New from Old / Re: The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)

The really frustrating part is that this same RS232 link is used for uploading and downloading programs to the controller and works fine.

STEP5 was originally written I believe for CP/M where you had far better direct access to hardware than Windows lets you have.

This of course is a distraction from a detour from a diversion on the way to trying to solve the 'Spindle Orientation' issue, and although I'd love to be able to poke around in and maybe re-program the PLC it wasn't an objective that I chose!

I'm getting closer to being driven to load the PLC program from the other (smaller lathe) and see if the spindle orientation works with that. But it would have to be done with the greatest care in case the axis etc are over driven.

Hopefully then the controller is not as stubborn in the parameter department as step 5...

Great stuff George! Could you show us the circuit diagram please?

Russ,

I've set the COM2: to what I believe I need using MODE, run STEP5 then (exiting STEP5 first as otherwise it still has hold of the COM port) then typing just MODE COM2: to see what it's set to find that STEP5 has modified it yet again

Yesterday I thought, OK, that's what STEP5 seems to want, so (contrary to the instructions) set the Siemens 820T controller to those settings and see what happens. It will still go on line but locks up as before.

All very intriguing, rather headache provoking, but never the less interesting. I wish I could have a few hours solidly 'at it' but things keep getting in the way !

I just hope that PK is having more success and less headaches down under - not heard from him in a while.

Did you also use mode to set what you need? Clearly some very odd interactions between all the bit players in this drama.

If only they would exit stage left and leave the main characters to read the script...

I would think, as a last resort, you could set an arduino or similar to act as a protocol converter.

Last thought

Can you reinstall using the new ini file? It may just use it to set some run config when it is first installed /configured

Oh, my first initial in script: R.

D'oh! I forgot the attachments are on top! Yeah, you want the top level!

The bottom plate is for the z zero prox. I'll take a pic tonight.

Mine has been cranking on a print for two days straight, after the first 36 hour print finished... full scale, here I come!
