180 arcs do work in GRBL but as they get smaller you need more and more precision in the end points and center offsets. SketchUcam does use 180...
It sounds like you are sorted now with the Openbuilds POST, but just FYI there is a setting in the default Fusion360 GRBL post processor for 'Safe...
If you flash the 4-axes firmware from CONTROL > Wizards and tools > Firmware flashing tool > Machine Style > 4-Axes it enables the A-Axis buttons...
Fusion360-Grbl/Grbl and in the property list in the Post Process page the green colored letters there is a "Safe Retracts" its just says G28 So I...
That long comment is a result of the new restrictions on 'personal' fusion360 usage licenses, you shoudl have got an email from them about 3 weeks...
That didn't fix it, also I am able to simulate with machine still but the gcode still doesn't do the same thing as the simulation, it has no idea...
Hi, Need help with V3 controller. Having a hell of a time with this thing, bought it on the BF special. Also about 4 months new to CNC. This is my...
By the way what grbl board do you run and recommend also what sender software are you using and do you recommend. My current machine is just a...
here is a good primer on arc coding, more than you need to know, CAM is much easier, much quicker and much more robust (ie once the CAM is...
router UP is the Z axis 0!!!!!! that way the Gcode can do safety moves at or near Z0 and avoid hitting things on the table. for more info Home,...
Hi Peter, Thank you for taking the time to reply and for letting me know both about the post processor and that I should home the machine each...
Hi GRBL regards a hit on any limit switch as a hard limit and will then stop with an ALARM. This is mainly because the Arduino Uno does not have...
Thank you!!!
Thanks for reply, so when my machine homes to the offset positions I have it set to resset machine coordinates to zero. The screenshot of the...
Hello I did the update of the GRBL post-prossesor to V1.0.37 and a redid the job. But got the same error and this time de plasma cutter was off....
I'm reasonably familiar with Inkscape, however I've never used it to generate GCode (I presume you're using the 'gcodetools' extension?) From...
This is awesome! Before I made this post, I googled all these commands to "see" what was going on and I'm happy to see that my notes match...
Depends on what exactly your widget is: option A something with complex 3D shape and curves on the top option B an essentially flat thing with...
There is the problem. That post is written by people who have never actually run a GRBL based machine, so is theoretically correct but in...
in your image the arc has a radius of 0.64mm. As the radius decreases, the limits of accuracy of the endpoints approach rapidly. The best fix...
