What is the deadband set to in pid?
Try changing that.

@Tiagounderground,

Is this available for test? I have a high speed glass cutting machine that would greatly improve his performance with this features

Yes, you can test or run the application in posix realtime or non-realtime.
However it is still not finished in the sence of look ahead features and more.
You can test it carefully on your machine on your own risk off course.
It has no homing features, but you can look at the hal file how to setup the axis for a xxyz machine.

Best to build the app is using the ./recompile script.
But first build& install this opencascade and clothoids

Here is the script to actually run a parport machine, this is tested ok.

 

these is my mechanical execution on vertical axis .... Delta A2 have smooth vibration parameter .....it works, and with my surprize, using ethercat, a little bit hight min ferror I can use "S" curve regulations without issue for Lcnc. These is ok!! Min ferror must be 20 in my case ... and set it 40 ...... so can use "S" curve parameter in asda soft and servo.

I try to leave it out and set Lcnc min ferror correctly to 20 ..... but impossible leave out the problem.

I have a problem ... my T10 belt is long ... so a little bit elasticity they have .... so when from slow velocity command a quite hight acceleration and velocity sometime servo goes on vibration state ... means it vibrate but run (motor sounds become from "zzzzzzzzzz" to "rrrrrrrrrrr" ).... seems it try continuosly to correct the position ..... I play with I and P parameter whitout success ... or little succes (in Lcnc and asda soft too), plus I play with smooth vibration parameter in asda soft ... actually result servo goes in these stranges state 95% less of time .... but not able to leave out these problem .... how can leave out?

Min ferror is 40 and Ferror is 120 .... so 3 time .... these can not be the problem I think ..... If increase P motor have strange sound ... if decrease too mutch not respect the position or accelerate too smooth .... co I and P param seems correctly set. Plus these parameters is equal as asdasoft find with asda app for motor parameter calibration ....

So any ideas on?

thanks a lot
regards

Some unsolicited advice...

If you plan to make an enclosure for the screen, make sure to either:

• Buy an extra screen in case the first one breaks and has been obsoleted by the mfgr, or
• Build a separate bezel that's fairly wide and mount the monitor to that.  The bezel then gets mounted to the enclosure.
  • If you have to replace the monitor with something else, you only have to make a new bezel to fit the new screen dimensions.

No worries, I am all for unsolicited, good advice and yours make good sense. Thanks:)
To begin with, I'll keep it simple screen on a Vesa arm and keyboard under it, I think. But I wouldn't be surprised if I want to enclose it later on.

Had this stuff for couple years but everytime I try and get something setup I run into problems and then just put it back in a box and back on a shelf.

But now I have an actual need to get this going to replace a 10yr old CandCNC packaged system.

Tried flashing the 7i96s_dpl firmware.

Returns the error: Invalid bitfile header!

The couple other posts I found mentioned updating mesaflash. My current mesaflash version is 3.4.9, and I’m not savy enough with reading github to know if thats up to date or not.

Not to mention network manager seems to be missing on the pi image, or at least there is no straightforward way of launching the gui for it from any menu I’ve looked in. So currently no internet connection on the pi, will work on that tomorrow.

hello,

I do not know, but I did my custom component and overwrite the gearchange.comp as my choise because of my lathe setup... I need a little bit more stuff to control

I think a default gearchange.comp from andy will be helpfull for you, because it solve all the stuff but no CSS .. I need them for my setup therefore I did customization...

sorry for late ... need to read from these point ... forum.linuxcnc.org/9-installing-linuxcnc...n-edition-6?start=20 ..... not remember where but at some point I have the same issue ... but if read post from that point fo sure you find my solutions .... seems need to install some dependancy .... find it using debian package command

For anyone it might help: QtDragon has documentation for setting up a toolsetter and an M6 remap that will use that toolsetter to automate the measuring of the new tool length after a tool change.

The stock code as of this comment isn't usable since it doesn't return the machine to the same location as before the tool-change was called.

There's a pull request that hopes to address that: PR 2706 .

There's also a post of that code at my stand-alone repository .

And there's a video of how it can be setup and used over on youtube .

It's also attached here, substitute it in your QtDragon configuration wherever you find qt_auto_probe_tool.ngc.

All the best.

Just for kicks, ask your post office how much would it cost to send such a thing here, but be warned: having a glass of water on hand is highly advisable, and so are sedatives!

On the brighter side, since this year we are able to travel again visa free in EU, after over 25 years!
 

I am from Slovakia that should not be problem to send a parcel.. but problem should be the encoder type and motor parameters.. please take a picture of motor nameplate .. if it will support a feedback type and continuos current..

hello

have anybody idea what is going on here?

I did some core frequency setup to hard value and ethercatMaster stopped working...

bro, that's a good idea.

this is great stuff, though I don't see any difference for state_led from the master branch version.

What is the difference between gearchange and gearchoise hal components?
My mill has 2 gear positions(low-high) enabled by solenoid valve and 2 sensors for 2 positions which hal component must use?

A 7I96S would do as it has the 0-10V VFD output  and 5 step/dir axis
and support MPG encoders. You might run out of inputs however.

What signal levels are the Z (Index) outputs?

Another possibility is a 7I95T but its likely overkill

 

Hi again, 
So, I attached some screenshots from the Delta servo manual a few posts above but don't know if they answer your question about the Z pulse signal levels.

Also, I tried to do an updated IO list below. Kinda worst case scenario for now, though. But given the list, which daughter card would you recommend?

Out

• 4 axis, step/dir
• 1 spindle via VFD 
  For mist coolant (fancy setup with a peristaltic pump):
• 1 enable for the peristaltic pump (stepper with its own driver board with a range of speed settings)
• 1 solenoid for air (I could run them on the same pin, I guess but it would be nice to also have the option of only running air) 

In

• 1 4-axis MPG with axis select and increment knobs
• 1 tool setter 
• 1 probe 
• 6 limit switches.I don’t know if these should be connected in series and what the impact would be, except for saving on pins. But I could also feed limit switches to the servo drivers and not the Mesa. 
• 1 “home switch” for rotary homing together with Z pulse 
• 4  Z pulse from the servo drives for homing (rotary axis at some point in the future) 
• 3-4 Servo Enables (I can also program the servos to enable by default as the drives power on) 
• 3-4 Servo Alarms (not sure it’s needed) 
• 3-4 Servo Alarm Resets (not sure it’s needed) 
• 3-4 Servo COMs (not sure it’s needed) 
• 3-4 E-stop to servo drives (Not really needed but may be nice to have the drives stop the servos?)

Again, this is my first CNC, so I am not sure what’s prudent nor practical. Maybe it’s ok to run all limit switches in series and maybe the servo enables, alarms and resets, too? Also, no hard buttons at all on that list and I may have forgotten something. But it sure starts looking like some more IOs would be nice.
