Hello all, I’m new to C&C and have not been in it for more than just a year or so. After having a successful year or so with my Longmill MK2 and laser I decided to upgrade to the SLB and a spindle as well as adding the sensor kit. I was excited about the fact that I would be able to have homing for the CNC as well as being able to use various workspaces that G sender offers.
The issue I’m having is that since I have set up the sensors according to the information, I could find from Scienci labs when I touched off the home button X&Y ran to the top left and stopped by the sensors, but Z bottomed out with the motor trying to surpass the stops. I immediately hit the emergency stop and released it and then went to G Sender and unlocked the machine there only to get an alarm code 11. There was a flashing bar underneath the alarm code saying, “Home machine” When I clicked on it, it just crashed z to the end of its stops again. I cannot seem to find a way to get out of this and reset everything so that I can start over again and pay meticulous attention to the instructions that I thought I had initiated in the first place. I have contacted Scienci Labs and am awaiting a response however I was wondering if anyone else has had this same issue. I have unloaded and reloaded G sender, I have cycled the SLB, I have even disconnected the main power supply of the SLB and waited an appropriate amount of time, I have disconnected all the sensors, I have tried to change the firmware settings but because of the alarm 11, I cannot make any changes in the firmware until the alarm is resolved. My knowledge of Gcode is in the beginning stages and I’m just starting to learn the various codes. I’m wondering if there is a code that I can enter in the console that would reset things to get back to a starting point.
Any feedback would be appreciated!
Thank You!
typing “$22=0” in the console will turn homing off.
Typing $RST=$ in the console will reset the board to firmware defaults (so all EEPROM values, not just homing).
One of those should fix your issue.
If it’s crashing when trying to home, you should probably test the limit pins status with homing disabled first to make sure they are all wired as expected.

Thank you very much! Ended up resetting all and will proceed to reset firmware settings.
Glad you got it working - I’ll close this now that it has a solution.
