I have not tested the VFD readback, but I have solved the VFD not saving values issue.
PD001 (paramater lock) was set to 1 = lock
I changed it to "0" = unlock - and now parameters are saving!
...

Hi All,
Reading through some of the threads here some people seem to trade feed and speed data. Each cutter is unique, as is the material its used on. I recently bought some CMT upcut bits from...

Hi Commrades,
My CNC, 'RoboFang' is coming along nicely RoboFang.. Amazing how time flies! I though't I'd be all done in a few weeks. Almost 9 months later I'm still going!!

Anyway now I am...

AHA!!!!!!!!!! Yeah that'd be it.. my rods have been sitting open in my garage for over 3 maybe 4... hmmmm maybe 5 years..
Time to bake!

Here is the first of hopefully the entire build process.. in time lapse..

3 Days of Frame welding in 3 minutes.

RoboFang Time Lapse Part 1

I muffed up the second end frame brace though.....

Hi Dave,
Yeah I gave my end cover a whack with a piece of 4x2 after I had the bolts out and it dropped away. The wiring inside isn't as heavy as I expected so I guess this connector is up to the...

Hi,
I ended up using 3mm. I am weighing all the parts as they go together to get an idea of their mass. The leg welded to the long 100x100 support plus its 50x50mm brace across the bottom weighs in...

Hi Everyone,
I've spent the last few years lurking about this site and cnczone as well as joescnc.com, where I purchased plans. I have already built a little protoype cnc router.. a baby.. with a...

hmmm my cover isnt plastic. I'll take a photo and attach it later today. I am refering to the top of the spindle. What looks like steel, painted black.. The connector is mounted through it and the...

Hi Rod,
I just got a new chinese 2.2kw water cooled spindle.. I really really dont like the look of the audio grade 3 pin connector, to carry up to 2.2kW?? no way! So I want to swap it for something...

I bought a 'linear actuator' (maybe thats what you mean) which has precison ground hardened steel guides with an integral precision ballscrew supported on integral bearings with external tapped holes...

Finally I have some movement!

Here is a link to a page with a little clip.. nothing much.. but I'm pretty proud!...

As mentioned in another thread.. It turns out the cutter was never designed to be run at the 34,000 rpm it was running at. A lack of labelling on the cutter packaging was partially to blame.
So just...

Thanks everyone. So yes this is specifically for a cnc, using a trimmer router. Not for hand held operations.

Rodm I understand your logic of these cutters having limited relief. As always I'll...

Hi All,
I was at total tools today picking up a new makita N3701 1/4" trimming router. And asked the guy if I could see some of the ball end cutters behind the counter, he said they were no good for...

Hi Peda,
I've just recently had a bash at this stuff, with my CNC RoboTooth, made from plywood and bits of junk I've scrounged.
My suggestion is to just get started! I am absolutely besotted with...

Thanks again Rod.

I am using mach3, but once I setup my pc to dualboot into linux (which i know isnt difficult) I'll have a try at EMC2.

So I did a little reading on feed rate calc last night...

Even though its in a tangle of wires it is alive!
I did my first route last night with a 130watt Ozito dremel lookalike. I've been so focused on getting this thing moving in 3 axyceciss.. now I need...

Something funky is going on..

I followed the calibration in the settings window, but it didnt work.
i said move 10 units.
it moved 11 mm
i accept its settings.

I reset my ruler so its zero...

So the motor is getting pretty hot after 45 minutes of testing I wouldnt want to hold my hand on the motor body - its getting up near burning hot. I'll drop down to 500mA.
I tested the resistance of...

ahhh a 15 tooth drive with a 1 tooth per mm belt will give a 15mm travel per rev.. ?

Great I'll try that. I dont undertand what belt pitch has to do with motor travel though..

Hi,
I've got motion on my Y axis! But the tuning is out and I can't figure it out..

I have a stepper turning a 13mm dia toothed wheel, direct driving a toothed belt. The motor is attached to the...

Chris,
Your right. I just assembled my X-Axis bearing rods and trucks and it could be my sloppy joinery, but it is a bit skittish and prone to racking with just one truck. The sc20uu linear bearing...

I should have clarified. This first machine is to be used mainly with acrylic and a dremel. Just light cuts. And yes the Y side supports are a bit of a concern, but this'll be a learning testbed.
I...

Hi All,
cnczone is a nightmare to navigate, and being a Melburnian I thought I'd post my build log 'locally'. I will be implanting loads of links as I find many people forget that not everyone knows...

Ohh and those prices were from Moorabbin Steel.

For the benefit of other in the Eastern Suburbs of Melb my local steel merchant has the following options..

Can anyone comment on whether the bright mild will have a suitable finish and tolerance...

If you see him, tell him I'm looking for him!

Thanks.
There are some good prices in that web store!

Hi,
I got some 20mm dia sliding bearing carriages on eBay.
4pcs SC20UU linear ball bearing CNC Router XYZ Table on eBay (end time 04-Feb-10 21:51:17 GMT)

And am now on the hunt for a supplier...

Can't answer that myself. But take a read through the attachments I put in your other post.

Hi, I found the actual docs I was referring to over at cnczone.
This stuff was really helpful (to me) and I learned a thing or two.. like your steppers can be too big...

There are two files...

Just before you spend all your pocket money on your motors (then a suitable controller) you might like to run through this motor calculator which I found over at cnczone.

Free stepper/servo motor...

CFM = cubic feet per minute.

Sturdee and woodfolk, I have 2 queries. I've been thinking of buying a thicknesser. Whats the difference between a thicknesser and a drum sander? Assuming its just the amount of material able to be...

Thanks IanW. I guess its a case of "easier than it looks / or sounds" I have a friend how can lend me an arbortech wheel. Looks like fun actually.
I have some glue called 956 or 659 or something...

Ok, let me attach a pic of the profile I'd like to replicate. The issue I see is with the centre ridge - its fairly sharp and delicate looking. Also the wood I have in mind for this project is scrap...

Thanks for all the info. Looks largely like a manual job. Not sure if I have the skills to do this one - only one way to find out! Getstuckinuit!
I had heard that those sculpting blades for grinders...

How is that tractor seat shape formed in seats and rocking chairs. I've looked for a wide bullnose plunge router bit but can't see anything. Is this hows its done? I was thinking of using said bit to...

Do these actually work and who makes them? I can only find the Triton one for Australia.

Meanwhile back at the workshop..... Well done Sturdee.. Can I offer - an infeed roller could be made easily from a windscreen wiper motor directly coupled to a rubber roller (scrap from a...

So what does this jig look like. I assume a floating tenon is a tenon that goes in a mortice in the leg and a mortice in end grain of the rail - like a fat biscuit?


Looks like I have to keep...

Ok all this seems to make sense. Let me expand on my thinking. I selected the MJ over the HB due simply to the fact that is comes with a sliding table. I plan at least initialy to use the table to...

I'd appreciate it if someone could enlighten me on the benefits of a dado set. Im considering buying the Leda MJ2325 and now know that it wont take a dado set. If I ever have the need to slot is...

Im also tossing up the virtues of the TSC-10-HB // MJ-2325 10" saw's. It appears to me that the sliding table on the MJ looks good enough for my applications, and its cheaper. I made a table saw for...
