Re: Cherry Pi III Is Available
My understanding is that you can connect to your Arduino from the Arduino IDE using a particular baud rate and COM port and you can successfully upload the firmware? If this is the case then you HAVE...

Nice work! I'm currently contemplating building a similar size delta. When looking at various designs I noticed the difference how 2040 extrusions are used. In your design the long side points to the...

Re: Cherry Pi III Is Available
There's no Baud Rate into the IDE. Sadly, my Arduino is far from my computer, so I can't show you EXACTLY, but I'll try to help you the most I can. If you open the Marlin.ino for the Arduino, look at...

My endstops, and hence my firmware were set to be normally open I.e the outermost pins on the switch used and firmware set to 'false'

Ahh.. flipping might be an option :-) I'll try that. Thanks Thomas

Woo hoo, more noise and stuff! Unfortunately that's the extent of my success lol. It didn't go for the kill() after I inverted the endstops (thanks Sebastian) however it didn't move a whole lot. I...

Sweet mother of mercy that looks magnificent. Once I get bored of my CPIII I'll make the jump to this one. Would be a nice upgrade for a few printed bits and some extrusion.

Setting the trimpots on the stepper motor drivers seems to be your next step. Time to dust off your multimeter..... :)

I determined that my steppers were wired badly. *sigh* Fixed it. But it still failed. So... uh... anyone want to buy a CP3? Haha.

Your almost there. After that, you'll be able to print (if you're in a hurry), but you'll also need to do a calibration. As Andy said, trigger a "G30 A" and then fine tune with M666 ( [www.youtube.com] )

Hi Andrew You're nearly there. In terms of checking your stepper connections. I usually make a small 'U' of single core cable and insert it into first the left hand pair of holes in the stepper plug...

My first ever Cherry Pi design used counter sunk magnets and steel balls. The holding force was never enough. I never tried countersunk with magnetic balls as by that time I had started to use the...

Thanks for the support guys. :) Yep, I'm going to check my stepper connections again. Some of my earlier crimps were of questionable quality so that could be an issue for sure. Fortunately I got a...
