Received my printer two weeks ago, everything in the package (touchscreen, heatbed). Assembled it, did the leveling stuff and printed the rocket. One thing I noticed was the power plug. It’s not very tight and depending on the rotation the printer turns off, but I got used to this. As everybody said it is quite slow but the print of the rocket was good at all. I updated the software described by @foo bar. I thought a good idea is to print the wide known calibration cube (Thingiverse) to check the dimensions. Very soon i noticed a big layer shift. I thightened the belts to fix it, the result was better but by far not as good as the rocket. The next thing I did was printing two models from Thingiverse. A small catapult and another rocket. Guess what: the layer shift was greater than ever before. Checking the belts again didn’t fix the problem. After looking all the comments I found the hint with the robin_nano_cfg.txt > DEFAULT_ACCELERATION 11 > DEFAULT_XJERK 8 > DEFAULT_YJERK 8 This helped a lot. The models came out ok. Not perfect but I think we can’t expect too much. I’m planning to change the values to find the best results because the speed is again slower. Maybe I will upgrade to the other firmware from @foo bar?! One thing to say: After just 2-3 times inserting and removing the SD card, a small metal piece fell out. The result was that the card will not ‘click’ in any more. Because if this I contacted the support. The response was quick. they wanted a video of the problem, fine. They told me that the main board has to be replaced, but I will get a complete new printer. Because of the long delay, the bad communications I was a little skeptical. Surprise! Today (after 5 days) I got another Amazon package with a brand new printer. Sorry for the long post but maybe it’s interesting for somebody of you.
