Category: General LinuxCNC Questions

I have a feeling the way I'm trying to wire my end and home min stops is the prob(use to 3d printers) but I redid the pnconfig using discover board and now the endstops don't stop me from turning the machin on in linuxcnc so I'm slowly getting there

No, just the statistics reported at the end of:

ping -c 4 -i .2 10.10.10.10
sudo chrt 99 ping -i .001 -q -c  60000 10.10.10.10

The last command will run for 1 minute

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

Hello,

I'm trying to set up an EC500 board with Remora firmware, but I'm encountering an issue.
I successfully flashed the latest BIN file to the MCU (using DAPLink, PyOCD, etc.).
Then, I tried to upload the DMA-based stepgen configuration (
ec500-rt1052-DMA.txt
), but Remora reports:
JSON Config file CRC incorrect
My Python version is 3.11.2

Here is the upload log:
Valid JSON config file, uploading to NVEM board
Config file length (words) = 2171
Config file length (bytes) = 8681
Remainder = 1
Padding added =  [0, 0, 0]
Config file length with padding (bytes) = 8684
CRC-32 = 0x28a8b96b

And this is the serial port response:
Receiving new configuration. Stopping threads..
    timer stop
    timer stop


Checking new configuration file
mod = 1, padding = 3
Length (words) = 2171
JSON length (bytes) = 8681
crc32 = c17ec40f
JSON Config file CRC incorrect
Has anyone encountered this issue before?
What am I doing wrong?Thanks in advance!

Typically you just have one track of holes and the B detector offset from the A detector by
hole_pitch*(N+1/4). That is, if the holes were 2 mm apart, the A/B detectors would be
spaced .50 MM or 2.50 mm or 4.50 mm etc.

This 1/4 pitch offset gives you the desired 90 degree phase difference between A and B.
Note the when drilling holes you should aim for a 50% duty cycle waveform
on A and B. This may require some experimentation and changing  the sensors
radial positions.
