the other thing to try is to check your lead in and lead out radii. fusion likes to use a formula that produces a radius that is a small fraction...
that one has been superceded by the OB post, please update (-: yes it works with any Fusion license level See docs:software:fusion360 [OpenBuilds...
I dont know, I have yet to fire up grblHAL on 'something'.... however, the next version of the Blackbox might be a 32bit processor running...
which direction were you cutting? clockwise or anticlockwise?
Yes, you are banging a limit. putting your numbers into GRBL settings calculator using the 'Z' section 8mm per rev 200 steps per rev motor *8x...
and if the drive sprocket is not exactly centered you will get cyclic variation I think, because of the radius variation.
Then I believe you need a 9v wallwart to power the arduino via its barrel connector socket. connecting the arduino to the stepper power supply is...
This means your X and Y are reversed from what they should be, arrows below show positive movement directions. [IMG] open OpenbuildsCONTROL...
a - the device at the end of the chain experiences more noise and voltage drop than the others because the others use power, or inject noise,...
a single output will suffice, but do research 'star grounding' and use it and also wire each driver seperately to the power supply (ie no daisy...
please do this: jog to the middle of the machine. setzero X and Y at this point (and Z if you like) select the serial console tab select the edit...
I had exactly this with a wireless mouse a couple of years back. I have been using a wired mouse ever since without issue.
maybe you clicked the setzeroY button between jobs? or maybe you fusion jobs have diffrent WCS settings, say G54 for 1 and 2 and G55 for op3
I believe you should increase the pulloff setting gnea/grbl
yes. Fusion360 adaptive toolpath with small retract height during those short rapids as it repositions for a cut. Z rapids up, XY moves, Z...
make sure GRBL's $30 and $31 parameters are set correctly.
my reaction is 'sticky spot'. that is what my machine did at first, Vslots and belts and I tuned X and Y to 7500mm/min but was only moving on...
Also note that in GRBL moving to X0 (or Y or Z) WILL hit the switch and cause an alarm. This is why the OpenBuilds Fusion360 post will output...
When GRBL does a homing cycle it finds the limit switches just fine and hitting them is not a fatal error 'during the homing cycle'. After that...
