Re: New triac PC project

I'll be getting back to this soon. I got side tracked converting an Emco PC turn 55. I have control of everything on this with a cheap breakout board. But while converting the Emco I used a control board called a digital dreams EC500 V5 board. They can be bought for 80 euro from AliExpress. These ca...

Re: Triac PC spindle taper

Just got a quote for the power draw bar conversation. Eye watering is an understatement, 627 pounds :(

Re: Triac PC spindle taper

That's great info thank you. I'll be looking at converting it to a pneumatic draw bar at some stage. It's the gripper collet that grips the pull stud up I think will be the difficulty if denford don't still sell it.

Re: Triac PC spindle taper

When denford released the triac versions, the ATC and the manual version. It says in the manual the ATC came with the BT30 and the manual iso30. Has the bt30 spindle the dog legs to stop the tool rotating? Or is the spindle the exact same between the bt30 and iso30 versions?

Triac PC spindle taper

Hi, I'm trying to figure out what taper is inside my Triac. It's made in 1998. It is the Non ATC model. It came with the easy change tool holder. I think they came with either an R8 or BT30 taper for the manual change models ? Pics of the tools that came with it. It looks like BT30 ? If it's BT30 it...

Sprint 1200 blown

Ok so it's looks like Iv blown my sprint 1200 controller. If I hook up an isolated 5v to the input it's making noise but the motor doesn't turn .if I hook up 10v it turns but not very fast. It's is only supplying the motor 16v. Anyone know what part of the board controls the regulation? If I can try...

Re: New triac PC project

Yes, they are feed by a 12v supply. Iv left the Denford control board installed and just tapped into the numar sensor wiring. You could take out the board and feed them with 12v and experiment with different ohm resistors(1k up). They sit at about 8.2v when there is no metal and about 11.8-12v when ...

Re: New triac PC project

Yep not isolated, I used this little board to isolate it https://amzn.eu/d/doKiPh3 I have nearly everything working now just needs tuning. Axis, spindle, oil pump, coolant pump, limits and homing sensors. All denford original boards using a cheap Chinese Bob. I have an emco pc turn 55 to retrofit af...

Re: Help with Triac VMC converting to Mach

Hi Dan thanks for this write up. So for the voltage Amp circuit. The step and dir wires from the driver board are 12v. They connect to the collector of the transistor. 5v from the BOB connects to a 2k resistor and then to the base. The Emitter is connected to ground(same ground as BOB and Driver boa...
