Welcome to the SeeMeCNC Community

I've looked throughout the manual and cannot find anything on the LEDs--the green and the yellow.

(My) green is on, and yellow is blinking. Is this normal?

My 'puter still cannot communicate with printer. Com3 is getting ACCESS DENIED window. I cannot figure out how to get it all working. Instructions has no advice on the matter.

ANY info would be GREATLY appreciated.

Thanx in advance.

Did you install the Rambo driver?
If so, does windows recognizes your printer? Check under Pc Settings / devices

I finally rolled back the 'puter to a much earlier date--soon after I had gotten everything up and running (a year ago). Of course, the printer is now communicating with 'puter.
I investigated the driver and (see pic) this is the details. I believe the previous (before rolling 'puter back) was NOT this. I do not remember what it was, but I do not recall this.
Unfortunately< i must put the 'puter back to the up-to-date settings as I have lost a bunch of files. Freakin' WindBlows. UGH!!
