if someone else is trying to do the same.
The driver board has just a BC 547 and a 5k6 resistor from the GPIO to the tranistor's base.

This is a short video of my setup: https://www.dropbox.com/s/y1u98e5fofup3qj/MF70.avi?dl=0

Re: LinuxCNC

Here is the hal_gpio driver to use directly the IO pins of the Raspberry Pi (V2 or V3 preferably), to add it just follow the same procedure from Kinsa in https://www.raspberrypi.org/forums/viewtopic.php?p=920778#p920778 and instead of the PICnc-v2 driver just complie the 2 files in attach: comp --co...

Here's the example hal for driving the gpios: https://github.com/machinekit/machineki ... o_demo.hal
Thanks, I'll have a go.
If it works I'll post a guide on how to use GPIO as well, my milling machine is a MF70/CNC ready

I have not used the gpio directly. Maybe you can ask jam1 for his hal file as he was able to control steppers using gpio only.
I think so,
I downloaded the image 2016-03-12-jessie-minibian and then followed your instructions.

Re: LinuxCNC

Kinsa, there is a discrepancy on your steps: the /boot/config.txt should be cd /boot echo kernel=$(ls kernel_rt*.img) >> config.txt echo device_tree=dtbs_rt/bcm2709-rpi-2-b.dtb >> config.txt instead of "echo dtoverlay=..." in fact in the sample just below is correct; I tried the dtoverlay but the RP...

Hi all, I am trying to use a Quanta touch screen too, I have the latest wheezy firmware (2012-10-28-wheezy), and I am developing an interface using QT 5. The kernel recognizes the touch screen: dmesg: [ 3.894495] usb 1-1.3: new full-speed USB device number 5 using dwc_otg [ 4.183387] usb 1-1.3: New ...
