I can not really connect successfully to my printer via USB
I have a Tronxy P802M (very similar to the Anet A8, but using a Melzi2.0V5 board) that seems to work fine (I just finished building, and axes movement and the integrated display work) but when I try to connect to the printer from my Simplify3D on Windows 10, I get the following:
Connected to machine!
READ: ok 0
READ: ok 0
READ: T:24.44 /0 B:23.33 /0 [email protected]:0 @:0
My other printers all connect fine.
Nope, did not change much, except now the initial connect does not work. I also tried a different USB cable and using a direct USB port as well as suing a USB2 hub...
Windows 10 - sorry, forgot the details
Okay have you set the Baud rate? I know thats an issue with slic3r. Can you see the printer under devices?
Yes, Baud rate is set the same on both sides (otherwise there are different errors). The COM port shows up under devices.
This is more suited as a comment. Moreover, the fact that he's receiving something legible (like the "T:24.44" line), means the baud rate must be correct.

The Simplify3D support site mentions to disable the "wait for startup command" option in the firmware configuration for S3D.
This allows me to make a rudimentary connection to control the printer, however e.g. during the bed levelling wizard of S3D, the connection still breaks off.
It works reliably with Octoprint. I'll consider that good enough.

Try doing this in Simplify3d and see if it works - Go to Tools --> Firmware Configuration and then click the Communication tab. Set the flow control to "Hardware flow control".
