1 year ago Did you modify some speed parameters on firmware?
Please try to update default firmware without modifying any parameters.
Belt or screw motor? If it is a screw motor, ensure the smoothness of the screw.

Hi all! On my MKS DLC32 V2.1 board, the PWM output signal decreases when both axes are working, the higher the speed - more than 10 mm / s, the more the voltage drops between the S and TTL pins. Diver TMC2209. Nema 17HS4801. Everything is fine when it cuts while moving along one axis - vertically or horizontally. If you lower the speed to 10 mm / s, then the voltage drop is almost not noticeable. There are no problems with Gcod, since it works correctly in another GRBL / controller. There is no interference or interference either, since I tried to disconnect everything - nothing has changed ... I tried changing the power supply from 12 to 24 volts, it did not help either. I thought something burned out in the board and bought a new one, with the new one the same problem ... Nobody faced such a problem? GRBL setting. $0=10 $1=255 $2=0 $3=0 $4=0 $5=1 $6=0 $10=1 $11=0.010 $12=0.002 $13=0 $20=0 $21=1 $22=1 $23=3 $24=300.000 $25=1000.000 $26=250.000 $27=5.000 $28=1000 $30=1000.000 $31=0 $32=1 $38=1 $40=1 $100=80.000 $101=80.000 $102=80.000 $103=100.000 $104=100.000 $105=100.000 $110=3000.000 $111=3000.000 $112=6000.000 $113=1000.000 $114=1000.000 $115=1000.000 $120=500.000 $121=500.000 $122=500.000 $123=200.000 $124=200.000 $125=200.000 $130=450.000 $131=450.000 $132=50.000 $133=300.000 $134=300.000 $135=300.000
