Flex GUI Keyboard Jogging

Category: Flex GUI

This is works cool
And is there option for toggle between continues and limited (0.01 0.1 1) movements? I mean for example if keyboard jog is active, and i push 1 on keyboard, jog speed switch to 0.01, if i push 2 on the keyboard, then jog speed switch to 0.1 etc

THC not getting active even when "all seemingly needed" requirements are met

Category: Plasmac

ok, found this to try those 2 seconds maybe:

Two methods of THC activation are available and are selected with the Auto Activation check-button. Both methods begin their calculations when the current velocity of the torch matches the cut feed rate specified for the selected material:

Delay Activation (the default) is selected when Auto Activation is unchecked. This method uses a time delay set with the Delay parameter.

Auto Activation is selected when Auto Activation is checked. This method determines that the arc voltage is stable by using the Sample Counts and Sample Threshold parameters.

I am trying to generate a pop up window telling if the nozzle needs change depending on the distance traveled.

Pico Systems Servo Controller

Category: User Exchange

Had these sitting around and figured someone might be able to put them to use.  Pico Systems servo controller with 2 servo amps and braking resistor modules.  Also includes a spindle dac.  Had this running a 2 axis lathe that I ended up having to scrap.  $150 shipped in the US.

Leave enabled pin active when leaving linuxcnc

Category: Basic Configuration

And that's why it keeps turning off the 220v going to the vfd when I close linuxcnc to pickup the new settings I'm working on in the HAL and ini. For me it's a lot of brute-force and ignorance working in there sometimes and trial & error to get things working. (And a whole lot of help from you guys, thank goodness)

I'll hot-wire the SSR to keep the vfd from having to reboot every few minutes until I get this somewhat sorted out. I think I've at least figured out what's causing my gear function, that'll be the next series of questions lol
Thanks again

Servo tuning

Category: General LinuxCNC Questions

Servo Tuning advice needed!

Attached are the oscilloscope reading from our 4 axis mill, we are using mesaboards to retrofit a bostomatic machine. Any tips on tuning the servo parameters would be great.  The readings are all from the X axis we had it doing 2 inch movements at the same velocity. If anyone has pointers on PID values based on the readings that would be so helpful.  Also all the other values are 0 unless otherwise written in the slide.

Probe in Sim works okay... now comparing the various files.
Thanks for the suggestion.

Lathe C axis homing

Category: General LinuxCNC Questions

Forgot some important safety stuff...

M254 also sets an M5, as well as turns on spindle.N.inhibit.

M255 also sets an M5, and turns off spindle.N.inhibit.

I got caught out by this during testing when I left an M3 command active and switched to C-axis.  When I switched back to spindle mode and gave it an Sxxxx RPM value it immediately started rotating.  That was a pants-fudge event...

As you go through my HAL file, you may notice some partly-related but (perhaps) unclear functions/logic.  One of these is a spindle disable/freewheel feature which I use when indicating a part or toolholder.

My particular spindle motor (SZGH) does not permit freewheeling the motor in velocity mode if it's enabled.  Simply disconnecting the drive enable whenever you want isn't good enough, because the C-axis freaks out with a following error once you start rotating the chuck by hand.  So the disable function has a bunch of checks to make sure C-axis is paused, and there are no other backstage things trying to force the motor to spin the moment you turn the freewheel function off.

Lathe C axis homing

Category: General LinuxCNC Questions

Calling m419/420 causes errors with "ngc file ended with no % sign or program end" and unknown m119/120 code.

Note that mcode files containing executable code (eg m119, m120) need to marked as executable (right click on the file -> properties -> permissions).

No, the machine starts up in C-axis mode.  Actually, it may be more useful to think of it as the C-axis is always 'on', but paused when the spindle or orient is engaged.
  • Start LCNC
    • C-axis is not paused, encoder disconnect not active
  • Home all axes
    • axes-are-homed triggers C-axis homing
  • C-axis is-homed signal triggers M255 via one-shot and halui.mdi
  • M255
    • Checks if C-axis is homed, abort if not homed
    • G0 C0
    • Disconnect encoder from c-axis joint/axis and PID
    • Disable C-axis PID
    • Change stepgen settings to spindle values
  • Now in spindle mode, all automatically.
To get back in C-axis mode:
  • M254
    • Checks if C-axis is homed, abort if not homed
    • M19 orient spindle to 0 position
    • change stepgen to C-axis values
    • reconnect encoder
    • enable PID
  • C-axis is on, and positioned at C0

Minor tip: one thing that frequently trips me up when copying/using other people's files is forgetting to change the M-code (and other) path(s) in the INI file.

Issue getting XYYZ gantry to home (using 7i92t with 7i76u)

Category: Basic Configuration

You have HOME and HOME_OFFSET values mixed up, HOME = 0 , HOME_OFFSET = -4 or whatever value suits your machine.
Also, it seems you have one of the Y joints reversed, so be careful when jogging it, slowly, to check if all is OK.
