Below is the list of default GRBL settings for the Sainsmart Genmitsu 4040 Pro should you need to restore them to the factory originals.
Most of the settings you will never need to change. A couple that I have changed are listed at the bottom.
| $0=10 (Step pulse time, microseconds) |
| $1=25 (Step idle delay, milliseconds) |
| $2=0 (Step pulse invert, mask) |
| $3=4 (Step direction invert, mask) |
| $4=0 (Invert step enable pin, boolean) |
| $5=1 (Invert limit pins, boolean) |
| $6=1 (Invert probe pin, boolean) |
| $10=3 (Status report options, mask) |
| $11=0.010 (Junction deviation, millimeters) |
| $12=0.002 (Arc tolerance, millimeters) |
| $13=0 (Report in inches, boolean) |
| $20=0 (Soft limits enable, boolean) |
| $21=1 (Hard limits enable, boolean) |
| $22=1 (Homing cycle enable, boolean) |
| $23=3 (Homing direction invert, mask) |
| $24=100.000 (Homing locate feed rate, mm/min) |
| $25=500.000 (Homing search seek rate, mm/min) |
| $26=250 (Homing switch debounce delay, milliseconds) |
| $27=1.000 (Homing switch pull-off distance, millimeters) |
| $30=10000 (Maximum spindle speed, RPM) |
| $31=0 (Minimum spindle speed, RPM) |
| $32=0 (Laser-mode enable, boolean) |
| $100=800.000 (X-axis travel resolution, step/mm) |
| $101=800.000 (Y-axis travel resolution, step/mm) |
| $102=800.000 (Z-axis travel resolution, step/mm) |
| $103=177.777 (A-axis travel resolution, step/mm) |
| $110=2000.000 (X-axis maximum rate, mm/min) |
| $111=2000.000 (Y-axis maximum rate, mm/min) |
| $112=2000.000 (Z-axis maximum rate, mm/min) |
| $113=1000.000 (A-axis maximum rate, mm/min) |
| $120=20.000 (X-axis acceleration, mm/sec^2) |
| $121=20.000 (Y-axis acceleration, mm/sec^2) |
| $122=20.000 (Z-axis acceleration, mm/sec^2) |
| $123=20.000 (A-axis acceleration, mm/sec^2) |
| $130=600.000 (X-axis maximum travel, millimeters) |
| $131=500.000 (Y-axis maximum travel, millimeters) |
| $132=110.000 (Z-axis maximum travel, millimeters) |
| $133=9999.000 (A-axis maximum travel, millimeters) |
These are some of the settings I have changed so far (20 February 2023) and everything is running ok. You change these at your own risk and if you notice any issues then start by reverting these.
| $1=255 (Step idle delay, milliseconds) – This should help to hold your motors in place |
| $110=3000.000 (X-axis maximum rate, mm/min) – This increases your fast travel when moving between cuts, lowering job times |
| $111=3000.000 (Y-axis maximum rate, mm/min) – This increases your fast travel when moving between cuts, lowering job times |
| $120=100.000 (X-axis acceleration, mm/sec^2) – This increases your acceleration, lowering job times |
| $121=100.000 (Y-axis acceleration, mm/sec^2) – This increases your acceleration, lowering job times |
| $122=100.000 (Z-axis acceleration, mm/sec^2) – This increases your acceleration, lowering job times |

Thank you James open builds had changed a lot of the settings. After i had reset to the factory settings above it now works perfectly.
