Hi, I had to replace the hotend assembly on my R2 recently due to some filament that was stuck inside. Since the replacement, I'll randomly get the following error "Connection Interrupted, please reset the connection to the printer controls. If error persists, please call customer service and report: Heating failed, system stopped! Heater_ID: 0. I would instantly attribute this error to the new hotend assembly, but the thing is that it heats up half the time without the error, and can even get around 15 minutes into a print without failing. It can heat up to the point where it can load and unload filament with ease; it seems to just have trouble staying at the operating temp. I apologize for any incorrect terminology, I'm not as well versed with 3d printers as some others are on this forum.
