MACH4 Ethernet Smoothstepper and output failures
« on: September 19, 2020, 06:37:04 AM »
Hi all, I have just assembled a CNC Lathe with Ethernet Smoothstepper and Breakout boards from CNC Elektronik Langenfeld. Yesterday evening everything seemed to work fine. This morning I turned on the machine again and now the ESS Smoothstepper seems to generate random output pulses for the Stepper Motors. I have already tried a different power supply for the ESS. If I disconnect the breakout board from the ESS, everything is quiet, so that noise must come from the ESS. Also, that only seems to happen, after MACH4 has started communicating to the ESS. Before the Steppers seem to be quiet. Please note, that MACH4 operation is still disabled.
Any tips ? Is that a broken ESS or is there any configuration option ?
