Hey Sid,
do you mean settings inside the VFD, in order to suit your spindle?
If so, this should be found in your spindle manual.
EDIT: Do you mean the settings in 8.Creating a Custom VFD Program?
If so, you should not need this, since under ‘tool-type’ in Onefinity CNC Controller’s Tool Configuration Tab, you should be able select “V70”. Did you try it with this?
EDIT: I don’t run the Onefinity CNC controller, however by looking at the source code of the Onefinity Firmware 1.0.9 (unlike Buildbotics Firmware v0.4.14 or higher), it seems that the ‘V70’ VFD is not offered under ‘tool-type’, can you confirm this?
At least the ‘V70’ entry is not found in Onefinity’s Firmware file src/resources/config-template.json nor in the file src/pug/templates/tool-view.pug. However it is well present in the source:
# 1.0.9/onefinity-firmware-master/src/avr/src/vfd_spindle.c
const vfd_reg_t v70_regs[] PROGMEM = {
{REG_MAX_FREQ_READ, 0x0005, 0}, // Maximum operating frequency
{REG_FREQ_SET, 0x0201, 0}, // Set frequency in 0.1Hz
{REG_STOP_WRITE, 0x0200, 0}, // Stop
{REG_FWD_WRITE, 0x0200, 1}, // Run forward
{REG_REV_WRITE, 0x0200, 5}, // Run reverse
{REG_FREQ_READ, 0x0220, 0}, // Read operating frequency
{REG_STATUS_READ, 0x0210, 0}, // Read status
{REG_DISABLED},
};
which would translate to the following settings for 8. Creating a custom VFD program:
| Command | Address | Value | Comment |
|---|---|---|---|
| max-freq-read | 5 | 0 | Maximum operating frequency |
| freq-set | 513 | 0 | Set frequency in 0.1Hz |
| stop-write | 512 | 0 | Stop |
| fwd-write | 512 | 1 | Run forward |
| rev-write | 512 | 5 | Run reverse |
| freq-read | 544 | 0 | Read operating frequency |
| status-read | 528 | 0 | Read status |
| disable |
As for the default settings for the VFD, in Buildbotics v1.0.1 firmware, it says in
v1.0.1/bbctrl-firmware-master/src/pug/templates/settings-tool.pug:
.notes(v-if="tool_type.startsWith('V70')")

NOTE: I don’t run the Onefinity CNC controller, I just had a look at the firmware! I cannot test anything.
