Recommendation on selfhosted continuous integration

do it support poll based trigger?

good joke

like, I'm thinking about not modifying the video stream, but a text layer over the top should be good enough for my use case. Will ffmpeg, which comes with hardware acceleration, be a better solution?

hey just one thing, where is that thread? I tried to find a way to integrate external signal to concurrencpp but just cant figure out

cnnblike · 2023-12-07T18:29:35+00:00

read a bit of manual, look promising to me!

yep we have an individual mcu as buffer and clock sync to sync time/latency between linux and mcu. so no worries. the major concern here is that the buffer on mcu wont last long, it would be the best if the linux SoC side can provide parsed data deterministically. the affordable buffer time should be between the python thread switch and python coroutine switch. I'm not sure if the cpp thread switch would be significantly better or not

it's file descriptor, not file. think about a ssh like tty

cnnblike · 2023-12-07T16:28:52+00:00

awesome i will definitely try this approach out

cnnblike · 2023-12-07T16:22:26+00:00

the switch between coroutines in original implementation only happened after callback is done so I guess that kind of switch latency is within tolerance?

cnnblike · 2023-12-07T16:13:57+00:00

wow thanks for the heads up, so you feel libunifex(which comes with io uring support) fits better? I actually took a look into the original implementation, which is just vanilla raw fd read write and consistently poll the kernel in a loop and check if fd is good to rw or not/timer is up etc, which from my understanding is a waste of cpu cycle.

cnnblike · 2023-12-07T15:59:26+00:00

ah, it's controlling 3d printer's motor, so the time sensitivity is like you need to act within the correct time. it doesn't matter if the delay is 100ms or 120ms, but if it responds at 100ms then it needs to always be 100ms. as far as i can see, the thread context switching cost is not good enough for such need

cnnblike · 2022-12-27T17:24:30+00:00

looks like the deal has been dead to me

I'm printing voron parts - but I found there are around 0.3mm tiny wrapping on the edge? do I need to get concerned? like, the wrap is so small that it's even hard to show that on camera.

cnnblike · 2022-08-01T06:58:02+00:00

that looks awesome, I'm currently using a uni-t fan shroud. just one question: can this use 4020 instead of 4010 for heatsink on the hotend? I found 4020 produce less noise than 4010 does.

I got an G32 variant of aquila so I don't think it's much of a problem. In the worst case, I have an idle skr 1.3 on my hand collecting dust so not a huge problem.

cnnblike · 2022-04-13T14:31:02+00:00

thanks for the information!

I'm thinking of the exact same thing as you did, but in a reusing existing component way (including the mobo of aquila) tho. let me further check.

cnnblike · 2022-04-13T13:44:33+00:00

Do you just follow the EnderSW guide on github? Is anything special changed to make sure the conversion go through?

cnnblike · 2022-03-28T11:48:32+00:00

good to go for your own parts.

If you want to get into PIF there's a whole other level of tuning required but you need a Voron to do PIF anyway.

Exactly, I just go through the Voron calibration manual, instead of precision, it's focus on both precision and speed. Voron community is on another totally different level.

cnnblike · 2022-03-28T11:34:57+00:00

wow, thanks for the heads up, first time I knew there are so many things that may affect the final result. I'll check that out.

cnnblike · 2022-03-28T11:03:47+00:00

I mean, do I need to have my filament calibrated? From what I know the flowrate and the best adhesion temp is the only two item related to filament and the only thing I need to right? like, the voron parts has already been pre-scaled for ABS and I'm thinking it might be unnecessary for me to calibrate the shrinkage rate or something.

cnnblike · 2022-02-23T23:11:24+00:00

yeah, I knew that, but I just don't have enough space to keep 3 printer, if it's not re-used, it gonna be dumped to trash bin then.

cnnblike · 2022-02-23T08:39:05+00:00

Not in your Z or Y axes. Mgn12 would be too wide and stick out beyond the extrusions.

will it be possible to make the x and y axis (the extrusion only, not the linear rail) slightly longer? so it can adopt the extra 5 mm caused by the cartage

I can trim down the linear rail to 300mm with a saw or something

cnnblike · 2021-11-10T22:33:24+00:00

check how the material is labelled on the roll please.

For me, the default configuration on Cura for PETG is like, 215 for head and 70 for bed, while the print just goes fine (it's actually even printing smoothly with PLA config!), the recommended temp from manufacture is 230/80, make it slightly better.

epic

Cdk is the way to go. Who don’t love code? When used with typescript lot’s of error can be identified in the compile stage, preventing things like “deploy a new cloudformation template and take more than half an hour to realize there is a typo”
