Newbie question probably asked a lot here.. Is there a way to save the machines(lead1515) zero position after powering everything down? I would think the black box would be capable of retaining that data..
Grbl automatically does that. Just rehome on power up to re-establish all stored locations back to physical space.
GRBL saves the offsets from machine home so after a home your offsets are exactly where you left them. It does not save '0', machine zero is set physically by homing (or faking the home), after that your offsets (work zero) come into play.
At work so I can’t look at the software right now.. what you’re saying is I need to set the “home”position as opposed to the “zero” position if I want a repeatable xyz placement( meaning after cycling power it will remember)?
Home first (establishes where in the real world the machine currently finds itself - ie sets Machine Zero) Then jog to the stock origin and ZERO using the SETZERO buttons to tell it where the Stock is (this is an offset from Machine Zero = work Zero) You need both, in that order, for it to persist Because the offset is automatically saved, once you re-home (setting up Machine coordinate system again as during power off it could have moved around) the origin (work zero) is remembered (and any other offsets, Work Coordinates G54 through G59.1, G29, G30, etc) See the video on docs:blackbox:hello-world [OpenBuilds Documentation] which shows you how to Home first, then setup Stock by Zeroing.
Good evening. You guys may know this already, but… In the video, he says a router speed setting of 3.5 is 12k RPM. If that’s a Dewalt DWP611, I’m not sure that’s correct. I think it would be > 18k. I could be wrong, but I wanted to mention it. Thx, rink.
Hey, Christian, good afternoon. Yes, you could be right. However, if the Mikita speed 3.5 = 19.5k RPM, and the Dewalt speed 3.5k = 21.5k RPM...then both of those are a long way from 12k RPM Maybe he was thinking about a spindle instead of a router? Thx, rink.
