Re: LinuxCNC

@ Hybris I would not think that chip is capable of delivering the necessary power to a nema 23 series stepper to achieve anything close to maximum rated dynamic torque especially in a micro stepping mode. It all rather depends on how fast you expect it to go and a load of other stuff as well. It wil...

Re: LinuxCNC

Had some more probs with the compile, not sure what actually may have been built/installed/left over..? Gave up on that given the binary now published. So, I've installed your binary of openOCD for RPi. The dir & file structure look to be as expected. Created the configs as per wiki and checked the ...

Re: LinuxCNC

Thanks for posting this and doing the work to make it happen! Much appreciated. I have just ordered some bit & bobs to build one! BTW Do you have general recommended values for R , R1 , C for the MCLR pin And C value for Vcap pin Or are they device specific, and need to be derived from PIC datasheet...

Really looking forward to the details on the PIC. I hope to try it out as soon as practical

I had been following the thread on the Linuxcnc forum with mixed feelings, but you seem to have cracked it.

Hmmm but Eckler's clause on contributions puts me off. (Something along the lines of "all contributions will be copyright of ecklersoft"), can't find it on his website at the moment...

Everything was done with the rtstepperemc software from Ecklersoft, and /or compiled from sourcecode from Ecklersoft download area.

Re: avrsetup not working anymore?

Bingo..! The quick and dirty hack of changing the sig to 0x14 in avrdude.conf worked. Blinky is blinking again :) This will do fine as I now have several 328-PU devices (Well for now) To anyone doing this, avrdude.conf is a really big file.! The 328p section is a little past half way down. Many thanks
