Config of Spindle min/max has no impact

[bullar]

The setting of spindle min/max in config has no impact on min/max slider values in Spindle control
There min is fixed to 1000 and max stuck to 31250 RPM.

Is there any trick to overcome this issue?

Can you give us more information, like firmware flavour, board type, etc.?

Gsender 1.5.x current to SLB in Windows and mine doesnt work either. Sliders or buttons dont change feed or speed.

If the min/max values are set manually in console ($31=5000, $30=12000 in my case) then the correct values are shown in gSender. Looks like gSender reads the values from firmware but if you update via config it doesn't change them in firmware. At least in my case...
@itsnotlevel1 with correct values the slider changes the spindle speed accordingly.

tested on:
LUNYEE 3018 PRO ULTRA
Firmware: Monport [VER:1.1f.20230316:] [OPT:VMZHL,35,254]
gSender 1.5.6 on RPI4 connected via USB to LUNYEE (Grbl)

Okay I think I get what you're saying I had to read it three or four times, because I'm dumb 😆, in order to get what you were saying. I'm going to try a couple things tomorrow I'll reply back to this whether it works or not. Paul Sent from [Proton Mail](https://proton.me/mail/home) for Android.
