I thought ADm1N solved this with the c_pos_sync component?

The problem in spindle mode is, that the cia402 pos-fb is mapped to joint motor-pos-fb, but joint motor-pos-cmd is fixed. So joint f-error increases over time. Now I'm not sure how to solve this problem, cause I can't manipulate joint motor-pos-cmd. One way would be to freeze joint motor pos-fb, this way there is no f-error and track the movement to set an offset. But I can't figure out how to solve this, without writing to joint motor-pos-cmd.

The following error should also be a problem for aDm1N. But I assume it is less important, cause he only has 8000inc/rev, where I have 131072inc/rev, so the error adds up much slower. This would also explain FERROR = 1000000 in his ini.

Whats actual hardware do you have?

It sounds like a 7C81 and one 7I78.

It that case is might be simpler to use something like a pncconf 5i25/G540 configuration
as a starting point as that would al least let you setup the PWM spindle in pncconf.

In general, if you have the correct firmware for the daughtercard, the pins don't matter
in the hal files, what is significant is the module number like stepgen 0,1,2,3, etc.
The exception is GPIO pins.

The 7I78 encoder pins will have names like hm2_7c81.0.encoder.00.position.
7I73 MPG encoders will have names like hm2_7c81.0.7i73.0.0.enc0.position

Note that you can list all pin and parameter names when LinuxCNC is running with:

halcmd show all hm2





 

there is a duplicate addif at the beginning of the file, so it appears as the first error, I commented on that, but it also appears another type of scalemax.1 in not found

Thanks. That worked.
Before, it was unsuccessful with linuxcnc status.
Now i tested, by press the pushbutton, i can read the file by lines
 

Thanks for the answer, but I understand that I have to edit it.
Only the 7i76 card has a different pin arrangement. Otherwise, the pins on P1 are DB25. Fortunately, the pins for the first four axes are identical. I already wrote that, it works without problems.
But while the 7i78 has spindle control, serial interface and encoder for the spindle on pins 05-13, the 7i76 has an output for the fifth stepper motor, two serial interfaces and an encoder on the same pins. That encoder is labeled ENx, unlike the encoder on the 7i78 - it is QUADx. I don't know if it's the same.
So if, for example, I activate the spindle encoder on P1 in pncconf, will it be the same for the 7i78? And further, on connectors P1 and P2 (on which the 7i78 can be physically located), there is no option to set spindle dir, enable. I set this on P7 but I need it to be on P1. Will it be enough to overwrite the IO number and will it work?
Let me not forget, on the P7 pins it is possible to set the direction of rotation for the spindle - two pins, but on the P1 DB25 there is a SPINDIR pin which is one pin. So if I set one pin on P7 to CW and the other to CCW, will it get to the right place on the 7i78?

Voltage is set to 100 and H-t to 5.

Hi All,

I am using 7c81 board, raspi 5 with thc proma 150. I am using QTplasmaC 
The gpios and leds for UP, DOWN, Arc OK are getting connected and blinking.
However, the Auto Z axis movement not happening with thc proma 150. Attaching the files for your reference. Please help.

 
One option is MPGs, you could install two MPG encoders.

A new day, new challengesimage missing /media/kunena/emoticons/smile.png
I'm trying to configure MPG, added HAL pins, seems like everything worked out. But there is a problem I can't solve. When MPG is activated, it is still possible to change the increments of movement on the screen. It would be great if this widget could only display the selected increment without the ability to change it. And when MPG is inactive, it should be possible to change the value on the screen again. But I couldn't figure out how to do it.
