I'm relatively new to MachScreen. So, here's my question: I placed a "Tool#" DRO & a "Tool Dia" DRO on my screen and followed up with the "Function Code" for  both. Now, does the "function" read the G-ode and list the tool number & diameter in the DROs, or does something else happen? DRO remains 0.0000. I ran a program listing T1 as the tool (with tool # & Dia.) and the Tool# & Tool Dia DRO's remains 0.000. If I try to enter a number in the Tool# DRO, it returns to 0.0000. The DRO for TOOL DIA excepts the number entered. This is making me CRAZY!!   

I believe the tool # DRO displays the current tool #, which is also displayed in the corner of the toolpath display. To change it, you need to do an M6 Tx.

Gerry,
Thanks for the quick response! The tool number shows up in the top corner of the tool path, but all I get in the Tool# DRO are zeros. I have the /M6 T# coding in the program, it just does not read it into the DRO.

I don't use machscreen, but it sounds like you have the wrong DRO function.

I have tried both (only) Tool #DRO's listed. Neither seems to work.

1:  Current tool number DRO, Standard Code= 24, Format= %4.4f
2:  Tool number DRO, OEM Code= 824, Format= %4.4f

Open to suggestions!

don't know if you solved your problem but....
make sure you're editing the correct profile. i did
that. work a whole day then found was working on
wrong profile. also,if you have mach3 open, you
have to reload the saved set file.
Good Luck

Got it to work late yesterday! Still not sure how!! I really like this program though!

Thanks!
Bob
