Homing with 2 inputs/sensors?

Category: HAL

ahhhhaaaaa...

i think i got the firmware fixed on my table/labor mesa 7i92....

to explain:

I have everytime i configurate a new machine or want to try something a mesa 7i92 for learning on my table...
 

i load the firmware file for the 7i96 and look into it and found the example where index on a stepgen was attached.

Download:
link to the 7i96 firmware files

then extract and look for:
PIN_7I96_StepIDXD_51.vhd

then i saw in the file:

(StepGenTag, x"C2", ClockLowTag, x"04", StepGenRateAddr&PadT, StepGenNumRegs, x"00", StepGenMPBitMask),

bingo!

i add the stuff to my 7i92 bitfile...

Great feedback. Nothing to worry about. The etherlabmaster's certificate in their repository only has a life of 2 years. If you are not using ethercat, there is nothing to worry about. It is outside of our control.

Good morning,

I followed Rodw's instructions (thanks, Rodw), and upgraded from Bookworm to Trixie.
I can say that everything is fine. I only had two problems:

Several packages weren't installing automatically; they were always in the update list.
I installed them manually and solved the problem.

The Network Manager GUI in the top-right panel wouldn't start, and it was impossible to manage the network
with a graphical interface.
I solved the problem by searching online.

The thing that worries me is the warning that appears after I update from the terminal.


 


What does this warning mean?

Thanks

Category: HAL

Hi

If i understand correct... i must change the firmware on my 7i92?
I need to add encoder to the bitfile.. but only the index? So it must be a index that is coming from the stepgen.. i only know how to add stepgen with step and dir to the bitfile..


I run the stepgen in position mode ..not velocity..

So instead what i try with the gpio i need a index pin in the bitfile which is linked to the stepgen, right?

Sorry i am a little bit confused and doesnt understand it.. i use linuxcnc 2.9 and a mesa 7i92. Changing the bitfile/firmware is not a problem. But i look everytime to existing files and copy from them... and i cant find a documentation about it...

it should be look like:
IOPortTag & x"NN" & StepGenTag & StepGenIndexPin, "

but i never saw something like this...


thanks

I had noticed that just after I posted it, but I thought I tried uncommenting it and it I didn't think it seemed to make any difference. (Error messages were still the same and the Label didn't change.)

But I thought I had better test again before posting a reply. I loaded up a 2.7 Wheezy live cd image in a VM and ran a simulation with this GladeVCP files (and that line uncommented, and it works! I don't know maybe I forgot to save after uncommenting that line earlier today. But I'll have to wait until Monday to try it out on the real machine at work.

Thanks alot for your help.

PS any ideas on these other "error" messages that show up in the terminal but with no noticeable effect on functionality.

Sorry for the late reply, but i was waiting for someone else to reply as i am not sure if i can create a new section or not.
In the mean time, start a new topic here in Tyrkqe ? (is that correct) or rename this one and we will move or delete stuff around as needed.

You have commented out the line that defines self.stat:
class HandlerClass:
    def __init__(self, halcomp,builder,useropts):
        self.builder = builder
        self.halcomp = halcomp

if I try exporting the project as gcode the .ngc file is mostly composed of stuff that looks like this:

NativeCam has always output gcode in parametric form because it uses subroutines for it's operations (ie the output does not look like what you would expect on a regular 'CAM'). SO there may actually be nothing wrong with that output (except of course that it would need to be formatted properly)

I always impliment the following on my retrofits.

set up a spindle-at-speed signal in the usual way using encoder feedback and a near component.

invert it using a not component to set up a spindle-not-at-speed signal a d tie it to motion.feed-inhibit.

this will stop all motion when  the spindle is not near enough to the commanded speed.

Hello everyone,I managed to get Nativecam loaded and running on the 2.9.4 iso, using the github.com/freemoore/NativeCAM download, and Giovanni’s instruction pdf plus all the corrections along the way. I ran a huge victory lap when I saw the Nativecam Tab in Axis not blank but how it supposed to look! But…..as usual the fight is not over and my troubleshooting skills are limited by my total lack of experience with Nativcam as I have never used it before.The problem is the Nativecam project is not dynamically updating in the Axis preview ,tab and if I try exporting the project as gcode the .ngc file is mostly composed of stuff that looks like this:
(begin Workpiece)(workpiece definition author : Fernand Veilleux) #<wp_width> = [5.906000]#<wp_length> = [13.780000]#<wp_depth> = [0.125000]#<wp_wall> = [0.000000]#<wp_corner_radius> = [0.000000]#<wp_inside_width> = [#<wp_width> - #<wp_wall> * 2]#<wp_inside_length> = [#<wp_length> - #<wp_wall> * 2] #<wp_x> = -2.953000#<wp_y> = 0.000000 o<select> CALL [31] [0] [-2.953000] [-2.953000 - #<wp_length> / 2] [-2.953000 - #<wp_length>]#<wp_left> = #31#<wp_right> = [#<wp_left> + #<wp_length>]
I’ve been asking the AI questions about how Nativecam is supposed to work and I think its been mostly correct but is often describing how it “used to work” and not necessarily how it works now. My gut tells me the problem has something to do with a symbolic link or a missing ncam.ngc file. Any thoughts are greatly appreciated!-Doug

Category: Driver Boards

Hello satiowadahc,

I’m an applications engineer for Teknic and I came across your post. I’m sorry that you’re experiencing undesirable machine movement during a controller shutdown while the servo drive is still enabled. You've been working with my colleague here (and it sounds like you've also been implementing some other protective measures on the machine) - it's possible you've already fixed the issue, but I thought it might be helpful to post some additional relevant information in case anyone else experiences something similar and sees your post.

If a controller sends a static 5V signal, the drive would not respond (there isn’t any way for the drive to interpret a single high state as a command for motion). The Eclipse drives will only respond to step pulses (specifically, the falling edge of the change in state from a step pulse).

Digital devices rely on a voltage threshold to define high versus low signals. As a controller powers down, its output may decay and fluctuate around this threshold, creating multiple false transitions that the drive interprets as steps. The oscilloscope shots that you sent over to Teknic suggest that this is likely what's happening to the signal on the step line (as your controller powers down).

For safety, we recommend shutting down by first removing power (or disabling) the motion-generating device, then powering down the controller. Powering down the controller first introduces a fair amount of uncertainty because shutdown behavior varies across different controller manufacturers and configurations.

If you find that there is also noise on the signal, there are step input filters that can be programmed into your Eclipse Servo Drive to help with noise filtering, if you haven’t already configured that (there is more information on this in the Eclipse User Manual – pages 19-20).

I’d also recommend (if you haven’t already done so) grounding the Step and Direction lines according to the manufacturer's documentation. There are also instructions in the Eclipse User Manual that explain how to properly ground the signals to Eclipse.

I hope that this information is helpful. If you have any questions, please feel free to give Teknic a call (or contact the engineer that you’ve already been working with).

Best,
Andy O. – Teknic Servo Systems Engineer
