Siemens 840D Troubles

[Thee Awbade™]

So, new to the Siemens world, 

 

I'm having an issue with tool-changes during an automated program. I can change tools just fine in Jog. Just a simple 

 

T1 

M6

 

Command does it fine. 

 

However; the code in the automated program outputs as 

 

G0 SUPA A0 C0.

TRAFOOF

G0 SUPA D0 Z0.

ROT

TRANS

G0 SUPA X0. Y0.

M5

M1

;T3     - 3/8" CARBIDE ENDMILL - D1     - DIA .375"

T3 D1

M6

T2

 

This pops an error saying "Waiting for Master Spindle Speed SP1" And it waits and it waits and does nothing.....

 

Any ideas?

I generate a tool change on a DMG DMU50 like this:

 

G00 Z0.25

M09

M05

CYCLE832(0,0,1)

 CYCLE800

G00 SUPA Z-0.1 D0

M01

 

;0.3937 BULL-NOSED ENDMILL 

; POCKET

G00 G17 G40 G90

T225

M6

G509 D1

CYCLE832(0.002,2,1)

G00 G90 B0. C=DC(0.)

G00 G90 G17 X-0.0418 Y0.1655 S10000 M03

M08

 

Maybe try not turning the offset on on the tool call. Try moving the D1 to after the tool change. It shouldn't make a difference, but you never know how the MTB set it up.

Alright I'll test that on Tuesday when I get in.

 

The machine does Tool-Changes just fine in Jog and MDA Mode, but it's just the syntax of the code in Automatic Mode that I'm having a little trouble dialing in.

James,

 

You can not pre-load tools on your machine.

The machine has a static tool changer with defined positions.

It's not a random carousel like on many machining centers.

You need to have the post modified to not output the next tool after the M6.

 

Also, make sure that you have defined the Max Spindle Speed for each tool in the tool data.

 

I got back late on Friday evening from Italy.

Shoot me an email with your current status and I'll do what I can.

Thanks Tim, I thought that the preloading was odd myself, but I tried modifying the code on the controller and that alone didn't solve the issue. We're having other issues as well that will need a tech to come out for so when the machine is working again on its own I'll test out a few more things and email you
