REMAP M6 ERROR

Category: AXIS

Is there any more? This doesn't get as far as reporting the actual error.

I already found the problem. I had copied the remap.py, stdglue.py and stdglue.py files from the python folder that comes with probe_screen_v2.9 and these are the ones that were causing the error. I followed the instructions in the Remap extending chapter. G-Code and copied them from the usr/share/linuxcnc/ncfiles/remap-lib/python folder and that problem was solved. Now the problem that appeared is that when trying to load any tool these errors appear

 
They indicate a specific line but I don't know which file it corresponds to.

Can't get past "Configuring the Network" Screen on fresh install

Category: Installing LinuxCNC

Hello All,

I had earlier installed the Sherline EMC2 CD software onto this PC desktop... but that preconfigured system is based on the ancient Ubuntu 12.04 LTS and it cannot seem to find network drivers or PCI parallel port.  So am hoping to just install the latest Debian-based version of LinuxCNC from this website.

HOWEVER... Downloaded the latest LinuxCNC_2.9.2-amd64.hybrid.iso and put onto USB stick using Balena Etcher. Attempted multiple times to install onto Lenovo i3-8100 3.6GHz desktop.  Keeps hanging after I enter the information for either WiFi or LAN access... "Configuring the Network" on sceen... no progress beyond that.

Any suggestions about what I'm doing wrong?  Thank you.

Hello,
I have a problem on how to enable SPI on my PI4. I have used the   Raspberry Pi 4 OS based on Debian Bookworm  Image and now I am stuck. I already have installed mesa flash and try to see if can see my Mesacard with mesaflash but that only gives me the message: No 7C81 board found. 
Thanks in advance.

Yes. But apparently setting a 220v 1000hz motor to 135v and 600hz on this drive is not the same as just moving down the VF curve on a 1000hz drive. The engineer was confused as much as me. It should "just work" but it doesn't.

And of course as I found out, faster drives are not easy to get so I'm stuck with this compromise we found for now.

Hmm, I think the startup scrip does some magic but it freezes on me and does not print anything to the terminal.

AC induction motor voltage is speed dependent in the same way as DC motors.
They are more complex because of things like field weakening in the the armature,
but the basic behaviour is the same.

That is if you took a 240V 60 Hz AC induction motor and ran it at 1/2 speed at 30 Hz
you would need to reduce the voltage to approximately 120 V to avoid overcurrent/saturation

Ok went back to my Lattice dev board, and connected up via SPI, qt test works, LCNC does not. get header message error. Could be my wiring.

Once I finally worked out the pin changes in my sources, from about 12 months or so the UDP bridge works fine, well at least with qt test.
It's 1am, Marc crashed out of the Sprint at Assen (grumble grumble grumble), I'll attack it when the sun is up.

This is beginning to seem like an ID 10 T issue and it's all my fault.

One thing I noticed is Linuxcnc and RTAI versions don't match on the downloads page.
 

Dunno if that is an issue or not.

Means the SPI write to the FPGA took almost 4 ms.
As I mentioned before, this likely means that the
Orange PI's kernel SPI driver is not capable of
real time operation.
