Hi All

My first post in the Shop Sabre section of CNC zone.

I used a friend of mines Shop Sabre 7214 router today, went armed with NC code produced in BobCAD V28 using the Shopsabre post supplied by BobCAD.

As soon as the control got to the line no 6 with T1 it stopped and said missing file. I got over the problem by manually editing T1 out and then doing a seperate NC file for where tool 2 was called up.

I dont like not understanding this. I had hoped to do a manual tool change and set T2 onto top of stock as per T1.

So I downloaded a post file from WinCNC to use with BobCAD and that turned out the following code which never called up a tool as far as I can see, does not even look like it has started the spindle!!

[ PROGRAM NUMBER: 100 ]
[ PROGRAM NAME: VAC BED TOP WINCNC.NC ]
[ POST: WINCNC ]
[ DATE: TUE. 07/19/2016 ]
[ TIME: 02:23PM ]
[12.2mm MDF]
[Grid will cut 3.5mm deep]
[Circular hole will not break free to save damaging cutter]
[Outer will be done in two passes with a tab at either end]
[ T1ENDMILL ROUGH , DIAMETER = 3. , LENGTH = 45. ]
[ T2ENDMILL ROUGH , DIAMETER = 6. , LENGTH = 60. ]
N01 G90
N02 G53
N03 G54
[Machine Setup - 1 Profile Rough]
[GRID 1]
N04 G00 X63.75 Y335.
N05 Z5.
N06 Z2.5
N07 G01 Z-3.5 F500.
N08 Y55. F2000.

So my question is how do you do a manual tool change with the WinCNC control ie what code do you use, for the life of me I have not been able to find the info.

Once I know what is required in terms of code then I will edit the BobCAD post to get the correct code.

Many Thanks

Barrie
