What do you really get for a $350 desk top engraver ?

Category: Show Your Stuff

It is possible to build a belt driven reduction that mounts in place of a NEMA23 motor. I did it here (but using a pinion.)

the biggest problem is the machine is built already and space is limited. if i could do any kind of reduction it would probably have to hang out to the side but if i could come up with a way now i know i can put whatever size on the open loop side and increase the circumference to get more engagement. i think the belt is compressing under load with a tiny 24 tooth pulley. so if it is doing it on the open loop belt side a bigger set on the other side would be a good idea too i think if it's even possible my fear is i painted myself into a corner :)

i will have to dig some more and look at the stuff you suggested in more depth thanks for the feedback :)

straight cuts work just fine but cutting a contour is where things get weird shows up looking like chatter when trying to finish. it is so close to being there but needs a little help to get that little extra bit of stiffness needed :)

Notes from installation of ethercat on Raspberry Pi 4

Category: EtherCAT

are you using this image ? www.linuxcnc.org/iso/rpi-4-debian-bookwo...23-11-17-1731.img.xz . are you using this(www.raspberrypi.com/software/) application for preparing your sd-card..? RAM size of your rpi above 4GB means good.

Also note that this seems to be used in the GUI:

./src/probe_basic/probe_basic.ui:7592: <string>M61 Q0 G49 #5210 = 0 #3991 = 0</string>
./src/probe_basic/probe_basic.ui:9605: <string>M61 Q0 G49 #5210 = 0 #3991 = 0</string>

Probe Basic subroutine parameter - #5210?

Category: QtPyVCP

I'm not familiar with PB but this does seem a problematic way of doing things.
One problem with writing #5210 directly like that is that the python status channel gets out of sync with the actual state because this does not set the values of the 'g92_offset' attribute (which is supposed to reflect the currently active g92/g52 offset values) to zero.
While this may not a problem for the GUI it might well upset a custom python component.

Might be worth looking at dmesg just after starting linuxcnc
So linuxcnc aborts running the config ?

Does linuxcnc report anything ?

What voltage are your motors running?
What stepper drivers are you using?
It might be as simple as upgrading to a 48 volt power supply if your drivers can handle it

Linuxcnc start disables Parallel port of PCI Express card

Category: Basic Configuration

Hi Forum,

I am chasing a weird issue. I recently got a new old PC with great latency for software stepping. I have a running set up with 2 parallel port cards one of them a pci express card.

I installed a clean version of LinuxCNC, copied the config files and added the new address of the parallel port card. The card is recognized from linux as active.

As soon as I start LinuxCNC the card is switched to disabled. I tried to change the /sys/bus/..../enable file. The file still has a 1 even if the port shows with lspci -vv disabled. I can't change the file at all, even as root I am not able to change the file it says file is locked. chmod 777 on this file did not help either.

I don't know why that happens. Due to a dual boot set up I have on this PC I had to install linuxcnc a few times until I had the move cleaned. Meanwhile I had it working when I used UEFI instead of leagcy bios. But with UEFI Linux sometimes the pci express card wasn't seen at all and only showed up when I unpluged the power cord of the PC.

This is so frustrating.

If I just simply clone the old linuxcnc 2.9.3 with a 4.xx Kernel all works. But the fresh installed linuxcnc does not work.

Hi,
I was wondering if anyone could help me. I need to replace the stepper motor on the z-axis. It is a small nema 23 . I want to replace it with some motors with more torque. Is it possible to use a hybrid motor only on the z-axis? I am using a CS-Labs CSM10/IP-M motion controller and Mach3. Thanks[/url]
