5i25/7i76 analog spindle control on Lathe spindle

setp near.0.difference 8.33333

In this case means you have to be within 8.33 RPM of the
commanded RPM to make spindle at speed true

Pi4b and Pi5 users - What should go in a 2.9.3 image

Category: Installing LinuxCNC

Well I tried our image first, and got this:
 

That was written with rpi-imager without error.  Note the bootloader date (2022).  So then, long-pressed shift and installed the latest RaspiOS. In that, did a sudo rpi-eeprom-update to see what firmware versions were in use:
 

So looks like there are still firmware updates. So then issued a sudo rpi-update, which after that completed, was verified:
 

So then the SD card was re-burned with our image, and that now boots, woohoo!  Thought I'd share if anyone else experienced this.

5i25/7i76 analog spindle control on Lathe spindle

Category: Basic Configuration

What is the line
setp near.0.difference 8.33333
supposed to do?

After changing the ENCODER scale, I have At-Speed indicator all the way up to 1000-1100 rpm. I looked up the motor and it is rated at 3200 rpm at 110 volts. It looks like I am getting a max of around 2475 rpm.

Is any specific software mode required on the 7i97T for the MPG inputs to work? I didn't see any mention of this in the manual.

Thanks,

To have additional step/dir outputs on P1 you need to change
the default firmware on the 7I96S to one with additional stepgens.

For the common Sainsmart "Mach 5 axis CNC" breakout, you would
use 7i96s_5abobd.bin. This adds 5 more stepgens plus 1 more encoder
and 1 more PWMgen.

To use pncconf with the added stepgens, you would need to:

1. Update the firmware
2. use pncconfs discover option

Mesa 7i96s firmware for Index (2.9 release)

Category: Advanced Configuration

If you want just one stepgen/encoder index on the 7I96s's built in encoder
interface, use 7i96s_esdi1.bin. If you need more, it depends on where
you want the index pins to connect. The 7i96sd_esdid.bin firmware
puts 3 stepgen index pins on the 7I96S encoder A,B,IDX inputs
(losing the encoder)

[QTDragon] blocking in hal_manualtoolchange dialog

Category: Qtvcp

It is possible to have a custom dialog. I haven't done one for tool dialog but see no particular problem. It would, as you suspected, require a custom handler file.

But I don't think it ill help you. The dialog blocks because linuxcnc is blocked. Unblocking the dialog will not unblock linuxcnc.

You can not call MDI commands at tool change unless it's incorporated into a remap.

How did you install linuxcnc? What linux version did you install? Looks like You are not running Debian 12. Python 3 is included in Debian 12
I would recommend you use the image on the Linuxcnc downloads page
