I’ve actually created a process for this, but I figure I’d ask those with much more experience if there is a “right” way to do this.
I’ve got my spindle working through an RS485 interface. However, I have it set to take 7s to spin up to speed.
Is there a way to tell Estlcam that the spindle needs this time? Or is it proper to insert a G4 P7 after the M03?
If you have the vfd connected tru rs485 you dont need anything on to cam to figure that out: if you are running with the jackpot controller: just verify you have the vfd programmed as it should ve (check FluidNC wiki, copy the correct config to your config. Yaml and the vfd config.) that should ve everything
Thanks Cesar. It is a little more than that, but not much. It turns out that it helps to explicitly turn off laser mode with $32=0 in the preamble text in Estlcam. Otherwise it may start trying to vary the spindle speed in strange ways. I ran about 4 cuts before it started acting up (and I hadn’t done anything with the laser yet.)
It would spin the spindle up, but if the first hole was very close, it was clearly still not at full speed when it did its first plunge. However, in trying to learn to do it right, I switched to a drill bit for some of my holes, and I really turned down the rpms. That put me in a state where the VFD was reaching its low limit and alarming. Then I noticed that it would spin faster during travel than when cutting. So I did a little research and stumbled on the laser mode issue that sometimes rears up in grbl. Anyway - it appears to be solved for me now.
Mm weird, i use mine and i have a laser declared and never had that issue. I did the config as they say in the spindle section of the fluidnc wiki, programed my vfd as they say and it just works.
But glad you sorted that out. Enjoy your machine
The Estlcam controller uses a configured spindle delay setting. For Marlin it looks like a G4 S7 (S = seconds, P = milliseconds) added to PP Texts after M03 in Start and Tool change would work.
