Hi, so I manage to connect my xbox controller. I map begin probing on the A button. I’m using the autoprobe. Longmill 2.5, gSender1.5.6 When I start the probe from the gSender interface, it works perfect but when I use the controller, the tool goes down and I get a message Error 2 bad number format. Any advice? ---

@JMenard Welcome to the group! Did you look at the console to see what input the controller produced? It’s just a shot in the dark but I’m wondering if maybe the controller button ‘fired’ more than once or something along those lines. Comparing the console output from both ways of starting a probe might provide some insight into the issue. EDIT: There might be a problem with shortcuts. Basing this on: > [@Go To Corner shortcuts generate soft limit alarm code 2](https://forum.sienci.com/t/go-to-corner-shortcuts-generate-soft-limit-alarm-code-2/25382): > > Following my other post on using shortcuts, using the four Go To Corner shortcuts (Alt Ctrl 1, 7 ,9 ,3) generate alarm Code 2, soft limit. Using the icons on the GUI works fine. and > [@Probing shortcut generates alarm 2](https://forum.sienci.com/t/probing-shortcut-generates-alarm-2/25379): > > The shortcuts for probing are a little confusing so I had to try them out to see what actions they did. Looks like these are the actions for the three main shortcuts Begin probing: Confirms the circuit check and starts to probe Confirm Probe popup: Doesn’t appear to do anything Display Probe popup: Starts the probing cycle and displays the circuit check popup But when using the shortcuts and doing “Shift P” to confirm the circuit check, i get an “Invalid Line” error: The following lin… Those both mention Alarm 2. Did you get Alarm 2 or Error 2? ---

Thanks @_Michael I will check the console output this weekend and compare them. The message says Error 2 ---
