GRBL_SPD for Makita Routers

looks like there’s another method, I haven’t tried it yet myself:

FluidNC support · Issue #283 · OpenBuilds/OpenBuilds-CONTROL

Code:

change the startup message.

Changing the startup string to Grbl \V [\H] 

 

Do you mean the FluidNC ID string or actual firmware?

ps, I’ve got FluidNC mostly working now.

Tbh, I couldn’t find any guides on configuring and compiling any normal versions of GRBL so I went with FluidNC.

@Peter Van Der Walt do you know of a good guide for grblHAL? I'm curious to test it out but I can't really find any simple guides for idiots like me. There seems to be eleventy million options, but no concise guide for noobs.

The web builder looks good, but doesn't let me specify a PWM spindle, or much else.

 

@Peter Van Der Walt I finally got my head around grblHAL - although I did end up needing "Config App" from ioSender to configure it as OB Control isn't fully aware of it it and thinks it's regular grbl.

GRBL_SPD works very well in grblHAL with the following config:

Code:

$30=30000.000  ;  Maximum spindle speed, RPM
$31=10000.000  ;  Minimum spindle speed, RPM
$32=0  ;  Laser-mode enable, boolean
$33=1000.0  ;  Spindle PWM frequency
$34=0.0  ;  Spindle off Value
$35=2.0  ;  Spindle min value
$36=100.0  ;  Spindle max value

 

Ah right, I’ll double check as I can’t recall eat setting I used.

 

i don’t think I did compile it with any compatibility settings on. Maybe I just found the OB settings hard to understand compared to Config App.

 

Hmm, maybe it’s dark mode making it hard for me. The rest of the UI is great, but I found the settings page less clear. Settings are too spread out and not grouped logically.


This is config app - it’s logically laid out and has generally great explanations of the settings. It’s not pretty, but it’s actually easier to use.

 

GRBL_SPD v4 is about to be released and I was lucky enough to get one for testing.

Introducing GRBL_SPD v4

 

There's no reason it won't, assuming the Duet has a 5v PWM pin it can control as the "spindle" and set 0% = Off, 1% - 100% for 10k-30k RPM.
