I installed a J Tech laser last week on the left side of my spindle last week. I moved the limit switch on the X axis to account for the four additional inches when the laser is attached. In jogging the machine, I forgot about the new switch position and hit it. Alarm went off and I reset it. Now, when I use the jogging feature, it moves in turtle speed. I couldn't figure out why, so I got the bright idea to uninstall/reinstall OB Control. It didn't solve my issue... homing sequence now moves in turtle speed and tries to home to RR corner instead of LF corner. Same issue using Lightburn. Any help resetting things would be appreciated. Thanks all, KM
Restore your last good Grbl Settings backup. If you never took a backup, manually work through the Grbl Settings checking Steps per mm, acceleration, max rate, homing dir, etc. See the Grbl Wiki for more info
Hi Peter, thanks for the reply. Unfortunately, I did not have a backup of my grbl settings. So, after searching for grbl settings, I used this as a guide. Now, the spindle will not move in any direction. At this point the machine is completely unusable as I cannot move the spindle from its current location. Although I've r/r the control software, it did not do a fresh install, it kept my inch and dark mode settings which makes me think that there is a file somewhere that doesn't get deleted and is being referenced by the control software. Suggestions at this point?

Do you have a BlackBox 4X or a BlackBox X32? X32: $4=0 4X: $4=1 That is very slow - compare that to our machine profiles (for example a LEAD1010 is set to 2500mm/min and that is also extremely conservative) Super low. LEAD1010 profile sets it as 150mm/sec^2 and again, that is a very conservative default setting Not sure what machine you have, but those haven't been changed from default Probably want that as 10mm instead or you won't clear a typical lever switch You also didn't say which machine you have, but if its one of ours - use the Select Machine > Select a profile from the list instead
I have a Blackbox 4X and a Lead1515 machine. I made the changes you listed, the axis is moving again. You referenced a Lead1010, what do you recommend for the Lead1515? I'll make a backup of the settings in case something else goes wrong.
