About 15 years ago, I was given a Phoenix GS CNC router/engraver with outdated electronics. I replaced the electronics with Spark Concepts CNC xPro V3 controller and three Steppersonline DM860T drivers. Today, I found out that the Y-Axis was not working properly. The Y-Axis had a mind of its own - sometimes it moves in wrong direction. I checked to see if any wires are loose but no wires are loose. The LEDs on the CNC xPro controller are red instead of green and the LEDs on the drivers are green. I can't buy Blackbox32 because the stepper motors require 48 VDC. I remember seeing a list of CNC controller boards that have ESP32 chips on them but I can't find the list. There is Drawing Robot at Instructables but I'm not sure if it will work. I saw 6x CNC Controller for FluidNC (integrated ESP32) but I'm not sure if it will work. Drawing Robot - Wifi Bluetooth USB CNC Shield Grbl_Esp32 : 25 Steps - Instructables 6x CNC Controller for FluidNC (integrated ESP32) from Bart Dring on Tindie Any suggestions?
Sounds like the symptoms when only 3 of the 4 motor wires has contact throughout - probably just a break inside a cable at a strain point (inside insulation, replace cable) - see known symptom in section 1 of docs:blackbox-x32:faq-identify-motor-coils [OpenBuilds Documentation] (applies to all stepper motors not only BlackBox) A length of cable much cheaper and less disruptive as a first quick test
