I´ve just finished retrofitting a Boxford 280 Turnmaster lathe with USBCNC CPU5B professional from Bert Eding (Eding CNC - PC based CNC control). I´ve bought Partmaster Lathe cam from Dolphin.
Do anyone here know what Postprocessor to use?

Peter,
Other than suggesting the Mach driver I can't help but I'd be interested to know how it works out as regards threading.
Mach, using the parallel port is useless. many who say they don't have a problem do have but they don't do long enough threads for it to be apparent.

HI
I´m beginning to modify the Mach postprocessor, but I´m a newbie to lathe postprocessor, so I´m afraid of making mistakes. I´m done with the groups. Can you se if I´m doing right so far? I´ll try to attach a copy.
I have tried to make a simple job of turning an arc, but when I load it into USBCNC it tells me: Radius of end of arc differs from radius to start.

Regarding treadcutting I have not tryed it yet, but I have a sensor on my spindel, and I understand that it syncronise the startpoint of treadmaking (G76 in USBCNC).
Is it very expensive to get a customised postprocessor?
Regards Peter

I think the problem with the arcs is a question of the centre coordinates being either incremental or absolute.

Can you change the setting in USBCNC ? if not the post can changed.

The standard Fanuc post - T_F0TC, uses incremental - have a look to see the difference between under the macro section, here is the entry

#I = { (($YCEN-$OLDY)/2):XARC }

Absolute would be

#I = { $XCEN:XARC }

Hope this helps.

hi Peter Nielsen,

I am also using USB CPU V5 by eding cnc for my CNC Plasma/oxy fuel Combo with spendel on it, i also use sheetcam for converting my cad drawing to g-code and i am using the EMC plasma processor.

Also if you use this on cnc lathe try the EMC, but i am not sure if it work.
Please send me a feed back what happen because i am also planning to build one of cnc lathe using USB CPU.

Thanks:cheers:

Hey there,

any news here? Or still no PP für USBCNC-Turning available?

Regards,

Need a postprocessor from EdingCNC USBCNC to Dolphin Partmaster Lathe.
Do anyone know how to create it or modify and exsisting postprocessor??

I'd be very interested in a postprocessor for EdingCNC, too.

It's somehow disappointing, that even after such a long time and worldwide grown distribution of EdingCNC, there still isn't any matching postprocessor available from Dolphin itself...

[G59]

It's my understanding that EdingCNC works well with standard Fanuc GCode. So Fanuc 0T or 6T, should be OK provided that Dolphin has a post processor that can spit out the standard Fanuc GCode.

No, it doesn't. I tried every PP of PML, but there is no working one.

[G59]

EdingCnc interprets standard G-Code ie: RS274/NGC which Fanuc-0T uses.

DolphinCam surely has a post for this old control?
I don't use Dolphin or Mach, so can't really help.

Good luck.

[Peter Nielsen]

I have also tried almost every postprocessor from Dolphin, but still havent found anyone that works. Now I´m trying to find out how to use the posteditor, but I´m not very good in programming.
If I find a solution on the problem, i will post it here.

Dolphin / Partmaster I'm sure they can help you with your post processor, it needs to output the I's & J's as Incremental, this is industry standard, I'm using Gibbs Cam with Eding control for mill, it is almost perfect with a standard Fanuc type post, most other post processor's also follow the Fanuc style of programing, usually with just a tweak here & there you will have good clean code to run

[mactec54]

Peter Nielsen

I ran your program, there is something wrong with your programing, the first ( 2 ) I & JKs work just fine, Line 200 & Line 220 so I think you have a problem with your Drawing or how you are programing your part, your post processor is outputting correctly or line 200 & 220 would not be working as well

I changed your program some at the top & bottom, removed the I & k lines that were not correct, these need to be correct for the control to run

Peter Nielsen

This may help you with your programing,

[gerry1960]

Peter do you still have the Fanuc orginal parameters and diagnostics for the boxford I am in desperate need of some.
