Here's some useful setup information for Haunyang VFD that I've collected and collated whilst on my internet travels.

NOTE: Always check these settings are applicable to your Haunyang VFD as there...

This one is cheaper.
As far as I can see it's just luck with the bearings. The sellers on ali-express will discuss them however, so it's possible to get better ones but you do pay for it. I got my...

The 2.2Kw model is 80mm dia. It varies for the others.

As for Spindle mount options your looking at making your own really. You can get them from places like ebay US and various CNC retailers over...

Wrote this then realised I completely missed the point. There are plenty of readily available designs for making a cyclone, so I'd just do that.

[It's difficult to get standard vacuum cleaners to...

Its quite well hidden on their site, the link is here: ALDI - Hurry While Stocks Last - Limited Availability Price quoted as £15.99, you had a result there! :-)

There's some talk over at...

This one is also useful: http://www.vortextool.com/images/chipLoadChart.pdf And gives the formula for using chip loads... at least as a starter for 10...

This a is a small chart to help with those of us that are doing lighter work. Always wondering what chip load to use so this may help.

The vertical plate on the back of the Z axis (to which the Y axis ballscrew is attached) is trapped between the small top and bottom plates. This means it needs to be machined accurately to ensure...

The distance measured parallel to the Y-axis between the spindle and the Y-axis ballnut/screw is currently quite large. This will cause the cutter to deflect parallel to Y as the rails offer little...

Cut it in one go. . . . I do it by first cutting the round rail using 1mm thin disc in the angle grinder, cuts like hot knife thru butter then finish Alu base using mechanical hacksaw but hand held...

AW is good like Jonathan says but you really only need tool plate quality in just a few key places, like the Z Axis front/rear plates or for the Bed etc.

Things like gantry sides and general end...

Aluminium warehouse has tooling plate which may be cheaper? It's on the website in the same place I linked to earlier. They call it EcoCast.

I spent some time experimenting with cutting MDF templates for the best layback and what you see in the pics is the outcome. I found it gives the best balance and can still be got from 12" x 3/4"...

I can make a few suggestions that you might consider having built a few machines very similiar for the same job and actually have one part built which I just don't seem to find time to finish.! I'll...

Best to go for 20 on the long axis with 16 on the rest.

From Chai / linearmotionbearings2008 on ebay?



I definitely wouldn't use any less than 20mm rails. I currently have 20mm rails on Y/Z (900/400mm) and 25mm rails on X (2000mm). The 25mm rails do...

i would say it is worth splashing the extra cash..... however you need to do some lurking on ebay and bide your time so that your NOT spending £800 on rails n bearings... they do come up cheep from...

Interesting that you consider the pitch error causing crabbing of the gantry to be a significant error. For C7 ballscrews the error is up to 0.05mm per 300mm, and it's not simply cumilative - it is...

eBay ... but you'll have to wait for the right place. Are you sure you need THK as unless it's some amazingly accurate machine from what I've heard the other brands (Hiwin, NSK etc) are fine for what...

On the subject of clamping and t-slots. A cheaper and easier to replace solution is a sheet of 12mm MDF, drilled out with 5mm or 6mm holes in a grid (easy job for the CNC machine!), then hammer in...

For those interested, I thought I'd post my updated stiffness calculation spreadsheet in a new post. This spreadsheet is intended for a typical moving gantry cnc routing machine, and may help with...

I recently cut some aluminium profile/extrusion.

I used a Chop/Mitre Saw to cut it, the thing is you can use a Wood Blade to cut Aluminium, you will need to make sure the blade has TCT teeth on it...
