What was the result? Were you able to start the machine?

Hello Andypugh,
I had same error.
If I deleted "n_rows" and "n_colums", it can run, but layout is not as beautiful as design.
Can you update ?.
Thank you.

2. Run a tool orientation algo for a & b axis. I think using A & B is simplest. This then solves smoothing for A & B axis toolpath.

This would only work for a machine with XYZAB kinematics so the algorithm needs to be adjusted depending on the type of machine kinematics used in the particular config as solving for AB angles will not work for XYZAC (C axis instead of a B axis) or XYZBC (C axis instead of a A axis) machines.  

Tonight i went to the production machine with a hard-drive for testing hal-core.
After figuring out how to setup hal parport and run posix realtime etc for a few hours,
i managed to run the machine on hal-core.

I'm still a bit confused seeing that tool motion still decelerates to a full stop after each segment. I guess feed rate blending over consecutive feed moves is a separate problem to solve but given the importance of constant tool velocity in CNC trajectory planning I'm wondering if you have a solution in mind for this yet. 

I think a look at your hal and in files will need looking at. And a drawing of your actual wiring.

Try the parallel port tester as mentioned at the beginning of this thread.
Try it without the breakout board connected, if everything is fine try again with the breakout board connected.
BTW what voltage are you powering the breakout board with ?

N40 G54

Are you sure you are also zeroing the Z offset in G54?

Have you tried starting your config from the terminal to check for error messages in the output?

Hello, I have a question. I want to emphasize that I am new to LinuxCNC! The spindle has separate oil lubrication. I want the pump to not run all the time. Only when the spindle is rotating. A pressure sensor is installed.
I want to do before the spindle turns to turn on the lubrication pump and wait for the enabling signal from the pressure sensor. When true to rotate the spindle. If during rotation the signal from the sensor changes its state, it is not true to trigger an alarm. What is the right way? Is there an example? I'm sorry, but I couldn't find a similar topic.

After playing around with it forever, I was able to reinstall LinuxCNC from scratch and loaded the driver (the parallel port card already seemed to be enabled).

I tried configuring as:

Pin 1 = EStop On
Pin 2 = A Step
Pin 3 = A Dir
Pin 4 = Y Step
Pin 5 = Y Dir
Pin 6 = Z Step (I think you swapped Pins 6 and 7 in your writeup)
Pin 7 = Z Dir
PIn 8 = EStop On
Pin 9 = Estop On
Pin 14 = EStop on
Pin 16 = X Step
Pin 17 = X Dir


I'm not sure what Enable is supposed to be on LinuxCNC. In order to send manual commands from LinuxCNC it seems like I have to toggle the Emergency Stop and then Machine Power.

That said, when I went to check the outputs on a scope, it seemed kind of weird. Pin 1 was high all the time, but Pins 8, 9, and 14 were low. I tried putting "invert" on all 4 pins, and they all read low. So I suspect there is still an issue outputing out of the parallel port.

This time, unlike last time, the only axis that "worked" was Y. Previously, with the default setup Z clearly worked perfectly (possibly with the opposite orientation). When doing Y+, the motor put out a motor-like hum, and I saw the leadscrew turn, but it didn't seem to move super smoothly. When going the opposite direction,the leadscrew moved around faster, in the opposite direction and with some awful noises.

Hello.
Whas does this python script?
Automatic lubrication via automatic lube pump?

Forum member Kam visited with a new (old stock) 7i96, got the same packet loss problem.
Tried Windows laptop and Linux laptop, with different cables, all fail.

I note that my install shows as LC2.9.1, not LC2.9.2 as listed in download page.

Replaced LC2.9.2 (1) SD card with a new SD card fresh Imager burn of my old image of LC2.8.4, SUCCESS.
2950 packets for 0% lost.

Both the LC2.9.2(1) and LC2.8.4 were official downloads.

LC2.8.4 loads and opens AXIS.
But still grappling with the Custom Hal to get my E-Stop control working.

Basically back to where I was prior to trying to get WiFi operational.

Now, some more investigation of why my LC2.9.2(1) fails.

Stay well,
John.

Comp is installed. .C and .H files are in the same location as the HAL. unsure if i need to save into where the comp installs. I couldnt use the makefile that was in the original code to install it all.

Am having a problem, probably user error but unsure where to look.

We have a touchplate on that we normally use with M6 tool change. This assumes that the work origin is at the waste board, and this appears to work Ok.

I regularly do engraving, and it is easier to touch off to the top of the work manually.
The design is in Fusion360 and the post processor is LunuxCNC one unmodified.
To do this I just run the post and edit the file to remove the M6 line.
I then jog over the work bring the tool down to touch the work and click on the Z (gmoccapy) and select 0 offset ok.

Everything looks Ok. I know the clearance height is 15mm. If I single step, which I always do because of this problem, then it appears to reset the Z to an apparent random number after the spindle start and when it positions  over the the work i.e. when it positions over the start  of the plunge i.e. N55 below

If I go back and re-zero the Z then it works every time. Sometimes the Z changes to a "rational" number like 55mm (total Z travel is 190mm).
Other times it is over 600. This only happens occasionally, but always works the second time.

This is a shared machine in a makerspace, but this is happening from a clean start, so unsure if it is related to any previous job.
Have not seen any issues when using the M6 macro.

Many Thanks !

JLC yes. No one else is even close to that cheap on large nylon parts.
