Calibration issue

Category: General LinuxCNC Questions

Hi...sorry for delay...thought I submitted response..


So tried smaller piece...yes..less off...

Rechecked calibration (experimentation)...was off a bit...I will keep trying.. I made this machine...used mach 3 for many years...never had a problem that you would not hear motors banging from stall ....maybe here missing steps would be silent....
Thanks for your help!

Thanks for the answer
The PIN for HAL is what I'm looking for.
The whole thing should be monitored by my comp. file mentioned above.
The spindle support is only retracted when the axle passes, and this is exactly when I want to monitor whether the cylinder is retracted.
I have no idea how to implement this in the comp. file.
I think it should be an abreage which checks whether the cylinder is really in the end bearing after the command to retract the cylinder.

But misinformation doesn't apply to the gimbernment, they can say what they like, and they have been.....funny how they start saying the quiet bit out loud after the election.
A bit of history regarding free speech Down Under, when they were writing the constitution down on the back of a beer coaster over a few beers, they all decided that free speech didn't need to be included as it was such a basic right no Aussie in their right mind would infringe on it. Look now, we're being run by a mob not in their right mind put there by voters not in their right mind.
There's no conspiracy, once the majority of the population started thinking for themselves it was deemed time to flood the west with a population that can be manipulated by superstition, the gumbernments are doing a deal with the devil thinking they'll get a seat at the table, as always when you deal with the devil he just brings his people with him.
Enoch was right, just its a different group.

M62-M65 (or likewise) from qtvcp panel during gcode execution

Category: Qtvcp

Another way that I've used is to create a couple of hal pins (an input and an output) that control the output in the gui python script. Then useing a couple of user defined M-codes to setp the value of input pin to setp the value of the input pin. This was able to allow the either the gui or the G-code to override the other like your flipflop example. Essentially the same thing, except the flipflop lives in the gui code instead of using a hal component.

M62-M65 (or likewise) from qtvcp panel during gcode execution

Category: Qtvcp

Yes, that is exactly what I'm after.

Yes, I have full control over the HAL files. I have actually got it to "work" decent, but it's a bit ugly. I convert both the park and follow command from the qtvcp panel, as well as the digital-out HAL pin to pulses with edge HAL components. The pulses go into or2 components. This way I have one "set" (track) command and one "reset" (park) command, but those are just pulses. I feed those signals into a flipflop component that is then actually controlling the shoe movement. See attached schematic. "ds" is my qtvcp panel, so ds.track and ds.park is the momentary panel buttons. text on the lines are the net names, text over the blocks are the component name. 

It's working, but I get into the situation that the motion.digital-out pin is not reflecting the status of the shoe if overriding it from the panel. It actually is a minor thing, as my M6 remap always park and then activating the shoe again. But I would like to have the motion pin reflecting actual state, just for sanity :)

Umbau der Steuerung auf LinuxCNC + EtherCAT

Hallo Pascal,

ich hatte zu dem Zeitpunkt noch nicht das Verständnis, wie das alles ineinander greift. Inzwischen bin ich soweit, dass ich die Motoren ansteuern kann.

Allerdings stolpere ich aktuell darüber, dass ich die Fräse (bzw. meinen Testaufbau) noch nicht in den "normalen" Zustand schalten kann. Ich habe ja einen Gantry Aufbau mit zwei Servos für die X-Achse. Allerdings kann ich in der Oberfläche bisher nur einzelne Motoren und keine Achsen auswählen.
Ich nehme an, dass das daran liegt, dass die Referenzierung noch nicht funktioniert.

Bevor ich mich allerdings um die Referenzierung kümmern kann, muss ich noch die Parametrierung machen, da die Servos aktuell zum Zittern neigen, sobald sie auch nur ein winziges Stück bewegt wurden.  Zwei Adapterkabel dazu habe ich inzwischen angefertigt, bin aber noch nicht dazu gekommen, die Parametrierung auch vorzunehmen.

Schönen Gruß,

Uwe

how to make M7 (mist on) generate step pulses

Category: G&M Codes

You can set do 'setp' command while linuxcnc is running via halcmd i think.
open a terminal and write halcmd -k (double check this syntax)

linuxcnc.org/docs/html/man/man1/halcmd.1.html

I think you can set set via bash commands, i haven't tried though
I think you make a file with your command and call it trough a custom Mcode.

in the file:
#!/bin/bash
# M101 - some command
halcmd setp parport.0.pin-XX-out true


There is some more steps to this. I think you need to ad a new new Mcode is the ini file RS274NGC section.

I hope this gives you enough to keywords to search.

M62-M65 (or likewise) from qtvcp panel during gcode execution

Category: Qtvcp

So m65 commands operate a dust cover and you want to override the controls manually while in auto mode?

You can control m65 directly while in auto mode other then with gcode.
But could you put some logic components between motion pins and the dust control pins that the control panel can control. Something like an OR component?

M62-M65 (or likewise) from qtvcp panel during gcode execution

Category: Qtvcp

A real noob on qtvcp I will say :)

From a qtvcp panel, is it possible to modify the motion.digital-out-xx HAL pins with M62-M65 during AUTO mode, as in when the machine is cutting, without going into MDI mode?

I would like this to have the ability to manually raise or park a Z independent dust shoe during cutting. The dust shoe is normally controlled with M62-65 during tool changes.

Thank you. I will look into this. I'll post what version of GUI I'm using when I can.

Almost certainly, provided it is capable of accepting either analog velocity or torque commands, or digital positioning commands (step/dir or quadrature.) or can do EtherCAT.

Calibration issue

Category: General LinuxCNC Questions

What size piece gives your 0.75" larger, or is the oversizing pretty consistently the same amount regardless of the size of the item or is it a proportional oversizing (bigger pieces off more smaller pieces off less?

Are you using tool diameter offsets? One possibility would be if you have your CAM program generating the tool path with tool offset, but are also using an additional tool offset in Linuxcnc.

How did you determine your step scaling? Did you calculate it from the drive mechanics, or did you use experimentation? (Measure a feed move and adjust the scale to get the size move you wanted.)

If you used experimentation and the system was loosing steps for some reason, This can give a fairly consistent offset in size variation for each move.
