Need help in choosing controller board from small honby cnc.

Initially encoder, PWM etc can be used via digital pins. As I was using. But please increase digital input. You can reduce digital output. Machine needs more input pins than output machine. 8 for endstop, 1 for probe, 1 for Estop. 2 encoder. 5 pins for axis selector, 2 for scale selector. Total 19 pins. If someone wants to use hold/resume.

 

I dont think you can just reduce one for the other, but its also something I wouldnt know how to do anyways. which is why I keep suggesting to you, that the you should keep using the version you have now.

Help me out in physical Estop button on MPG controller. I want to use estop button so that I need not to press estop and machine enable button in GUI. I have made hal config so that when I press estop in GUI machine is also enabled. But I can't do it buy releasing estop on pendant.

I have 5 axis machine and don't plan to go for 6 axis. I want to use sixth axis select button on MPG for feed override using rotary.

One more question. Should I buy stlink adapter as seen in your ec500 video to flash EC500 or I can do this with USB to UART adaptor? How can I backup my original flash so that I can revert back of I need it. I have v5 version of EC500 with iMXrt 1052. 

It would be great if you and terje collaborate in making grblhal working on this board. Its easily available and have plenty of io with MPG and Ethernet. One use as LinuxCNC or grblhal. I think this board is much better and cheaper than other options available. Also with 600mhz cpu.

im not really involved with the rt1052 project, i just do techsupport sometimes. I dont think it is optional, you need the stlink.

you can refer to this for flashing firmware etc,
