What kind of controller are you using? I had a similar issue with xPro CNC Controller. One of the Y axis drivers would go into thermal shutdown....
Josh, you should start your own build thread so it doesn't get lost in the main Ox thread. I finally did with mine (Cebu) and it was nice to be...
Follow directions here: https://github.com/grbl/grbl/wiki/Compiling-Grbl It's super simple to do via the Arduino IDE. Very quick, I was up and...
I know there are people on the openbuilds forums that have a tinyg and xpro for sale. I personally use xpro, and have been very happy with it.
If you went with something like the tinyg or xPro CNC controller, you would only need to add motors and a power supply. Looks like with the item...
I think that's probably overkill... That is a 388 oz. motor!
I'm using 223 oz. NEMA 23, and it is plenty of torque. I would feel comfortable using a full size router with this. Currently have a Makita...
Okay, I figured out a part of the problem. On the Y gantry plates, one of the eccentrics needed adjustment, as the bottom wheel was not making...
I think in 0.9i, instead of enable it uses PWM output, from 0-5v. You might need to send M3 with speed to increase the voltage? What happens if...
What version of GRBL are you running?
As I have started using my Ox (Cebu) more, I've noticed some flex in the z axis. At first I thought it was the x axis beams, and was planning to...
I have about $1,200 invested in mine. I made mine a bit larger than the "standard" Ox, which added incrementally to the cost. I did use an...
I had problems with GRBL Controller, and ended up using Universal Gcode Sender instead. Can you try connecting with that?
Quick addendum to the GRBL config for the xpro. The TI drivers that are used have a minimum step pulse width of 1.9 usec, so the default GRBL...
You are on the wrong tab on the spreadsheet! There are two - the BOM tab, and the Stepper + Calculator. Look for the other tab on the bottom of...
Hmm, I just tried it, and it worked for me. You only fill in the yellow boxes at the top, and it calculates everything below.
I ended up using self tapping screws for my build instead of tapping for M5 screws. Saved a bunch of time, and didn't have to predrill or...
Here are specs on belts from sdp-si.com. I believe the belts from Openbuilds are GT2 3mm pitch - figure 19h. [ATTACH]
I didn't keep complete track, but mostly stayed true to the output of @Serge E. OxCalculator. I put in the sizes I wanted, and used this output...
Yes, that will do it. In newer versions of GRBL (0.9i) they've done away with the auto start option all together, so there is no more $14. -- John
