Thread: Moving up to a bigger machine...
I have been using my mini-mill with the excellent 2010 screen-set for a while now, done some nice jobs too. I also have a Bridgeport which is going to be CNC converted as a project soon.
Trying to figure options for Z zero setting - on the mini-mill the semi-auto-manual tool change macros work wonders but I cannot use that on the bigger machine due to the flexible nature of a Bridgeport, there is nowhere to fix the fixed height sense plate.
Am I right my only option here is to use the floating probe plate for every tool change?
The tools are held in R8 collets so pre-set tool offsets are out, just as the mini-mill is.
Is it not possible to just use one corner of the bed for touch off second plate an isultated plate that bolted on end of a T slot on one corner would do same job as one used on mini mill
Ah, but you have not used a Bridgeport ;)
The head is mounted on a swivelling, ram that can (and does) move in any position - the chances of the macro finding the fixed plate are practically zero after the head has been moved ;)
Offsets ;-)If you will not be swayed by logic or experience simply pick the idea you
like best, but ask yourself why you sought advice in the first place and,
for a simple life, perhaps consider not doing so in future
Yes but how?
There is no toolholder as such - just a collet.
The Knee height (i'll call it Z2) is adjustable 300mm.
Only the quill- Z1 Is homed and controlled.
Seems too many variables for a simple offset, unless I am not seeing the whole picture yet;)
