Just received my 1F a couple of weeks ago. I was a CMM programmer in a previous life. This video answers some of the questions I had in the similarities between the machine code for CMM programming and Gcode. Keep bringing the great content! Thanks CRG.
Great video explaining MDI. At one point you mentioned that you routinely stop long carves (especially with epoxy). Do you completly shut down then use MDI to set the start position when resuming? I would love to learn more about that practice. I currently pause my 1F but not overnight. I have a longer carve coming up and it will take a full 8 hrs. I would love to stop in the middle of a 3D finishing pass. Thank you
Hi Mike - thanks! Yes, I turn it off completely between runs -- **before** turning it off, I write down the absolute coordinates for the zero position. The next day I re-home and re-zero to the coordinates I wrote down (using the MDI interface), then I do my next series of cuts. The OF has fairly good repeatability with homing (I did a video on that as well), so you can get within 5 thou of the original position, which is good enough for what I was doing. If you need more accuracy for some reason, then leave the machine in the zero position when you turn it off, make sure no one touches it, and when you turn it on again it will be in the right position -- immediately zero without homing. That gets a little sketchy since the machine doesn't know where home is, but you can start cutting from the exact zero position each time. Hope that helps. Thanks for watching!
Hi Jonny - great question. In short, after you home, the machine will set x,y,z to zero. It is a known location the machine can return to at any time. However, you don't always want your machine to start cutting at the home position since your material might not fit there, or you need to start at an alternate location. As such, you can zero your machine at any location, essentially creating a secondary position that is relative to your stock or material. Further, not all machines have automatic homing, and in that case, you are stuck with zeroing the machine each time. I hope this helps -- thanks for watching!
Not with the Onefinity, but you can with some machines. It really depends on the controller and how it feeds commands to the machine. The OF locks out the MDI while automated files are running. With the X-Carve, you could use the buttons on the controller to change the feed rate. Thanks for watching!
Tanks a lot for the explainations ! Do you know how a Onefinity would be moved in "machine' coordonnates ? I would want to move to the rear right corner after a job instead of the front left homing position and I can't figured it out... Help ! :D
Hello. Any positioning of the machine after the job is complete is usually put into the gcode by the post processor. Onefinity does not home after job complete by default. As such, look into your post processor and replace G28 with your coordinates. Hope this helps -- thanks for watching!
@@cyberreefguru Guru ! I need your help ! I calibrate my 1F based on the probe cube. It worked fine, moving 60mm gives me 60.07, I can live with that. Problem is all my fusion toolpath gives me smaller pockets than expected : a 20mmx200mm pocket gives me roughly 19.74 on both axis and 'stock to leave' is unchecked. I can't figured it out.... any pointers ? much apprechiated
I thought that this was going to be about mapping the contour of the surface and compensating for it during carving - G29 / G420 or whatever. Silly me... :/
Hello Roger -- no software will automatically generate gcode from a 3model (and get it right). It just doesn't work that way. You can output your model as an STL and then import it into Fusion and do 3d tools paths as necessary. Sorry, but there is no 'easy' button for CNC tool paths. Thanks for watching!

Excellent! Thanks
Thanks for watching!
Thank you for your excellent videos. Why can’t Home be made to be x=0, y=0? What, if any, is the advantage of Home and 0,0 being different ?

@@cyberreefguru Yes, thank you!
Nice Job. Can you enter an Fxxx while a job is running to change the feed rate?

@@cyberreefguru gonna try that. thanks a lot !
@@cyberreefguru I've manage to make it work thanks to you. Many thanks
@@daganael Glad you figured it out - best of luck!

Not quite, but I can add that to the list of future videos :) Thanks for watching!
great, any open source can translate 3dmax to G-code?
