Hi PCW.
The dip's on the drivers have it as needing 1600 (or 25600) pulses for 1 revolution.
In the stepper settings in Lightburn you set the pulses per revolution, so 25600. And I was expecting the same behaviour in LinuxCNC.
You are saying that in LinuxCNC you have to tell it how many microsteps are in 1 regular step? But how do i know how many full steps there are in 1 revolution?
So to what number would I have to change the 1000 then? And what about the step times?

Thank you Rob. I have found the following specs on the MDR-100-24 PSU:

I don't think the 1600 and 25600 numbers are microsteps, but rather
steps per turn, so 1600 = 8 microsteps and 25600 = 128 microsteps

After you install Flex GUI from the CNC menu select Copy Flex Examples and all of the current examples will be in the linuxcnc/configs/flex_examples directory. Also after you install Flex GUI the PDF doc is on the CNC menu as well as some tools.

I don't care a whole lot for watching videos but sometimes it gets the idea across better when you can see someone click on this then do that in a video. I really hate videos with zoom bang intros or looking at some ugly mug in the corner of the video.

Hallo miteinander,
ich habe das Debian hier von der Seite bei mir installiert, seit einiger Zeit stimmt meine Uhr nicht mehr vom System.
Wie kann ich das beheben?

Ich nutze Debian 12

Es ist jetzt =>  16:50 Uhr
Das System sagt: 17:12 Uhr

Was ist da nicht richtig Synchronisiert

 

Gruß Mücke

 

if you found a ui file that you like

Ah -- but that other question:   where would I find complete UIs?

I may watch a few videos, but I'm a little old skool when it comes to TV time on the computer. Once I find my way around the docs, I think I'll be fine. Thanks for the INI file pointer.

There are quite a few running Flex GUI on machines.

JT

Yes, if you found a ui file that you like you can just copy that to your new configuration directory and change the DISPLAY and add the GUI setting.

There are quite a few running Flex GUI on their machines including myself. It is quite stable now.

I have a lot of videos on getting up and running with Flex GUI
First tutorial videos

Now that Flex GUI is on version 1.2.0 I plan on making new videos to show off the features and how to add and use them.

You would normally use ENCB for direction.
(and set counter-mode to true for "Step/Dir")

From the hostmot2 manual page:

       counter-mode (bit r/w)
           Set to False (the default) for Quadrature. Set to True for Step/Dir (in which case
           Step is on the A pin and Dir is on the B pin).

Using GPIO for direction could lose/gain counts on
a direction change.

Note that if you need more encoder channels, there are 7I96S configurations with multiple
encoders on the P1 expansion connector.

Hello Hivemind.
As the title suggests I'm having issues setting up my drives.
I have a 4 axis setup. All the same drivers (Leadshine HBS86H) and steppers (closed loop).
The only motor I get to run during the setup stage is the A-axis. And I'm sure that the turn rate is incorrect.
Main problem is that there is no preset available for the HBS86H driver. And no matter how low I set the Step on-time and step space, when I go to ' calculate scale' I can't get the pulses per revolution above 1000.
The driver microsteps are: X&A=1600, Y&Z=25600.

Does anyone have any tips on this?

PS I had this setup working years ago. It's been collecting dust since 2017. And I fairly blindly just upgraded the LinuxCNC OS/SW. Not sure if I have my old configs somewhere.

Anyone just try using dxf2gcode?

I just got a little laser going and was a bit surprised there weren't more options. Nothing against paid software but it's alot easier to just try something out if it's open source.

I tried gcodetools for Inkscape, but I couldn't figure it out....probably just not patient enough. I went back and forth with dxf2gcode a couple of times and seems like I got it figured out. For some strange reason it doesn't have a plasma/laser configuration option, it's meant for mills I guess but I've never had the urge to use a DXF on my CNC mill so not sure it's really targeting the right group.

Anyway after some configuration that isn't quite obvious it seems I have it working pretty well. It does cutter comp but I don't bother since a diode laser kerf is pretty small.

Been reading about Flexible this morning -- this looks like a good project!

Couple of questions, though.

I assume that if one found a UI that was close, it would be easy to modify, right? There's no reason for everyone to start from scratch?

Is there a gallery of sample UI screenshots? For that matter, is there a repository of completed interfaces from users?  (I realize this is a relatively new project, so I may be overestimating the user base.    I've been using Axis for 20 years, but other than adding my own pyvcp panel for probing and a few other things, my needs are very simple.  Probably similar to the UI shown by @109jb four (or so) posts back.

The .ini and .hal files for my DIY mill (3 axis, very simple) were (re)generated by pncconf. To try Flex, I guess I'd create a new mill directory, copy my conf files, and edit the DISPLAY section to point to Flex? Just trying to get a handle on the "getting started" part.

Finally:  how stable is the project?  @JT -- are you running it yourself, all the time?  (I think that's necessary but not sufficient as a gauge of stability --  sers always find bugs that developers don't, of course.)

I forgot to say thanks to bkt for testing that out, it's good to know that that stuff at least somewhat works.

I got busy with other things and set my DIY  PnP machine off to the side for a while but I just recently resurrected it as a laser cutter that can be swapped back to a PnP once I make a universal head for it.

Not sure how long it will be until I get back to the PnP thing but I really wish there was more activity with the PnP stuff in LinuxCNC. Since I don't actually own a PnP I never actually used one so it'll be a bit daunting if I have to pick this up from scratch.

Kind of surprising there isn't more activity with PnPs in LinuxCNC, it can already do almost everything it would need to without all the weird pseudo Gcode nonsense that OpenPnP uses. With all the cheap PCB manufacturers these days, you'd think we'd all be building PnPs.
