Hi !
I use acs724 +/-10A to measure stepper motor current.
120kHz analog output, 1us rise time. 5V supply voltage, 2,5V output offset (0A), 200mV/A.

Hi!
This project is an experiment. To learn its limitations, pros and cons. It have some great benefits and some down sides as well.
It certainly changed the way I think about motion controll....

Feedrate test. mm/min. For screw 5mm pitch. Exact stop mode, spread cycle.

Second try. Full SPI MODE 1.
-power supply 1A 24V C.V.
-tmc5160 spread cycle, stealt chop, 0,5A max
-Rsens 0.022 R

First run in FULL SPI MODE 1, with standard setrings, not matched Rsens (0.022 R), 17SH4401 (1.5 A). Ideal Rsens for this engine : 0.15 R.

I think I won't find much enthusiasm in this project by majority also !
But I don't think I overestimate speed (and when I mean speed I don't talk about just motor speed) it is important in many...
Hi ! I didnt want to brag aboit it. I see that many people just love it! I was talking about my personal experience - and also I tried bunch of senders and control software for microcontrollers.
I...
Hi ! PC runs g-code sender - this programs monitors and established USB connection with microcontroller, and sends sends strings of g-code to it. It isnt computing g-code just sending. When...
I'm sorry, but from my personal experience bcnc was terrible to use (tried it not so long ago). And also it has many issues on arch based distros (and other too).
Sender is simple software, its...
Hi ! I'm using and contributing to open source projects. And they all are mostly software based. This makes them more portable to different hardware bases. But ... It makes them so slooow. My goal is...
Can't edit first post.
What are my goals with this project:
-RESPONSIVENESS of the multiplatform GUI g-code sender, writed in python - and using only native modules, with low CPU usage
-SPEED of...
Hi, im trying my skills and will try to make G-code interpreter and G-code sender from scratch.
