Using a 7i92t as replacement for a parallel port

Category: Driver Boards

Thank you unknown, that's very important information. I noticed that the card came with the W1 and W2 jumpers in pull-up mode. I moved them to pull-downs. 
Hardware-wise, I'm closer to my goal. 

Now, regarding software configuration. I used pncconf to generate a configuration using 7i92t_g540d.bin, since pncconf does not show the firmware that corresponds to what I need (in the stepconfs, dir and step are swapped). The firmware that matches the lathe is 7i92t_benezanx2d.bin.

Can anyone review my hal and ini files (attached) and tell me how to handle swapping the dir and step pins? After the hal is corrected, I assume I need to flash the benezan firmware, right?

Also, if someone can suggest how to clean up those files... I only need to control the pins I mentioned when I opened this topic (see top).

I may need to come back later about the PID stuff and the scale calculation. One of the issues I found in pncconfig is that the pitch can only be a value >= 1, I needed to enter a value of 0.8 mm/rev.

Error when saving postion offsets in the offsets tab

Category: QtPyVCP

Hey peeps. I have searched the Internet and cant find an answer. I have hooked up absolute encoders and when I try to save the current position G54 on the offsets page I get the error bad character a used. Any idea what's going on? I can losd the table and clear it, but cant save it. 

Not sure if this is a pb thing or a linuxcnc thing. I read that when himing for the first time with absolute encoders i need to save the home position by zeroing the axis and saving the cirrent position to the offsets tab.

Many thanks

Control linuxcnc by FT sensor (external force)?

Category: Advanced Configuration

I tried Jogwheel to move the robot and encountered a problem. If I move a single axis, it's good, but if I move multiple axes at the same time, it won't be smooth because they are not synchronized.

Flex Gui preset buttons

Category: Flex GUI

I have some override preset buttons for  feed_percent_ , rapid_percent_,  spindle_percent_
I'm still doing simulation.Only on a MDI axis movement or run a program, if one of those buttons pressed, it doesn't release 
for about 5 seconds, and the DRO doesn't update for the same period. Otherwise it switches instantly. There is no plotter at the moment.

and more:
_To display 'rotation_xy_lb' (returns float), i am unable to set precision to 3 digits. Depending on calculation, it is filling the label.

_Is there something similar to bool label, but to display a .png? For spindle is on, or spindle at speed and others it would be a good alternative to text.
