Thanks for the reply.
Start print. check temps via tune. both nozzle and bed reports room temp, no change.
stop print. set temp to 200 and bed to 60, both heat up and report progress.
start print. progress bar sits at initial position, nozzle and bed naturally cool.
I will check cable connections tonight and report back
Sorry for the delay in following up. Restarting Cura does not reliably connect to Octoprint. It seems to be a lottery about when and whether it will work.
[Edit] I've noticed that sometimes if I wait a while (minutes) it will eventually connect. In addition, once it has connected, it will sometimes say "Sending data to Octoprint" but show now progress until I click cancel and try again.
One more thing: sometimes after a print, the Octoprint web interface claims the print has finished, but Cura thinks it has not, and so does not allow another print to start. All this implies to me that the comment in the previous post (Octoprint is still telling Cura it is not ready) sound like it is the case.
You are right, but I tried to measure to avoid those bulges. My failure was, that I printed nearly every test object with the "Fast" profile and there the accuracy is not as good as in "Normal" or "Fine".
With the normal profile (0.15) the accuracy is quite good and I just have +/- 0.2 max. difference to the actual dimensions which is good for the 3D printing technology I think. Just in inner holes there is more difference, but I read that this is also "normal" and I have found some options to play with to optimize also the inner holes.
The surface looks pretty much like PLA although printing is not exactly as easy as PLA, although would say it's easier than ABS. I did experience little warping (used adhesive spray), although not that much. The object is pretty straight so not sure how overhangs / more complex parts would go. I printed with a printing temp of 240°, build plate temp of 90° and print speed of 60mm/s. Added some pictures of the print (you might see a crack in it which has been there from the start, some screw was little too big for the hole but felt it was still ok and not worth reprinting).
