Hi @SandervG, thank you so much for the warm welcome and feedback. We have only tried printing with Tough PLA and Ultimaker ABS so far. I do not think it is an issue with the filament since I tried printing with the same filament using other printers, and they came out fine. We don't think the issue is with the hot end either since we swapped to a new hot end and the outcome is still the same. I also believe the flow sensor is enabled - I haven't received an ER43 error code that was saying otherwise. So far, the printer has outputted error ER52, ER61, and ER63. It came to a point where the printer kept giving an error and asking to reboot on startup. I manually removed the filament by turning the printer off, cutting the filament at the insertion point, and gently pulling it forward/out through the Bowden tube (ER61 - Material Station failed to unload material – Ultimaker Support). We have since been using extruder 2 to continue printing operation – it seems that the problem is isolated to just extruder 1 and its subsystems. I will try taking Carla's advice by printing on extruder 1 without the material station. However, if the issue is in regards to the material station, do you have any advice on how to go about troubleshooting it? Thank you, Francis

My company recently bought some UMS5 pro bundles, and we believe that the material station is causing some issues. Currently, when filament is inserted, there are several instances where the hardware inside the material station would "dig in" on the filament without actually extruding it. This resulted in filament powder being scattered inside the bowden tubes. I haven't been able to get a successful print due to numerous errors/blockages/gears digging into the motor, and I was wondering if anyone had any advice on how to troubleshoot the material station. We believe the root cause of these errors are because of the decoupler or a motor inside the material station. Is there anything I should take into account before I remove the side panel of the material station and start poking around? As a side note, I submitted a support ticket to UM but they're taking forever to respond and hence this post.
