Cura 12.12 with RAMPS 1.4 connection issue

[pretengineer 0]

Hi,

I've recently downloaded Cura 12.12 to use with my RepRap Prusa but I can't get it to connect. When I click connect in the print dialog, it goes from 'Machine State: Detecting baudrate' to 'Machine State: Error: No more baudrates...'

I've tried setting different baudrates in the firmware but no luck. I've been using Slic3r and Pronterface for the past few weeks with little to no issues.

I'm using RAMPS1.4 and Sprinter software.

Any ideas on a solution?

Could you post the error log?

yet again another 'cannot connect error' with the new software, surely something is amiss?

I should mention that I had this same problem with a RAMPS 1.3 board and a different Arduino as well.

Odd. I've never tried sprinter myself (as we use Marlin), one of the things that could be it is that it takes a while for sprinter to be start-up. If you use pronterface, how long does it take to connect? (Pronterface uses very long timeouts, while those of Cura are pretty short)

 

[pretengineer 0]

Pronterface connects almost instantly. I have to swap out my heatbed thermistor for one that Marlin won't read as absolute zero so until then, I'm stuck with Sprinter. I've only realised there's a new version of Cura available so I'll upgrade and see if that helps.

Did the upgrade fix it? I know when I had trouble with my Gen 6 connecting, once I upgraded to 13.03 I believe it was Cura connected just as well as the others. Before I upgraded I was having the same issues you are.

I haven't had the chance to try it with the upgrade, I'll post results at the weekend when I give it a try.
