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

One thing you need to remember is that the PSU have an initial inrush current that is greater than the max current the PSU draws when running.
I went with fuses rather than circuit breakers.

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.

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.
