There's no reason for the calibration to ask you do measure backlash, as grbl doesn't have backlash comp built in. All backlash mitigation must be...
Yeah I second-second guessed myself because I was on the phone and apparently couldn't multitask. It should definitely complete successfully but...
That was my first thought, but if it sees a probe trigger through EMI, it should error 4, not 5? Edit: actually no, it should just successfully...
So to confirm, entering: G91 G38.2 Z-25 F60 G90 verbatim does NOT produce a meaningful result? Struggling to see what it possibly couldn't like...
The way it is in the picture has worked for decades for model aircraft- a hardwood LE butted against by balsa sheet for the surfaces. Whether that...
Would probably have to do it the way I used to do it before I started using LaserWeb more- use Fusion 360's 4th/3+1 milling features, then...
Yep, this is what I was gonna suggest- plenty of holes in those designs to add additional hold downs. Might be worthwhile, if you're making a lot...
Haven't cut much plastic, and what I have cut has mostly been urethane, which is extremely tolerant of cutter geometries, so salt to taste. For...
Sounds usable, but ugly. I'd bootstrap it before I did that- T-nut the rails to the extrusion for just long enough to get the machine working so...
Arduino only has three limit inputs, that's normal: gnea/grbl Yup! Same as all stepper drivers. Same thing is happening internally in the...
I was referring to this: Don't worry about the spinning, just keep it in "indexing mode" (which can also do continuous motion, of course). Let...
The BlackBox is basically an Arduino Uno and four stepper drivers in a box. It doesn't gain you an axis, because grbl is inherently limited to 3...
Gotcha. I think I can follow that easily enough. To include a Y axis, it may even make more sense for an extrusion build to run as a gantry...
Standard lathes have a single leadscrew on X (the cross slide). Not sure why you'd need two motors. Maybe if you post a diagram we could figure it...
Might not be as efficient, absorption-spectra-wise, but evidently it physically works. At least to the point of being worth researching how...
From simply Googling the model number, I'm gonna go with... Yes? NEW IPG Phononics PLD-70 fiber coupled 60w laser diode dpss cnc cutting burning •...
It looks like a better mounting location, rigidity-wise. Might be harder to tram in the rails and add any necessary shims once they're down there...
Great info! Appears to affirm both my general assumptions as well as my simulations, which is nice. Good orientation on the 2080 beam too. :thumbsup:
Indeed. The discussion- and fix for the OB grbl post, from @David the swarfer - can be found in in this thread in the remainder of page one and...
