SOLD - ShapeOko (assembled) plus extras

Lately my time has been eaten up with work and a 9 month old so I'd like to put my ShapeOko up for sale. It's the standard mechanical kit and it's running great. The power supply, grblshield, arduino, and motors are all included. I purchased the dual Y drive upgrade kit but have yet to assemble it a...

Re: random erratic behavior?

The extra air has worked wonders for me. Over a month later and it's still running fine, even for 2 to 3 hour jobs. The one problem I did have was when I turned on the shop vac in the middle of a job. There's only one circuit going to the garage.

Re: Grbl Controller 3.0 released

Oh yeah....it's awesome! The visualizer worked great on the 3 files I test printed from the RPi. Too slick!

Re: Grbl Controller 3.0 released

I finally got around to testing this out on the RPi tonight. Very slick Zapmaker! All cosmetic issues have been ironed out and the aggressive preload runs smooth. I did a few test runs at high feed rates (with spindle off) and it ran without any issues and only tapped the RPi cpu out at 50%. Great t...

4-pin JST SM Plug + Receptacle Cable Set at Adafruit

I saw Adafruit offers these now and thought they might be useful for wiring up motors. I'm using molex connectors which are cheap and work fine but they're big and ugly. I might get a few of these to try and tidy things up a bit.

Re: Shop Sign (First successful 3D Profiling)

Very nice! Thanks for sharing. I've been playing with poplar too since it's readily available at most hardware stores. I ran my first 3D profile this weekend more as a proof of concept. I used the same process of grabbing a Sketchup model then doing a roughing pass followed by a finishing horizontal...

Re: random erratic behavior?

I have improved my heatsink and fan setup to try to fix this issue, but am uncertain that I ahve a robust fix in place (see image of fan/heatsinks below) Levlandau2 - I've noticed that there's a pocket of slack air immediately in front of my fan. I had it sitting right on top of the heatsinks simil...

Re: random erratic behavior?

I upgraded to a larger 60mm fan and so far so good. I was never able to track down the exact CFMs of the old fans (gotta love surplus stores) but the new on is rated at over 23CFM which I suspect is 3x-4x more than the smaller ones. I need to run a few more cuts to make sure, but so far everything's...

Re: random erratic behavior?

I have heatsinks on each of the motor drivers along with a small 24v fan blowing directly onto the X and Y heatsinks. I also have another fan blowing between the grbl shield and Arduino. Perhaps the fans aren't putting out enough air. I'll get some faster ones and try them out.

Thanks,

random erratic behavior?

I believe my precision issues have been ironed out but now I'm getting another strange occurrence. After various periods of running, the spindle is sent way off into a seemingly random direction. The first pic shows a pocketed job (Misfits logo) that was on it's 3rd and final depth increment. About ...
