Yes. For the past few weeks I´ve had the Gecko´s fault for no reason. Now, in hindsight, that should have been a huge alarm flag. I thought maybe the backlash on LinuxCNC which steps faster than the max step rate may have somehow caused that since I was doing a lot of Z axis passes and suddenly losing position as the drive faulted. So I lowered the overall speed of the axis and the problem seemed to go away. Until yesterday just as I was running a check on the paths with the tool clear of the work. Now I know that if the alarm LED goes on to pull the drive and clean connectors etc. Assuming I buy a replacement Gecko if this one can´t be repaired.
