If you have the real Protoneer CNC shield, here is a place to start Arduino CNC Shield – 100% GRBL Compatable. He started with an open source...
How do I know about the broken tap issue...:banghead:
No lock collars. I actually took the set screw out, drilled a small hole almost through the lead screw using the set screw hole as the guide -...
Those nuts are a great find. When I was looking 3 years ago, those we're not available. That would have saved me a lot of time.
You will most likely need to fabricate an anti-backlash nut (and tap) that will fit in the channel. That is what I did. Or you can come up with...
Instead of another under powered xpro, why not get the DQ542MA drivers, they cost about the same. The current xpro you have may be able to drive...
Here is a method I started using a while back and it works well . I see now NYCNC is doing it so it must be ok.:)If I want additional security, I...
What is your microstepping set at?
I believe others have used those with success. Here is a post/thread that may help you. Stepper motor won't move, any suggestions? (Solved)
I have found that I can engrave any text with F-engave, a free software. Much easier than F 360 (IMHO). Sometimes a complex .svg with lots of arc...
I drew this one from the step files in the resources section. Double check it though. I loaded the .step into fusion 360, converted it to a .dxf,...
I switched to the DQ542MA drivers and have not looked back. My fear was that I would be running a long job and at 90% complete they would...
I love using Fusion 360 and Estlcam. Since most things I cut are 2.5 D, I do not usually bother modeling in 3D. I just do a quick drawing in...
I had problems with my DRV8825s due to overheating. They would lose steps on larger jobs. Are you cooling them real well with a fan, or fans?
If I had room, I would build one of each! Hmmm...Maybe my laser build will also contain a drag knife mount. Thanks for the idea!
I like Estlcam. It is free, but I felt it was worth it so much I bought the license to help support further development. I love the probing...
The nice thing about the Workbee and sphinx - since they have the moving gantry - is that they both can cut things longer than the machine. You...
Put it in a v-shaped jig, use a drill press with a fence, find center, drill the center hole first, bolt/screw it to the jig so it won't roll, and...
I am not all that familiar with the smallest Shapeoko, but its cutting area is only 406 mmX406mm for $1149, so it does not meet your 500mmX500mm...
Fengrave is free and can draw bitmaps and dxf files. I use it for v-carving. However, I use Estlcam to draw dxf files on paper as a qc check...
