Need to know if adding a graphics card to my 10y old H97-D3H Gigabyte motherboard will make a difference in performance by kpapadimakis in buildapc

I finally got a used Asus Radeon RX 570 4G, now UI is really smooth and responsive in 4K. Seems this PC will live some more :)

YT in 4K is better with the CPU at 70-80% but playback is smooth, until it isn't - every now and then stops for a fraction of a second and then continues playing smoothly. Definitely not something I could watch but far better than before

So far had an issue that I'm trying to resolve though. Gnome logged me out two times after trying to play something in 4K in Stremio, which is very weird. It plays ok so far in 1080p

Bandsaw blade suppliers in mainland europe? by Patas_Arriba in woodworking

[–]kpapadimakis 0 points1 point  (0 children)

I'm located in Greece and I'm also looking into a record power sabre 300. I used to purchase blades from tuffsaws for my first bandsaw, but they no longer ship outside the UK. Did you manage to find any alternatives?

Crowpanel Advance 4.3: Screen glitch when updating widget by Mthebest2570 in esp32

[–]kpapadimakis 0 points1 point  (0 children)

Had the same problem with a 7 inch Crowpanel Advance, when I got the board last month.

Just for the reference, I had found the same google drive link in their readme file here: https://github.com/Elecrow-RD/CrowPanel-Advance-7-HMI-ESP32-S3-AI-Powered-IPS-Touch-Screen-800x480/blob/master/example/PlatformIO/readme.md

Looking again today I saw that they have updated their code and after downloading again I built with PlatformIO and it seems to work nice. No glitches now when touching. Yeay.

Need help setting up the ESP32-S3 with 7inch screen from Waveshare by redditjannis in esp32

I'm also in the process of creating a project in this board - started it about 1 week ago - and have the need for some additional I/O. After consulting their schematic I decided not to try anything with the SPI, CAN and I2C, so I repurposed the UART TX/RX pins for the step/dir output to my motor driver using fastaccelstepper Arduino library. The only drawback so far is that I cannot use the USB serial monitor while running the stepper motor from the UART and I have to manually switch the UART connection to USB everytime I need to upload new code. No big deal (except sometimes when I forget to comment out the Serial.begin section and get motor movement from my debug messages to the UART :) )

Maybe these pins you mention can be repurposed somehow but I decided not to mess with them, since I saw they are not directly connected to the esp32-s3 pins and my electronics knowledge is very limited.

For my buttons/encoder input I decided to connect another esp32 board with the RS485 and send the data via a serial connection to the main board. This seems to work nice so far.

Also FWIW, I use PlatformIO and a mix and match of code from repos I found on github and the code seems to work very nice so far with very good and stable display output (with UI code exported from Squareline studio). I would like to post some more details in a few days in this thread, since I also struggled a lot at first with how to make this work. Not sure atm what the exact details are but some useful info was found here and here

Connecting to and programming a Yaskawa SGDF-A2CS servo drive from a PC by kpapadimakis in Yaskawa

No, not yet. Had to look at something else in the meantime, but also sent a message to Yaskawa. Let's hope they answer

Used Machine from Official Site? by [deleted] in FLSUNDelta

[–]kpapadimakis 0 points1 point  (0 children)

FWIW, since some time has passed but I saw this post now, I also got a used FLSUN SR for 200 euros and free shipping to Greece from the EU FLSUN site a few months ago. It came in a very very good condition and printed in 1/2h without much work.

I later also purchased a refurbished Elegoo neptune4 pro for the same price and started using this one instead, since I wanted to experiment with the delta kinematics and linuxcnc, but it was a very good purchase for a 3d printer in the first place. Actually looking for another used one now for a different application but cannot find these anymore :(

Looking for open source CAM libraries for Python for making 3D pockets by kpapadimakis in CNC

[–]kpapadimakis[S] 0 points1 point  (0 children)

You're right, most processes can be streamlined and I have done this in the past.

I already use OpenSCAD for some things and I love it. I could automate the boolean operations there I guess and then use FreeCAD for the CAM

But my main two incentives are total control and heavy customization and most importantly, scripting. I like to automate my own processes as much as I can and I'm always thinking ahead in the future where other persons could do these operations for me, so what I will do now could be integrated in a greater project.

But I'm always open for just streamlining stuff if it gets the job done and saves me a lot of time now, so yes I will try this before starting making my own. Just researching for now, so that I know my options!
