TaylorPilot,
You will likely be fine with one IPC-5 but good to leave space for two, just in case.


RogDC,
Good example regarding power supply sizing for your machine. Thanks

There has been some confusion and misinformation lately regarding the resistors used for the ClearPath step and direction inputs. The C86ACCP board is designed so that it does not need any added resistors.

Additionally and for a number of reasons, I have to retract the advice given for the step and direction lines. There may be a more formal update from Centroid coming soon but here is some informaton for now regarding open collector inputs sent to ClearPath motors:

5VDC = 1k ohm 1/4watt resistors for step and direction
24VDC = 1k ohm 2 watt resistors for step and direction

The recomendation to use 10k ohm resisitors was prior to doing some testing with an o-scope so my sincere apologies for the confusion and misinformation.

Tom,

Thanks so much for your continued involvement. I’m super excited to see such attention given to the acorn+clearpath combination.

Thanks,
Clay

Would be nice if one of are users proficient with CAD and 3D printing could design and make some brackets for it.
Anyone? Anyone? :D
I'll have you covered! I'm going to be using the C86ACCP will be making a 3d printable bracket for it. I'll also provide the general dimensions of the combination that will be derived from 3D scan and hopefully a C86ACCP solid model.

Thanks,

Clay, sounds good. Keep the bracket slim and functional. Post the .STL file here when you are done with it. THANKS!

Marty,

I just wanted to take a second to share my SDSK build, runs great. I used acorn also, I'm adding coolant, touch probes and home proxes next!

Thanks.

I see that you powered acorn via a separate power supply. Any particular reason for that? I have been planning on using a 5amp 24v power supply for all of my power needs including the power hub and relay coils.

Marty,

If I understood your video correctly, the output of your IPC-5 goes through your E-stop contactor. If that is correct, I see an issue with this approach. If you hit e-stop while the machine is moving quickly and the motors start dumping energy because they are being driven my moving mechanical systems, that regenerative energy cannot return to the IPC-5 which has circuitry to deal with regenerative energy (big capacitors). I believe this can cause an over voltage situation on your clearpath servos and potentially damage them. I think the appropriate solution would be to have the AC Input of your the IPC-5 power supply switch via the contactor to preserve the path from
Motors->power hub-> IPC-5.

Thoughts?

Enjoying the series. My question is, would it be acceptable to just wire the e stop to kill power to the entire cabinet. i could see a situation where the board or one of the power supplies malfunctioned and start to make magic smoke, and shutting off the power would be a better solution. I guess my question is, what is the advantage to doing it this way, instead of just killing power to everything at once?
