Denford Mirac conversion help

[m_c]

I've just had a look at the Mirac lathe specs and realised potentially what turret it comes with.
If it is a Barafuldi TOE80, then you will not be able to control the turret directly via a Mach 3 macro, Mach 4 might just about manage the timing, but I wouldn't be 100% sure about that, as the timing requirements for the turret require fast responses to inputs/outputs.
Something like a KFlop could, as you can programme the KFlop directly to handle the toolchange, and Mach3 would simply command the KFlop to carry out the tool change.
.
The other option is to use a PLC to handle the tool change (I used a Click PLC, and you're welcome to the code if you choose that option).
.
One thing I should mention, is that even although KMotionCNC does everything I need it to in terms of running my lathe, I do miss the wizards in Mach 3. However, if you have a Mach3 license, most of the code will work, it's just canned cycles where things generally won't.
.
Personally, given the Mirac will most likely use 12 or 24V control circuitry already, I'd be looking at something from CS-Labs, or a KFlop+Konnect(IO board)(+Kanalog if you want to run analogue servos with the KFlop closing the loop).
Smoothstepper/Pokeys only work on 5V.
I can't comment on PlanetCNC, but there are suitable MESA boards available for LinuxCNC, but as John says, help can be very hit or miss.
