Re: LinuxCNC

Hello,

I have a few of my RASPI Kits available, if interested. You can see my project/application here: http://ki4sbl.dodropin.org/CNCTRK/ . Look for the RASPI Kit down the page. The kit included everything needed for the PICnc-v2, including the RPi B+ and some extras.

Have fun!
Bob

Re: LinuxCNC

kinsa, Has been a while since I compiled a kernel but I have been giving it a try - just for the re-education. In doing this I found the .config used for my current kernel does, indeed, have USB wireless enabled ad several devices (including one device I have) are compiled as modules. I proceeded to...

Re: LinuxCNC

Thank you for the tip. The dwg_otg.speed=1 setting improves things considerably, though still slower than previous. Am having trouble getting machinekit operational with the rt-preempt image. The PICnc LED rate increases on loading the CNC program, as usual, but have not observed any motion and am g...

Re: LinuxCNC

Hello, All, Perhaps, I am missing something but, so far, this new machinekit install is not usable fo me on a model B+ pi. I installed using both cases, standard raspian and the minibian. The latter was more responsive, as expected, but still quite dreadful. Digging around the net I found this discu...

Re: LinuxCNC

Regarding the addition of Wi-Fi drivers in a new image, here are a couple that I would like to see included: 1. From the CanaKit, RPi 2 model B kit using the RT5370 chipset 2. Kootek #KT-RPWF using the Realtek RTL8188CUS chipset These were purchased from Amazon. Information on other/better choices i...

Re: LinuxCNC

Hello, Have a question for the group. Are drivers for USB wi-fi dongles included in the RPi and RPi2 images? Have folks had any success and, if so, what devices or chipsets were used? Am looking to add this network interface for occasional use on my system. Kinsa, I just saw your response to candang...

Re: LinuxCNC

This is what I find on two laptops. I'll confess to not knowing the full impact if the settings, other than its impact on maximum speed of an axis. My application does not require high speed.

Re: LinuxCNC

Hello, Happy camper here as I just got my machine up and running. I did learn a thing or two along the way, as always. Am posting my experience just in case someone encounters similar hurdles. Using a PICnc-V2 (LPT version) and RPi B+, I followed instructions in the following two links to load an im...

Re: LinuxCNC

Hello, Am new to this forum and first want to say thank you to Kinsa for the picnc-V2 board and all the effort that has gone into getting LinuxCNC running in the RPi. I have several years experience with the LinuxNC and am now trying to implement this system. I am writing to request clarification on...
