Then as far as your encoder is concerened I can no longer help, I have told you all I know to tell you, perhaps someone else can chime in who has more recent experience.

For DROs, just drop on on the page, and put in the OEM number the UserDRO number or OEMnumber you want.

SCOTT i'll give this a whirl(;-)

OK for now go BACK to the original screen for mach. Set up the encoder for 4 pulses per unit, SAVE the settings . MAKE SURE you are setting the correct pins and ports to the correct encoder input in this case i would use encoder1 which relates to X axis DRO on the settings page.

NOW rotate the encoder 90 degs. WHat does the dro on the settings page report as number of units???

TP,

I am using Encoder 1 X Axis DRO. I changed it to 4 and saved the units. After rotating the encoder 90 degrees, the settings page reports 360 degrees. This value is found under Abs Coords, MPG1, Count. Should I do anything with the velocity value? I have tried changing it, but it doesn't seem to do anything.

I have no idea what you are trying to tell me. This has nothing to do with any of that.

YOu should be looking at the ENCODER POSITION X axis dro ONLY. WHat does it display for a value???

The encoder position X Axis DRO reads -2.5500. If I rotate the encoder, the DRO does nothing. The only thing that updates is the MPG1 Count DRO above the Encoder Position X Axis DRO.

(;-) YOU don't have the encoder setup correctly. IT appears you are trying to setup an MPG.

SET up the encoder AS" encoder1" NOT mpg#1. Use 4 as counts per unit.

Then see IF you get a reading on the X pos dro on the settings page.

Why have you set up the encoder as a MPG? Are you not wanting it as a way of seeing the movement of an axis?

AH! I feel like an idiot. I can't believe that has been the problem this entire time. For some reason I (1) never saw Encoder 1 under Pins and Ports. I always thought that Mach 3 wasn't able to handle Encoders, and the encoders had to be read as MPGs. Nevermind, thanks for the help.

How do I assign a User DRO number to a DRO in screen designer? The only option I see is OEM number.
