I am runing my MPCNC with Arduino mega + Ramps 1.4 + LCD + Marlin 2.0 Bugfix (downloaded from github - MPCNC_Ramps_T8_16T_LCD_32step_DualEndstop ). I milled few parts out of wood with this machine and i am very happy with results. But some parts i cant mill or carve properly. I am using Estlcam for generating G-code (enabled G2 and G3). The simulation in Estlcam is showing proper path, but when i start it on MPCNC via SD card, the path is diferent. It moves in strange ways with some fast movements. (The Zero origin is set in the middle of carved parts, so there are also negative values in the Gcode). I tried the same G-code with diferent firmwire (link from youtube - https://www.youtube.com/watch?v=jlOyqca9AqM) and it works properly. But both firmwire are based on Marlin.
What could be the problem for this? In attachment is example of G-code
Thank you in advice.
