Are you sure you want EN8? Sheet spring steel tends to be a different material. Something like this perhaps?...

Check out the "Nano coated" cutters from APT - I found they work very well on steel if you have a spindle that doesn't give much poke at low speeds.

Well done Wal, that looks fantastic. Excellent finish.

You need to get out more....Oh, sorry!!

Nice piece of work, and it ain't going to break again.

Merry Christmas All !

Thank you to everyone for making the community what it is, its continued success is in itself my biggest reward and I look forward to seeing what next year brings.

I have the Amadeal 290-VFF, so out of interest I had a look at the other offerings from Amadeal and they seem to have retracted their catalogue somewhat. There are others that sell the same chinese...

Bake your rods at 200 for 1 hour in the oven and then test one, they'll usually be fine.

Yes that is one way. But is far simpler to just edit the ini file as you can get very fine adjustments. . (This is for the benefit of others to see that the config files are just plain text)

Is it 'auto-squaring', 'auto-racking' or 'auto-un-racking'? Anyway the 'master' version 2.8 of LinuxCNC has a lot of differences under the bonnet compared to the current stable 2.7. The reason I...

Well, what a year it's been and how fast it's gone!

Merry Christmas everyone and a positive new year to you all.

All the best,

Lovely job Wal!
Though we expect nothing less of you ;-)

I don't know about it's output, the machine itself is a work of art!

Wow,it really detail all processing,wonderful.

Very nice Wal :thumsup:

First and second pics show bearing blocks on smaller press with lift springs. Third shows to and bottom roller - actually on this press the bottom roller is slightly ribbed with circumferential...

Going by that photo, the springs only serve to raise the roller up when tension is removed.

If you design so just the screws lift the roller, you're likely to get a bit free movement while going...

Thanks! I sandblasted the aluminum, painted it using 2 component base for epoxy and polyurethane, then coated 2 times with polyurethane. Then sanded various papers till 2000 grit. I think the base...

If the correct speed is maintained during G2/3s, and not using G1s, then the problem is likely to do with lookahead/smoothing settings, or even lack of processing power.

Lookahead would could...

The 2A rating on the switch is the breaking capacity of the switch. That is that it will reliably switch off a current of 2A without the inevitable arcing across the switch contacts welding the...

You are over thinking it.

While you are technically correct, even a 2A rated switch will more than likely survive switching a load that will blow a 3A fuse.
You've got to consider what kind of...

Wal See your email. It is the contacts that are rated at 24v 3A

I would expect the NE555 can not provide enough current to operate the
solenoid valve without the addition of a high gain power transistor
like the TIP122
the 1N4001 across the coil is the...

Wal I have a 12V solenoid air valve if you want it give me a shout. I think you might need a fly back diode across it.

7 days until we leave for the TT...

I like to use this calculator to calculate the Tangential cutting force, that is how hard the machine is pushing the bit sideways through the material. In my experience you can bet any...
