I apologise for the previous answer by the previous user, it really doesn't address your issue..
I'd go for this
www.hardkernel.com/shop/odroid-h4-plus/

I've been using the H3 Plus for a few years and had no issues with it. The only thing you need to do is use the non-kernel realtek drivers for the nic. I'm pretty sure Rod from the forum also uses one.

Waveshare also have this setup
www.waveshare.com/product/raspberry-pi/b...ule-box.htm?___SID=U

I'm currently running a mill with the C box but you're situation would be better suited to the A box.
I like the fact the case and connectors are well integrated, full size HDMI ports, all but the power switch, Serial console connector, and the connector to power it from a non-usb supply (meanwell would be a good choice) are on one side.
The only caveat is that the NIC is a realtek based one, but as long as the cnc stuff goes thru the RPi interface everything should be ok.

Langdons would please provide an answer relevant to the question, the user was looking for a small form factor PC, almost a similar size as a RPi5.

This is awesome! I actually just today started wiring up the retrofit of my EMCO Concept Mill 155. Newbie to linuxcnc, so it’s been going slow so far. Would you be open to sharing your setup files? I’ve got the same tool changer, would love to see your code for that.

I'm a bit concerned about the STEP/DIR wiring.

It appears that the thick white wires are grounding the STEP- and DIR- pins
This should never be done as it shorts out the STEP- and DIR- pins
possible damaging the driver chip.

If STEP- / DIR- are unused, they should be left unconnected.

Hello.

I Know that MPG mode is the default mode at startup for whb04b-6.  So When moving the handwheel  the FeedRate Override changes untill we press Cont or Step yellow button

Is there a way to start in Continuos o Step mode?????





 

VFD working

I try tomorow a lower speed . Thank you very much for a quick replay

What exactly do you need help with?

Are you sure it is not stalling because your accel/velocity values are too high?

if the distance moved with a 100 mm command is not inversely proportional
to the scale, the hardware is not following the  command.

500 mm/s is way faster than is possible.

Even at 300 steps per mm, 500 mm/s  needs a 150 KHz step rate, but your base thread
period limits you to only about 5KHz (5 KHz = about 16.6 mm/sec at 300 steps/mm)

I am trying to create a simple subroutine to surface a block before engraving. It originally complained about an EOF in the file so I decided to execute each move command individually using MDI to make sure the code was correct.

Here the snippet that is giving an error:

    G0 X2.144 Y-0.125   (Move to start)
    G0 Z-0.02           (Lower spindle)

    G91             (Relative Moves)
    G0 X-11.163     (Make cut)
    G90             (Absolute Moves)
    G0 Y1.6921      (Move Y for next cut)

    G91             (Relative Moves)
   -- -> G0 X11.163      (Make cut) <---
    G90             (Absolute Moves)
    G0 Y3.5092      (Move Y for next cut)
    G0 Z0.1         (Move to safe height)

At the line indicated --->  <--- LCNC reports an error to the effect that Linear Move will exceed limits of the machine.  The program zero is located at the right-front corner of the block. Since I could move to the starting location in line 1 and do the first cut to "G0 X-11.163" which is negative, I naively expected moving opposite direction the same distance would be acceptable.

The block, 3.25 x 7.00 in., is located in the center of the 19 x 11 in. table with ample space on all sides for the 2 in. surfacing mill to clear the block. Fortunately, this was my first attempt to use LCNC on this machine so I was cutting air for the test, so no material was damaged.

Can someone help explain the error and how to resolve it?

Kind Regards,

The GMOCCAPY documentation indicates that the arrow-keys, pg-up, pg-down are enabled by default, however, they are not responding on my installation from the main screen. I've looked for a configuration parameter to enable them, but the only key I found disables all hot keys, not just the jog keys. Am I doing something wrong or did I miss something in the documentation?

Hi I has problem with my setup  ini file  I do not understand the behavior of this if I use 200 step for the scale in my z axle and then G0Z-100 and the movment stop at 40 mm 
step 300 = 60 mm
step 400 =  81mm
step 500 = 78 mm
step 600 = 59 mm
Why can´'t I hit 100 mm in my set up I tryed many diferent value of steps with 50 increasment  
computer = Raspberry Pi 5 ,breakoutboard db25 cinese make , stepperdriver DM542  , 1/4 800 steps , motors 200 steps
are there any kind to help me in the right direction
yours sinserly Krister



   

I am looking for someone who would help me with my LinuxCnc project. We use laser welding to weld electric motor shaft before grinding. I am at the end but some small issues I can't resolve. If there is someone who can spare some time and help( I am willing to pay) would be much appriciated.

Boris

1. I only need 4 axes (X, Y1, Y2, Z). Can I use the last StepGen for torch on and laser pointer outputs?
2. I do not need encoders. Can I use the QCount pins as general-purpose inputs?
3. Can I use the pins labeled “None” or “unassigned” in the bitfile as inputs or outputs, depending on their pin direction?For example, pins 10 and 15 as inputs, and pin 14 as output?
4. Are pins 13 and 15 on P2 free to use as I/O?
5. My breakout board has 5 inputs labeled P10, P11, P12, P13, and P15. Can I use all of them as inputs

thanks again to everyone who helps!Best regards,
 

yes, I just needed to make sure

Info : By measuring I found that between the encoder inputs A-A/,B-B/,Z-Z/ there is a resistance of 120 Ohm, they are already integrated in the MESA card. So additional resistors are not needed. I did not find information about this in the manual
