Haas DNC settings

[Shawn Wentzel- Wenteq Inc]

I am having a problem setting up my Haas VF-4 for communications. It is a 1998 model. I am using cimco editor that comes with mastercam. If anyone could please send me a screenshot of the settings used in cimco it would save me a lot of guess work. also if you could provide the settings for the machine. I don't know if I should use Xon/Xoff, DC modem, ect.

7,even,1 and you need to know the baud rate from the control.

Do not need Xon/Xoff, DC modem, ect.

 

this should work.

my control stettings.

 

baud-115200

parity-even

stop bit-2

synchronization- xon/xoff

data bits -7

 

Make sure your got a proper cable, too.

Hello,

 

The HAAS machine defaults to xon-xoff syncronization. While the machine will do software flow control using this setting, it is better to set the syncronization to DC CODES. The HAAS will then perform X-ON handshaking when the Recv RS232 button is pressed. Set your DNC software to Wait for X-on or X-On Hold or however they word it in Cimco and send the file. At the machine - receive and the display should go from Loading... to the O # in the program and then SND Done.. The file will now be resident in the memory of the HAAS. Make sure the first and last characters in the program are a % - otherwise you may end up with a RS232 buffer empty alarm or be stuck in a Loading... mode until reset is pressed.

 

Good luck,

Thx John, I updated my settings and am enjoying simpler file transfers...nice now to just post a program and have it "wait" for the machine to accept it.

Glad I could help. There are several quarks to machine tools that make life simpler when they are resolved. That is one of the key components to choosing a DNC vendor - it's not just the software or hardware but how you 'tweak' the controls into the system. Same reward is found with a post that is tweaked to a control - so you never have to modify the NC code (in an ideal world)! Now if the post was 'perfect' - we could just bar code the raw material and have the Cam system post the file on the fly while it is drip-feeding the machine...
