The OHMIC TEST button does not move the Z axis.  The intent is to see if there is a short between the torch tip and the ohmic lead (a ball of oxide can do this, or water from a water table).

User Manual Explanation of OHMIC TEST

If you do have a short, or you create a short to test it, you also need to hold the button to get the OHMIC light to light up in the GUI as there is sometimes a delay.  The click you are doing is far too fast.  

Ok I tried fixing it again

Hey that is awesome how you customized the Axis interface like that. Is there a way I can get a copy of that to use on my machine? I really need a search feature in Axis for the GCode so I'm able to goto a specific line and rerun the cut. Like so Im able to search for M6 T1 or M6 T3, T4, T5, etc.... and then re-run the code from that line after changing the tool diameter and making fine tuning of the parts using cutter compensation and or fine tuning the coordinate shifts. Anyways cool! I need this too

It was dist-upgrade being the issue, upgrade is fine as the kernel is pinned anyways.

As usual your comments add nothing to the discussion.

Hello scotta,

thank you for your quick reply. Yes, that is exactly what I thought myself.

The EC500 is powered by an external power supply. From the 6 pin header, GND, SCK and SDO have been connected to one of the probes.

I don´t have any kind of schematic on hands for the EC500. So I am not shure, why the header pin is labeled SDO. I would expect SDIO for a sufficient SWD connector. Is your header labeled with a SDO too?

My EC500 is labeled with IMXR_EC500 2023-05-18

Up to now, there has not been a single successful flash. From within MCUExpresso, I am at least able to build your application.

If this is not going to be successful: do you think, your actual project with W5500 and raspberry pi pico is as powerful as the 1052 solution and could be a viable alternative?

Thank you very much. I will try to give more details tomorrow.

Cheers Julius

 

Hi Scotta, do you happen to know what the error I'm having means? It seems like it's not communicating with the cloud in any way.

Hi Julius,

Very strange that one of those combinations don't work, especially MCUExpressoIDE.

For flashing
1. board is externally powered from 24v, so no VCC connection
2. GND, SCK and SWDIO is all the connections needed to the CMSIS-DAP probe

When I've experienced connection issues, powering on the board as the probe is trying to connect to the MCU has helped.

Your answer is a technical explanation of why this is the case. However, I look at it from a user perspective. I take it that there is unnecessary information in manual and MDI mode. I understand that removing this is extra work, but it is not unsolvable.

Is there any reason why "G-code properties" is also displayed in manual and mdi mode?

It is there in manual mode as well, because it is part of a box that is displayed in all modes, so this is also displayed in all modes.

At long last, here it is:

Hello dear EC500 users,

same as Thayloreing , I had a quite frustrating time trying to flash my EC500 over the last months. And there still is no success. So I am considering quitting the whole thing but I want to give it a last try by registering to this forum.

The problem is to get the firmware into the flash... and I did not find any solution that is working for me. I even can not reproduce the video from scotta with the reprogrammed STLink/V2 stick.

I tried:

• Modified STLink/V2
• DAP Link probe from Aliexpress
• JLink Edu mini

on

• pyOCD
• MCUExpressoIDE
• On Windows and Linux

I was not able to use the modified ST-link/V2 stick (as in the video from scotta) as a mass storage device under Windows for drag and drop usage. It simply does not show up in Explorer. I checked this with 3 different computers.

The DAP Link Probe is being detected under Linux and is attached to /dev/ttyACMx, but flashing with pyOCD leads only to the prompt: no ACK.

Using both probes under MCUExpressoIDE under Linux is useless, because they are not detected at all. JLink shows up, can be selected but stops programming by stating: can't stop CPU.

The EC500 seems to be a quite nice piece of hardware and I would like to use it in my projects.

Is there a working solution to flash this board available anywhere? I was not able to find any reliable solution what so ever.
Further on: Is the programming interface on the EC500 even usable? And what pins has to be used? There are:

• VCC
• GND
• SCK
• SWO
• Boot_MO
• Pro_B

Is this a sufficient pinout for a  working interface for SWD? SWO is for CPU output, not for data input. And what are Boot_MO and Pro_B good for?

I hope for any help on that topic. Programming a MCU should not be that complicated...

Cheers Julius

Hi, I have finished the lathe with ethercat drivers. I'm posting my configuration. I am using a revolver head with asynchronous motor with carousel control. mesa reads the encoder and buttons. the machine is cast in steel.

I am currently working on a machine with two X axes 1500x3000mm, what should I do so that with the incremental encoder it can align the bridge if it moves a little in reset mode.
