Looking at that, that's an example for something with an incremental toolholder (something similar to your Triac, but you only get a single pulse per tool position), however what it does show, is...

Chaz been doing little digging and looks like the acorn is setup in such away that it watches inputs to determine where the turret is located.
This is why the Orac code is so simple. The PLC is...

It's not listed on the features, but this tells you what you need to know about threading and encoders - http://forum.cncdrive.com/viewtopic.php?f=19&t=299

order a braking resistor too 50 ohm 300 watt ( ecogoo stock them around £30)

Did a little more work, haven't finished these side plates yet but thought I'd show where I'm up to.... they still need milling on the underside but I haven't quite decided how I'm going to do that...

Actually that's just the angle of the pics, I designed it with the idea of having the bottom of the spindle nut approximately 1cm below the bottom of the mounting plate for that very reason....

I'm using my trusty old makergear m2... I've had it for about 5 years now and it's still churning out lovely prints. I actually designed myself a new super duper printer which I'll make one day once...

Cheers desert.



Yeah very annoying, but could have been worse I suppose...



They came with some plastic tubes actually, but thanks. Of course I tried to use the Z-axis 1604 ball screw's...

Back to the build!

So had a chance to make my rail alignment doohickeys:

looks like Thor's done a lovely job on those plates!

I've been thinking about exactly this problem for my own machine (also using CSMIO). I haven't built the touch probe yet but I was intending to use a simple bit of circuitry to invert one of the...

you could use a relay on one output to get both of them to NO or NC

Having now seen Thor in real life I can tell you the pictures do not do it justice and then she moves and when she moves the earth moves with her lol.

A true work of art

You could​ probably get a lot more torque on low rpm by using proper vector vfd. I dont know if chinese make any, oh and I have seen limit for vector use of vfd on max 200hz, so its worth checking...

A few months back I drew up a TTS/R8 style spindle to make sure the machine I am building would allow me to upgrade should I decide to go that way. Here is an overview of the basic parts:

Couple of jobs done today, nothing overly exciting sadly!

I made my drill jigs after a few changes to my design to allow me to use it in multiple places.

So, first things first - big delivery of eco-cast plate! Enough to keep me going for a couple of months I'm sure.

Managed to have the big bugger (the bed tool plate) fall over on my foot as I was...

Yep, never get any grinding dust near a machine with slides, ways or screws, unless its a machine built for grinding - instant death of many a lathe.

Chaz - that looks suspiciously like a ready-built grinding spindle for the Quorn tool and cutter grinder. This was a design from 1974, sold as a kit of castings and hard-to-get materials. Quite a lot...

So been a bit busy with work, but this afternoon I had a bit of a play with the lathe.

Trying to make some nice snug shoulder screws for the alignment of the X-Axis mounting plate. I've just been...

Check his channel on you tube. There are 10 or so videos where he explains everything in detail https://www.youtube.com/user/Simpsons36/videos

Simple bypass from output to input - just a tap that can be opened gradually and you can set the pressure exactly as you want it. This was standard practice on the main Grundfos 3 kW pumps that...

A few have used these and they prove more than up to the job: http://www.ebay.co.uk/itm/371128026468, you dont need to go mad trying to cool these spindles down, they are quite efficient and...

Noice!

You must be chuffed - looks like it'll be a monster.

Congratulations! Its so rewarding to see the result ++++++++++++
