Dear all,
I need your help because I can't solve some issues with this board. Last couple days I took hammer couple times to smash this board and give up in last moment to give it second chance. So, what is the problem?
I ordered 3 boards of pokeys57CNC to put it on CNC routers for stone carving. I using mostly CSMIO controllers ( CSMIO IP-M, S and A) but they have some issues with probing (G31) and my customer wants to have option for mapping surface (Autoleveller tool for probing). That is only reason to buy those boards.
First issues is with cable management, ant that is painful. In comparation with CSMIO it looks like toy.
That is not issue, I have huge problem with feedrate stability. It is impossible to get constatant speed. I will post YT video.



I put some feedrate 2000mm/min and it jumping from 1920 - 2050. It is noticeable in motor sound and machine moving. When you cutting stone stabile feeedrate is most important. Second issue is regarding to PWM turn of. It sometimes hapen in 15min and sometimes in 40min or after hour. Relay is still active and we broke couple endmils ( expensive one) due to this problem. Now we can leave machine because of this problem. I am 10 years in this field and beside of Chinese crapy boards this is first board which is unsolvable to me.
Thank you in advance.
