Gmoccapy 3.5.0 - opinions needed

Category: Gmoccapy

G-code Properties is a nice feature, witch I would like to see ;-)
Even knowing that the values shown are not correct in most cases. But they do give a first impresion!


The question is only how to handle the embedded tab location "box_tool_and_code_info" (linuxcnc.org/docs/devel/html/gui/images/...py_embedded_tabs.png).

Should that replace the complete notebook with both tabs or only the content within the first tab?
The first would be better for backward compatibility but the latter would make more sense.

get a bad character '/' on probe macro

Category: General LinuxCNC Questions

ok so i started writing some macros, to test and they all work so the fusion ones i downloaded must be sending the char or returning something wrong

i will keep working on it

Seems to work on axis (2.10):

 


This file gives me this. Still an emtpy tool list:
G-code properties: {'name': 'gmoccapy_2_tools_with_cutter_radius_compensation.ngc', 'size': '1234 bytes\n93 gcode lines', 'g0': '58.000 mm', 'g1': '327.121 mm', 'run': '25 Seconds', 'toollist': [], 'x': '31.000 to 69.000 = 38.000 mm', 'x_zero_rxy': '31.000 to 69.000 = 38.000 mm', 'y': '31.000 to 69.000 = 38.000 mm', 'y_zero_rxy': '31.000 to 69.000 = 38.000 mm', 'z': '-252.287 to -221.287 = 31.000 mm', 'z_zero_rxy': '-252.287 to -221.287 = 31.000 mm', 'machine_unit_sys': 'Metric', 'gcode_units': 'mm'}

Also a bit weird that it has the tools 0, 3, 1 in the list in Axis, but there is only T3 and T1 in that file.

I prefer the progress bar under the g-code.


Me too :)

About the Icon it's just a matter of taste IMHO, I do not like the black and white icon, but I also see the need to reorder the button to reduce mouse movement.


We can also have this icon in yellow, no problem ;-)



About the File Chooser widget, I was thinking for long time about a Widget designed like the Midnight Commander but unfortunately I have not even started to write the first line of code .


You mean that one that looks like the Norton Commander, so text based only?

Carousel with analog servo drive

Category: Advanced Configuration

I tried using the speed mode, but it didn't work. So I went back to the original control. By manually rotating the carousel, I determined the number of pulses between the individual pockets. The automatic tool change works quite well, sometimes there is just a problem with homing the carousel. If the carousel goes to the same side at the home position, it is fine. However, if the carousel goes to the other side after homing, there is a small error in the position. I tried using rotation in only one direction, but there is another problem that the error in the number of pulses between the individual pockets adds up over time.

Here is short video from tool change.

RPi 5 with 6.12 PREEMPT_RT = Using POSIX non-realtime

Category: Installing LinuxCNC

Hello @cornholio:

I do understand some of the things you are saying. 

I'm not a LinuxCNC'er so please bear with me.

A start might be to enumerate types of users as I see them:

Gold users just want to get something done (say make parts for a space station). Their CNC machines are already supported by LinuxCNC. They would appreciate a working version of LinuxCNC. Once they get it they probably will not change it over time unless they need to support new devices or new features.

The key here is that installing and getting LinuxCNC running should be as easy as it is to get Raspberry Pi 5 or Ubuntu up in the first place. (I'm not sure if my experience getting RPi5 up is similar to getting RPi4 up but more on that later).

If a newcomer can not get a version going enough to run say a "Maslow" machine (please Google "maslow cnc kit") then work still needs to be done.

Silver users/developers know and contribute to the LinuxCNC GitHub repo. The users have absolute control of the repo and the CNC, sysgen and testing features merged into it.

Bronze users/developers know and contribute to the Linux GitHub repo. The users have absolute control of the repo and the OS, sysgen and testing features merged into it.

The question comes: How to manage the need for support between Gold, Silver and Bronze users. I'm not sure of a solution here but I believe some solution will arise.

Tests should exist that (all) developers can run and get understandable results from. The only issue should be coverage at a given point in time. Hopefully the more tests you develop and manage the better off everyone should be.

I realize some of the above exists. It just needs to be pulled together.

An observation about configuration files: I think they may have gotten a bit out of hand.

I believe plain text files are easier for users to work with than XML but, a coherent "system build, installation and configuration" facility may be easier to develop and maintain if the configuration is rationally represented by some data handling facility (not a DBMS).

Please let me know your thoughts up to this point.

Many thanks,
Tom
