Simplify3D User Forum

Hey guys. I just updated to version 4.0 and it won't connect to my printer. It's an XYZPrinting da vinci 2.0/duo (whatever you want to called it) with the Repetier Firmware .94. In the machine control panel if I click connect I get this.
Now I've gotten it to "partially" work right by opening Repetier Host first, connecting, then disconnecting, then I can connect through the v4.0 software after that. So there is that work around, but I shouldn't have to do that. I'm guessing I need to modify some of the gcode settings or something to get the repetier firmware to acknowledge properly, but I'm not sure what to do here really.

EDIT: And just to clearify, yes, COM9 is confirmed to be the correct port as it works with repetier properly, and after connecting in repetier, simplify works fine. It's just that initial startup after the printer has just been turned on it won't connect. Baud rate was also double checked to be correct.

EDIT AGAIN: Also, it worked perfectly fine in the last version of simplify.

Make sure you're using the right flow control and baud rate

O-o yes.... I did check that all and it still doesn't like it.

So still nothing on this? It's really is annoying.

Is it annoying that other S3D users don' have the same issue?? Or is it annoying that nobody from S3D has responded with a solution?

This is a user forum that has simply been made available by S3D......and they do not respond to pleas for help on here! If you want their advice, you will need to email them at the support email address.

Personally, I don't think your issue has anything to do with differences between pre-v4 and v4 S3D code. The issue started when you installed S3D afresh...so I suspect its something to do with drivers....or the installation has not been 100% right.

O-o the problem is annoying.

So, I downgraded back to 3.1.1 (had the install file still luckily, since I didn't see a way to download older versions from the main download page) and it's all working after I re-setup everything. And again, repetier host still works with it. Must have something to do with how it sends and receives commands. I'll hit up the actual email support like you suggested. (I figured I would have gotten a faster response here.)

I typed on this night before last that I was having the same problem. V4 installed, would not connect, checked flow control and baud rate, still no work. I downgraded back to 3.x and it connected perfectly, first shot. I emailed support yesterday and still have not received a reply

O talked to support and they said change the flow control back to the default. It worked for me and in am printing right now
