Hey chaps,

So I'm running out of outputs on my mesa 7i95t I have loads of inputs free. 

So my question is can the input pins be used as outputs?  If so how.

I have 6 ssr outputs on the card all are used for loads such as solenoids and relays.

I now need outputs (24v) for my drivers enable/alarm clearing functions.

I have ordered a 5 axis bob but it seems they are all inputs not outputs.

Any suggestions on how to get more 24v outputs? 

Thanks. Yes. This is what I have. Thank you.

Is this enough?

For that board to work with the inputs you will have to connect a 12-24V supply to the terminals on the relay side of the board.

 I am using byte2bot and currently trying to use homing. I pressed the limit switch, but it still doesn’t trigger the homing. 
Regardless of whether I press the limit switch or not, it always returns TRUE.(Like the attached picture.)
Here are my HAL and INI files.

Hi Kam,
thanks

the warning and BadWindow stuff can be ignored

Cheers

controlword and statusword are part of the cia402 standard. We write to control word and read the results in status word. Just look at the examples and make sure you have the ones that connect to cia402.comp.

Use AI to get a tutorial on cia402 state machine. your manual is saying there is a 32 bit value (2 x 16 bit values) and it rx (receives a value) so it is an S32 in pin in hal
 

cool entered those. no change. (which i assume is expected)

I am looking at these hex things. where do i find the values? in the drive manual it lists them and then says the range.

eample:

<pdoEntry idx="6040" subIdx="00" bitLen="16" halPin="cia-controlword" halType="u32"/>
<pdoEntry idx="6060" subIdx="00" bitLen="8" halPin="opmode" halType="s32"/>

I actually registered here to say: Wow, really impressive work with the trajectory planner! looking forward to see it evolve.

We put the clothoid fitting algo in a seperate thread.

Creating a lockless, thread-save producer-consumer queue has a lot of pitfalls, I would recommend looking at this implementation  Lock-Free Single-Producer - Single Consumer Circular Queue    or in C  

 Besides that can I ask if the points raised by hmnijp ( smoothed polyline segmentation causing deviations, page 3) are addressed with the use of clothoid-curves? I guess to really have jerk limiting you not only need to be smooth in the time domain but also in the path, thus the use of clothoid(?)

For my 9x20 spindle, I used optical sensors and cut 65 teeth into a thin disk. With two carefully offset sensors I get 260 quadrature counts and haven't had any problems threading 120-150 rpm. A third optical sensor provides the index from a deeper tooth.

I ordered an omron encoder off eBay ($20) that will be a lot cleaner. When I get around to installing it I will probably 3d print gears for a small belt running around spindle and encoder. If you go this route don't go over board on pulses per revolution. 1024 ppr will be more than enough for threading.

The most difficult part of my 9x20 conversion was the modifications to fit a small ball screw under the cross slide good luck!
