I have an SX3 mill that I converted and have been looking to setup the tool offsets for my mill. Finally want to take advantage of the tool change features to speed things up.
I have been able to enter the dimensions into the mill for tool hieght and also have my 1st tool which is the longest. But I have something that I can't seem to get past.
I can setup my mill with a dummy part (cardboard box), then set my Tool 1 to zero with that. (Tool 1 is a 2 Inch plunger indicator set to a specific depth of 6.153" length)
When I cycle the tool change to T2 which is only 2.947", it works like it should and drops to Machine coordinates of 5.980 But when I change from T2 to T4 as a test, the offset stays at the T2 length, even though Mach Tool DROs show the change.
Tool lengths and Zero positions on part top.
T1 - 6.153 (Machine Coordinates -3.0393)
T2 - 2.947 ( - 5.980 )
T4 - 2.154 ( - 5.980 ) (correct tool# and offset show in main screen DRO, but Cutting coordinates remain at T2 offset distance)
I used a macro that I found at Mach3 forums that allows me to go to a position on the table for tool changes, and also asks me to touch off a plate for auto zero, but I do not use that part. Once I click cancel on that, then insert the new tool, it returns to the next cutting coordinates, but doesn't apply the correct amount of offset.
What doesn't make sense though is that if the macro is screwing up the offset entry, why only on the 3rd tool and not the 2nd tool?
I have made sure that the gcode shows
M6 T2 G43 H2 for second tool.
(I've tried with and without G49, no change)
Then M6 T4 G43 H4 for 3rd tool change.
What am I missing?
Thanks for the help.
