Ok I got it now thank you so much sir. I created a new material with the material number one thats all I was missing.

Check that all material numbers called in the G-code file do exist in the QtPlasmaC materials.

It's possible to use a 7I33 and a 7I96 with a
cable adapter from 7I96 P1 to the 7I33

There's even thread on the forum about this:

forum.linuxcnc.org/10-advanced-configura...sa-7i96s-pwm-outputs

(got to the end)

Note that that is for a 7I96, not 7I96S but the same firmware can be made for the 7I96S

Using the 7I96S spindle interface for an analog servo is probably not worth the trouble for
a couple of reasons:

1. You need  a +10 and -10 supply (these are not common)
    This limit is because the absolute maximum voltage from
    SPINDLE- to SPINDLE+ is 20V

2. The spindle output only has about a 100Hz bandwidth which
    will make tuning/performance an issue


If you only need one encoder, a 7I96S+7I83 might be the most direct way

Eusurplus has 7i80, two versions in stock, no 7i93 in stock
www.welectron.com/ has none of those or i could not find them, their search is a bit fuzzy.
Be aware there are 4 versions of 7i80 if you decide to get one, no idea what the differences are as i never used it.

I am now running into this error again with every new gcode file I make and I didn't change anything. All the Gcode files look exactly the same as the one that works coming out of fusion. Qtplasmac keeps adding M02 (end program) to the first line of my gcode files. please can anyone help, what number does the material number need to match in order to stop qtplasmac from doing this?

For now, I would like to have a "go to zero" function.
Could add a function to the axis_tool_button.py file, or create the possibility of adding macros to the button menu of individual axis.
I don't know what the best solution would be, but I miss the "go to zero" function for individual axes.

Hello Tommy, thank you for your response, I have been looking at Eusurplus prices for the combinations that you mentioned, honestly it would be great to be able to use the 7i33TA board since in this I have four +/-10 analog channels and 4 encoder channels on the same board Although it would be great to be able to connect it to a board like the 7i96 since I could use the inputs and outputs directly without having to use another board for the I/O, I had even commented if it would be possible to use the analog output of the 7i96 to control a DC brushed servo since I only need one axis, if only one axis is a Double Miter Saw Machine where the only axis would be the length since the degrees of the heads are driven by pneumatic pistons with mechanical stops, so I would save a significant amount of money if I could use only a board like the 7i96, I await a response, greetings

net my-jogconvoyor-fwd     hm2_7i97.0.7i84.0.0.output-03 <= convoyor-fwd
Both lines at the end, you can not just make up pins, those must exist before connecting them:
- my-jogconvoyor-rev <<< this is OK a pin you are creating, think of it as a bus bar with that name
- convoyor-rev <<< at the end is not OK as it does not exist
-- net means "connect", so you connect the hm2_7i97.0.7i84.0.0.output-02 to the bus bar named "my-jogconvoyor-rev" and you also tried to connect the convoyor-rev that does not exist
-
Two options:
1- remove the 2 non existing names/pins and use the existing pins in your PyVCP hal file
2- rename the existing pins with the non existing ones.

Have a look at the homing veocities
linuxcnc.org/docs/stable/html/config/ini...tml#_home_search_vel
As the docs say there is trade off between homing speed and overrun.
From memory I use search_vel 12 m/min and placed the home switch far enough away from the limit switch so the axis could coast to a stop
Then a much slower latch velocity to find the home switch edge
Finally a home_offset (of about 40mm) to move close to the limit switch to maximize the machine envelope

Whilst you can use a shared home/limit switch, and this works fine where there is some weight being moved (eg milling machine table) so the axis stops quickly, a lightweight gantry might be better off with seperate switches so you can home at speed.

Following up on the spindle-at-speed idea I created a pyvcp checkbox to bypass this function. I created an or2 of the bypass and the spindle at speed signal from the VFD output to the spindle-at-speed signal. Unfortunately, it looks like Linuxcnc is using the spindle.0.at-speed pin to inhibit non-rapid moves. I haven't figured out how the bypass that pin.

If I start axis with the VFD unpowered I can continue probing using non-rapid moves forever. Then after probing the grid I power the VFD and mill the pcb. A kludge but it works.

Curiously, my touch-to-zero routine works every time regardless of VFD power state. It has non-rapid moves. Other similar touch off routines also work. Is there different intended behavior vs the spindle at speed function for routines vs gcode programs?
