FLSun QQ Problem

Thu Sep 27, 2018 5:22 am

I am trying to get my FLSUN QQ printer working with S3D. It's communicating okay, but after a few 10's of seconds it stops moving, showing the following in the message window:

READ: echo:busy: paused for user
busy: paused for user

It doesn't stop moving on each of these messages, but it does eventually. And I can't make it resume. I can produce a couple of minutes of print of the first layer but it then stops and cannot be restarted.

In amongst this are print head physical moves which arern't part of the STL design. So I suspect the movement control is getting some garbage instructions coming through.

I'm not actually doing anything to trigger the "paused for user" message - it just seems to be random. I've tried setting hardware and software flow control in case the message buffer is overflowing, but that doesn't help.

This exact same setup is working reliably with Cura, so obviously something about S3D is quirky.

I have similar issues with Simplify3D and my FLSUN QQ-Pro printer. I don't see any solution to your post.
