Re: More Acorn Questions...

M-Codes 0-99 are fully customizable. Using M94/95 in a mfunc?.mac file, where ? is the number of the M-Code you want to modify, you can turn on or off any outputs. Yes, that much I understand. But is it practical to change axis parameters on-the-fly as I've suggested? Is there any way to customize ...

Re: More Acorn Questions...

I suspect I mis-remembered there being some custom macros that could be called automatically before/after canned cycles. I thought I remembered reading that somewhere, but can't' find it again. So, my proposed approach is now: 1) Add external hardware to monitor the VFD output signals (analog out an...

Re: Latching circuit? Is it necessary

From a safety stand-point, a "magnetic switch" is the best, as it is impossible for it to turn itself back on. Softwaare can misbehave, normal switches can fail in an open or closed state. A good magnetic switch, once turned off, simply cannot turn itself back on. And, they are not expensi...

Re: More Acorn Questions...

The spindle drive is a Maxsine TL08F. The specific model installed on the machines in question do not support use of an analog control input. So, switching the drive between a "VFD Emulator" and one of the Step/Dir axis outputs seems to me the only option. http://www.cnckaran.com/download/...

Re: More Acorn Questions...

Clay,

This would have to work on existing machines, and they don't use DMM drives. So, that doesn't sound like an option. unless I'm misundertanding...

Re: More Acorn Questions...

OK, thanks. Next question: One of the machines I want to put the Acorn on has a servo spindle. But, it also has a 4th axis. The servo capability is really only useful for rigid tapping. But, there is obviously a shortage of Step/Dir/En outputs to control 4 axes plus the servo spindle. So, I'm thinki...

Re: Acorn ATC Interface

The ATC is pretty much self-contained, and self-controlled, with its own on-board ARM-based controller. All of the electronics, except the 12V/30A power supply, are mounted inside the carousel housing. It only needs to be told which tool to load, and it does the entire toolchange by itself, includin...

Here is a more recent one - a new system running on the test fixture, with the new 3D printed plastics: https://www.youtube.com/watch?v=7Af9tJcu-to And here is one actually cutting metal - showing off my new home-brew tension/compression tap holders: https://www.youtube.com/watch?v=csLaKGFvvaY Regar...
