E-stop switch failed; unreliable contacts
- 2018/09/02 - replaced with premium Sprecher & Schuh
X-axis stepper coupler failed
- 2018/09/12 - replaced with similar spiral wound-style as temporary; ordered lovejoy-style
Z-axis found slipping/losing position
- 2019/03/xx - replaced Z-axis stepper motor coupler with lovejoy-style
2019/05/xx - X-- & X++ limit switches moved outboard
- collision possible between gantry riser brackets and z-axis now --REQUIRES RESOLUTION
2019/08/xx - X-axis coupler found spinning on ballscrew end
- one set screw found missing, re-tightened remaining set screw
2019/09/10 - B-axis (Y-axis slave) home proximity sensor found damaged, homing procedure not functional
- 2019/09/14 - replaced proximity sensor [2]
2020/03/05 - Spindle VFD fault "EoCn" - overcurrent on longer-running job (30 mins?) - Mark
- unresolved
2020/03/11 - some features of Mach3 not functioning correctly
- STEP JOG mode non-responsive; breaks Mach3; requires restarting program
- MDI input non-responsive
- Single-block mode ignored
