General Mach Discussion / Sanyo Denki BL Super servos

« on: January 26, 2007, 10:01:51 AM »

Hi

I just got myself 4 Sanyo Denki BL Super servos for free, inkl drives.

I just briefly looked trough the manuals , and it looks like they can be used for positioning control by negative command pulses and positive, they also have encoders for feedback.

Does anyone know if this equipment is possible to run under Mach 3?

I am planning to substitude my steppers for these servos.

They used to be controlled by an Omron PLC.

here is the g-codes as i run them, and it would be nice if someone could take their time to run them on their mill, simulation or in live

G-Code, CAD, and CAM discussions / tool offset problems

« on: September 06, 2006, 11:57:21 AM »

Hi
This problem might have been asked severel times before, but i could not fin any threads answering my question.

I am a total newbie to cnc and G-codes.

When i For example try to cut a circle drawn in Autocad and stored as dxf, and the import it to Mach3 it cuts, no problem, but the problem appears when i want to set the tool offset.
I hav tried to manually put in G41 at the top of the code list and it cuts outher an G42 for inner (correct me if I am wrong)

The problem is that the tool stats atthe startpostion in the lower Z pos and then moves out to the offsetdiameter of the circle
i dont know if you guys understand what i mean, but in short the piece that i want in the middle (circle) gets a mark of half the tool with

Sorry, ill try to post a picture of it if you guys dont understand my messy explenation.

Can somebody tell me how and where to write th G41 and G42 codes in the g-code table?
