Denford Triac Spindle control / ATC

[andy_con]

spindle encoder? do you mean rpm feedback into mach?

the spindle doesn't affect the atc in any way. the z needs to be at the correct height so the atc disk can collect the tool, that's it.

I don't use any temp sensors

Hi Andy,

Thanks for the advice so far. I'm poor in money and time so I'm going to have to break this down into smaller chunks. So I'll concentrate on the spindle drive and control and get a V5 card. Can you tell me what you used for the spindle encoder, did you buy this or make it? Any pictures you could send me please?

I do have a few more questions regarding the spindle, I've watched a few videos on YouTube of the ATC mechanism working. it looks like the spindle is positioned and locked in place, is there a mechanism within the motor spindle assembly that clicks in to do this? Or is aligned with the slot on the encoder and then motor braking is applied?

Do I need to have any more inputs to the Sprint card such as breaking and the Taco? Lastly I have a temperature sensor wired in the spindle motor, does this do anything, do I need to use it?

Cheers

Mike

Ive done a Denford Triac mod to a CS Labs unit. I can help answer a few questions.

1. The spindle drive needs to be isolated. A new sprint 1220i drive is around £250.
2. The ATC needs that Z is set roughly at Z + 30 from home. This is set for me via my macro for M6 in Mach 3.

You do not need a new sprint card, ignore that advice. You just need to use a v4 or v5 board, they work perfectly

Gents,

Been away for a while, just catching up now. Thanks for all the input been very useful, especially Andy. Think I have enough to be getting on with now, sure I will have more questions down the line.
