@Scotty Orr I released the compression on one of the lead screws and it reduced the whip significantly. At least to the point where I don’t fear...
Hi I'm working on a Sphinx style CNC machine with a 1000x1000 footprint. Those of you who have made a similar machine, do you experience a lot...
I've done a bunch tightening. The new lead screw has arrived and I ordered a set of DM542 drivers. To be honest, the DRV8825 are doing a pretty...
BOM - bill of materials Lots of things to learn when embarking on an adventure like this.
If you have a well running Sphinx cnc (or a similar leadscrew design) what Grbl settings and microstepping are you using? Just want to know what...
For maximum rigidity you probably want to go with chris’s me modifiied z plates that use full sized wheels on the outside. You would need to...
Did some more tuning and found weird slack in my Y's. So I ran the gantry back and forth and one of the lead screws is bent. :-( Just ordered a...
Got Z up and running and made a few cuts. Since the waste board isn't attached Z is all over the place but otherwise it looks pretty good. Also...
So far so good. I seems to draw pretty accurately. I'm not having that much much with Chilipeppr at the moment. It seems like half the widgets on...
It's alive! I wired up X/Y and that found one of the DRV8825 was broken. One of the Y-screews simply didn't travel the same distance as it's...
That sounds like a well engineered solution. I do believe it is beyond my machining toolset (not to mention skill-set). I think I'll try adding...
Hi I'm building a Sphinx style CNC and have problems attaching the pulley to the lead screw on Z. It simply seems to be loose. The first time I...
Finished the base frame. Originally I was planning to follow @Kyo's original design but with 80x20 as a frame and 60x20 as supports. Then I hade a...
Added 0.2mm shims (from an old soda can) to X beam, a lot squarer now but then the next problem surfaced... I originally squared the base with the...
Looks cool, it will be interesting to see your results!
When I pull my gantry all the way back to the plates I get a gap of about 3mm on one side. You can look at the pictures.. Any suggestions? I'm...
Build has been slow since I blew my back and have to take it easy for a while. I removed the Lead screws from Y in order to check for any...
More work with the assembly. Spent quite some time shimming in order to get proper angles. It's time to start thinking about wiring. I'm to lazy...
Began assembly. Attached all the axes and started working on the frame. At this point I have an 1-axis CNC.
Did as much assembly as possible on X. It seems like when using Chris plates you can't use a 1mm shim on the outside. Otherwise the lock nuts...
