I created two configurations for 7i96s. One on the carousel component, the other on the ladder. The ladder works fine with Remap T and Ignore m6, just like when changing tools manually. When working with the carousel component, Remap T throws an error "M6: no tool prepared". Remap M6 = Ignore M6 - does not work at all, since Remap M6 is already used. In the configuration, these functions are disabled in the ini file.

Hello @cornholio,

You are right - I need to move on to LinuxCNC. I noticed a new CNC machine. It's called "Maslow". Google it as "Maslow CNC".

I want to use it for cutting out frame members for wooden boats.

Does LinuxCNC support it or does something need to be done?

From reading their blurb it seems to use a GRBL type controller, not compatible with Linuxcnc's model. Just for future reference anything that connects via USB (as of this current time) or uses a GRBL type controller is not compatible with Linuxcnc.

I always thought kinematics related to the motion of a machine, very math intensive, I wasn't aware speed would negate it.

I have concerns with the machine, the main one being what stops the cutter platform from raising if it hits a knot or other harder section of plywood. I really didn't read too much about it. It may be a reasonable design but not something I'd spend any money on.

A Lowrider would be another option. docs.v1e.com/lowrider/
Tho with the amount of plastic involved meh.

Thanks, much appreciated!
Yeah, the board was a pretty attractive option when I bought about 6 years ago.

Automationdirect (dot com) ships to Canada. Excellent selection of drives, etc. and other supplies.

was the only useful one for me. This is the bash scrip that I wrote to produce a hole centered in a box specified by four points. There are two files that this script uses.

#!/bin/bash

# Cut an interior circle starting at xStartBB yStartBB xEndBB yEndBB zStart zStep zEnd feedRate holeDiameter endMillDiameter

# BB is short for BoundingBox

if [ "$#" -eq 0 ];

then echo "$0 xBB yBB xEndBB yEndBB zStart stepZ endZ feedRate holeDiameter endMillDiameter"

else

xStartBB=$1

yStartBB=$2

xEndBB=$3

yEndBB=$4

startZ=$5

stepZ=$6

endZ=$7

feedRate=$8

holeDiameter=$9

endMillDiameter=${10}

millRadius=`echo "$endMillDiameter/2"|bc -l`

# Calculate starting cut points

echo $xEndBB $xStartBB $holeDiameter

center=`echo "(($xEndBB-$xStartBB)/2)"|bc -l`

offset=`echo "((($xEndBB-$xStartBB)-($holeDiameter))/2)"|bc -l`

startXCut=`echo "$xStartBB+$offset+$millRadius"|bc -l`

startYCut=`echo "($yEndBB-$yStartBB)/2"|bc -l`

endYCut=$startYCut

endXCut=`echo "$yEndBB - $offset - $millRadius"|bc -l`

# calculate radius for i

i=`echo "($center-$startXCut)"|bc -l`

cat prolog.nc >rotate.nc

echo "g1 z1.0 f$feedRate" >>rotate.nc

echo "g1 x$startXCut y$startYCut f$feedRate" >>rotate.nc

echo "g1 z$startZ y$startYCut f$feedRate" >>rotate.nc

newstartZ=`echo "$startZ+$stepZ"|bc -l`

for curZ in `seq $newstartZ $stepZ $endZ`

do

echo "g1 z$curZ f$feedRate" >>rotate.nc

echo "g2 x$endXCut y$endYCut i$i j0 f$feedRate" >>rotate.nc

echo "x$startXCut y$startYCut j0 i-$i" >>rotate.nc

done

echo "g1 z1.0 f$feedRate" >>rotate.nc

cat epilog.nc >>rotate.nc

fi

The two external files are prolog.nc

g17 g20 g54

and epilog.nc

just use the one here github.com/scottalford75/Remora-NVEM/tree/main/Firmware
use only the files in that repo for linuxcnc installation as well, the remora-nv one
everything in the videos about this stm board will still be relevant im sure


these stm ethernet boards have more users than i would have guessed

Hi, I am new to LinuxCNC and have some questions about how LinuxCNC find the RT CPU (isolate CPU core) on PREEMPT_RT.
It seems the find_rt_cpu_number() function in uspace_rtapi_app.cc either choose the environment variable RTAPI_CPU_NUMBER (which is NULL if not set manually) or choose the last CPU core regardless of whether there is an isolated core.
e.g. The isolate core on my Preempt_RT is core 1, but find_rt_cpu_number() returns 3 and the RT thread is running on core3 in the attached images.

My test version is LINUXCNC - 2.10.0~pre0. Thx for your time :-D

 

Thank you. I noticed that a few minutes ago.

There are some variables to enable hole mode etc in the top of the plasmac post processor in sheetcam. They may help

Is there another way to upgrade to version 2.10?

This is a bit tricky if you are using the 2.9 download. the official Linuxcnc repo does not contain 2.10
You would need to edit linuxcnc-uspace.list in one of the /etc/apt folders to use the buildbot2 settings described here
buildbot2.highlab.com/

Otherwise download a deb file from there and install it.
 

Assuming you are using the linuxcnc rpi 4 image, on the command line, try typing menu-config and selecting the correct locale for your part of the world

First attempt at physically fitting everything together.


Need to work on the 24V and 5V power supply mounting.

I really didn't like the last one so I tried something different and this is the result.
You don't need user_live_update, just use the below in bigfileopen.tcl. 

I believe so. 

is it for sure an STM32 board?
