accelerometer probe on smoothieboard?

[KAS]

Is it possible to use the SeeMeCNC accelerator probe on smoothieboard?

[Jimustanguitar]

Also curious about this on Duet. Anybody know?

I don't have the accelerometer board yet but it should just work from what I've seen and read. Looking at the Configuration.h it simply interfaces to a single pin and looks like an endstop port and gives a simple binary on/off signal like a simple mechanical switch.

My understanding is that it uses an I2C interface...

I would think that would require some significant changes to repetier firmware to support? I looked at the repetier sources quickly and did not see anything out of the ordinary. This is where the pin is defined in Configuration.h:

Code: Select all

/* #################### Z-Probe configuration and Settings #####################
   These will change machine to machine, be sure to have the correct machine selected in the top of this config file
*/
// 301 = RAMBO    302 = MINI_RAMBO
#if MOTHERBOARD == 301
#define Z_PROBE_PIN 4
#elif MOTHERBOARD == 302
#define Z_PROBE_PIN 16
#endif

I've never quit figured out how repetier firmware maps to pins defined at http://reprap.org/wiki/Rambo_development (and it has been several years since I've used a RAMBo).

Hey - you have a V3! Where does it plug into RAMBo and how many pins does it use?

[mhackney]

Yup, I2C http://seemecnc.dozuki.com/Guide/Step+4 ... ssembly/44

I looked at the sources again and still did not find anything special to support the probe.

[geneb]

I took all those pics...so yeah.

Show off.

What do you know about the code to support the probe?

[KAS]

Okay, well at least it's possible since smoothie has an I2C header. Hopefully the coding is something simple.

I don't know anything about it. I think the next most knowledgeable guy is Kraegar....or bug Guanu.
