General Mach Discussion / Re: Mach 3 toolchange for dummies???

Hi Hood,

Please find attached Macro and image of screenset I am using.

I think I need to set the DRO at the exact angle after every toolchange, this macro sets the dro to the requested angle to pass the rachet. ie 47 degrees for tool 2 which means that it tool 3 is set to move to 97 degrees it is only actualy moving 45 degrees and does not pass the ratchet.

Can I use the tool table to enter the angle of the turret and read this from the tool direction reading on the screen.

Regards

Hi Hood

You enter degrees in tool position in the tool table.

Hi Hood,

I have a label with tool position showing the degrees of the tool position which has an OEM code 106 Can I use this with SetOemDRO(803,xx) where xx is the number stated as the tool position?(OEM106)

Hi Hood,

SetOemDRO(803,XX)
I dont know where XX is going to be generated I will need to have some way of the program knowing that when tool 2 is selected that the DRO is set to 45 after the change etc.

Hi Hood,

Yes you have to stall it to keep it hard against the ratchet or there is movement in the turret.

Hi Hood,

I was trying to put it to the left of  the X & Z DRO's and zero buttons on the standard screen. Thie other screen I downloaded with the A DRO and zero button from the forum seems to be working well and it does have a diagnostic page.

The problem I have now is that when I move from tool 1 to tool 2, G00 A46 followed by G00 A-40 to return against the ratchet (DRO shows 40 degrees) Then Move to Tool 2 by G00 A91 it moves the tool 51 degrees which requires a larger negative move to return against the ratchet. I know I could just say G00 A85 to get to tool 2 bbut I think that is going to get messy.
Is there a way that I could set the A DRO to the proper value for the tool after the move in the macro? ie After the G00 A-40 set the A DRO to 45.

Hi Hood

I have downloaded another (3 page lathe screen from works in progress) screen set with an A axis dro and zero button and it seems to be working okay without a home switch.
There is no diagnostics screen but I could load the standard screen set if needed.

Hi Hood,

I cant get machscreen to run and I have tried to add a button using screen4 to the standard turn screen to zero the toolchanger but it screws up the position of other elements of the screen.
I am using XP.

Any ideas whats going on?

Thanks Hood,

I now have it operating in degrees and it is working well and I can now  change to any tool using manual inputs. I just need to set up a home switch now so tool 1 is always tool 1.
The next problem I see is that I cant edit the button script for home all on mach 3 lathe to include the toolchanger.
Do you know how I can get round this?

Regards

Arthur
