Thanks for those links. I'll have a look over the weekend (sorry for the late reply - I've been away on holiday). Cheers :)

Thanks ger21. That makes sense. I'm a bit nervous to increase the feedrate etc in case it impacts too much on performance but I'll do some experimentation.
Thanks again for getting back to me. :)
Hi all,
I'm new to Aspire and I'm trying to carve a 3D owl out of MDF as a test.
I initially chose the "finishing" toolpath with a 1.5mm ball nose bit and created a toolpath. The software...
That's great thanks. You are perfectly correct of course. I wasn't thinking of all the different applications. I'll start with some ply and look at different clamping methods and go from there.

Hi John
Thanks for the info. I used some ally extruded stuff for the frame. I'll have a look for that 2080 stuff. I've not heard of that before.
You and Andrew are correct about the wood for...
Hi Andrew,
Thank you for taking the time to get back to me. Much appreciated.
What is the "norm" with these things? Do most people just use plywood and screw through their job and into the...
Hi all,
Last year my mate bought me an arduino for Christmas and I decided to have a go at building my own 3 axis CNC machine with it.
So far so good... I've got a machine that now drives on...
Hi Jono
I've currently got it set to 4.9A peak and 25,000 steps per rev. ** Disclaimer ** - I've not currently got the motors connected to the machine (because I've not built the machine yet - I'm...
Yep, that is exactly what was happening Jim. Thanks for the help. I managed to sort it last weekend with a bit of swearing, hair pulling and the help from another CNC forum.
Thanks again mate :-)
Hi all,
I'm just building my control panel for my CNC project. I'm a complete newbie to all this and I've come across a small problem.
I'm using an Arduino Mega as the "brain" of the...
Unfortunately I don't have access to a 3D printer. I was going to build one before I settled on a CNC instead. I'll have a hunt on flea-bay and I'm sure I'll pick something up. Just nice to know what...
Yes!! That's it. Brilliant ubergeekseven. Thanks :-)
Hi all,
I'm in the middle of building a CNC machine and I'm currently looking at putting together a vacuum system. This will comprise of the wife's Dyson, attached to a longer flexible pipe that...
That sounds like a similar set up to what I'm going to end up with. I'm glad to hear that you've been using it without any issues.
Thanks all for the great advice in this thread. :-)
What ratio of anti-freeze to distilled water do you use out of curiosity? Is it roughly the same mixture that you use in cars or less/more etc?
Thanks again :-)
Russ,
Really good info there. Thanks.
This is what I bought last night...
Aluminum 240mm Water Cooling cooled Row Heat Exchanger Radiator+Fan for CPU PC D | eBay
SC-300T 12V DC Wasserpumpe...
Wow! That's good to know.
Yesterday I ordered a small pump and radiator so I'll rig something up just in case but good to know that they don't need much cooling anyway.
I'm only going to be...
Thanks for the advice Rob. I've just been looking at a few YouTube videos that seem to be similar setups and this looks like the way to go.
Cheers :-)
Hi Gerry
Thanks for the help (again). So, does everyone just make home-made ones? Is there no simple commercial closed loop systems out there to just buy off the shelf that you know of?
If not,...
Thanks for the advice plcamp. I've not seen refrigerated pumps? Do you have a link to a recommended one?
I was going to attach a radiator/fan combo to this pump in order to cool the water/glycol?
Hi all,
I'm just in the process of building my cnc machine. I have bought a 3KW water cooled spindle and been hunting for a solution to cool it. I've seen lots of home-made solutions using PC...
Not thought about plastic but definitely going this route. Thanks for passing on your experience. I'll be looking into *which* spindle to get a bit further into the build but I'm definitely going...
Great advice there Wizard. Especially that last bit. I have to admit I've had a few sleepless nights with every part of the build, software, preparing the space for the machine etc all going around...
Ok thanks for the help. I'll wait until the rest of the machine is built and then do a bit of experimentation. Thanks again :--)
Thanks Gerry. I've change all the dip switches and changed the settings in LinuxCNC but this has created a couple more questions if you don't mind...
The stepper driver has the following info...
Yep, the first picture was just a 'stock' picture that I got from Google to just show the type of driver. The second pic is my actual driver.
I didn't notice the difference! Well spotted Gerry!! You...
Hi all,
I'm brand new to all this CNC stuff and so far loving it!
I've got NEMA 34 stepper motors, The name plate says 5.6A....
Yep, there's nothing wrong with your senses!!
I do work in a factory and program PLCs for a living so I'm knowledgeable enough about inverters / 3-phase supplies etc. But I've absolutely zero...
Great to know Gerry. I'm definitely going water-cooled so should be sorted. Thanks mate :-)
Thanks for the advice plcamp. Duly noted mate. I think I'm going to go for a variable speed spindle after all that I've read (and to your point about future needs).
Cheers :-)
