Hi, I am facing issue with the cutting of the new CNC router that I have been building. The CNC cutting starts fine and cuts the material fine initially but a few parts are cuts it starts loosing path. Some pictures of the same are as below: The specs of my machine are: I am using Arduino UNO with Arduino CNC Shield. The drivers for the steppers that I am using are DRV8825 (running at 2 amps) I have tried this ChiliPepper and GRBL Panel Router - Makita RT0700C I use Eased Some observations: After the cuts start going wrong restarting the whole setup again, results in it going wrong almost right from the beginning. Waiting for a while seems to make it better. The drivers for the steppers that I am using are DRV8825 and they have heat sinks and I am using forced cooling. These do not seem to get hot during the operation Additionally before I added a router to the setup, I did several dry runs by mounting a pen and never had any problems. Some of the drawings took a almost a couple of hours but this problem never happened I rechecked the wiring, the smooth movement of the gantries, cut material clogged in between the bests but none of them seemed to be an issue. The first cut I did was: using a design in Easel and the GCode was generated using Easel only Router used was a dremel This cut went of fine For the current cuts (where things are going wrong), I am using: Makita RT0700C for the router Drawing are in ACad and Estlcam 9 for CAM CNC program generation is using GRBL I have tried this Gcode generated by Estlcam using both ChiliPepper and GRBL Panel. however in both the cases, the issue is the same Appreciate help/ pointers from the forum to give ideas on how to resolve the issue.
