Seeking Assistance with adjusting minimum speed on CNC3018 pro #1250

Hello

I am currently using the "Grblcontrol (candle_1.1.7)" software for my CNC3018 pro (Mostics). I have configured the following setting in the console box:

$1=25 $2=0 $3=3 $4=0 $5=0 $6=0 $10=1 $11=0.010 $12=0.002 $13=0 $20=0 $21=0 $22=0 $23=0 $24=25.000 $25=500.000 $26=250 $27=1.000 $30=1000 $31=0 $32=0 $100=800.000 $101=800.000 $102=800.000 $110=1000.000 $111=1000.000 $112=600.000 $120=30.000 $121=30.000 $122=30.000 $130=200.000 $131=200.000 $132=200.000

With these setting, when I send the G-code G1 Z-10 F3, The Z-axis moves downwards at a rate of 3mm/min, which is as expected.

However, when I issue the command G1 Z-10 F2, The Z-axis moves downwards at a rate of about 2.3mm/min, which is not the expected 2mm/min.

In an attempt to lower the minimum speed, I adjusted the $112 from 600 to 60. Despite this change, the lowest achievable speed remains at 2.3mm/min.

I apologize if this question has been asked before or if the answer is readily available. I would greatly appreciate any insights or suggestions on how to effectively decrease the minimum speed. Thank you in advance for your time and assistance
