Machscreen Screen Designer / DRO setup question

« on: September 28, 2011, 10:42:27 PM »

All,

I'm having a bit of an issue.  If I put a user DRO on a screen it displays zero.  If I put my mouse on it the pointer turns to a hand and I can click on it to highlight it.  I can type in a value and I see the value.  When I hit enter, the value doesn't remain in the field... it returns to zero.

I can hook this thing up to a brain and the value gets passed through, but the DRO doesn't keep the value I assigned.  Is there somethign special I have to do to make this work?  I want it to function like the axis DROs when the machine co-ordinates are turned off.  you can change the DRO value and have it stay that way.  That way I know what it is set at.

General Mach Discussion / How do I make a DRO show an input value?

All,

I am a relatively new Mach3 user and I am beginning to customize it for my needs.  I set up an arduino with an open source modbus IO code to read a flow meter and send a value back to Mach3 to display the flow rate.  I created a user DRO to display the result and I got that working fine.  I also wanted to send back a control to set the speed of the pump.  I created another user DRO and used that value and a brain and send back through the modbus to set a PWM value.  I got the functionality that I wanted, but I can't get the user DRO to display the value I set.  When I click on the DRO, it lightens up some and allows me to set a value (it actually displays the value when I type in it), but when I hit enter, the DRO goes back to zero.  It actually transmits the right information through the brain to the arduino and sets the PWM to the right value, but the DRO always says zero.  I would like to set the value and have it say what it is after hitting enter.  What am I missing here?
