Information to build you own Onefinity Companion Control Box

Whats the cost of you to build one as close to plug in ready as possible?

Do you need to reprogram PD001 and PD002 on the VFD every time you switch sources or it’s not needed. What would be the value for PD001 and PD002? And would be the jumper settings, 1-2 short or 2-3 short?

I never reprogram those. PD001,002 define if your VFD will be control remotely (aka 1F) or from the VFD control panel. If you refering to my schema, the switch ‘Source Auto Mode’ enable you to choose if the SSR (for vacuum, pump, etc) will be controlled from 1F (pin 15, pin 25) or from VFD (pin FC, pin DCM).

Got it. Any reason or advantage switching source from the 1F controller or VFD to trigger that Auto mode? I will probably just stick with 1F controller to do the auto source.

Hi Ghislain!
Perhaps a stupid question from my side… But isn’t the pump supposed to be submerged in the cooling liquid? Or…?

With VFD I don’t need to adjust anything in the gcode and SSR is trigger few second more (i.e. during decrease speed ramp) so accessories (vacuum) run a longer time and the dust can better get out of hose.

With 1F, I thing, you need to adjust the gcode and this may be more complicated.

Also I don’t have a laser yet and I added this option to be able to switch accessories when using other option than the spindle/router. Example for the vacuum to get laser fume. I plan to put my vaccum out of my garage.

OK. I’m afraid I still don’t get it.

The design in your Etsy product shows the little pump unit inside the VFD encasing.

Three holes in the top of the encasing: 1 slit (for power cable?), and two holes (for incoming and outgoing hoses that are connected to the spindle?).

There’s a hole in the bottom too. Does that connect the pump to the reservoir? How?

Thank you for taking your time to guide me through. I really like your idea and I want to understand it so I can contemplate whether I want to add it to my setup. :slight_smile:

That make sense now. Thanks for the information.

Aaaahhhh, so item 4 is the reservoir!
Do you have an idea how much liquid it can contain, when taking the pump into account as well?

My setup is in function for a while and did not measure it on install. Today I removed my reservoir and empty it. I was able to see that some fluid was still in silicone tube and probably some liquid also in the little pump and spindle. Then reinstall the pump and fill with plumbing liquid. It was more difficult to reajust the silicone tube for not bending today than on first install.

I was able to add approx 1.5 liter of fluid. (excluding the liquid already in the system). Also I initialy bought 3.78liter of fluid and I figure I use approx 2 litre total (note that I don’t know how much fluid fall on my floor today during the procedure)

PD014 SET 1.5 – DEFINE ACCELATI0N TIME TO 1.5 SECOND (default was 10)

Updated my ETSY package with an extra faceplate stl file that as a laser icon instead of router icon. People that have already buy it can donwload it again or contact me from etsy to get it.

I have downloaded and built the box. Was curious of the purpose of the spacer that’s included in the files. It’s not shown in your documentation nor mentioned. Was it specific to your build or have you found it was needed?

Thanks for the effort.

Some people (probably related to filament type they used) had a warp on the back of the box. This was an acceptable solution having them not to reprint this part.

The second time I printed it, it printed the entire fan grill just fine. I used Prusa PLA filament on my MK3S+

Question, Ghislain: what did you use for hookup wire between the switches? The connectors you specify don’t really handle two 14ga wires; certainly not two stranded 14ga wires. I get the 18ga wire for logic-level signals but the 120v needs at least 14ga or am I just lost?

So…no answers here. I fell back to what I know about gauges and amperage. Load from NC should be 12GA. No need to wire both sides of the DPDT switches. Not sure why that’s indicated other than for redundancy but I couldn’t get any answers from anyone else. Still, it’s a good idea. There’s just a few gaps in the documentation but nothing that can’t be overcome.

Sorry I out of town for few week. I used SJOOW “CABTIRE” CABLE - 3C/14 AWG between swich and connector. I will look for specification again for the connector. Dual connection are for redundancy. For the gap, I appeciate if you point it out for me. Thank for your feedback
