Exchange Simodrive 610 to new components

Category: Computers and Hardware

I would first check the encoders, the thin slotted disk sometimes rusts and keeps getting worse with time.
You can check the Granite Devices, i did use Argon drives and they are quite versatile, but knowing how much time it takes, i would just go for the cheap china drives with motors.

By any chance do you mean 626VM3 ?
Is this it?

everybody wants to be a dev but i want to be a machinist

Category: Show Your Stuff

Nice plane, looks great made out of wood.
As for machinist, i am building a styrofoam cutter to make wings for RC planes, after building some 15 drones and a single 3D printed plane that has yet to fly.
I have built several styro cutters,eve a huge 5 axis one, but his one is for me. :)

NativeCAM Problems with Program Start after transfer to Control

Category: NativeCAM

What do you mean by "new program to the control" ?
Do you have 2 PC's running this and the one at the machine has issues, or what exactly?
Can you do a short video and upload to youtube or google drive?

Z axis torch initially going up instead of down when clicking cycle start

Category: Plasmac

If you want, you can post a backup of your config here, and I'll take a look at.

Your Z axis limit switch is at the top of travel right?

Looking urgently for a german / european Linux CNC consulting help.

Category: User Exchange

Moved to "user exchange".
-
I am in Europe and i can speak German, but i am of no use for probing, i still did not build a proper mill. I can figure out everything for sure, but the time it would take is probably much longer than someone with experience.
Also, i never charge for helping here or whatever is initiated from here.

Retrofitting a 3-axis VMC with DC servos - guidance needed

Category: Driver Boards

From what I've measured, the issue seems to be on the encoder side.

Shielded cable, shielding grounded on the Mesa side.

According to the diagrams, the analog signal for the axis is connected to the machine's frame/ground.

Analog cable has 2 wires plus shielding, shield must be grounded on the Mesa side, and one of those 2 wires is the analog ground.

Is it better to isolate the analog ground from the system ground? Under what conditions is it strictly necessary to tie both grounds together?

There is no exact reference for it, see above, use a DVM to measure between analog and machine ground both in AC and DC mode > if any of those read more than a Volt or two = do not connect. If that is all correct but still does not work, you can try grounding the analog ground to machine ground through a 1K resistor for a single line, test with only a single line/analog drive/connection to mesa.
-
As a general rule, use a very good power supply for the Mesa as the encoders are powered from it.

Debian 13.7 was only released earlier this month (on 12 September) so its quite possible at this early stage that something Debian did with versions that broke LinuxCNC. Instead of complaining to all and sundry, why not raise an issue on GitHub so the devs can look at it? They are probably not aware of the issue.

Z axis torch initially going up instead of down when clicking cycle start

Category: Plasmac

Ok so I got it fixed by finding some settings in my notes that worked. So basically I entered these settings to the Z axis.
 
Now the torch still goes up initially but it doesnt hit the limit and it cuts just fine.
 
Im not entirely sure how these changes fixed my machine.

NativeCAM Problems with Program Start after transfer to Control

Category: NativeCAM

Hello everyone,
I have installed the latest version of NativeCAM under the Gmoccapy user interface of LinuxCNC. So far it works, but every time after transferring a new program to the control, I always have to press the start button twice to launch the program.
The first time I press it, the milling spindle starts briefly, stops immediately, and then I receive several error messages:
  • invalid parameters in linear command
  • linear move on line 38 would exceed positive limit of axis/joint 2
  • linear move on line 38 would exceed positive limit of axis/joint Z
After that, I can restart the program again and again without any problems, until I transfer a new program (or the same one again) to the control.
What could be the cause of this error?
Thank you very much in advance for your help.

Connect external potmeters to rapid- and feedrate override sliders in QTDragon

Category: Qtvcp

Thanks again for setting me on the right track again, this is really appreciated. In my case I only included 2 potmeters on the console: one for rapid traverse override and one for feedrate override. I copied this from a DMU 50 console which we have at work...

Using HALshow and setting halui.rapid-override.direct-value to True (1) and then setting halui.rapid-override.counts to a manual value (I discovered that a value of 10 corresponds to 100%) works well together with QTDragon_HD. With that I mean that it will probably provide me with the functionality I need. I already wrote some HAL lines using the lincurve component to ensure that the output of the potmeters correspond to the tickmarks (it is not a linear scale...).  By setting up the right net statements I should be able to connect these and have QTDragon follow this setting on the display. Same for halui.feed-override.direct-value and ..counts.

@cmorley: Luckily I didn't include a jog override pot on my console, as I now understand from you that this would not work in a similar manner. I did already buy a pendant (XHC with cable type) and maybe I will run into issues once I try to get that connected. For now I first want to get the spindle and servo's running :-).

Thank you all for helping me further.

Sounds like numbpy is the wrong version.

More specifically, it looks like someone did some good work in the 2.9 branch (Qtdragon works with the new numpy 2.2.4), but didn't port it to the 2.10 branch...

As you said qtdragon being python doesn't compile anything.
It preprocess somethings into to bytecode.
Sounds like numbpy is the wrong version.
But now we can investigate, thank you.

So you didn't home the machine while trying to decide if the screen is 'useful' ?
and there was extra information in the list that you didn't like?
Oh and the colors -colors were bad.
And that was worth going on the forum and ranting about how bad the software is?
Sounds like you didn't give it much of a chance.

Shake my head.

I'll try to replicate the numbpy problem.
