The difference between BT and ISO is primarily the top/small end of the taper, although I think there may be differences in the large end where BT tooling gets held by the toolchanger.
ISO has a parallel shanked section extending past the small end of the taper, whereas BT simply stops at the end of ...

Only just seen this.

I honestly can't remember how much space there was to fit longer sensors. I just took the easy option of replacing both with identical sensors.

That Mycncuk link is to my Triac retrofit :-)

However I've never measured the spindle run out, and I've still never reconfigured it to run above the servo's 3000RPM rated speed (I replaced the DC motor with servo).
I was only going to push mine to 4500-5000RPM though, to get some improvement with ...

I've just checked my old orders, and this is the sensor I used - https://uk.rs-online.com/web/p/proximit ... rs/4370735
You may want to be sitting down when you look at the price though!

I can remember the sensor came from RS, and there were very few options the same size.

I won't have time to find the details until next week, but the details of my retrofit can be found at https://www.mycncuk.com/threads/10344-Yet-another-Denford-for-the-collection-%28Triac-Retrofit-thread%29 which ...

With the original setup, the limit switches were wired as part of the E-stop circuit, so if any were triggered, the entire machine came to halt.
There are arguments both ways as to whether that is appropriate or not, but for a primarily educational machine, it's probably the correct choice.

The ...

Spare reservoirs are available.

IIRC the C number refers to the exact configuration of motor. It specifies the motor speed/plunger cycle time and the voltage.
They're not a complicated thing, and the final motor drive is likely to rotate very slowly, so may appear to be seized if you try watching ...

What's wrong with the one you have?
They are quite a simple setup, and most spares are available for them.
(lubetec.co.uk are the dealer who I've used in the past)

If it's because oil is making it to the ways, it's far more likely to be an issue with the metering units (they can block, and the only ...

On my Triac the toolholders often wouldn't release when the pneumatic cylinder was activated, and after checking the oil level in the cylinder, which was OK, all it needed was a little adjustment to move it down nearer the drawbar.
I've not had any problems since.

What is de reason you went with Mach and not Edingcnc?


Why go with Edingcnc and not Mach4/Centroid/UCCNC/<other machine controller>?



No idea yet, just trying to figure out why mostly see Mach users and less Edingcnc


Simply because Mach is one of oldest and most popular machine ...

L is an older imperial pulley/belt tooth size.
150 refers to the belt length. IIRC the older imperial sizing is in length, so 150 meaning the belt is 15" long. (metric belts are typically measured by number of teeth).

The only thing you need to physically measure is the belt/pulley width, but going ...

They are item 032 in the Barafuldi TOE80 manual (page 18 shows the diagram).

They fit under caps on the front and back (as you face the lathe), which IIRC require a pin spanner to remove.

It's been a while since I sold my lathe, but I think they're either a hard rubber, or some form of plastic ...

It's probably just needing new buffer pads.

IIRC James knows the dimensions and has made them in the past.

Do you have an oscilloscope, or multimeter with a frequency (Hz) display?
First check is obviously the basics, in checking there is power/gnd going to the encoder.
You can also try measuring the encoder output voltage, and moving/stopping the spindle in random locations to see if the output changes ...

I looked for a replacement after I crashed my turret shearing a few pins and splitting a couple gears, but I couldn't find anything suitable.
I never found any small enough horizontal turret, even trying various Chinese manufacturers.

In the end I got new pins and gears custom made, however I did ...

Does anybody know the specification of the gas strut that holds the enclosure open?

The necessary details on the label on mine have faded.

Sounds like you're going to have to dismantle the turret.

I crashed my Cyclone last year, which resulted in shearing the three pins that carry the epicyclic gears, along with splitting one of the gears.
I did get in touch with Barfuldi, but the only thing they offered was if I sent the turret to ...

They're connected to the stall detection output from the Sprint drive.

The main reason I bought my Triac, was because it included a collection of tool holders.

I have bought some random holders via eBay, but BT35 stuff is getting pretty rare. I can't even remember the last time my saved search suggested any in the UK.

I ended up getting a custom batch of ER holders ...
