Mach4 General Discussion / Re: Turn | Is eccentric turning possible with Mach4?

Check with Les over at Sheetcam. Years back he helped me with applications to CAM out Crankshaft grinding and Camshaft grinding using Sheetcam to create teh Gcode. Both functions are about what you want to do with OD offset grinding. I have teh plugins here somewhere but Less might remember doing it as well.

I beleive you will find that teh ESS is causing that problem not Mach3 (;-)

What controller are you using ??

iF you assign teh same pin/port numbers for spindle and axis control what exactly does Mach3 do today. Many years back We used that same process to run a S/D spindle as Spindle and Caxis without a problem. BUT that was with a LPT port version of mach3.

What controller are you running ??

You say Mach3 complains about that. HOW does it complain ? will it still run teh Axis both ways ??

When you get the encoder set up TRY teh Mach3 G32/G76 routines to see if they work. The testing I did with this was 3 years ago.

You might start with emailing Stoney and asking them that question.

Just a thought, (;-) TP

I would keep teh Pulse count low as in 100-400 PPR and yes teh ABZ is what you want.  as to wiring it up I have no idea how your machine is wired. Only you will know that.

Hi Rich, NO in mach3 threading is G32. Only when using UCCNC does it use G33. Yes teh G76 is different BUT I do have a copy of a G76 macro I wrote that will work in Mach3 using teh UC400eth.

As to teh encoder it can be done many ways as long as teh results is quadrature AB with a single index per turn of teh spindle.

The parameters and Gcode call is exactly the same as LinuxCNC uses. I have a doc for that as well if needed

There is also a Macro to do rigid tapping in Mach3.

CNCDrive does not tlak about the plugin for Mach3 as they officially do not support TURN with UCCNC products. EVEN though they did create teh thread function for it.

You do have a UC400eth correct ? That is a UCCNC control board. The breakout board is not a concern unless teh Opto couplers are too slow to see the encoder signals properly.

Yes I know it gets complicated some times.

The UCCNC boards require a 3 channel encoder( ABI ) for threading. The encoder HAS to be running at 1:1 with the spindle.  With this setup you can do guage perfect threads every time.
