Re: What is my problem here?

My Belts are held in place with 2 zip ties, and are pretty tight. They only deflect about 1cm when I place the weight of my entire hand on them and they are uniformly so. When I put them on, I checked to make sure they weren't too tight. If they are too tight it didn't seem to move at all. This was ...

Re: What is my problem here?

I thought I had posted this update, but I kinda got something working: I added another motor to my Y axis to support my gantry on both sides and fixed up my slipping Z-axis and took all your advice and got something that worked (kinda). https://dl.dropboxusercontent.com/u/6405154/Selection_877.png I...

Re: What is my problem here?

Thanks for all the tips guys! here's my plan: 1. Make the traces wider. 2. Decrease the depth to 0.002" or so. I didn't even think about it, but yea, 0.0035 IS half of the 0.006-ish PCB material. duh! I must have misplaced a 0 when I was thinking about it. I'm used to metric too, so I'm not used to ...

Re: What is my problem here?

I've been having trouble figuring out how to get my Z depths correct, you can see my questions on the pcb-gcode forum about that... My workflow is EagleCAD 6 --> pcb-gcode (latest) --> Autoleveller.jar (from autoleveller.co.uk) --> linuxCNC. in PCB-gcode, I set my depths to be 0.035" below the surfa...

Would you mind posting this modified milling code? This seems easier than adjusting the feed rate.

Re: What is my problem here?

Thanks for the reply. I plan on hand-soldering this one. If you look at the tool path in a gcode visualizer does it appear to have the trace sizes you are getting? The single pass I got looks like the width of all 5 passes in the simulator. I had attempted at a z Depth of 0.07" which was default whe...

What is my problem here?

I'm using eagle to design the PCB, exporting it using pcb-gcode (latest version) Then running the autoleveller form autoleveller.co.uk and here are my results. https://dl.dropboxusercontent.com/u/6405154/issues.png I expected it to be a little gnarly, but this is completely unusable. I only ran 1 of...

Re: Concave side of bearing?

The wobble was driving me nuts. I built my machine last summer when the first batch of Shapeokos went out, but haven't had time to test or use it until now (I still technically don't have time and should be working on other things...) Anyway, I was trying to level my worktable by milling it flat (Pl...

Re: Printing in G-code

I realize this is a bit old, but I finally got the parts to add a 4th axis to my hobbyCNC Pro motor driver board. I am using LinuxCNC for milling and I'd lie to use this for 3d Printing as well. Does anyone have suggestions in this setup? I am still missing something for controlling the temperature ...
