-
Ensure the power and signal cables on the VFD match below
VFD Display reads r00.0 or f00.0
If the display on the VFD (the power box for the spindle) reads r00.0 or f00.0, there is a lack of communication between the control board and the VFD.
Please do the following:
- Download the file for your machine. Ensure to download the correct file.
- Altmill - Sienci_spindle_configuration_SLB-EXT.gcode
- LongMill - LongMill Spindle Configuration (SLB Controller only).gcode
- Open gSender and run the attached setup code. This will set all EEPROM settings to what they should be.
- Power cycle absolutely everything. Turn off the VFD and the controller. Close gSender
- Turn on the VFD first, then the controller, then connect to gSender. Ensure the VFD is plugged into the back of the controller above the power switch.
