm. I can do limited aluminium cutting with a 3mm endmill, cutting 3mm plate with 2 passes, but the gantry is no...

Yep... meant 900 to 1200mm/min.
You'd need a pretty fast machine to even rapid traverse 9000mm/min.

Usually I slot cut at slower speeds when cutting thin acrylic, i.e 3mm thick. Otherwise there...

The ideal thing is to cut at the correct feedrate. It will avoid the tip edge rubbing on the material and becoming blunt. But if you're taking really shallow cut passes, you'll only be using the...

I heard back from Cristina yesterday.

"I had quite a few responses from the forum. I'll let you know if I need any further help."

Sutton have a range of bull nose bits with their B0204 series. Radius of 0.3, 0.5, 1, 2mm depending on the bit.
8mm $45..$48
6mm $31..$35
4mm $25
(3mm and 5mm also in the range.

They have a...

He is in the western suburbs of Melbourne.

Sent him a PM ~2 days ago, but haven't had a reply yet.

That's a darn good read Rodney!!! I'm up to the 3rd page in the second link... 9 more pages to go :)

lucylucky... your website is not working and comes up with a suspended message.

Very nice find Nails!!!

The issues I've found with getting such information via email...
- Ask more than 2 questions and not all questions are answered.
- If the person replying doesn't know the answer, they'll never say...

To those Chinese manufacturers wanting to promote their products.... the BIGGEST problem a lot of buyers have is with finding detailed information about your laser cutters. Seeing youtubes of them...

I really like you idea of having 3 placement heads, and no nozzle changing system!
Quite practical.

I found a supplier for tooling board in Melbourne, Cheltenham. Axson Technologies.
The stock 3 densities, 0.65, 1.18 and 1.3. Sheet size is 1500x500mm. The 0.65 density was $325 for 50mm thick......

I'm interested also. Sent an email on Monday, but haven't heard back yet.

If you have a small offcut... I'd be happy to do a few different cuts/slots/pockets/contours and video it. I'm keen to...

That's pretty good!!!

The music had to be muted! The nozzle system looked very much like the Madell type. Hard to see with the quality, but even the fuse clips for nozzle holders appeared the same approach.

The...

Ahhh... I thought you bought the interface board off ebay. Not the whole CNC.

I just don't have information to work from to help you further. You might want to advise location and see if someone...

It's the interface board you bought of ebay that we need to know, so Mach3 can be configured to match. Stepper drivers, motor and CNC brand name otherwise are of no use.

Need to have the info on...

Well... on the grand scale of things, this little problem is nothing comparing to putting together something with parts. G540 is quite a good unit, and it's saving you more hurt than you realise. ...
