Hardwood gives a nice crisp pattern, the bearing caps are beech and the bits posted yesterday maple.

Joining in, I’m in the process of recomissioning a KX3 that’s stood for 5-ish years due to life, dead computers, changing jobs and the law of sod. The machine was bought from arceuro about 8 years ago, it went on to near -as-damnit play for itself in the first year with a job engraving room number plates I obtained through a colleague at my then employer. It then was used until a major reorganisation of the garage lead to it being temporarily decommissioned, then it’s PC died when attempted recommissioning, I changed jobs and for a while had no time or energy to sort it. That was about 5 years ago, Since then due to life and a lack of time, it’s sat, becoming more buried in random workshop crap. Then, along came Covid-19 and furlough.

So, I’ve obtained a new PC from my tame IT man. The current challenge is connecting the beast to the PC, following a lot of googling and research I’m going with a UC100 motion controller to (hopefully) make it connect with a USB. If that doesn’t work, it’s plan B. I’ve spent a lot of furlough learning fusion360, so watch this space.

let us know how you get on, I'm sure as computers die and ones with parallel port and older operating system become harder to find others may be in the same boat. Mine was one or the USB ones which helps.

It’s started well, following a lot of research and reading last night (guess who until yesterday didn’t know Arc didn’t sell the KX3 any more) and a very useful and downright impressive phone call to Arc this morning, I’m making progress. Just emailed Mach support about the licence to unlock the software (because I’m reinstalling it on a new PC, and the last registration was 4 computers/tablets and 3 email addresses ago). DPD should deliver the UC100 today, so it’s all progress in an upward direction.

Gawd, I can’t half get a lot done when I didn’t have to go to work...

Jason, regarding older computers and parallel ports. Parallel port cards are available and not expensive. Older computers can be refurbished to keep them going for many years more. In my experience the main problems are the electrolytic capacitors. These can be readily changed, but do use quality top tier makes with low ESR (Badcaps forum has loads of info and help). I change the caps on both the motherboard and the power supply. I have done this precisely because I want to have older pcs with parallel ports available for some cnc experimentation and or with very specific software. I realise not everybody wishes to get into component level electronics (and switch mode power supplies can be quite a rabbit hole to go down) or has the equipment but it is a way that works for me.

Owain - Have a look at PlanetCNC, I am really impressed so far on my Orac conversion and will move my KX3 to use it in due course.

Right, the UC100 has landed! Just need some time and to find the WiFi dongle to allow the pc to be (briefly) connected to the internet and we’re away. Andrew, thanks for the recommendation, if anyone else has suggestions for suitable that they’ve used (ideally on the KX3) then feel free to shout. I’m not wedded to Mach3, it’s just what I know and at the moment the major issue is recommissioning the machine and getting it to talk to the computer.

It would appear that the 'Steep and Shallow' 3d machining strategy in Fusion 360 is no longer free. crying 2

I notice that the Axminster versions of the KX1 and KX3 have Ethernet interfaces, I guess that is yet another version of controller board. Anyone know which one?

Regards

They have the Siemans control systems, hence the S at the end of the name.

We have progress! For anyone who has one of the older parallel port connection machines and doesn’t want to spend time resurecting old pc’s, having downloaded the driver (link on the CNC4You website, also where I purchased the UC100 from, on the basis of a) a UK supplier and b) a very prompt reply to emails) I’ve got the beast moving in all three axes on command in the correct directions via USB onto a PC running windows 8. Had to go through the ports and pins menu in Mach3 and reset them as per the settings in the KX3 manual, but apart from that, no issues to report.

I had originally said that I would draw up the flywheel for Graham Corry's 1/3rd scale Brayton Readymotor with the intent that he would get patterns 3D printed but costings were coming in quite high and he did not get much joy looking for someone who could do a one use CNC router cut foam pattern. So I said leave it with me and I will see what I can do.

At just under 400mm diameter I would not stand a chance of cutting it in one on the KX3 but did think about cutting the spoke area within the rim which would still have entailed doing it in 3 sections but not easy to accurately reposition between cuts. Another option was to make individual half spokes that could be built into a separate rim and that is what I went with.

First most of the pattern was cut away in Alibre to leave a single spoke with a 60degree segment of the hub and the fillets where the spoke joins the rim.

I used F360 to do the CAM and this was the first time I had drawn the stock rather than just letting the program suggest a cube it would fit into which allowed me to orientate the stock to the best position to suit the spoke shape and keep the overall size as small as possible to save machining time.

The stock was glued to a piece of MDF which in turn was held in the vice. I put a layer of copy paper between the two glued surfaces which makes it quite easy to separate the two as the paper just delaminates with a tap of a chisel on the joint line. This is the job straight off the machine

And after separating from the holding block. really happy with the finish which hardly needs any sanding, I set a small amount of backlash compensation to the Z=axis and that seems to have cured the marks I was getting in the previous parts cut using "steep and Shallow"

Before cleaning up the machine from cutting the 11 remaining spokes there was one other little item that I have had drawn out for a while. Originally intended to cut from some wood grain UPVC facia so that the lettering showed up white on the darker material but did not have any off cuts wide enough so I decided to make it from some 6mm melamine coated MDF.

Pleased with how it turned out particularly the engraving as it was the first time I had tried that and pleased with the "square" ends to the numbers rather than rounded that you often see, F360 works out the magic and lifts the 90deg vee tool at the ends though it did have a strange way of doing the rounded parts of the numbers such as 6 & 9 first?

I actually mucked up the first one having also entered the 5000rpm spindle speed as the feed rate giving 5000mm/min so the order of cutting is not really right. It should have been hole with the 6mm cutter then engrave and chamfer with the 90deg chamfer mill. Now I can get rid of the wooden rack the original 1-10 set cam in and the boxes from the ARC half mm and imperial ones.

Very neat Jason, I can see you will be doing brass engine nameplates next, should be good for that shouldn't it.

Yes it's a possibility though that would tend to mostly be raised letters and a lot smaller font than I used on the rack which need small dia (at the end) cutters and ideally a faster spindle if the job is not going to take ages to do.

I made these for a Tich for a member here (though he painted them). They are about 75 x 25 mm, with a 1mm cutter at 5000 rpm in brass. I didn't break a single cutter, but it did take a long time! (Photo by the loco owner.)

I've not tried engraving in Fusion 360, but it seems that you've VCarved the numbers. It's a very handy tool to have for making pro-looking nameplates & what have you.

Yes I think that s the name for it. Quick capture of the tool cutting the number "1" slowed right down and blown up a lot, you can see how the tool ramps into the job following one corner and then squares up the other before moving along to the next. The letters were drawn with straight sides cut 1mm deep so no need to taper them at the design stage.

I'm looking at a job that's just come in to make an embossing stamp to recreate an old "Leatheries" bicycle saddle.

I'll certainly need to use a VCarve strategy to give the right form to the letters and other shapes.

Martin.
