I have 2 Robo3d R1+ printers at work. One of them works just fine, but for the other one... I have never been able to get the bed leveling correct, and have resulted in just using a dial indicator to level the bed. I finally had some time today to look more closely at the problem, and the only thing I notice is that the bed flexes a great deal on the left hand side when performing the G29 auto level. As a result, I think this causes that side to scrape the bed because the software thinks it sits lower than it really does. Could this be the reason the bed leveling is off? If so, is there any fix for this or something below the glass to look for. I looked and didn't notice anything, but I didn't know what to look for. I did a G28 and then the M119 see if the switches were being depressed, and they are. I know the bed is pretty level to begin with, the switches are in the correct orientation, and I use a dial indicator before every few prints. If there is no fix, can someone recommend an easy replacement (not another Robo3d bed as the last one I had shipped was cracked upon arrival) such as a piece of aluminum (how thick) and a new heater that's compatible (I know it's 12v), but what would you guys recommend? At a loss here. I really hate having to use the dial indicator all the time and adjust the offset for this machine. Thanks in advance, you guys are awesome.
