Hello everyone,

here I made a 3-axis CNC with 3 stepper motors (Nema17) .. I control it with an arduino UNO (library GRBL) but I would like to replace the Arduino by a microcontroller 8051, more exactly a P89LPC952 / P89LPC954. So, I would like to control my CNC with the programming language in C.

Can someone please help me or if someone already has a C program to control a 3-axis CNC? : D

For you to have a little more information on my CNC. It is a CNC mainly designed to engrave PCBs. In addition, I use UGS (Universal Gcode Sender) to control my machine in G-code. here I think you have all the necessary information in any case!


thank you !

As I understand it, you want to use a P89LPC952 / P89LPC954 to receive G-code from
somewhere (a PC ?) and then drive the stepper motors on your CNC machine.

That seems to be a very complex task.
It will take a lot of work to create a system as good as you have now.
Why do you want to do that ?

It's exactly that !

it's my teacher who asked me to go to a forum and try to have the code .. as you say it's complex, that's why he asks me to go on forums.

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
