Doosan Puma 3100 xly gear changing

[Flycut]

Trying to figure out what conditions need to be met in order to change gears on this machine in memory mode.

I can change gear in manual mode but not in memory or MDI.

I've tried

 

M5 P11

M34

M41 P11 and M43 P11

 

but the control seems to be waiting for certain conditions I can't think of.

 

Anyone know?

Thanks

Here's the correct M-Code sequence.

 

M34 (C-AXIS MODE OFF)

M05 P11 (MAIN SPINDLE SELECT - SPINDLE OFF)

M41 (GEAR CHANGE)

 

Make sure your Machine actually has a geared main spindle drive.

If the above hangs up then you have a standard belt driven main spindle with separate High & Low windings.

 

If that's the case, then for a 30 series control use M261 for Low-winding and M262 for High-winding.

Thank you sir.

M261 did it. Cheers
