Hi Vasi, Vasi (and others), Happy New YearI
May the next Jallib release be the best release ever.

Double check things supplied at 5V connected with other things supplied at 3.3V...etc. The worst thing is when you have to deal with Chinese bandwidth (like Fnirsi DSO 110MHz say, 20MHz is...:o) Chinese watts or any other parameters you will wonder about... So. no big problem. Chinese cheap is expensive. Chinese hobby kits are fine. Hobby it suppose to modify and understand. Happy new 2022!

Free software, excellent modularity, excellent online documentation, huge blueprint "database". Instead of Arduino UNO R3, you can use a Nucleo board and gain in speed (with the required grbl version built for STM32) just by moving the shield from a board to another, matching industrial solutions.

I had to modify mine. I removed all of the ground-side pins from the jumper pairs, then made a wire that reached each stepper driver's remaining jumper pins. One end of the wire connects to the +5v on the board and each of the other three ends was soldered to a jumper, which allowed me to send voltage to one or two pins on each stepper (I was able to enable 8x microstepping, which was fine for me). As for the flaw that another buyer mentioned, with the "step" and "dir" pins being reversed, you don't necessarily need to modify the board for that. Just compile your GRBL with the "config.h" file listed in the link on Banggood's CNC Shield product page. Overall, I'm happy, now that I got it working. The Arduino and the stepper motors seem to be flawless so far. And it only took 2 or 3 weeks to get to Ottawa, Canada via regular mail, so that's not bad."

I usually do projects which are not readily available or far to expensive. The raspberry pi is my desktop computer, or a video player, or the more complex side of a project. My fridge, which is outside and needs heating in winter, is controlled by a PIC. It's connected to a Pi zero W, which acts as nothing more than a wifi interface to get the temperature curves to my screen. Yes, an ESP controller would do it, but that's a new world I haven't entered yet. You shoudn't compare the raspberry pi to a PIC controller. It is a (cheap and small and low-power) computer.

I bought a raspberry set with screen a while ago, but because it's very different from JAI, I haven't done anything with it yet beside running some ready-made programs on it. Can you give me some info how you did this? Op woensdag 29 december 2021 om 14:16:31 UTC+1 schreef Kiste: Hi Hans, jal is not the language to decode almost any files. It is solely for 8bit microcontrollers. Such a controller is an excellent choice to control stepper motors in sync with an engraving laser module, but not for decoding any data files. You would want something with more computing power, more memory and other kinds of interfaces. For decoding files, I myself would use a raspberry pi, connected to a PIC by UART. Then, I would transmit only simple actions like "go forward 300 steps, then turn on laser, go forward another 100 steps, turn off laser" to the microcontroller. On a complete little computer, there are libraries for decoding most file types you may want to use. The microcontroller then can do the swiching with fractions of microseconds accuracy.

I have not yet done anything with CNC etc. My question : Is there a Jal lib for CNC decoding or other advices?
