Calling it a day.
Thanks everyone for your help.

This is not correct. The software is perfectly capable of both importing and exporting G & M codes.

I've now set the parport mode to EPP, and the address in the config to 0x378, and at least I no longer get the pop 'error' window.
However, I'm no further forward in getting any response from the...

I've just had a brain wave - checked the parport mode in the bios, and discovered the default setting for this pc is PS/2.
Now faced with decision - EPP or ECP ?
EPP gives 2 addresses - 378h or...

joeaverage.

Casein is useful in bulk mouldings, but in thin sections, ie 1mm and less its lack of stiffness becomes an issue.

Hi Pete,
It was coming across the original work done at the Max...

Update

I'm now developing my own version of a material produced in Germany in 2019.
When my experiments produce some results(still building my own chemistry bench equipment ! ), I'll post the...

By chance (?) I went to my own profile, and looking at the list of settings, saw at the bottom 'Attachments'.
Clicked on that, and went down to the date that I was having the original problems, and...

0v ? Good point Peter. I'll power up the controller, and measure the voltage on that 'enable' pin. If it's 'high', then I'll try grounding it, if it's 'low', I'll try +5v.
How does that sound ?...

Peter, While there appears to be no separate 'enable' switch, either on the outside of the case or on the pcb, I take your point about the software needing to be running.
As I'm still at the stage...

Peter - thanks for that suggestion, I'll have to have a closer look at the pcb. I've sent out a message to a guy that I might have supplied a cct diagram to, about 15 years ago ! No idea what...

Hi Awerby,
Thank you for your reply.

Spoiler alert.
Please don't take this personally, but you have just triggered an 85-year old's rant.

As I have chosen to post this in the 'Epoxy-granite'...

Not wishing to upset anyone here, I stopped using ivory, a high-end traditional material for fan makers, many years ago.

However, never having found a good alternative, and my early life...

This is even later ! Now in USA with a manual mat cutter that I built.
Much water under the bridge, but if my profile has been updated correctly, I'm now in Corinth, MS.

Just to update this thread, and to miss-quote Jane Austen, "Dear reader, I married her".
Now living out my days in Mississippi, fan making, but have most of the parts of my cnc build, so going to...

Good grief. So this is what I find, when after an absence of a couple of years, I come by to say Hi to anyone who has a long memory.
Still happy in Mississippi, in spite of all the craziness around....

Thanks for heads up on that one, Jeff.
While it isn't too far from my other part time location in Corinth, it does give me some design ideas.
Regards
John

Here is the diagram of the shape I want to cut. Although the size is a variable, the principle of the machine as I see it should be as simple as possible.
CNC mount cutters exist, and run to about...

As if I hadn't enough on my plate, I'm considering the possibilities of this as a next project.

A picture mount cutter ( I think you call them mats over your side of the pond) that will only be...

Only four weeks to go.
Don't we have any zone members in Northern MS or Southern TN ?

John

I'll certainly give that a try, so thanks for the suggestion.

I'm having no luck in finding a source of stainless steel strip 5 mm wide by 0.4 - 1 mm thick, preferably in UK.
I've had a quote for laser cutting from 0.9mm sheet, but that's far too expensive....

Hi All,
I'm going to be in Corinth, MS during September, and it would be a great opportunity for me to meet up with any zone members willing to meet a genuine UK eccentric !
i shall be reasonably...

Yet another idea to throw into the pot, though I'm not sure if I've mentioned it before.

Start with your cnc machine. Replace the router with a spring loaded probe consisting of a polythene tube...

Of course it would be easier, Russell, but hey, where's your sense of adventure :cheers:

PS nail decorating parlours may be a local source of small quantities of uv gel, but don't tell the...

The more i think about this gel idea, the more worried I am about the surface tension effect. If it's sitting on a clean surface of the copper, what sort of problems will occur re the cross section...

Screen printers, amongst others, use a uv cured resist. It is quite viscous, but might be an alternative route if you were considering the 3d printer approach.
Perhaps there's a uv curable gel that...

Hi Old Buddy,
I was thinking of contacting you on the very same subject earlier this week, but been dashing about, and didn't get round to it.
It's midnight here, and I'm just back from a 200 mile...

Hi all,
Been a while since I visited the forum, but alongside various other projects ongoing, I now have a 13' long stairlift installation which I need to take out from the house, after the passing...

I guess it's my own fault for a poor choice of the word 'synchronously' in my title. Trying to keep my cards too close to my chest !

Basically trying to get the two arms working together, each...

This is very much the way I am going.
I've built a 6 channel controller/driver, with separate 'homing' circuits for the left and right arms, using optical interupters and logic ic's for each motor....
