I am burning the board using ISP MKII which works fine (I only take th HEX file from the Arduino compiler and burn the file using AVR studio) this is the only way I can do it. I have built a PCB using AT2560 (blank) ion my board I went through the post and tried to understand what to do I've tabulated my findings so far below:Ī couple things to note: there are 11 ports ranging from A-L, excluding I. 8 axis, of course if ATMEGA 2560 will have speed for work that. New pin out now is on same port for all 6 axis for, step, dir, limit, relay and other, and have space for add max. Anyway, that's 17 PWMs that I can see, and only two of them coincide with communication pins (unlike the ATmega328, which uses half its PWMs for SPI pins. After that I m must make new pin out map for GRBL on ARDUINO MEGA 2560. It's strange, though, that pin 26 (PB7/ digital pin 13) has two PWM timers wired to it: 0A and 1C. b avcc pg5 pf1 pf3 pf6 pk1 pk4 pk7 pa0 pa2 c pe2 pe0 pe1 pf4.

Among the digital are four UART ports, one SPI port, one JTAG port, and I2C/TWI port, and several pins that can be used for an external parallel memory interface (16 address/data pins and three strobes). 2.3.3 Port A (PA7.PA0) Port A is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board. I'm pretty certain, then, that these pins can be used, giving us a total of 70 digital and 16 analog pins. The MEGA 2560 is designed for more complex projects. Why this is, I'm not sure, and these pins ARE used on the official MEGA. Not a problem! :) In that previous message, the pins_arduino.c says that just about every pin is available for I/O, the exception being PB6 + 7. On same time need be real and say that is very nice speed for diy machine if we look for price. 2000 cph and for 2 head maybe 3800 cph, and that is if you are very good on develop that devices and with hand for make that. in 3 out 42 mc33269st-5.

I not see reason for some big slowdown on work, because if I use 2 axis for 2 head, that cant work boot on same time, and for that is not possible have some big difference with some faster devices and with ARDUINO MEGA2560, I m not software developer and I not have experience with that, but I think that, all so is with relay, when you ON some relay for switch need some time for pick part and some for OFF relay, for place part, only maybe can be problems for process that code on same core on processor, can you please explain me ?
