![]() ![]() TMC2130, TMC2208 and TMS2209 usually have 0.11ΩĪs an example, if you set by mistake the sense resistor to 0.11Ω instead of 0.051Ω the real current of the motor will be more than double, and the power injected in the motor more than four time higher, yes you read it correctly FOUR – AKA 4 times higher. Please make sure the sense resistor is set according to what you have on board. ![]() Pressure_advance_smooth_time: 0.03 #to be calibrated Pressure_advance: 0.025 #to be calibrated ![]() Nozzle_diameter: x.xx #define nozzle diameter M572 D0 S0.02 pressure advance – to be calibrated M906 E1200 I10 motor current 1.2A idle current 10% M566 E300 instantaneous speed change mm/min M92 E690 steps/mm – you may need to finetune it M350 E16 I1 micro stepping set to 16 with interpolation To reduce clicking noise of the extruder (due to fast direction change) you may limit acceleration to 3000mm/s2 Adding weight of the filament it drags along its recommended to have acceleration limit set not above 8000mm/s 2. * The extruder itself without filament can handle acceleration up to 25000mm/s 2.
