I recently ordered a Robo 3DR1 Plus with the new MC 10 tablet with it. The Tablet simply cannot finish most of its prints. The only thing it can print consistently is the calibration ring. It constantly crashes on my projects with no regard to difficulty or file size. Sometimes it crashes the project into my print, sometimes it fails to even start. It fails to preheat my extruder or bed at times and some times it just stops mid pre heat for no reason. The printer often pauses during a print for long periods of time, then starts back up again, with no apparent drops or spikes in extruder temp. When it does crash, (most of the time after a long pause) it often leaves my extruder on while the rest of the program returns to the home set up where you hit the print button. Last night the nozzle burned the end of my print black and now my extruder nozzle is all blackened and nasty looking. I have no idea if it caused any damage to my Robo. Right now I am too frustrated to continue using my controller. I don't want to damage my machine or burn my house down with continued use of the MC 10. Another issue I have is the tablet seems to be somewhat cheap in construction with USB and power connections that are more worthy of a 50 dollar tablet than a 300 dollar one. My USB sits in it like crap, and I can tell you now that this machine will not stand up to repeated plugging and unplugging. The power cord is ridiculously short and loose, and has actually fell half way out of the socket of the tablet once during a print. The screen protector (if that is what it is) has more bubbles in it than it should have. The MC 10 also took a number of restarts and about two days of fiddling with it to get it to even update. In fact, for it to even run I have to restart it often or it will just simply continue to throw all kinds of buggy behavior out. I tried calling MatterHackers (to have another question answered about the Robo build plate interface) but I have never received a return call regarding a simple question that Robo cannot even answer regarding the MC 10. I am super disappointed in this product. I was really excited when this first came out, but now I feel like I have just paid for a product that was not tested well, and now I have to find all the bugs. I don't want to do this for 30 days just to find out I can't get my money back or get it to ever work correctly either. Reading through all the posts here and from what I have garnished from the few others who have this product I have surmised that the MC 10 is not yet ready for prime time. Maybe I am wrong and I just got a junked MC 10 that slipped past QC. It happens. If I can get this resolved I will definitely reflect that in an update to this post. At this point point however, it would seem that the SD card shuffle would be faster, simpler and safer. Right now I can tell you MC 10 most likely NOT the future of my printing and that's too bad. I really want this thing to work for me. It has so many cool things going for it, but I don't have the time to deal with three tries per print or the money to burn for a half of a spool of PLA for one small project.
I guess that makes me curious if anyone has had their MC 10 live up to its advertised claims of awesomeness? Is the older smaller version of the MC tablet as buggy as the 10? I have read a few glowing reviews, but they seem to be the minority. Even on the Robo forums they say the first thing you should do is ditch Matter Control. I figured with the 10 most of the problems would be sorted out.
Also, how does MatterHackers deal with refunds or replacements when the unit is included with a printer like mine did with the Robo 3DR1 Plus? Do I have to get a refund or new unit from Robo?
