Hi everybody. I'm a beginner in G-code. I'm working on a Workbee 1010 with 1.5kw spindle. And I have a problem : My first try on the machine is with the Hello World example. It's set with a speed of spindle : M3 S1000 (G-Code) that's working. but just after, the speed of the spindle decrease and I can see the spindle rotate very slowly during the next code lines. Have you a solution to keep the rpm ? Regards, Jeremy.
You need to set your Grbl params to match the actual spindle Max: See gnea/grbl For example if your spindle tops out at 24000rpm, set $30=24000 Then if you want 10000rpm, you send M3 S10000 And then you can fine-tune your 0-10v if its a little off still: See docs:blackbox:connect-vfd [OpenBuilds Documentation]
