qtvismach, a axis toolpath

Category: Qtvcp

There is one problem after the last changes.

The tool trace disappears after 30 minutes.

It looks like the tool trace is constantly being saved, even though the machine and simulation are not making any movement. I think it is constantly saving to some buffer which, when filled, deletes the oldest content.

The screen in vismach is refreshed every 100ms, if I decrease this value, the trace will disappear earlier than 30 minutes.

need help！ mesa 7i95 connection problem

Category: Driver Boards

Hello,

sudo lspci -nn|grep -i ethernet delivers:

"Ethernet controller [0200]: Intel Corporation Ethernet Controller I225-V [8086:15f3] {rev 03}"

further trials did not result in much other than: again 1:45 am :-)

I tried another mini PC that I bought really cheap. Some difficulties to install from USB stick. I am not sure why it refused to install "uefi files" at first. (yet again I "fixed it" by random clicks on different options). The Ethernet adapter on this cheap Mini (it worked yesterday with the now deleted Windows 11) is a Motorcomm YT6801. This Ethernet adapter was not detected during installation. I tried to get it running using this instruction.
github.com/dante1613/Motorcomm-YT6801/bl...20-%20instruction.md
I have the feeling, that I messed the installation up quite a bit, not knowing what I am doing... :-)

.
The Motorcomm adaper showed (initial value for rx-usecs: 200), smallest value I could set with the ethtool (trying), was rx-usecs:3. The ping times seem to be influenced by that and went down from approx. below 0.5 ms to below 0.2 ms

Latency test in general I did not do these days.

Thank you for helping, so I am relieved that the 7i95 is still working.

THC with Beckhoff EL5101 and THCAD2 => encoder signal loss

Category: Plasmac

Hello everybody,

Thank you all very much for your inputs and recommendations. I can test most of them next weekend and report back to you.

I've tested the THCAD2 with a divider ratio of 1/128 and 1/64 already, but I can't remember if I also checked with 1/32. Will definitely try again.

I will also check the cabling again and the stability of the 5V power supply.

I think the frequency does not go to absolute zero but to less than 1 Hz (guess). I will also have a closer look at the duration of these drops. The EL5101 seems to provide some values for underflow, overflow and also the possibility to filter the frequency.

Warning: Spoiler!

};

I was also thinking of some moving average to filter the drops. But I don't know how I could implement this. Writing a custom HAL component?

Three axes moving. Not without a fight.
On enabling the servos, without me touching anything, the z axis would advance about 1mm, and trip out with joint follower error. Similar symptom to replacing an encoder and getting the a and b channels swapped. Took me too many hours to find in the heart of Tommy's tuning guide the answer, put a minus in front of the motor scale figure. (Required on all the axes.)
I've entered a default figure 20 for P and deadband.0001mm. Kind of surprised I cannot get it to error even at max jog speed.
Keep jacking up the P value, until it oscillates I guess, a job for another day.

The real time kernels run, they just don't "work" as in the latency for real time tasks is about the same as running a non real time kernel.

Ahh yes, apologies I did misinterpret.

Yes that would be possibly I think, I did not see this possibility when I was drawing out concepts.
It would require a fairly large (stationary) support structure outside of gantry support, and access to table would be limited a bit, but other than that it should work.

I did already buy all parts for the carousel and got all the aluminum plates ready to route the holes, but its a good alternative option without loosing work area!

I tend to think that EtherCAT doesn't add any timing constraints.
Worthwhile to do a test. But you can't run a realtime linux kernel in a virtual machine, can you?

Experimental. Perhaps too experimental. I just bought EtherCAT stepper driver Rtelligent ECT60 and used my own IO card.

It seems like you may be on to something, there is no pyvcp in that list. I have also added other photos in case there is something that may help.

Z probing with G38.4 was created by spontarelliam

Z probing with G38.4

Category: Advanced Configuration

I currently use a z probe routine that uses G38.2 to lower the tool into a metal puck until detecting continuity. This works 90% of the time, but there have been a few times this went wrong when either the wire to the puck had become damaged from use over time or the endmill had some plastic stuck to the tip or some resin from a wood cut, etc.

It seems much safer to manually drive the endmill down into the puck, then use G38.4 in the probe routine to move away from the puck. When I make this change and manually drive the endmill into the puck, I get a "Probe tripped during coordinate jog" error. Any ideas on how to avoid this error or how G38.4 is typically implemented?

Thanks!
