### Basic Information: Printer Model: EnderXY MCU / Printerboard: BTT SKR Mini E3V3 & Creality 4.2.7 Host / SBC: RPi 4 klippy.log (plus moonraker.log and mainsail-error.log): [Desktop.zip](https://klipper.discourse.group/uploads/short-url/zdKXbePmJQO4I3QJeBid9emH66a.zip) (1.3 MB) ### Describe your issue: Everything was working fine before I updated Klipper to the most recent version. Now, I can only get Mainsail to connect to Moonraker when the printer is off. Once I power on the mainboards and restart Klipper, Mainsail times-out on “Initializing” and says it can’t connect to Moonraker. Edit: This seems like a Mainsail issue. I can connect to Moonraker via Mobileraker and KlipperScreen and use the printer normally as long as Mainsail isn’t open anywhere. What I’ve tried so far: \*Uninstalling/reinstalling Moonraker \*Uninstalling/reinstalling Mainsail \*Rolling back Klipper several versions with KIAUH ---

[manual\_stepper.zip](https://klipper.discourse.group/uploads/short-url/6a3mylzTxLNou2ybv01WSOM9Q3U.zip) (1.8 KB) @ron_swan - Drop the Python file in the zip into ~/klipper/klippy/extras. I changed ```auto def get_status(self, eventtime): return {'position': self.rail.get_commanded_position(), 'enabled': self.steppers[0].is_motor_enabled()} ``` to ```auto def get_status(self, eventtime): return {'position': self.rail.get_commanded_position(), 'enabled': self.printer.lookup_object('stepper_enable').lookup_enable(self.steppers[0]).is_motor_enabled()} ``` Which I believe was the intention in the first place. It’s a quick and dirty fix. If it doesn’t work let me know and attach a new klippy.log and I’ll see what’s up. ---

That didn’t help, unfortunately. [klippy.log](https://klipper.discourse.group/uploads/short-url/7BGhoOInvh6dez5fZw6ul5eyKad.log) (496.3 KB) ---

[manual\_stepper.zip](https://klipper.discourse.group/uploads/short-url/3kZLO5B9KgQ4LGTDLp4WTJl9GDl.zip) (1.8 KB) I caused another error by being quick and dirty, try this one, It reverts the manual\_stepper back to before the status function was added ---

[manual\_stepper.zip](https://klipper.discourse.group/uploads/short-url/7aPjLAcPIIgD8Za1MlARo32fWbv.zip) (1.8 KB) Okay, dealers choice, the previous one reverts back to before the change. This one actually corrects the issue. @koconnor - Sorry for the double tag, but I can confirm the newest update to manual\_stepper (the status function) causes Mainsail to hang when the webhooks try to get the stepper status cause there is an error. I’ve messed with my branch of Klipper so don’t want to put in a PR and have to mess with another branch and making sure I take out unintentional changes. I changed the following lines… ```auto 34 self.stepper_enable = self.printer.lookup_object('stepper_enable') ``` 45-55 ```auto def do_enable(self, enable): self.sync_print_time() if enable: for s in self.steppers: se = self.stepper_enable.lookup_enable(s.get_name()) se.motor_enable(self.next_cmd_time) else: for s in self.steppers: se = self.stepper_enable.lookup_enable(s.get_name()) se.motor_disable(self.next_cmd_time) self.sync_print_time() ``` 108-110 ```auto def get_status(self, eventtime): return {'position': self.rail.get_commanded_position(), 'enabled': self.stepper_enable.lookup_enable(self.steppers[0].get_name()).is_motor_enabled()} ``` ---

This one worked! Thanks Giggler! ---

Unfortunately, there was a defect in PR #6527. I reverted that PR in commit 4cfa266e. Sorry for the delay. -Kevin ---

Updated to 4cfa266e and can confirm the bug is no longer present for me. ---
