Hello,
I start a new thread here, as I hope to use pncconf for 7i43 with 2x7i39.
There are new options for brushless motors in pncconf, and there's support for 5i20+7i39. But not for 7i43.

This is because linuxcnc has not released any 'official' firmware that supports the 7i43/7i39 combo.
If you find BIT and PIN files I can make the XML file that PNCconf needs.
I warn you that the brushless motor config stuff in PNCconf is un-tested ( I have no hardware to test with)
so surely there are some bugs lurking. But I would love a chance to test this.

There's a
thread
on the list
This is the firmware
www.cutting.lv/fileadmin/user_upload/SVST4_4_7I39.BIT
www.cutting.lv/fileadmin/user_upload/SVST4_4_7I39.PIN
and this is at least partially tested config
www.cutting.lv/fileadmin/user_upload/7i43-big.ini
www.cutting.lv/fileadmin/user_upload/hm2-servo.hal
I already have 7i43 and 2x7i39, motors and encoders expected very soon.
So I'm ready to start testing pncconf

already found a bug. You can't set the 3pwm base frequency.
I pushed the fix.

The 3pwmgen needs some setup exotica to work with this 7I39 config
(this is an odd config with stepgens added for a single customer)
1. The 3pwmgens fault-invert must be set with this config (this is config specific)
2. For all 3pwmgens driving 7I39s, the deadzone should be set to 0 as the 7I39 has internal deadzone generation
